A chilly air mass remains in the Mid-Atlantic region for another couple of days and frost will be possible each of the next couple of late nights/early mornings in many suburban locations. High temperatures both today and tomorrow will likely be confined to the lower or middle 50’s which is below normal for this time of year. Milder weather will push back into the region by the end of the week and the weekend will likely remain on the mild side. However, the weekend may not stay completely dry as a system near the east coast could bring showers to the Mid-Atlantic region during the second half…still too early to be certain.

Vigorous upper-level low pressure has pushed into the eastern US and with it some of the chilliest air so far this season. Temperatures today and Wednesday will struggle to escape the lower 50’s for afternoon highs and a frost/freeze is possible during each of the next few late nights/early mornings in suburban locations. Milder weather will return to the Mid-Atlantic by the time we get to the end of the week and upcoming weekend.

Vigorous upper-level low pressure will push into the eastern states over the next 24 hours or so and this will result in some of the chilliest air so far this season to the Mid-Atlantic region and Northeast US. As this system pushes east, atmospheric instability will bring us lots of clouds today and perhaps a few late day showers, maybe a rumble of thunder. The colder air mass filters into the region later tonight from the northwest-to-the-southeast. High temperatures for the next couple of days will likely be confined to the lower 50’s which is colder-than-normal for this time of year and frost will be possible in suburban locations during the late night/early morning time periods of Tuesday/Wednesday/Thursday. Looking ahead, noticeably milder weather will return by week’s end and the upcoming weekend.

A strong cool front passed through the region late yesterday and today will be slightly cooler and a lot quieter. High pressure will build into the area today and it should provide decent weather into the weekend, but then a complex of disturbances will bring about some changes by early next week. The threat of showers will increase again by Sunday night and the coldest air mass of the season should spin its way into the northeastern states for Tuesday and Wednesday of next week. In fact, lake effect snow showers could develop next week for the first time this season in the Great Lakes and Northeast US – perhaps as close as the Poconos in NE PA.

There have been a few chilly air masses that have reached the Mid-Atlantic/Northeast US in recent weeks, but the one destined to arrive here for next Tuesday and Wednesday will likely be the chilliest so far this season. A deep upper-level trough of low pressure will tend to rotate around and intensify during the next few days over the Great Lakes and southern part of Canada and then this system will spin its way into the eastern US by the middle of next week. With lots of instability in the atmosphere and the cold air mass pushing over the still relatively warm of the Great Lakes, snow showers are likely just downstream for the first time this season.

A strong cool front will cross the area later today and it will be accompanied by showers – some of which can be heavy at times – and an afternoon or evening thunderstorm is possible as well with gusty winds. It’ll turn moderately cooler on Friday as high pressure builds into the area. A strong upper-level trough of low pressure should rotate into the northeastern states early next week and it could turn quite a bit chillier here by Tuesday.

High pressure will remain in control of the weather around here for another day and then the most active weather day this week will take place on Thursday with the arrival of a strong cold front. Occasional showers are likely from Thursday into Thursday night, some of the rain can be hard at times, and strong wind gusts are possible. In addition, scattered thunderstorms are possible as the cold front works its way through the region. A cool air mass will follow the frontal passage for Friday and Saturday and then an even colder air mass could rotate into the northeastern states early next week.

High pressure will be in control for the first half of the week with mild temperatures and highs generally in the 60’s. The most active weather day of the week will be Thursday when a strong cold front arrives in the Mid-Atlantic region. This frontal passage later in the week could produce downpours and possible strong wind gusts and cooler air returns for the week’s end and upcoming weekend.

A cold front will pass through the region today without any precipitation; however, it will have an impact on temperatures as it’ll usher in another chilly air mass to the Mid-Atlantic region. After highs in the lower 70’s this afternoon, temperatures will likely be confined to the 50’s on Saturday and the coolest readings so far are possible by early Sunday morning. It stays cool on Sunday to close out the weekend and there should be a mild and quiet start to the new week on Monday and Tuesday.
