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 teens in some 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 a bit 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 upper teens 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 snow 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 Central Park is 45 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 areas. Overall conditions will improve in the region later in the day as temperatures climb above the freezing mark and they’ll peak near 40 degrees this afternoon. In addition to the lingering freezing rain/rain, winds will be an important factor today gusting up to 25 mph or so. High pressure takes control this weekend with cold conditions on Saturday and less harsh 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 the day, any mixed precipitation is likely to be scattered and on the lighter side in areas to the north of the PA/MD border, but as a stronger low pressure system heads our way this evening, the precipitation shield will expand and intensify across Pennsylvania, New Jersey and southeastern New York. Snow is likely to break out around here in the evening and it could accumulate up to a few inches before a transition to sleet. By late tonight, the sleet is likely to transition to freezing rain and there can be an ice buildup of up to a tenth of an inch in the N/W suburban locations. The Friday AM commute is likely to be an icy mess in the metro region as temperatures hover near the freezing mark.

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.

The current stretch of mild weather will come to a peak today with a breakout of sunshine and temperatures jumping to the upper 60’s. A cold front, however, will push through the region later in the day and this will lead to tumbling temperatures during the overnight hours and set the stage for a wintry weather event from later tomorrow into Friday. During the day on Thursday, there can be a bit of rain, ice and/or snow in the region, but the more widespread and heavier precipitation will begin early tomorrow night and in the form of snow. In fact, the snow can accumulate a few inches before a possible changeover to sleet later in the night. A wintry mix of snow, ice and rain is likely on Friday with an additional small accumulation of snow and ice quite likely and an impact on the Friday AM commute.

Today will be another mild day in the Mid-Atlantic region with periods of rain as low pressure pushes from the Upper Midwest towards the southeastern part of Canada. The current mild stretch will peak on Wednesday afternoon with the breakout of sunshine after a cloudy start and temperatures are quite likely going to reach 65-70 degrees in the DC-to-Philly-to-NYC corridor. The passage of a cold front later tomorrow will then bring about big changes in the temperature department in the overnight hours setting the stage for a winter weather event from later Thursday into early Friday. The winter weather event could include some snow accumulations; primarily, across the northern Mid-Atlantic and a potential significant buildup of ice in places like southern and central Pennsylvania.
