There will be a brief break in the action today from our recent wet weather pattern with a pretty nice day in store and high pressure building into the region. However, another unsettled and wet period begins late tonight and continues into the upcoming weekend. Low pressure will ride along an approaching cold frontal system on Friday and there can be showers associated with it from late tonight into early Friday. This front will stall to our south by the beginning of the weekend and then turn around and come back north as a warm front. As a result, more rain is likely on Saturday and then as a cold front approaches late in the weekend, additional showers will be possible on Sunday. There is the threat for another storm by the middle of next week which could become quite strong and expansive and potentially have an impact on much of the eastern third of the nation.

The wet weather pattern of recent days continues today as another low pressure system impacts the region with some rain or drizzle and it'll be quite chilly for this time of year. There will be a brief break in the action on Thursday with a pretty nice day in store as high pressure builds into the region, but then another unsettled period begins on Friday. Low pressure will intensify over the middle of the country over the next few days and a frontal system will extend eastward from this low all the way to the Mid-Atlantic region. This frontal system and its associated low pressure will be the focus area for showers around here from Friday through much of the weekend. Looking ahead, there is the threat for another storm by the middle of next week which could be quite strong and potentially have an impact on much of the eastern third of the nation.

Our active weather pattern continues, but there will be a brief break in the action for today and part of tonight. High pressure builds into the region on Tuesday, but another low pressure system will result in more rain for the region from late tonight into Wednesday. The late week is likely to turn unsettled as well after another brief respite in the action on Thursday. A nearly stationary frontal system will extend in a general west-to-east fashion from low pressure in the middle of the country to the Mid-Atlantic region. This stalled out frontal system and its associated low pressure system will be the focus area for showers from Friday well into the weekend.

Multiple storms will track across the country over the next several days bringing significant rainfall to much of the eastern half of the nation, substantial snowfall to higher elevation locations across interior New York State and New England, and severe weather to the Deep South, Tennessee and Ohio Valleys. This active weather pattern is partly the result of continuing cold air outbreaks into the central and eastern US which will very likely persist right into early April. The first storm of a series of upcoming storms is currently bringing heavy rainfall to portions of the Mid-Atlantic region and Northeast US and also accumulating snow to higher elevation interior sections of New York State and New England. A second storm will bring more significant rainfall to the Mid-Atlantic region later Tuesday night into Wednesday and there can be snow on the northern edges of this next storm system. By the end of the week and early weekend, low pressure will intensify over the nation’s midsection and a frontal boundary zone will extend from the low pressure center to the Mid-Atlantic region. The combination of the low and frontal system will produce more unsettled weather conditions on Friday, Saturday and Sunday in much of the eastern half of the nation.

Low pressure tracks northeastward today from the Carolina coastline to the western Atlantic as strong, cold high pressure to our north shifts away from the region. There will be periods of rain today and some of it can come down hard at times. Accumulating snow is likely to fall across upstate PA and NY as well as in the interior sections of New England. High pressure builds in briefly on Tuesday and it’ll turn a bit milder with some sunshine, but this on-going active weather pattern will result in another storm system for late Tuesday night and Wednesday with additional periods of rain.

Unseasonably warm weather on Friday in the Mid-Atlantic region gave way to a much colder weekend following the passage of a strong cold frontal system. The cold air mass in place today across the Mid-Atlantic region and Northeast US is being anchored by a strong, cold high pressure now situated over the southeastern part of Canada. Moisture will advance northeastward later tonight towards the Mid-Atlantic region and our entrenched cold air mass will be reluctant to give up its ground as high pressure slides toward the Canadian Maritimes. As a result, there is the chance for snow or a mix of rain and snow in much of the northern Mid-Atlantic region later tonight into early Monday with significant snow possible across interior, higher elevations of upstate PA, New York and New England.

Unseasonably warm weather dominates the scene today in much of the Mid-Atlantic region with temperatures at mid-day ranging from the 70’s in DC to the 60’s in Philly while stubborn cool air is hanging on in NYC with temperatures in the 50’s. A strong cold front is closing in on the eastern states at this hour and will produce afternoon and evening showers and perhaps a strong-to-severe thunderstorm or two. Following the passage of the strong cold front later tonight, the weekend will become progressively colder as strong high pressure builds into southeastern Canada. By the end of the weekend, moisture will be advancing northeastward towards the Mid-Atlantic region and our entrenched cold air mass will be reluctant to give up its ground as high pressure slides toward the Canadian Maritimes. As a result, there is the chance for some snow or a mix of rain and snow in at least parts of the DC-to-Philly-to-NYC corridor from later Sunday night into early Monday with significant snow possible across interior, higher elevations of the Mid-Atlantic and NE US.

A warm front pushed through the Mid-Atlantic region late yesterday and its passage along with an advancing strong cold front will set the stage for an unseasonably warm end to the work week. Ahead of the strong cold front, winds will pick up noticeably and temperatures will surge through the 70’s. The record high today at Reagan Airport is 83 degrees and it is 77 degrees at Dulles Airport which is well within reach. In addition, showers are likely; especially, during the afternoon and evening hours and there can be a strong-to-severe thunderstorm mixed in as well. Following the cold frontal passage, it’ll turn progressively colder this weekend as strong high pressure builds to our north across southeastern Canada. By the end of the weekend, we’ll have to monitor the progression of moisture from the south-central US. Given the entrenched cold air mass that will be reluctant to retreat, any precipitation that arrives late Sunday night or early Monday could be in the form of snow or a mix of rain and snow in the far northern and western suburbs.

Tomorrow may turn out to be the warmest day so far this season in the Mid-Atlantic region with temperatures soaring to the 70’s in the DC-to-Philly-to-NYC corridor ahead of a strong cold frontal system. In addition, there will be occasional showers; especially, during the afternoon and evening hours and perhaps a strong-to-severe thunderstorm or two mixed in as well. Following the passage of the strong cold front late Friday night, the weekend will become progressively colder as strong high pressure builds into southeastern Canada. By the end of the weekend, moisture will be advancing northeastward towards the Mid-Atlantic region from the Tennessee Valley and our entrenched cold air mass will be reluctant to give up its ground. As a result, there is the chance for some snow or a mix of rain and snow in at least parts of the Mid-Atlantic region early next week and significant snowfall may fall across upstate New York and New England.

A warm front is pushing northward through the region today and its passage tonight will set the stage for an unseasonably warm weather this afternoon and especially on Friday. A strong cold front is going to arrive here tomorrow night and there are likely to be some showers ahead of it and perhaps a strong thunderstorm or two. In addition, the winds will pick up noticeably on Friday and temperatures should soar through the 70’s following the much milder conditions this afternoon. Following the Friday night cold frontal passage, it’ll turn progressively colder this weekend and we’ll have to closely monitor the threat for precipitation by early next week as strong high pressure builds to our north across southeastern Canada. There is the chance that if the precipitation arrives early enough on Sunday night or early Monday, it could begin as snow or a mix of rain and snow given that the entrenched cold air mass will be slow to retreat.
