Discussion

Winds will continue to be quite noticeable today in the Mid-Atlantic region although they will not be quite as strong as yesterday. Along with those winds, there will be plenty of sunshine and temperatures still on the cool side for this time of year. More tranquil conditions are in store for tomorrow as we close out the work week and it’ll become slightly milder, but there will also be the threat for a few showers. Saturday will be mild, but there is a chance for showers and then it’ll turn breezy and cooler on Sunday following the passage of another cold frontal system. Looking ahead to next week, it looks ugly with a large-scale upper level trough setting up shop in the eastern US and this will bring us the threat for showers over an extended period of time (Tuesday through Thursday) along with cooler-than-normal temperatures.

Discussion

The big weather story of the day will be the strong NW winds that can gust up to 40 mph or so at times. These winds will flood the Mid-Atlantic region with a much cooler air mass compared to yesterday following the passage of a strong cold frontal system late yesterday that brought with it numerous showers and thunderstorms. Temperatures will hold in the 50’s this afternoon despite some sunshine along with those stiff NW winds and low temperatures by early tomorrow morning will once again approach the freezing mark in many areas. It’ll continue on the cool side on Thursday, but milder conditions are likely at the end of the work week and during the beginning of the upcoming weekend before it turns cooler again early next week.

Looking ahead and to put it simply - next week is looking ugly. A large-scale upper level trough will set up shop in the eastern U.S. by the middle-to-latter part of next week and this will lead to an extended period of cool and unsettled weather with the threat for rain over several days. In fact, it'll likely be cold enough later next week in parts of the central/northern Plains and Upper Midwest for some more late season snow to fall in those areas during next week's cool and unsettled weather pattern.

Discussion

Strong high pressure will lose control of our weather today as a cold frontal system pushes towards the east coast. This front will generate afternoon and early evening showers in the Mid-Atlantic region and maybe even a thunderstorm or two. Behind the front, it’ll turn noticeably cooler on Wednesday along with a stiff NW wind and it should remain pretty cool and breezy on Thursday as well. Milder conditions will return to the area as we close out the work week, but so will a threat for showers.

Discussion

Strong high pressure will control our weather to begin the new work week, but a frontal system will approach the Mid-Atlantic region on Tuesday. This next cool front is likely to generate showers later tomorrow and tomorrow night, maybe a thunderstorm or two, and then cooler air will flow into the area on Wednesday riding in on stiff NW winds. Temperatures will remain cool on Thursday and then another frontal system could generate more showers around here at the end of the week.
