It stays mild in the Mid-Atlantic region into the beginning of the weekend, but an Arctic front will slide through the area on Saturday and its passage will bring about much colder conditions for Sunday, Monday and Tuesday. Low pressure is going to form along the Arctic frontal boundary zone by tomorrow night and this system should generate accumulating snow in the Mid-Atlantic region from late Saturday night into Sunday likely on the order of a coating to a few inches in most spots. The core of the Arctic air mass will move overhead by Monday and temperatures on Valentine’s Day will be way below-normal for the middle of February. The Arctic chill wanes by mid-week and then signs point to a big time warm-up by late next week although it is likely to be accompanied by some rain by week’s end.

It stays mild in the Mid-Atlantic region for today and into the beginning of the weekend, but an Arctic front will reach the area tomorrow and its passage will bring about much colder conditions for Sunday, Monday and Tuesday. Low pressure is likely to form along the Arctic frontal boundary zone by tomorrow night and this system should generate some snow in the region from late Saturday night into Sunday. While the odds are against anything significant, snow accumulations of a coating to a couple of inches are on the table later in the weekend. The core of the Arctic air mass will move overhead by Monday and temperatures will be way below-normal for the middle of February. Looking ahead, the Arctic chill will wane by mid-week, and there are signs for a big time warm-up by late next week although it could be accompanied by rain at week’s end.

It stays mild in the Mid-Atlantic region into the beginning of the upcoming weekend, but an Arctic front will reach the area on Saturday and its passage will bring about much colder conditions for Sunday, Monday and Tuesday. Low pressure is likely to form along the Arctic frontal boundary zone by Saturday night and this system could generate some accumulating snowfall in the Mid-Atlantic region from late Saturday night into Sunday. The core of the Arctic blast will move into the region on Monday with temperatures on Valentine’s Day likely to be way below-normal for the middle of February. The Arctic chill wanes by mid-week and then signs point to a big time warm-up by late next week.

The next few days will be relatively quiet in the Mid-Atlantic region and still pretty mild compared to earlier in the week. A weak cold front will pass through the area tonight, but it will have little impact on surface temperatures with another fairly mild day expected on Friday. After a mild beginning to the weekend, an Arctic cold front will head into the eastern states from northwest-to-southeast and it will tend to slow down on its arrival. Snow or rain changing to snow is likely to develop late Saturday night and continue into Sunday morning as a wave of low pressure forms along the cold frontal boundary zone. Much colder air will push into the area on Sunday and it’ll stay quite cold through the early part of next week.

The next few days will be relatively quiet in the Mid-Atlantic region and somewhat milder than recent days. There will be a couple of weak frontal systems to deal with during the next couple of nights, but, in general, high pressure will be the main player as we head into the weekend. It is at this time, the overall pattern becomes much more active. After a mild beginning to the weekend, an Arctic cold front will head into the eastern states from northwest-to-southeast and it will tend to slow down upon its arrival. Snow could actually break out along the slowing-down frontal boundary zone in the Mid-Atlantic region as we head into the second half of the weekend and low pressure will try to intensify off the east coast. A situation that needs to be closely monitored in coming days.

High pressure will remain in control of our weather for the next few days and we’ll turn milder than recent days with some sunshine on each day. A weak cold front will swing through the region tonight and another one on Thursday night, but they will not have much of an impact on temperatures around here. In fact, we’ll turn even milder for the first half of the upcoming weekend. A much stronger cold front is destined to arrive here on Saturday night and it’ll return us to much colder weather conditions for the Sunday/Monday/Tuesday time period. Low pressure will form later this weekend near the east coast and it has a chance to generate some snow in the Mid-Atlantic region in the Sunday/Monday time frame…something to closely monitor next few days.

Low pressure intensified late yesterday as it pushed northeastward just off the Mid-Atlantic coastline and it has now reached the open waters off of eastern New England. On the back side of the low, our skies will clear today and it’ll stay brisk and cold despite the return of sunshine. High pressure will build into the Mid-Atlantic region and be the main player until another cold front arrives later in the week.

Weak low pressure is currently located over the Carolina coastline and it will intensify over the next 6-12 hours as it pushes northeastward. A batch of precipitation well in advance of the low pressure system broke out earlier today in the DC-to-Philly-to-NYC corridor resulting in some patchy freezing drizzle and light snow in spots. A second and more widespread batch of precipitation is now headed northeastward as the low intensifies and it will arrive later today in the same DC-to-Philly-to-NYC corridor with enough residual cold air around to allow for the likelihood of some snow and/or sleet. The threat for some snow, ice and/or rain will continue into the latter part of the evening and small snow/ice accumulations are quite possible; especially, in suburban locations to the north and west of the big cities. Watch out for icy patches on the roads early Tuesday morning as temperatures should be at or below freezing.

Low pressure is organizing just off the east coast today and it will result in some precipitation around here as early as this morning. Temperatures around here this morning are low enough to allow for some patchy freezing drizzle; especially, given the cold ground conditions from the recent chill. Later in the day and this evening, temperatures will be above-freezing; however, there can still be a mix of snow, ice and/or rain. This low pressure system will push away from the area on Tuesday and high pressure will retake control of the weather scene with moderately cold conditions into mid-week.

The slow-moving Arctic front that has been the focus area of significant snow, ice and rain in recent days has crossed through the I-95 corridor region this morning and temperatures have responded accordingly by dropping quickly from very mild early day levels. As a result, plain rain that continues to fall at this time can begin to freeze on some untreated surfaces later in the day and sleet and/or snow can mix in as well by day’s end. Temperatures will continue to drop in the nighttime hours so any still-standing water will certainly freeze as the Arctic air mass arrives in full. Overall impacts of the icing in the immediate I-95 corridor region will be rather limited since drier air will tend to inhibit any appreciable precipitation amounts not long after temperatures drop to the freezing mark or below.
