Thanksgiving-Eve Storm
Overview
As most everybody has probably heard by now, we have a strong storm heading up the east coast tomorrow (11/26), and lasting through the day on Wednesday. Originally, at the beginning of last week, model runs were showing a possible snowstorm. Unfortunately, as the days went on, that threat went away and a rainstorm is what is left for South Jersey and Philadelphia.
Timing
Some scattered showers and rain out ahead of the system may start affecting us tomorrow afternoon, but the main bulk of the rain should arrive in the evening, around 5-8PM. This rain will be heavy and persistent, as it will last into the day on Wednesday. As the precipitation begins to taper off in the later afternoon/evening, the rain may mix in with some snow or changeover to some light flurries/snow showers toward the end of the storm, as cold air begins to wrap around the low into our area.
How Much?
Right now, it appears like this system will be a soaker, bringing 2-4 inches of rain to the region, with more possible in localized areas. Any flurries, if a changeover occurs at all, will almost certainly not accumulate into anything. The only areas that will experience snow are the Poconos and interior portions of Pennsylvania, well west of Philadelphia. At the bottom of the post is a QPF (Quantitative Precipitation Forecast) map from the National Weather Service, which shows a model forecast for liquid precipitation amounts.
Other Effects
Of course, the main concern with this storm is the impact that it will have on travel during one of the biggest travel time periods of the year. Anywhere from the Gulf Coast to Maine will see severe travel problems due to rain, wind, and snow. Locally, other than rain, we could see wind gusts up to 30mph and some tidal flooding. Temperatures tomorrow will be one of those abnormal times when temperatures increase throughout the night. We will see mid-40's during the day, tomorrow, that will increase into the 50's during the night, giving us highs in the mid-50's on Wednesday. Then, as the storm moves through, cold air will plunge in, bringing highs into the 30's on Thursday and Friday.

Storm Update
Well, Karen has dissipated in the Gulf of Mexico before even making a landfall...however, her remnants will become absorbed into the cold front that is moving through tomorrow.
Timing
Scattered showers are possible tomorrow morning into the afternoon, out ahead of the front. The main line of rain and storms is expected to pass through in the late afternoon/evening and last until around midnight. We should wake up to sun and clouds on Tuesday, though!
Effects
-Expect .5-2 inches of rain across the area, with some places possibly receiving more
-Winds up to 20-25mph
-Wave heights up to 6 to 7 feet
-Localized minor flooding due to quick/heavy rainfall on dry land

Effects of Tropical Storm Karen
Current Information (2pm EDT Advisory)
Max Winds: 50mph
Minimum Pressure: 1003mb
Moving NNW at 9mph
Current Forecast Track
Source: http://www.nhc.noaa.gov/graphics_at2.shtml?gm_track#contents
7-Day Precipitation Forecast
The above maps show both the track and the 7-day precipitation forecast from today, October 4th, until October 11th, which encompasses the time in which Tropical Storm Karen's remnants will affect southern New Jersey. Now, not only will we be dealing with Karen's remnants, but the current winter storm in the northern Plains and Northwestern US will be moving across the nation as the cold front associated with it will move through New Jersey around the same time as the tropical storm's remnants. Below, I will explain what each of the main models is saying. Finally, the last section will include what to expect, as of now, with regards to how much rain and any other effects, like winds and wave heights.
GFS
The GFS's latest run from this afternoon currently has Karen moving northward toward Louisiana before hooking to the east, moving along the Gulf Coast, and then making a main landfall in the Florida panhandle. From there, Karen will then essentially meet up with the cold front, as she becomes extratropical and blends into the front. All together, this run has the precipitation beginning on Monday night and lasting into Tuesday evening, before clearing out.
EURO
The European model run shows a less intense storm as it makes landfall along the Gulf Coast, with less moisture and higher pressure. The storm then takes roughly the same trek, as described in the paragraph above, but the timing is a little later and provides less precipitation for our area. The timing would be early Tuesday morning into Tuesday night.
Summary
All together, we are looking at a decent soaking from the combination of the cold front and remnants of Tropical Storm Karen. Timing-wise, expect scattered showers to move in on Monday out ahead of the storms, with the main bulk of rain occurring between Monday night and Tuesday afternoon. The chance of showers should dwindle as the evening/night progresses on Tuesday. Rainfall amounts, naturally, will vary from location to location, but 1"-3" of rain should be expected at this time, with totals on either side of that range still being possible. Finallly, though the rain should be the worst of it, sustained wind speeds are forecasted at 14-20mph, with gusts up to 30-35mph, and winds will be faster down the shore as there is no friction coming off the ocean to slow the flow of air. Then, wave heights are currently forecasted to be in the 4-7 ft. range. We are still 72-84 hours out, so if anything changes, I will post an update. If I had to guess how the forecast would change if it did, I would say that the storm, in general, would come in less intense, but time will tell.

Furthermore, New Jersey's second tornado of the year(we average 3 per year) touched down on the morning of Tuesday, August 13th around 10:05am near Manahawkin, NJ. It was an EF0, with estimated winds of 75-85mph, a path width of 50-100 yards, and a path length of 2 miles. Fortunately, there were no fatalities or injuries, and the damage extended to downed trees and damaged roofs.
Finally, outside of New Jersey, the Atlantic Hurricane Season is heading toward its peak, it seems to be heating up. Two areas are under investigation: Invest 92 and Invest 93. Invest 92 is located in the Caribbean Sea and currently has a moderate chance(30%) of becoming a tropical system in the next 48 hours. Invest 93 is located off the coast of Africa, with a moderate chance(40%) of development into a tropical system within the next 48 hours.

Tropical Storm Andrea Update #2
Tropical Storm Andrea made landfall in Dixie County, Florida this evening. As of 5pm, the storm was around 856 miles southwest of Philadelphia with winds of 65mph, an air pressure of 993mb, and moving northeast at 17mph. Andrea is still forecasted to track up the Atlantic seaboard and move over New Jersey on Friday. It will bring up to a couple inches of rain to our area with locally higher amounts of precipitations, which gives us the threat of flooding. Furthermore, there will be some gusty winds, mainly along the shore points, and the risk of storm surge and wave heights will be low.

New Forecast Visuals
I'm going to start a new way of doing forecasts now that I have more time at home for the Summer. I'll be using a program called 'GEMPAK' that allows me to create my own weather maps, so it will give a visual way of presenting forecasts instead of just text. I'll give maps out to three days using the NAM model, which is a short-range model, and these map will give temperatures and air pressure for 2pm, and precipitation totals from 8am to 8pm for each day. I will also post maps and text updates of severe weather when necessary. I'm hoping to start this by the weekend.
Here is an early example for tomorrow, Wednesday, May22nd:

General Weather Misconceptions
Monsoon
This one is one of the most popular misconceptions that I have heard growing up, and it is that people associate a heavy rain event with being a monsoon. Yes, a monsoon is the cause of an intense rainy season and can bring a lot of rain, but it also leads to a dry season as well. Simply put, a monsoon is a seasonal reversal of the wind pattern that is accompanied by changes in precipitation and winds.
Essentially, a monsoon is caused by the difference in heating of land and water surfaces at different times of the year because each surface absorbs heat differently. The water absorbs a lot more heat in order for it to change temperature, whereas the land takes less heat to change the temperature. Therefore, during the warm months, the land heats up quicker than the sea causing the atmospheric gases to expand there providing lower pressure over land and higher pressure over the water. This then results in moist air flowing from the sea to the land, called a sea breeze, and the air then rises and condenses to bring large amounts of precipitation in the 'rainy season'.
The opposite occurs in the colder months when the lands cools faster than the sea. Here, low pressure occurs over the water due to it being warmer, and air flows from the high pressure over land to the sea, called a land breeze. Dry conditions then occur over land and precipitation falls over the water, which is why it is called the 'dry season' on land.
This process is what is seen along the New Jersey shore but to a smaller and less intense scale.

Lightning
Contrary to what is commonly believed, lightning can in fact strike the same place more than once and also does not always strike the ground
First, lightning is an electrical discharge when there is a buildup of opposite electrical charges, and lightning is what occurs as the process that tries to make the electrical distribution equal. To get onto the misconception, lightning can strike the same place, or human for that matter, more than once. That is because electrical charges do not have a memory and can not know where a lightning strike has occurred before.
Furthermore, lightning does necessarily have to strike the ground. Differences in electrical charge can form within a cloud, between two different clouds, between a cloud and the air, or between the cloud and the surface. Therefore, you can have four different types of lightning: intra-cloud(within a cloud), cloud-to-cloud lightning, cloud-to-air lightning, and cloud-to-ground lightning.
Finally, the method to tell how far away a storm is from you is called the 'flash bang method'. Count the number of seconds between the lightning flash and thunder, then divide by five, and that is how many miles the storm is from your location.

You can see the faint contrast of the circle of the halo against the grayish-blue sky. Halos are cause by ice crystals in the atmosphere refracting, or bending, light rays toward the observers eyes. The result is a halo, like the one above.

Snow Totals from the 3/25 Snowfall

Small Update to Snow Map
Here is the small update to my map with the chances for more snowfall in South Jersey and Philadelphia...
5-Day Forecast and 3/24-3/25 Snowstorm Threat
5-Day Forecast
Sunday: partly cloudy with rain/snow showers late; highs in the upper-40's
Monday: rain/snow, windy; highs in the mid to upper-30's
Tuesday: storm clears out, turning to sun and clouds; highs in the mid-40's
Wednesday: partly cloudy; highs in the upper-40's
Thursday: partly cloudy; highs around 50°
Snowstorm Threat
Well, the GFS was right from my post several days ago...as of right now, all the main models agree on our area receiving at least a light snowfall event. A low from the Midwest and one from the east coast will move through the area and phase, or merge, off the coast and intensify. The timing for this would be an arrival late on Sunday night and an exit late Monday into Tuesday morning. Late Sunday night will bring snow and rain showers, which will persist into Monday when it will turn to snow with snow showers tapering off west to east late Monday or early Tuesday morning. With temperatures being so close to freezing and above, rain and sleet could mix in or change over throughout the day.
As with any wintry event in March, there is great uncertainty and skepticism with snowfall, and this storm is no different, as temperatures are warmer at the surface and chances for a bust in snowfall are higher than in the winter. Most accumulation would be on grassy surfaces with temperatures on paved surfaces being too high to support much in the way of snow accumulation. There is also the possibility of this storm throwing snow bands back into the area after it is supposed to exit, just as the last storm in early-March did and gave NJ a decent amount of unexpected snow, just as a heads up.
The coast will probably not see much of accumulating snow due to temperatures being too high with an onshore flow and rain/mixing, keeping any accumulation minimal, most likely. The further west you go in South Jersey, the best chances for higher accumulations. Models give the Philadelphia/South Jersey area around one inch of precipitation, but it is almost impossible to predict how much of that will attribute to accumulated snowfall until the storm is in progress, depending on ground temperatures, how much snow melts away on impact, and how much snow actually falls during the storm.
Finally, for snow totals, most sources mainly give a couple inches to our area, but the possibility of no accumulation is, of course, there this late in March. The GFS and EURO each give our area a couple inches of snow. The NAM hammers us with a major snowstorm and gives us up to a foot of snow, but that is wishful thinking. Right now, I believe that non-coastal New Jersey and Philadelphia will see accumulating snow but just some small accumulations. I'll post a few snow total forecasts, then give my map...

5-Day Forecast and Storm Threat Outlook
Here is my forecast for the next five days that will take us to the end of my, and a lot of others', spring break...
Tuesday: lingering showers in the morning give way to sun and clouds in the afternoon, windy; highs around 50°
Wednesday: sunny; highs in the mid-40's
Thursday: chance of flurries and snow showers in the early morning, then partly cloudy; highs around 40°
Friday: partly cloudy; highs in the lower-40's
Saturday: partly cloudy; highs in the mid-40's
Outlook
Spring arrives on March 20th with the vernal equinox, which is only one of two times a year where the sun is directly over the equator. In Philadelphia, and the rest of the region, day is now longer than night, and the time of sunset is pushed back later everyday from here on out into June, which I love! However, after looking at the models, it doesn't seem like spring-like temperatures will be arriving within the next two weeks. Unfortunately, there is no tell-tale sign of higher temperatures, a ridge in the pressure heights map, on the horizon, and it seems like temperatures will not make it past the lower 50's within the next 10 days.

Furthermore, looking down the road, I see two storm threats within the next couple of weeks: one on my birthday, March 25th, and the other on April 2nd. The one for March 25th would be a cold, rainstorm as it looks now, if it hits us...maybe if it was a few moths ago, I'd be more enthusiastic for snow, but it's just too warm now, especially on ground surfaces for much in the way of snow to fall and accumulate. The GFS gives our area a direct hit, but the EURO takes the storm a couple hundred miles south along the Virginia/North Carolina border. We'll have to see which model caves in to the other, and it is usually the EURO that wins out.
Also, the latest EURO run stops just short of modeling the April 2nd storm, but it definitely shows a coastal storm developing. The GFS models the storm as giving our area a good dousing of rain, but it, of course, is very far out at 14 days, so I'll just keep an eye on it.
Anyway, enjoy the next several sunny days, and hopefully higher temperatures begin to show up sooner than later!

Early Spring Break Outlook and 5-Day Forecast
Spring Break Outlook
With spring break at Rutgers (March 16-24), and many other schools, starting in a couple days, I wanted to post an outlook for what the weather will be like for our days at home. Unfortunately, it doesn't seem like spring break will exactly have spring-like temperatures, but it looks like it will have spring-like precipitation for our area. For the outlook, I used a combination of the GFS and EURO, with a bias toward the EURO, of course, since it is the best weather model, but the GFS goes out further. For reference, the average highs, for mid-March in Philadelphia, are in the lower-50's, and March is Philadelphia's second-wettest month, according to weather.com.
Saturday: showers, about a tenth of an inch of rain; highs in the upper-40's
Sunday: cloudy with some sun; rain and snow showers at night, highs in the lower-40's
Monday: rain, up to an inch of rains; highs in the mid-40's
Tuesday: system exits, showers in the morning; highs in the upper-40's
Wednesday: clouds and sun; highs in the lower 40's
Thursday: showers moving in toward the night; highs in the mid-40's
Friday: rain; highs in the 50's
Saturday: rain; highs in the upper-50's
Sunday: wet weather clears out; highs in the 40's
About the system on Tuesday...a few days ago, the euro was modeling it as a major snowstorm for our area and the rest of the northeast. That is no longer true. The possibility is not completely gone, but a bunch of factors work against a high-accumulation snowstorm in March due to the high sun angle and warmer ground surfaces. Furthermore, the GFS never jumped on-board with the euro for a snowstorm, and the euro has now modeled a mainly rainstorm for the past few runs, now. It is still around a week away, so anything can still happen, though. As of now, it looks like a lot of rain for Monday/Tuesday.

Thursday: partly cloudy, windy; highs around 40
Friday: mostly cloudy; highs in the mid-40's

Thursday: partly cloudy, windy; highs around 40
Friday: mostly cloudy; highs in the mid-40's
Saturday: showers, around a tenth of an inch of rain; highs in the upper 40's
Sunday: clouds with some sun, giving way to snow and rain showers toward nightfall; highs in the lower-40's
Monday: rain, up to an inch; highs in the mid-40's

3/7-3/8 Snow Totals and Upcoming Forecast
Storm Snow Totals
Well, the snowstorm that wasn't ended up turning into the snowstorm that was. After the low pressure system stayed to our south and didn't give our area much precipitation, except for the shore points, it moved offshore and drifted northeastward, only to stall. It was due to this stalling that snow bands were able to wrap around the low and come into New Jersey and Philadelphia from the northeast. This was actually modeled to happen, except to a lesser extent as accumulations ended up at least doubling or tripling predictions in a lot of places. Here are snow accumulation totals from southeast Pennsylvania and South/Central New Jersey from the National Weather Service...note that a lot of these are from the morning before the snow ended, as the times of the measurements are listed next to each town:
Snow Total Prediction
Before I get to a very nice weekend forecast for the area, I want to explain how I come up with predicted snow totals and why snow accumulation can be so hard to predict. Models like the EURO, GFS, and NAM all have runs where precipitation amounts are outputs that are displayed on a map using different colors for different ranges of values. This output of precipitation values is called QPF, or quantitative precipitation forecast, which is the amount of liquid water precipitation that an area is projected to receive.
Once you get the QPF, you use a snow conversion table where liquid water amount, in inches, can be converted to snow amount, in inches. However, this is dependent on air temperature. The higher the temperature, the denser the snow, and the more it will compact together on the surface, causing a smaller snow accumulation than at colder temperatures. Conversely, the colder the temperature, the fluffier the snow, and the accumulation on the ground will be greater because the snow pack on the ground is less dense and compacted. Heavy, wet snow is good for snowballs, and fluffy snow is easier to shovel but not good for snowball-making. Here is a liquid water to snow ratio chart:
This is not the end of predicting snow accumulation, though. Several factors go into predicting totals. First, you need to know the QPF and liquid to snow ratio, along with the air temperature during snowfall. Second, you need to know where the rain/snow line will set up and move during the storm, as rain, sleet, and freezing rain dampen snow accumulations quickly. Third, you must know the ground temperatures, because if they are above-freezing, then it will take heavy snowfall or take time for cold air to cool the surface and get snow to stick to the ground. Fourth, the track of the storm is quite an obvious one that you must know. Then, finally, the set up of heavy snow bands within the snowstorm can cause 'jackpot' areas of localized, heavier accumulations relative to surrounding areas. These are main factors in predicting snow accumulations, and some of these caused problems with forecasting Wednesday's storm.
5-Day Forecast
Finally, we get to the forecast for the next week...After a messy and cold couple of days, we'll be rewarded with a sunny weekend for Saturday and Sunday, with highs in the mid to upper-50's. On Monday, clouds will move in, accompanied by a high of around 60. Showers on Tuesday, modeled to bring around a quarter of an inch of rain, with highs in the mid-50's. Then, it will clear out for Wednesday, leaving behind a nice day with highs in the lower-50's.

Yet Another Snowfall Disappointment
In a winter full of disappointment for snow in New Jersey and Philadelphia, we have yet another bust for snow, or at least as much of a bust as you can have when there was so much uncertainty. Contrary to the models and what was expected, the storm and main bulk of precipitation stayed south and moved east, rather than northeast. This meant that a constant onshore, warm flow kept any precipitation as rain until late last night when the storm finally moved northeastward and rain showers changed to snow showers. By the time this happened, it was too late for any snow accumulations, and we woke up to some snow showers and flurries scattered around our area.
I believe that Cecily Tynan, of 6 ABC, summed up the thoughts of all meteorologists yesterday in her Facebook post about frustrations with forecasting this storm:
"Ok, I am waving the white flag & throwing out any snow maps completely! The track of this storm (more south and moving east , not northeast) is a RAIN and WIND storm, not a snowstorm. It is not out of the question that a few areas could see a BRIEF changeover to snow, but we are quickly running out of time for this to happen. Man, this has been a headache of a storm since last week! Bring on spring. I am done with this frustrating winter!"
If you want to see how tough it was to forecast this storm and visualize the uncertainty among news stations in the northeast, here is a photo that somebody posted of snow total maps on the Rutgers Meteorology Facebook group...

Although snowfall totals busted, the other aspects of this storm that were forecasted came to fruition. Coastal flooding was a big problem along the shore points of NJ, especially from pictures I saw of Wildwood and many other photos that I saw of the ocean making its way up toward the boardwalks of several towns. Furthermore, winds were also a huge issue all across our area, with the most impressive wind gusts naturally coming from the coast. Here are some of the highest wind gusts recorded during the storm:
Harvey Cedars-64mph
Sea Girt-61mph
Atlantic City Marina-60mph
West Cape May-56mph
Philadelphia-46mph

The system will still affect our area today and into tomorrow, as some bands wrap around the low off the coast, bringing some snow and rain showers throughout the day and overnight tonight. Any accumulations would be very light, the best chance for seeing snow on the ground in anyway would be as you head north in New Jersey. The good news, though, is that this weekend is going to be beautiful with plenty of sunshine and highs in the upper 50's!
