An extreme wind event is in store for the foothills and east-facing mountains today with gusts past 55 mph or so. In fact, the ingredients are there for even higher wind gusts in some spots that can reach hurricane-force levels. Locally strong winds will likely spread into the wind-favored lower elevations later today as well. Another high wind event is in the offing for late Wednesday night and early Thursday morning along the Front Range mountains.

The day dawns with the lowest temperatures of the season so far in the Mid-Atlantic region and, in many spots, it is near or at a record low for the date. After a very cold Tuesday, temperatures will moderate at mid-week as a “clipper” low pressure system pushes well to the north of here resulting in a stiff southwesterly flow of air on Wednesday that’ll bring in slightly milder air. Some precipitation is likely on Wednesday with this initial “clipper” system and - despite the warm up - it may still be cold enough in some areas for a mix of rain and snow at the onset. Another “clipper” system can bring some snow to the area later Friday and then a third one can produce some snow in the Saturday-to-Sunday time frame. That last “clipper” system will usher in another bitter cold Arctic air mass for the late weekend and early part of next week…warmer weather is possible later next week.

The cold pattern that has brought relentless cold in recent days from Alaska to the Mid-Atlantic region will continue for at least another week or so. The new work week begins with some frigid air in the eastern states and overnight lows in the DC-to-Philly-to-NYC corridor will drop to their lowest levels of the season so far. “Clipper” low pressure systems will swing cold fronts through the northeastern states during the next few days limiting any chance for a sustained warmup. One “clipper” can bring rain, ice and/or snow to the Mid-Atlantic/Northeast US at mid-week and a second system can bring a touch of snow in the late week. Over the weekend, low pressure may ride along the Arctic boundary zone, and this system could bring some accumulating snow to the Mid-Atlantic region to go along with the well below-normal temperatures that should last into the early part of next week.

The 2025 hurricane season is winding down across the Northern Hemisphere, and it has been the second straight season with below-normal activity as measured by the metric known as the “Accumulated Cyclone Energy (ACE)”. The most important region when it comes to tropical activity in the Northern Hemisphere is the western half of the Pacific Ocean as it features the highest ACE value of any sector from a climatological point-of view and it was well below-normal for the 2025 tropical season. In the Atlantic Basin, tropical activity ended up slightly above the normal in terms of ACE thanks in large part to the end-of-season blockbuster hurricane named “Melissa” which reached category 5 status and lasted for a lengthy period. However, there were no landfalling hurricanes in the US for the first time since 2015, and the number of hurricanes (5) was below the long-term average of 7.2.

Following a frontal passage, high pressure will build into the region today and funnel in colder air with a northwesterly wind. This same high pressure system will shift to the east of here by mid-week allowing for a southwesterly flow of air to boost temperatures to milder levels.

The week will start off with far below-normal temperatures in the Mid-Atlantic region following the passage of a strong cold front on Sunday night. Temperatures will struggle today to climb past the freezing mark and overnight lows should be in the lower teens in most areas...coldest readings so far this season. Some moderation in temperatures will come by the middle of the week as a low pressure system passes by to our north, and then a “clipper” system could produce some snow and/or rain around here later in the week. Looking ahead, another frigid air mass is likely to impact much of the central and eastern US this weekend supported by an extremely strong Canadian high pressure system.

Low pressure will slide by to our south today and produce accumulating snow across much of central and southern Virginia. In fact, some of the snow can make it as far north as the DC metro region; especially, into those areas on the south and west sides of DC so watch out for possible slick spots and small accumulations later this morning. The week will start off with far below-normal temperatures following the passage of a strong cold front on Sunday night and temperatures later tonight will drop to their lowest levels so far this season. Some moderation in temperatures will come by the middle of the week as a low pressure system passes by to our north, and then a “clipper” system could produce some snow and/or rain around here later in the week.
