High pressure that had its origin over central Canada will remain in control of the weather around here for another day with comfortably warm conditions, plenty of sunshine, and moderate humidity levels. Two frontal systems will head this way during the next few days with the first likely to generate isolated showers and thunderstorms late tomorrow and tomorrow night and the other brings unsettled weather to the Mid-Atlantic region for Sunday, Monday and possibly Tuesday as well.

High pressure that originated over central Canada will remain in control of the weather around here for the next few days with plenty of sunshine on a daily basis and continuing comfortable temperatures and humidity levels. The next frontal system arrives late in the week, but it looks rather weak and this could be a rain-free event. A stronger system could arrive by the latter part of the weekend and early part of next week with a better chance for some widespread rainfall in the Mid-Atlantic region.

We have now reached rare territory for the Atlantic Basin due to the lack of hurricanes at this stage of the tropical season. In fact, this is the latest time without an Atlantic hurricane during the satellite era which began in 1966 and there is likelihood that one has to go all the way back to 1941 though confidence in the tracking of hurricanes is far less certain in the pre-satellite era. Having said that, an extremely quiet first half of the tropical season does not guarantee an uneventful second half…indeed, there are some signals that activity will pick up later this month.

On the heels of a frontal passage, the first half of the new work week should be quite comfortable in the Mid-Atlantic region with low humidity values. High pressure to our northwest will be in control and today will feature quite breezy conditions with a stiff northerly flow of refreshing air. Another cold front could bring showers to the area late in the week or early in the upcoming weekend.

A frontal boundary zone is hanging nearby this morning and there will be occasional showers and possibly an isolated thunderstorm. A disturbance form the Tennessee Valley will push northeastward into the Mid-Atlantic region this weekend and the result will be additional showers and possible thunderstorms…some of the rain can be heavy. Some improvement is likely later Sunday and the new work week should start with plenty of sunshine on Monday and Tuesday and moderately warm conditions.

A weak cold front will approach the region later today and it can produce showers around here with a possible late day or evening thunderstorm. The front should clear the coast on Friday morning paving the way for a comfortably warm end to the shortened work week and some clearing skies in the afternoon with temperatures reaching the lower 80’s. Another disturbance will arrive this weekend and it can cause showers and thunderstorms in the Mid-Atlantic region from Saturday into Sunday.

High pressure will continue to generate tranquil and warm conditions around here today, but a cold front will head in this direction on Thursday. This next front will raise the chance of showers and thunderstorms later tomorrow and early tomorrow night, but it doesn’t look as widespread of an event as we have experienced in recent days. High pressure should follow the frontal passage for the end of the week with rain-free and warm conditions likely on Friday, but another disturbance can bring us showers and thunderstorms during the upcoming weekend.

Unsettled weather will continue for a bit longer in the DC metro region with another shot at showers and thunderstorms later today and early tonight. The weekend looks to be much quieter as high pressure builds in from our northwest and more comfortable air pushes into the area. Temperatures this weekend will be at or slightly below normal and overall humidity will drop to noticeably more comfortable levels.

After a bit of a break in the high heat on Wednesday, southwesterly flow will push much warmer air back into the region and temperatures should climb to the low-to-mid 90’s. As has been the case in recent days, showers and thunderstorms are forming to our northwest and they’ll drop to the south and east for possible impact during the afternoon and evening hours. Any storm that forms later today can be on the strong-to-severe side with heavy downpours and possible damaging wind gusts. A frontal boundary zone will remain close enough on Friday to keep it unsettled around here with a continuing chance of showers and thunderstorms. A more comfortable air mass should drop southward into the region for part of the Labor Day weekend featuring at or slightly below normal cooler temperatures and lowering humidity values.
One final note…anyone planning to travel to Penn State for their first game on Saturday (@3:30pm) can expect to see mainly sunny skies and high temperatures in the upper 70’s.
