Today will start off with some patchy clouds across the area and an afternoon shower or thunderstorm cannot be completely ruled out associated with a departing upper-level feature. High pressure will then push into the area for the mid-week providing us with generally warm and rain-free conditions on both Wednesday and Thursday.

A large trough of low pressure will push into the northeastern states and generate unsettled conditions around here with the likelihood of additional showers and thunderstorms. Some of the rain can be heavy at times, watch for localized flash flooding. The chance of rain will remain on Tuesday, but it won’t be as high as today. High pressure moves into the area at mid-week generating generally warm and rain-free weather conditions.

Weak high pressure will push offshore today and a front will move nearby this weekend with a couple of low pressure systems likely to ride along the boundary zone. As a result, there will be somewhat unsettled conditions this weekend after another mainly sunny and warm day here on Friday. While much of Saturday and Sunday will be rain-free, a shower or thunderstorm is possible from time-to-time.

We have now passed the mid-point of the month of August and, so far, tropical activity has been considerably below-normal in the Atlantic Basin. In fact, activity across the northern hemisphere as a whole has been below-normal as measured by a metric known as the “accumulated cyclone energy” or ACE. There are signs, however, that the lid is about to come off in the Atlantic Basin where a big-time increase in activity is increasingly likely over the next few weeks and beginning as early as this weekend over the Gulf of Mexico.

Temperatures will remain at moderately warm levels today in the Mid-Atlantic region with some sunshine and also the chance of PM showers and thunderstorms. Weak high pressure will take control of the weather on Thursday and it’ll turn a bit warmer as we head towards the upcoming weekend with highs in the 80’s. An upper-level trough of low pressure approaches from the west later in the weekend and that system will bring us a return of unsettled weather conditions.

Low pressure off the Mid-Atlantic coastline will help to keep a low-level flow of air off the ocean over the next couple of days and this, in turn, will help to keep temperatures at manageable levels for the middle of August. High pressure will take control of the weather for the latter part of the week and then conditions become unsettled once again during the latter part of the upcoming weekend.

The first half of the week will be cooler-than-normal in the Mid-Atlantic region with an upper-level trough of low pressure building aloft over the northeastern states. This system could help to spawn the formation of a low pressure over the western Atlantic which would enhance the chance of showers around here into mid-week and also keep a cool low-level flow of air well established. High pressure is likely to take back control later in the week and temperatures will remain on the comfortable side.

A strong cool front passed through the region last night ushering in a refreshing air mass for today and the weekend with comfortable temperatures and humidity levels. In fact, it looks like temperatures will remain at comfortable levels through the first half of next week in the Mid-Atlantic region with high generally in the 70’s. In terms of precipitation, a disturbance over the Great Lakes later this weekend will move in this direction and it can set off some shower activity around here late Sunday night and Monday. This system will help to generate low pressure nearby which can lead to more unsettled conditions on Tuesday and Wednesday to go along with those still comfortable temperatures.
One final note, the Perseid meteor shower peaks later tonight/early tomorrow…there will also be a full (super) moon to contend with in the southern sky.

A strong cool front will sweep through the region tonight and its passage will usher in a refreshing air mass for Friday, Saturday and Sunday with comfortable temperatures and noticeably lower humidity levels. In fact, temperatures should remain at pretty comfortable levels right through the first half of next week. In terms of precipitation, additional showers are likely this morning and a thunderstorm is possible, but the afternoon should feature clearing skies and generally rain-free weather. Late in the weekend, a disturbance over the Great Lakes will drop to the south and east and it can generate some shower activity for the Mid-Atlantic region late Sunday night and/or on Monday.
