Talk about some wild weather…
The Mid-Atlantic region will experience some March madness of its own over the next 48 hours or so with record-warmth today along with high winds and late day/evening heavy showers and scattered strong-to-severe thunderstorms and then much colder conditions by mid-week with the chance for accumulating snow. Today’s weather is courtesy of an approaching strong cold frontal system that will pass through the area tonight and set the stage for much colder weather by mid-week. Low pressure will push towards the southern Mid-Atlantic coastline by early Wednesday and it can be cold enough for some accumulating snow in parts of the Mid-Atlantic region. Another impressive cold blast will reach the eastern states early in the upcoming weekend.

Some wild weather in the Mid-Atlantic region during the next few days. There will be unusual warmth today throughout the Mid-Atlantic region with record-breaking highs likely in the DC metro area - all ahead of a strong cold frontal system. In addition, winds will be increasingly strong and gust past 50+ mph later in the day from a southwesterly direction and they’ll remain strong tonight shifting to a northwesterly direction following the passage of a strong cold front. Showers are likely later in the day and this evening and perhaps a strong-to-severe thunderstorm as the front arrives. Much colder air pushes in on Tuesday and Tuesday night and low pressure will head towards the coastline on Wednesday. It can be cold enough at mid-week for snow in parts of the Mid-Atlantic region and some accumulations are on the table….stay tuned.

A strong cold front is pushing through the region this morning and today will turn out noticeably colder than yesterday and overnight lows are liable to be in the low-to-mid 20’s in many suburban locations. After a cold day on Friday, it’ll begin to turn noticeably milder on Saturday and then even warmer for Sunday and Monday. The warm up will likely feature some rain in the Mid-Atlantic region during the second half of the weekend and the early part of next week.

A weak cold front passed through the region last night, but its passage will have little to no impact on temperatures in the region here at mid-week. In fact, it should turn out to be milder today, but then another cold front will push through early tomorrow and it has more of a cold air push behind it. It’ll turn out colder on Thursday following the passage of this next front and temperatures tomorrow night could bottom out in the low-to-mid 20’s in many spots. After a chilly, Friday, it turns much milder by later this weekend and the second half can feature some shower activity.

A weak cold front will push towards our area today with plenty of clouds, but its passage later tonight will have little impact on temperatures for the day on Wednesday. In fact, it should turn out a bit milder tomorrow and then a weak “clipper” system will drop this way on Thursday from northwest-to-southeast and it could produce a shower in the region. It turns colder behind that system to end the work week, but then milder weather returns here this weekend and there can be some shower activity to accompany the warm up.

A cold front passed through the region last night and the new work week will start off quite chilly and well below-normal for the end of February (normal high now at DCA is 51 degrees). A weak cold front will arrive on Tuesday night, but with little impact around here at mid-week in terms of temperatures. After that, a weak “clipper” system with limited moisture will drop from northwest-to-southeast later in the week and a warm front will approach us this weekend raising the chances for some rain in the Mid-Atlantic region.

Roads are mainly just wet early today, but watch for slippery spots as temperatures are still near the freezing mark in many N/W suburbs. Overall conditions will improve in the region later in the morning as temperatures climb above the freezing mark and they’ll peak in the low-to-mid 50’s this afternoon. In addition to some lingering rain today, winds will be an important factor gusting up to 30 mph or so. High pressure takes control this weekend with chilly conditions on Saturday, but milder weather on Sunday. Much colder air will return to the Mid-Atlantic region on Monday following the passage of a cold frontal system at the end of the weekend.

Temperatures tumbled in the overnight hours in the Mid-Atlantic region following the passage of a cold frontal system and setting the stage for a wintry mess from today into early Friday. In fact, temperatures dropped nearly 40 degrees in the I-95 corridor from the lower 70’s on Wednesday afternoon to the lower 30’s by early today as high pressure strengthened into southeastern Canada. From this location, this high pressure system will act as an anchor and a source region for cold air during the next 24 hours – a classic “cold air damming” pattern for the northeastern part of the nation. This kind of an atmospheric setup is setting the stage for mixed precipitation today and an icy buildup later tonight for many in the Mid-Atlantic region and there will likely be an impact on the Friday AM commute.

Much colder air has moved into the Mid-Atlantic region following the passage of a cold frontal system and moisture will head this way in two different waves. During today, some mixed precipitation of rain, sleet and/or snow is likely to break out in the DC metro region as an initial wave of low pressure heads this way. There can actually be a bit of a lull in the precipitation at the end of the day and then a second and stronger wave of low pressure will move in our direction. As a result, freezing rain is on the table for the evening hours and there can be an ice buildup of up to a tenth of an inch in some of the northern and western suburbs. The precipitation will become rather spotty and light in the overnight hours as the heaviest precipitation pushes north of the PA/MD border. Temperatures may hover near the freezing mark early tomorrow with freezing rain still possible in some of the suburbs to the north and west (watch for slippery spots), plain rain is likely by later in the morning and ultimately Friday’s temperatures will peak near 50 degrees.

The passage of a cold front will bring about big changes in temperatures in the Mid-Atlantic region with today’s 60’s plunging to the freezing mark by early tomorrow. This influx of cold, dense air in the overnight hours will set the stage for a wintry mess from later tomorrow into early Friday. Some parts of the Mid-Atlantic will experience accumulating snow at the onset of this winter weather event and other areas will likely end up with a significant ice buildup including across much of southern and central Pennsylvania. The Friday AM commute is likely to an icy mess from the suburbs of Philly to the north and east including in and around the NYC metro region.
