Low pressure to our north will produce occasional rain in the area during the morning hours and there can be some clearing skies by the end of the day. After partly cloudy skies tonight, the mid-week looks to be dry and chilly in the DC metro region and then there can be a touch of rain on Thursday, Christmas Day, from another “clipper” system that moves from northwest-to-southeast. A more impactful low pressure is likely here at the end of the week with ice on the table as strong high pressure positioned to our north acts as a source of cold air for the northeastern states.

While the nation’s mid-section enjoys rarely ever-seen sustained warmth for Christmas week, the northeastern states will experience plenty of winter weather during the next 7 days or so. One system will bring some snow and ice to the northern Mid-Atlantic region and Northeast US from late tonight into Tuesday and though not a significant event, there can be some slippery spots tomorrow even in the big cities along the I-95 corridor from Philly-to-Boston. Another storm could threaten the Mid-Atlantic region and Northeast US with accumulating snow and significant ice at the end of the week with strong high pressure positioned over eastern Canada anchoring an Arctic air mass. By the end of the upcoming weekend, another low pressure will slide to the Great Lakes, and its training cold front will head to the east coast. This combination can produce rain, ice and snow across the northeastern states late in the weekend and it’ll be followed by another Arctic air outbreak for the first part of next week.

A cold front passed through the region late Sunday and the new work week will start off on the cold side with sun followed by increasing clouds A “clipper” low pressure system over the Great Lakes will bring thickening clouds to the area by this evening and there can be a bit of late night snow or a mixture of rain, sleet and snow before a changeover to all rain for the morning hours on Tuesday…little to no snow accumulation is expected. Clearing skies on Tuesday night will be followed by a dry, breezy day at mid-week.

A strong cold front will barrel through the region later this morning bringing with it additional heavy rain and maybe even a gusty thunderstorm. Winds will shift from a southwesterly direction this morning to northwesterly for the mid-day and afternoon hours and can gust to 50 mph or so as colder air pushes into the Mid-Atlantic region. Temperatures will drop into the 30’s during the day from the very mild levels in the 50’s reached this morning ahead of the frontal passage. Snow showers are now developing across some of the higher elevation interior locations of the Mid-Atlantic region and a few of these may make their way into the immediate I-95 corridor. The weather will settle down for the weekend with dry conditions expected on both days and a moderate chill in the air.

A strong cold front will barrel through the region early Friday morning, and this system will bring us heavy rain, powerful winds, and maybe even a gusty thunderstorm. Winds will be strong ahead of the front from late tonight into early Friday, gusting up to 45 mph or so from a southwesterly direction, and then they’ll shift to northwesterly following the frontal passage. After a brief lull in the winds immediately surrounding the frontal passage, they’ll pick up markedly during the mid-day and afternoon hours...potentially gusting to 50+ mph. Temperatures will act in a topsy-turvy fashion during the next 24 hours in that they’ll rise into the 50’s later tonight in most areas and then drop sharply into the 30’s during the day on Friday on the heels of the frontal passage. Snow showers are very likely to develop on Friday across some of the higher elevation interior locations and one or two of these can make their way all the way into the I-95 corridor. The weather will settle down for the weekend with dry conditions expected on both days and a moderate chill in the air and another colder-than-normal air mass will arrive for the start of next week.

A strong cold front will barrel through the region early Friday and it will bring us heavy rain, powerful winds, and maybe even a gusty thunderstorm. Winds will be strong late tonight/early Friday ahead of the front and can gust to 45 mph or so from a southwesterly direction. After a brief lull in the winds immediately following the passage of the cold front, they’ll pick up markedly during the mid-day and afternoon hours from a northwesterly direction…potentially gusting to 50 mph or so. Temperatures will act in a topsy-turvy fashion in that they’ll rise into the 50’s later tonight in many places and then drop into the 30’s during the day on Friday following the passage of the strong cold front. Snow showers will develop across some of the higher elevation interior locations on Friday and one or two of these may make their way into the I-95 corridor.

A strong cold front will barrel through the Mid-Atlantic region on Friday morning and this system will be quite active with heavy rainfall and powerful winds from later tomorrow night into Friday. There is even the chance that a squall line of gusty thunderstorms forms right along the frontal boundary zone which could result in downpours and gusty winds right around the Friday AM commute in the I-95 corridor. After a mild start to the day on Friday, temperatures are likely to drop markedly during the mid-day and afternoon hours as the next colder-than-normal air mass pours into the Mid-Atlantic region. Snow showers will develop on Friday across some of the higher elevation interior locations and one or two of these can make their way into the I-95 corridor. The weather will settle down for the weekend with dry conditions expected on both days and a moderate chill in the air.

Temperatures have been below-normal for about twenty days in a row in many spots of the Mid-Atlantic region and the relentless cold pattern that started around Thanksgiving Day is about to come to an end. It turns milder for today and Thursday as high pressure shifts to the east of here and mild conditions will begin the day on Friday just ahead of the passage of a strong cold front. That front will result in a soaking rain event for the Mid-Atlantic region from later tomorrow night into Friday morning and there can be a rumble of thunder as well. The rain will be heavy at times and combined with snowmelt in many areas of the Mid-Atlantic region can produce ponding of water by early Friday so be on the lookout for that to take place. Once the front clears the coast by mid-day Friday, temperatures will drop from the mild levels of the morning, and winds will pick up noticeably from a northwesterly direction…gusting into the 40-50 mph range.

The next big weather event in the Mid-Atlantic region will feature rain associated with a strong cold front and there can even be a thunderstorm in the mix before the frontal system clears the area. The rain can come down hard at times from late Thursday night into Friday morning and - given the current snow cover in much of the area – we’ll have to watch for the possibility of some localized flooding. The strong cold front will pass through the Mid-Atlantic region during Friday morning, and strong winds will develop on its backside from a northwesterly direction gusting to 40 mph or so...even higher wind gusts are likely across New England. In addition, temperatures are likely to drop markedly as the cold air mass pours into the region and snow showers are likely to develop; especially, in some of the higher elevation interior locations. The weather will settle down for the weekend with dry conditions expected on both days and a moderate chill in the air.

Another cold day is in store for the Mid-Atlantic region today as high pressure slowly shifts to our south before weakening and pushing offshore on Wednesday. A warm front will push northward through the area by Thursday and temperatures should reach the low-to-mid 50’s for afternoon highs. An active cold front will slide across the region late Thursday night and rain is likely into the early morning hours on Friday. On the heels of the cold frontal passage, winds will pick up noticeably on Friday and (moderately) colder air will make a return into the northeastern part of the country.
