A cool front will slowly work its way through the region today and its proximity can produce afternoon and evening showers and thunderstorms. In fact, some of the PM thunderstorms can be on the strong-to-severe side; especially, in the southern half of the DC metro region with damaging wind gusts and hail on the table. A series of frontal systems and low pressure areas will impact the region during the second half of the week with the threat of showers from time-to-time.

A strong cold front will slide through the region this morning and then a second one late today/early tonight. As a result, the threat of showers will continue around here right into the evening hours and there can be a thunderstorm or two mixed into the picture...any thunderstorm today can generate some small hail. It’ll turn cooler later tonight following the passage of the second front and the weekend will start off on the windy side as high pressure builds into the Mid-Atlantic region. It turns warmer on Sunday and afternoon temperatures can peak in the upper 70’s, but there will be a chance of late day and evening shower activity.

A strong cold front will head in this direction later today and it is going to generate numerous afternoon and evening showers and maybe a strong thunderstorm or two. The threat of rain and thunderstorms will continue on Friday, some of the rain will be heavy at times during the next 36 hours, and any thunderstorm can generate small hail. It’ll turn noticeably cooler later tomorrow night following the passage of the cold front and the weekend will start off on the cool, windy side as high pressure builds into the Mid-Atlantic region. It turns warmer early next week with 75+ degrees possible for highs on Sunday and Monday.

Yesterday turned out to be a very warm day in the Mid-Atlantic region with many areas flirting with the 80 degree mark for afternoon highs. While not quite as warm today, it’ll remain quite mild with temperatures climbing into the middle 70’s this afternoon in the DC area. A strong cold front heads this way later Thursday and this system is likely to generate numerous showers around here and maybe a strong thunderstorm or two from later tomorrow into late Friday. High pressure heads this way for the weekend with slightly cooler conditions on Saturday and then very mild weather for Sunday and Monday.

A mix of sun and clouds today as a warm front advances from southwest-to-northeast across the western Mid-Atlantic region. Looking at the uneclipsed or partially eclipsed Sun through dark sunglasses or any other unapproved filter is a recipe for serious and potentially permanent eye injury (i.e., do not use regular sunglasses).

A large low pressure system that has been plaguing us for the past few days will slowly push away from the Northeast US and the weather in the Mid-Atlantic region will slowly improve during the next few days. It remains breezy and chilly today with the chance for a couple of showers, but likely dry and cool on Saturday, and then dry and milder on Sunday with plenty of sun to close out the weekend. High pressure will be in general control of the weather here during the early part of next week and the warming trend will continue.

Another active weather day is coming to the Mid-Atlantic region with the threat of PM showers, maybe a thunderstorm. Any heavier shower or thunderstorm later today can generate small hail (ice pellets) or graupel (snow pellets) due to a cold upper atmosphere. It stays somewhat unsettled on Friday with lots of clouds and a couple of showers are still possible. Quieter and milder weather returns to the region later in the weekend.

There has been rain, heavy at times, during the past couple of days and there will be rain, heavy at times, during the next couple of days…watch out for localized flooding. There are a couple of differences, however, in overall atmospheric conditions that will have an impact today, tonight and tomorrow. First, the overall atmosphere becomes somewhat more unstable later today leading to an increasing wind compared to earlier in the week and an also an increased chance for a strong-to-severe thunderstorm. In addition, the overall atmosphere will become colder later today and tonight and this will allow for an increased chance of hail (ice pellets) or graupel (snow pellets) during any heavier shower or thunderstorm right through the day on Thursday. The weather remains somewhat unsettled on Friday and it takes until later in the weekend to finally settle down to quieter and milder conditions.

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.
