The next cold front will cross the region today and it’ll usher in quite a cold air mass for the upcoming weekend with highs on Saturday and Sunday confined to the lower or middle 30’s. Low pressure is likely to pull out of the south-central states by early Monday and head towards the Tennessee Valley while a secondary system forms off the Mid-Atlantic coastline. Snow is possible here from late Monday into Tuesday and accumulations are on the table, but there are still some questions as to the ultimate northward extent of this early week winter storm.

Philadelphia and New York City received traces of snow early yesterday as an upper-level wave of energy passed overhead, but there has not been anything significant in terms of snow in these two metro regions - nor in the Washington, D.C. area - since the middle of December. This “snow drought” in the DC-to-Philly-to-NYC corridor may come to a rather dramatic end over the next ten days or so. One winter storm can impact the Mid-Atlantic region from later Monday into Tuesday and then a second threat exists for later next week. There have been numerous threats of snow in recent weeks for the I-95 corridor and all have fizzled out, but there is perhaps better cause for optimism this time around for snow lovers in the I-95 corridor.

High pressure pushes into the region today following the passage of a cold front on Wednesday and it’ll remain breezy and chilly. Another cold front will cross the area on Friday and it’ll usher in a colder air mass for the weekend with highs on both weekend days confined to the lower or middle 30’s. Low pressure could bring us some snow and/or ice early next week and accumulations are on the table, but many details will have to be ironed out over the next few days on this upcoming threat.

A strong wave of energy is now crossing over the Mid-Atlantic region and it could produce snow showers in the area and maybe even an isolated heavier snow squall. A colder air mass will pour into the region this afternoon as NW winds increase in intensity with possible gusts to 45 mph or so. It’ll become quite cold by late tonight as the new cold air mass settles into the region and it’ll remain chilly through the remainder of the work week. A reinforcing cold air mass will arrive this weekend – potentially setting the stage for wintry precipitation around here early next week.

This likely should fall in the “Department of Redundancy Department”, but there are snow threats coming to the DC-to-Philly-to-NYC corridor in the near future. A snowstorm in the middle of December that brought accumulating snow to the I-95 corridor has been followed by lots of threats, but no actual snowfall of any significance. While there is a snow shower threat late tonight and early tomorrow, a threat for later in the week that looked promising several days ago appears to have once again fizzled as we approach potential event time. Looking ahead to next week, there are likely not one, but two opportunities for accumulating snow (and ice) in the I-95 corridor and we’ll closely monitor these threats in coming days to see if they actually come to fruition this time around and make snow lovers happy.

High pressure expanded into the region on Monday and it’ll result in another day with dry, breezy and chilly conditions in the Mid-Atlantic region. A couple of weak cold fronts will pass through the region during the second half of the week with reinforcing cold air masses to follow. High pressure will then push back into the region during the upcoming weekend and continue our generally dry and chilly weather pattern in the Mid-Atlantic region.

High pressure builds into the region today and it’ll result in generally dry and chilly conditions along with a noticeable breeze at times. A couple of weak cold fronts will pass through the region during the second half of the week with reinforcing cold air masses to follow. High pressure will push back into the region during the upcoming weekend and continue our generally dry and chilly weather pattern in the Mid-Atlantic region.

A strong cold front will approach the region later today and it’ll tend to slow down as it reaches the eastern seaboard which will allow for the formation of low pressure along the east coast. As a result, showers are possible here by later in the day and occasional rain is likely tonight. It’ll remain unsettled on Saturday behind the front as an upper-level wave of energy passes overhead and there can be some rain and/or snow shower activity in the NYC metro region. Winds will become rather strong in the wake of the frontal passage and should last right through the weekend. Another wave of energy aloft will head this way on Monday and it could generate another shower or two of rain and/or snow.

An energetic stretch of weather is coming to the Mid-Atlantic region with the arrival of a strong cold front on Friday night that will lead to periods of rain and a possible thunderstorm or two. On Saturday, deepening low pressure in the upper atmosphere will pass overhead leading to somewhat unsettled conditions with increasing winds and a possible snow shower or two. The air turns colder on Saturday and the wind will become noticeable out of the northwest and snow showers will be possible at any time. While there will be some sunshine on Sunday, winds will remain quite noticeable and it’ll remain on the chilly side in the Mid-Atlantic region.

High pressure remains in control for another day and then a strong cold front will approach the region late Friday. This front will slow down as it heads towards the eastern seaboard at week’s end and this will allow low pressure to form along the advancing frontal boundary zone. As a result, rain is likely around here early Friday night and, as colder air filters in, there can be some snow and/or rain shower activity late Friday night and at any time on Saturday as a wave of energy moves overhead. Another disturbance can produce a shower or two around here on Monday following a quiet, chilly day on Sunday.
