Cold weather has become a staple in the area forecast over the past several days, with the only warmup coming during a significant storm system — which produced the first rainfall of over 1″ since September in New York City. Otherwise, though, it has been a cold and dry pattern which has dominated the past several weeks. Some changes are in order during this week, but the start will be characterized by a slight warmup. Monday will be the first of a few “warmer” feeling days, with highs in the 40’s to near 50 in many spots as well as plenty of sun.
During the week, the airmass will slowly modify as a high pressure continues to control the pattern. High temperatures will reach into the upper 40’s and lower 50’s by the middle to second half of the work week. With the warmup, will come a chance of precipitation and the likelihood of clouds, which will move into the area as a warm front moves nears on Thursday.

A dynamic and complex storm system (not a nor’easter by definition despite the efforts of some to call it such) continued to menace the East Coast early on Wednesday, during one of the biggest travel days of the year. Significant delays were reported this morning at several area airports, owing to the strong winds and heavy rain. Through this afternoon, periods of heavy rain are expected to continue. The center of low pressure has moved north and east of the area into Southern New England, but lower pressures extending southward and a noticeable thermal boundary will serve as a “highway” for continuing rainfall.
With time, however, this boundary will shift eastward and the low pressure center will shift north/northeast. The most noticeable effect of this will be the temperature and wind shift. Warm temperatures from earlier this morning (60’s observed throughout much of New Jersey and even into New York City) will become a distant memory as westerly winds behind the aforementioned thermal boundary will usher in colder air. Temperatures are forecast to fall back into the 40’s by later today, and 20’s and 30’s overnight tonight. Snow showers cannot be ruled out by later this evening throughout the area in the wake of the strengthening low pressure center. The heaviest rain is expected to wrap up by mid-afternoon, but will linger into the evening across areas North and East of NYC.

A pre-thanksgiving storm system will create a travel nightmare from Tuesday Night through Wednesday, providing a myriad of threats up and down the east coast. Before we dive into the details of the storm system, what’s causing it to occur, and what you can expect in our area, we can lay out a few things we know as fact as of Tuesday morning. First, there will be significant travel delays on Wednesday. If you’re driving, flying, or using some other form of travel in the Mid-Atlantic or Northeast US, expect delays…likely significant. Second, Thanksgiving day itself won’t be all that bad. So once you make it where you need to be, the weather for actual Turkey Day looks to be fairly pleasant, albeit a bit cold. In our post below, we break down the storm system and what you can expect from it.

What’s the deal, how is this storm forming?
Two pieces of energy in the jet stream across the Central and Eastern United States will phase on Wednesday, essentially very close to our forecast area. A low pressure area will develop from the Southeast States northeastward into New England. As it does so, warm air will stream up the Eastern Seaboard — as will significant amounts of precipitation in association with a strong low level jet and moisture transport. The low pressure system will then rapidly deepen as it moves to our north through New England and into Eastern Canada.
If you thought today was chilly, just wait until tomorrow. The much-advertised Arctic cold front is on its way, which will bring bitterly cold temperatures, and strong northwest winds. There may be a few scattered snow showers or snow flurries associated with this front, especially north and west of the city.
The Arctic front is approaching the region and will be crossing over the next few hours. Temperatures will plummet behind it. Additionally, snow showers can be found, indicated by the blue patches. Any snow showers should primarily remain north and west of the city. Image credit goes to weatherroanoke.com
Any snow showers should primarily remain to the west of the city, given that precipitation tends to dry out once it heads east of the Catskill and Adirondack mountains in a northwest flow. That being said, do not be surprised if a stray snow shower or two does survive a bit further east. Areas in NW Jersey may see a brief period of steady snow covering the ground and reduced visibilities, so any motorists should take caution if they run into this band of snow. Winds will also be gusty, further contributing to any loss in visibility.
Temperatures will drop quickly this evening through the 30s, and our high temperatures tomorrow will actually be occurring at midnight, when temperatures will be in the mid 30s at midnight, and around 30 north and west. They will fall into the upper teens by morning north and west, with wind chills in the single digits, and mid 20s along the coast, with wind chills in the teens. Winds will be sustained between 20-25 miles per hour, with gusts around 35-40 miles per hour. Tomorrow, highs will only be in the upper 20s to lower 30s across the region, as seen in the image below.

Winds will become even stronger tomorrow during the day, with winds sustained between 25 and 30 miles per hour, with gusts as high as 40-50 miles per hour. This will keep wind chills in the teens throughout the entire day. Make sure to bundle up!
