A strong cold front will sweep across the Mid-Atlantic region later today and its arrival could result in strong-to-severe thunderstorm activity. Ingredients are coming together for this potential PM severe weather including high humidity levels, a vigorous wave aloft, and the strong surface cold front. Following the passage of the front, it’ll turn cooler late tonight and the next couple of days will be quite comfortable with lower humidity and plenty of sunshine on both Tuesday and Wednesday.

Moisture associated with an ocean storm that has retrograded back to the east coast will push northward today into the Mid-Atlantic region and it sticks around through the upcoming weekend. Showers can occur at just about any time today, tonight, tomorrow and on Sunday, but much of the time will be rain-free. In addition to the shower threat, a thunderstorm or two can be mixed into the picture during each of the next few days and – for the first time this spring season – humidity will become a noticeable factor. An incoming cold frontal system will extend the unsettled weather conditions around here on Sunday night and Monday and this timing could be a negative for the viewability of the total lunar eclipse on Sunday night. Better weather returns to the Mid-Atlantic region for Tuesday and Wednesday following the early week passage of the cold front.

High pressure stationed to our northeast will control the weather around here for another day, but the pattern becomes more unsettled by later tonight and tomorrow. Moisture associated with the same low pressure system that dampened our last weekend will ride up along the eastern seaboard over the next 24 hours or so resulting in unsettled weather conditions here right through the upcoming weekend. Not only can a shower take place at just about anytime on Friday, Saturday and Sunday, but a thunderstorm or two can be mixed in as well and humidity will become a noticeable factor for the first time this season. A frontal system will bring the chance for additional showers on Sunday night and Monday - perhaps diminishing our chances for viewing a total lunar eclipse.

High pressure stationed to our northeast will remain in control of the weather around here for the next couple of days, but it will also act to push an oceanic low pressure system back to the Southeast US coastline later in the week. This is the same system that dampened much of the past weekend in the Mid-Atlantic region and its moisture field will move northward along the eastern seaboard at the end of the week. As a result, the chance of showers will increase here on Thursday night and Friday and - for the first time this season - humidity will become a noticeable factor. The threat for scattered showers will continue on Saturday and Sunday as well and temperatures will stay on the warm side with daily highs in the 70’s.

Overall weather conditions improved markedly on Monday in the Mid-Atlantic region and it should stay quite nice through at least the day on Thursday with plenty of sunshine each day and comfortable temperatures. High pressure stationed to our northeast will remain in control for the next few days, but it will also act to push an oceanic low pressure system back to the east coast later in the week. This is the same storm system that dampened much of the weekend in the Mid-Atlantic as it interacts with a northern stream wave of energy, its moisture could push northward along the eastern seaboard by the early part of the weekend. The result is likely to be an increasing threat of showers by the time we get to Friday night and Saturday although temperatures should remain on the warm side.

After a miserable last few days of chilly, windy and damp weather, conditions will improve markedly today, and the bulk of the week looks to be pretty decent. High pressure to our north will produce some sunshine here today and it’ll turn milder with afternoon highs in the 60’s. Stalled-out low pressure over the western Atlantic Ocean will be forced back to the west later this week and its moisture field could impact our weather by the early part of the upcoming weekend.

A soaking rain event is coming to the Mid-Atlantic region for today, tonight, and tomorrow and it’ll become quite cool and windy as well. Intensifying low pressure will cross over the Ohio Valley later today and then as it reaches the east coast, it will begin to become influenced by building high pressure over southeastern Canada. As such, the low pressure will slow down in its advance to the east and ultimately will stall-out over the western Atlantic Ocean. The “blocking” type upper air weather pattern that sets up could prolong the chilly, damp weather in parts of the Mid-Atlantic region on early Sunday, Mother’s Day; especially, along coastal sections.

A soaking rain event is coming to the Mid-Atlantic region for Friday and Saturday and it’ll become quite cool and windy as well. Intensifying low pressure will cross over the Ohio Valley on Friday and then as it arrives the eastern US, it will begin to become influenced by building high pressure over southeastern Canada. As such, the low pressure will slow down in its advance to the east and ultimately will stall-out over the western Atlantic. The “blocking” type pattern that sets up in the upper atmosphere could prolong the chilly, damp weather into Sunday, Mother’s Day; especially, along coastal sections of the Mid-Atlantic. Later next week, the strong block will likely result in a retrogression of the stalled-out low pressure system and it likely moves from east-to-west and back to the east coast perhaps classified as a “sub-tropical” system.

A soaking rain event is coming to the Mid-Atlantic region for Friday and Saturday. High pressure will move back into the region today, but its stay will be rather short-lived. Another low pressure system will head across the Ohio Valley on Friday and bring us rain here from tomorrow into Saturday and it’ll turn cooler and as well. Some of the rain during this event can fall heavily at times and winds will get quite gusty on Friday night and Saturday. After that, this same low pressure system will stall just off the east coast at the same time strong high pressure builds to our northeast over southeastern Canada. There will be a battle on Sunday, Mother’s Day, between the nearby low and high pressure systems with cool, breezy conditions quite likely as well as the chance for showers; especially, in eastern sections of the Mid-Atlantic region.

An active weather pattern continues across the nation and the overall situation in the upper part of the atmosphere will take on a different twist later this weekend and next week. One of the reasons this pattern has been so active has been an on-going onslaught of colder-than-normal air masses from Canada into the US which adds to the possibility of severe weather outbreaks. One area of concern later today and tonight for the possibility of severe weather is the southern Plains with a focus of attention on Oklahoma and northern Texas. This “enhanced” severe weather threat will shift slightly to the east on Thursday. Looking ahead, very strong high pressure ridging will develop over southeastern Canada later this weekend and into next week and this setup could actually help to push an offshore stalled-out low pressure system back towards the west and to the east coast sometime later next week.
