The hits just keep on coming...
An active weather pattern will bring two more winter storms to the Mid-Atlantic region between the weekend and the early-to-middle part of next week and there will be multiple other threats to follow. Low pressure will ride up along the Appalachian Mountains late Saturday as a secondary system forms off the Mid-Atlantic coastline. The result will be snow, sleet and freezing rain in the Mid-Atlantic region from Saturday into Saturday night with significant icing in some areas . The bulk of Super Bowl Sunday will be dry with no travel issues expected during the afternoon hours leading up time to the game (starts at 6:30pm). Another storm is likely to take more of a southern track early next week compared to recent systems heading directly to the Mid-Atlantic coastline. This next storm system will bring accumulating snow to the Mid-Atlantic from later Tuesday into Wednesday and perhaps significant amounts in places like the Washington, D.C. metro region.

An active weather pattern will bring three winter storm systems to the Mid-Atlantic region during the next week or so. The first system will bring a mix of precipitation types to the DC-to-Philly-to-NYC corridor from tonight into tomorrow morning and all areas are likely to feature slippery road conditions for the Thursday AM commute. A thin layer of air with slightly above-freezing temperatures will push into the upper part of the atmosphere later tonight from the DC metro region to southeastern PA and this will lead to many hours of sleet and/or freezing rain depending on location. It looks like mainly a snow event in the NYC metro area during the overnight and early morning hours though sleet and rain can mix in at times. All areas along the Mid-Atlantic’s I-95 corridor are likely to experience slippery road conditions for the Thursday AM commute. A similar scenario with mixed precipitation is likely this weekend in the Mid-Atlantic region from late Saturday into early Sunday and there is the potential for accumulating snow during the early-to-middle part of next week as this very active weather pattern continues.

An active weather pattern will likely bring three winter storm systems to the Mid-Atlantic region during the next week or so. The first system will bring a mix of precipitation to the DC-to-Philly-to-NYC corridor from late tomorrow into Thursday morning and all areas are likely to experience slippery road conditions for the Thursday AM commute. A thin layer aloft of slightly above-freezing air will push into the region on Wednesday night, and this will play a big role in precipitation types ranging from snow-to-sleet-to-freezing rain to just plain rain. Always a difficult forecast when dealing with these thin layers, but my initial feeling on this mid-week threat in the I-95 corridor is as follows: DC metro region will get hit hard with freezing rain leading to a significant ice-buildup, the Philly metro region may have an extended period of sleet, and the NYC metro region may actually see snow for much of the event that certainly can mix with sleet at times. A similar weather event could unfold for the upcoming weekend in the Mid-Atlantic region with a “snow-to-sleet-to-freezing rain-to-plain rain” scenario on the table. Looking past the weekend system, there very well may be an accumulating snow threat for much of the Mid-Atlantic region by the middle of next week and it can be significant.

February is now a few days old, and it looks like it will be a very active month with plenty of cold air around and it is likely to feature a polar vortex “split” and high-latitude blocking. There should be plenty of opportunities for snow, ice and rain in the Mid-Atlantic region as we progress through the month with just the next week or so likely to feature as many as three precipitation events. The first opportunity comes at mid-week, and it may turn out to be the first significant icing event in quite awhile for much of the Mid-Atlantic region with possible snow on the front end and plain rain on the back end. A similar scenario may take place this weekend with frozen precipitation possible on the front-end of the next storm system and plain rain on the back end. A third storm may threaten by the middle of next week and this one should have more cold air to work with raising the chance of accumulating snow in the Mid-Atlantic region.

February is now underway and it looks like it will be a very active month with plenty of cold air around and is likely to feature a stratospheric polar vortex split that can impact US temperatures all the way into March. There should be plenty of opportunities for snow, ice and rain in the Mid-Atlantic region and Northeast US as we progress through the new month with just the next week or so likely to feature as many as three precipitation events. Another player on the field that will have to be monitored this month will be the occasional appearance of the Southeast US high pressure ridge – often seen during La Nina winters – and this enhances the possibility of quite warm conditions across the southern states and also chances for severe weather.

February can feature quite active weather across the nation with increasingly warm and humid air down across the southern states and some very cold Arctic air remaining up to the north. In fact, this kind of clash in the atmosphere appears to be setting up for next week which may lead to a storm system that features a wide range of precipitation types at mid-week from rain/thunderstorms in its warm sector to snow and ice in the cold sector. Eventually, it appears the cold air will “win” this battle and overspread the eastern half of the nation in about ten days or so. By the way, Sunday is Groundhog Day and - if I were Phil - I might be apt to see my shadow as it looks like there is plenty of cold air left in the tank for 6 more weeks of winter. Meanwhile, in the short-term, the month of January will end on a wet note in the Mid-Atlantic region with primarily a rain event from late tonight through Friday; however, accumulating snow is likely from interior New York State to New England where at least a few inches are on the table.

Winds will be rather strong for much of today in the Mid-Atlantic region with gusts up to 35 mph or so; however, a more intense and longer-lasting wind event is in store for late tonight and Wednesday associated with the next strong cold frontal system. That next cold front will be trailing a “clipper” low pressure system that passes by to the north on Wednesday, and it can help to generate 50 mph wind gusts from late tonight into late Wednesday. In terms of precipitation, there can be some snow shower/snow squall activity on Wednesday afternoon as this next cold front arrives and, as with today’s frontal system, most of the activity will be limited to the northern Mid-Atlantic.

Bitter cold Arctic air persists across much of the nation with numerous daily low temperature records set across the southern and eastern states. In fact, a few all-time low temperature records were set this morning across southern Louisiana where clear skies, light winds, and a fresh, deep snowpack allowed temperatures to plunge to single digit levels across the region. A rare major winter storm has brought significant accumulating snow across the southern US from Texas-to-Florida-to-the Carolinas and, in some cases, this matched or surpassed the great winter storm of February 1895. The precipitation field associated with this southern storm will push off the southeast coast today, but the bitter cold will persist for a bit longer.

A rare weather event has begun across the Gulf coast that will result in accumulating snow and ice in unusual places such as Houston (TX), New Orleans (LA), Tallahassee (FL), and Myrtle Beach (SC). NOAA has issued “Winter Storm Warnings” all the way from Texas to the Carolinas and - in an unprecedented fashion - even “Blizzard Warnings” have been issued from far eastern Texas to southern Louisiana. In this entire stretch of the southern US, there can be at least a few inches of snow by early Wednesday and an ice glaze may be included in the mix as well in many areas. By this evening, the accumulating snow can make it’s way as far north and east as southeastern Virginia and there can even be a touch of snow along the DC-to-Philly-to-NYC corridor. Arctic air that has enveloped the nation from coast-to-coast is the main contributor to this very wintry and rare weather event for the southern US.

A rare weather event is about to commence across the southern states that will result in accumulating snow and ice to unusual places such as Houston (TX), New Orleans (LA), Tallahassee (FL), and Myrtle Beach (SC). The first three of these cities listed are under “Winter Storm Warnings” and Myrtle Beach is currently under a “Winter Storm Watch”…a very rare event indeed. In this entire stretch, there can be a few inches of snow between tonight and early Wednesday and an ice glaze may be included in the mix as well. Arctic air that has settled all the way down to the Gulf coast is the main contributor to this very wintry and rare weather event for the southern US.
