High pressure takes control of the weather today on the back side of a departing cold frontal system and it should result in some sunshine and a breezy, milder afternoon. A weak disturbance slides to our south early tomorrow and then high pressure returns for later tomorrow and Thursday. It’ll be on the cool side on both Wednesday and Thursday and then warmer weather returns for the end of the week and upcoming weekend; however, it’ll become more unsettled as well with an increasing chance of showers. One final note…there should be plenty of sunshine on Thursday for the Nationals home opener against the Phillies and it’ll be a tad cooler-than-normal with afternoon highs in the upper 50’s.

Winds will be quite strong today from a northwesterly direction and can gust to 40 mph or so on the back side of a cold frontal system.

A weak cold front can produce a shower or two on Saturday and it’ll turn somewhat cooler and breezy on Sunday ahead of the next cold front which can produce showers around here on Sunday night and Monday.

An on-going stratospheric warming event that began in late February increases the chance for additional cold air outbreaks as we wind down the month of March from the Great Lakes/Midwest to the Mid-Atlantic/Northeast US. In fact, the typical lag time between a stratospheric warming event over the polar region and its impact on US temperature patterns suggests there may very well be cold air outbreaks to deal with in this part of the country at least until the middle of April. As it turns out, big-league baseball gets underway in earnest in one week’s time on Thursday, March 27th, and the early part of the season may feature plenty of cold weather games thanks in large part to the on-going big-league stratospheric warming event. In addition, the influx of colder-than-normal air masses in coming weeks keeps hope alive across the northern states for those wishing for more snow...yes, even though spring season is now officially underway.

A strong cold front will head this way today from the Ohio Valley and it’ll help to spawn the formation of low pressure near the Mid-Atlantic coastline by later tonight. The combination of the low pressure system and cold front will bring rain to the region from later today into early tonight and winds will kick up as well. In fact, those winds can gust to 40 mph or so by late tonight and through the day on Friday which will be a cooler day compared to today. A weak front can bring some clouds to the area on Saturday and perhaps a shower or two, and then it turns cooler on its heels to close out the upcoming weekend. Another cold frontal system can bring more rain to the area by the early part of next week.

High pressure will control the weather in the Mid-Atlantic region for another day providing us with plenty of sunshine and a very mild afternoon. A strong cold front pushes into the area on Thursday and low pressure will form along the Mid-Atlantic coastline. As a result, a decent rainfall is likely here from later tomorrow into tomorrow night with 0.5” to 1.0” on the table. Colder air will follow the frontal passage to close out the work week with very windy conditions featuring gusts to 50 mph or so.

There will be plenty of cloudiness around early today, but clearing skies this afternoon can allow for temperatures to turn milder compared to Thursday and then they’ll surge later this weekend to very mild levels on Sunday. The weekend will become quite wet, however, with the chance of light rain/drizzle on Saturday and Saturday night, and then occasional rainfall is likely on Sunday. The rain on Sunday can become heavy at times and the winds can be quite strong as a cold front slides eastward towards the coast. In addition, there can be a strong-to-severe thunderstorm or two raising the chance for damaging wind gusts in the Mid-Atlantic region. It turns cooler on Monday following the passage of a cold front, but as is increasingly common for this time of year, the cool down should be short-lived. It should become very mild again in the Mid-Atlantic region by the middle of next week.

Numerous ingredients are coming together for what is likely to be a multi-day severe weather event from the central US to the east coast during the period from later Friday to Sunday night. These ingredients include not just one, but two strong upper-level lows, powerful jet streaks at multiple levels of the atmosphere, an influx of warm, humid air on the storm’s front side, and a surface low pressure system that will deepen to rarely ever seen barometric pressure levels as it moves from the central Plains to the western Great Lakes. All severe weather parameters are on the table during this multi-day event including swaths of intense and damaging winds, strong tornadoes, hail, and torrential rainfall that can result in flash flooding.
