A clipper system passed by to our north yesterday and low pressure will pass by to our south later today. This system can bring some snow and/or rain to the region this afternoon, but its impact should be rather limited as we’ll be on its northern fringes…little to no snow accumulation expected. It turns milder by the weekend, but a strong cold front passes through on Saturday night ushering in much colder air for Sunday and Monday. We’ll have to watch an active frontal boundary zone early next week for possible low pressure that could produce snow in the Mid-Atlantic region. Looking beyond the early week snow threat, there is a good chance for a noticeable warmup later next week with the 50’s a possibility by week’s end.

An active weather pattern brought a clipper system to the north of the Mid-Atlantic region today with a bit of snow in some areas just in time for the morning commute. Another low-pressure system will take the southern route on Thursday, and some snow and/or rain will be possible in the DC-to-Philly-to-NYC corridor. Another low-pressure system (or two) can impact the Mid-Atlantic region during the early and middle parts of next week and with strong, cold high pressure stationed to the north, frozen precipitation is favored with accumulating snow on the table in some areas.
Looking beyond the early-to-mid week winter weather threats, a noticeable warmup is likely to take place in the Mid-Atlantic region by the end of next week and the warmup can very well last through the second week of March. In fact, temperatures could climb into the 60’s by late next week in portions of the southern Mid-Atlantic region (e.g., Washington, D.C.) and the 50’s are possible in the northern Mid-Atlantic (e.g., Philly, NYC) and it could turn even milder than that during the second week of March. This potential warmup may not be the end of the colder-than-normal weather; however, as there are strong signs for another significant stratospheric warming event to take place by late next week. This potential polar vortex split can bring a return of colder-than-normal weather conditions to the eastern states from around the middle of March to the middle of April.

A clipper system is passing by to our north and it is producing a bit of snow and small accumulations in the area early today, but it turns milder this afternoon with the return of some sunshine. Another low pressure system will push to our south on Thursday and it can generate some snow here or a mix of snow and rain. Dry weather is likely to follow for Friday and Saturday, but more low pressure systems can impact the region early-to-mid next week as this active pattern continues.

An unsettled weather pattern continues this week with a couple of systems to deal with in the Mid-Atlantic region during the next few days. A clipper system will drop south and east across the Great Lakes region and it can produce some snow around here late tonight into early Wednesday. While accumulations should be on the small side, the timing is not great as it can interfere with the early morning commute. Yet another system will take a different track on Thursday and move in this direction from the Tennessee Valley and it can produce some snow, ice and/or rain from later Thursday into Thursday night.

Intense low pressure will only slowly pull away from the Mid-Atlantic region on Monday leading to more snow around here this morning, a continuation of the strong winds, and some additional accumulations are likely. Temperatures will be well below normal for the next few days as a much colder-than-normal air mass will flood the eastern states on the heels of the storm. The overall pattern remains quite active with some snow possible late tomorrow night/early Wednesday as a clipper system passes by to our north.

What may become known as the “Blizzard of 2026” to many in the eastern Mid-Atlantic region begins rather innocuously this morning with plain rain and above freezing temperatures in some areas and a mixture of rain and snow is likely soon in other locations. However, precipitation will change over to all snow by later in the day in most areas, become heavy at times early tonight, and continue into mid-day Monday – a long duration event. In fact, the snow could fall heavy enough tonight in the eastern Mid-Atlantic region to produce 2+ inches per hour and “thundersnow” is on the table. Snowfall amounts in the eastern Mid-Atlantic will become significant with a foot or more in many areas. The DC metro region will escape the significant snowfall amounts coming to the eastern Mid-Atlantic, but at least a few inches are on the table in the nation’s capital. Winds will become a big factor by later tonight and continue strong on Monday resulting in blowing and drifting of snow during the latter stages of the storm. On the heels of the storm, a very cold air mass will flood the eastern US for the first half of the new week.

Major winter storm to slam much of the Mid-Atlantic region…
All-out blizzard conditions in many areas…
Low pressure will intensify rapidly later tomorrow as it pushes slowly northward just off the Mid-Atlantic coastline, and it is going to produce substantial snowfall in some areas and powerful winds as well especially along coastal sections. The precipitation in the DC-to-Philly-to-NYC corridor will begin on Sunday morning as plain rain in some areas, a mixture of rain and snow in others, but all areas will feature a changeover to snow by later Sunday. The snow is likely to fall heavily at times from Sunday evening into mid-day Monday, leading to big-time travel disruptions for the Monday commutes in many areas. On the heels of the storm, a very cold air mass will flood much of the eastern US during the early part of next week.

A significant snowstorm for the DC-to-Philly-to-NYC corridor…
Low pressure will intensify rapidly later Sunday over the western Atlantic Ocean, and it is very likely to produce accumulating snow in the DC-to-Philly-to-NYC corridor with significant amounts of 6-12+ inches on the table. The precipitation may begin as rain or a mix of rain and snow on Sunday morning/midday before changing to all snow by later in the day and the snow can come down heavily at times from late Sunday into Monday morning…potentially leading to big-time travel disruptions for the Monday morning commute. The storm will intensify rapidly as upper-level support takes on a “negative tilt” and enhances upward motion at surface levels in the Mid-Atlantic region. The possibility of a significant snow event in the Mid-Atlantic’s I-95 corridor will largely depend on the ultimate track of the storm with a “hugging” of the coast more favorable for highest accumulation amounts…this scenario is looking increasingly likely. Farther up the I-95 corridor, a significant snowstorm is also quite likely across southern and eastern New England including the Boston metro. On the heels of the storm, a very cold air mass will flood much of the eastern US during the early part of next week.

It remains quite unsettled around here today with a frontal boundary zone in close proximity. There will be periods of rain into the mid-day hours, some of the rain can be heavy, and temperatures hold on the cool side with a low-level ocean flow of air. The weekend will begin with some clearing skies on Saturday and relatively mild conditions. By early Sunday, all eyes will begin to focus on the Carolina coastline where low pressure will begin to develop. This system will head to the open waters of the western Atlantic Ocean and rapid intensification is likely to take place. Precipitation is likely to break out as rain on Sunday along much of the DC-to-Philly-to-NYC corridor, but a changeover to snow should occur later in the day. Snow is likely to fall on Sunday night…possibly heavy at times…and it could last into Monday morning potentially causing problems for the morning commute. Some accumulations are very likely in the I-95 corridor and there is the potential for a significant snow event depending on the ultimate track of the storm. A very cold air mass for this time of year will flood the eastern states early next week in the wake of the storm system…stay tuned.
