A double-barreled storm system will impact a large part of the nation from today through Thursday with an initial (primary) low located over the Upper Midwest and a secondary is to form later tomorrow near the Mid-Atlantic coastline. The initial system is producing severe weather today across the Ohio Valley and there are waves of heavy rain running all along the “I-80” states from Illinois-to-Pennsylvania with “flash flood watches and warnings” issued in most areas. The severe weather threat will shift to the east on Wednesday raising the chances for strong-to-severe thunderstorm activity in the southern Mid-Atlantic and eastern Carolinas.
Farther north, it is cold enough for accumulating snow today across portions of Minnesota and Wisconsin and some spots will get dumped on over the next 24 hours. The accumulating snow threat will shift a bit to the east to Michigan by later tonight and perhaps to the south on Wednesday into Iowa and Illinois. Once the secondary storm gets going near the east coast later tomorrow, the accumulating snow threat will shift from the Upper Midwest to the interior Northeast US and some spots in interior New York State and New England will get dumped on by the time Thursday evening rolls around.

An ugly stretch of weather continues in the DC metro region with scattered showers this morning and mid-day and then periods of rain later this afternoon and tonight. Some of the PM rain can be heavy at times and there can be a late day thunderstorm or two. The threat of rain will continue on Wednesday and Wednesday night and the chance for a strong-to-severe thunderstorm will be on the increase. The weather here remains on the cool and unsettled side on Thursday with additional rain showers possible and a shower or two cannot be ruled on Friday as well. Quieter weather finally returns to the metro region this weekend and it’ll turn milder.

An ugly week of weather has begun in the DC metro region with cool conditions and occasional showers today, tonight, tomorrow and Wednesday…some of it can be heavy at times and it doesn’t end there. There will be the chance of a few thunderstorms along the way during the first half of the week and even colder air will push into the area on Wednesday night and Thursday on strong winds and there can be some additional rain shower activity and perhaps even a few snow showers across northern Maryland. This blast of winter-like weather from late Wednesday into Thursday is likely to result in accumulating snow across upstate NY and interior New England - keeping ski season alive and well up there for awhile longer.

Low pressure that has been hanging along the east coast during the past 24 hours or so has pushed out into the open waters of the western Atlantic Ocean and NW winds will kick up here today on its backside. There should be plenty of sunny intervals today with cool conditions and NW winds gusting to 40 mph or so will make it feel even cooler than the actual air temperatures. A disturbance to our west will spread plenty of clouds into the region on Saturday along with some shower activity; however, we should then sneak in a pretty decent Easter Sunday before the weather goes downhill again beginning on Sunday night. Specifically, Easter Sunday is likely to feature partial sunshine and mild conditions with afternoon highs in the mid-to-upper 60’s. By contrast, it’ll turn cooler early next week with the threat of rain from Sunday night into Wednesday.

A stalled-out frontal system along the east coast remains a conduit today for moisture to ride along from south-to-north resulting in occasional light rain or drizzle around here for much of the day. There can be a lingering shower or two this evening and then skies should partially clear in the overnight hours as drier air pushes into the Mid-Atlantic region on NW winds following the departure of low pressure to the western Atlantic. There will be some sunshine on Friday, but it’ll be cool and winds will be rather strong gusting to 40 mph or so from a northwesterly direction. A couple of disturbances can bring some shower activity to the region on Saturday and again Monday, but we may sneak in a pretty decent Easter Sunday with relatively mild conditions and some sunshine.

It is one of the best times of the year when you hear the phrase “Play Ball” and “Opening Day” comes tomorrow in many cities including New York, Philadelphia and Baltimore. Unfortunately, the weather will not cooperate with damp and cool conditions up and down the Atlantic seaboard putting the home openers in serious jeopardy for the Mets, Phillies, and Orioles. Low pressure is to form later today along a stalled-out frontal boundary zone and the result will be occasional rain or drizzle in the DC-Baltimore-to-Philly-to-NYC corridor from later today into tomorrow afternoon. Dry conditions are expected on Friday in each of these cities and with an open day in the schedule, it may be very tempting to simply postpone the openers by one day. If, in fact, these openers are postponed as I do believe they will be then they would quite likely be done so officially as early as this evening.

A cold frontal system will become nearly stationary today along the eastern seaboard and low pressure will form along the boundary zone. This low pressure will head north along the coast and the result here will be an increasing chance of rain today and more rain is likely from tonight into early afternoon on Thursday. On the heels of the low pressure system, winds will pick up on Friday and another chilly air mass will push into the Mid-Atlantic region. A couple of disturbances can bring some shower activity to the Mid-Atlantic region on Saturday and Monday, but we may sneak in a pretty decent Easter Sunday with relatively mild conditions.

High pressure will lose control of the weather around here today as a frontal system approaches from the west. This front will slow down as it reaches the eastern seaboard and low pressure is likely to form along the frontal boundary zone. The result here will be the chance for showers from later tonight into late Wednesday and then perhaps some steadier rain from tomorrow night into Thursday. On the heels of the low pressure system, winds will pick up at the end of the week and another chilly air mass will push into the Mid-Atlantic region.

High pressure to our north expanded into the region on Sunday following the departure of the storm system that produced lots of rainfall around here on Saturday. This high pressure system will control the weather today, but then an approaching frontal system will bring us the chance of showers by mid-week.
On another note, the moon peaked as full earlier today setting the stage for it to reach its new moon phase in two weeks. This next new moon phase will allow for the conditions needed for the solar eclipse on Monday, April 8th, when the moon will be in between the sun and earth and thus block the face of the sun from view.

A heavy rain event is headed to the Mid-Atlantic region as strong low pressure pushes to a position just off the coast by early Saturday. The rain will develop later tonight and continue through much of Saturday, heavy at times, with two to as much as four inches on the table by tomorrow evening… watch for localized flooding. On the backside of the storm, N-NW winds will become very strong from late Saturday into Sunday with gusts to 50 mph possible. Chilly air pushes in for Sunday and persistent winds will make it feel even colder than the actual air temperatures.
