The week started with high pressure to our north in control of the weather in the Mid-Atlantic region, but changes are on the way. Low pressure near the Carolina coastline has intensified during the past 24 hours and it has a good chance of producing showers around here from later today into Wednesday. It will also become quite breezy and an onshore flow of air will keep it unseasonably cool for the next couple of days. The heaviest rainfall and strongest winds associated with this coastal low pressure system will extend from from southeastern Virginia to the southern half of the Delmarva Peninsula to southern New Jersey. High pressure will then follow on its heels for the latter part of the week bringing us more in the way of warm and dry weather conditions.

High pressure to our north will be in control of the weather to start the work week providing us with warm conditions and some sunshine. Low pressure is strengthening just off the Carolina coast and it has a good chance of pushing to the north and west over the next 48 hours resulting in shower activity around here from later tomorrow into Wednesday. It will also become quite breezy and an onshore flow of air will keep it unusually cool for the mid-week. The heaviest rainfall and strongest winds associated with this coastal low pressure system will likely extend from from southeastern Virginia to the southern half of the Delmarva Peninsula to southern New Jersey. High pressure will follow on its heels for the latter part of the week bringing us more in the way of warm and dry weather conditions.

After a surprise (and welcome) heavy rain shower late Thursday in some parts of the metro region, the work week should end with comfortably warm conditions and plenty of sunshine. High pressure controls the weather for the next couple of days and then a frontal system will approach late on Sunday. High pressure builds to our north once again on Monday and then we’ll have to watch for another possible low pressure system to develop just off the east coast that could bring some showers here by mid-week.

Low pressure is pushing away from the coast today and high pressure to our north will take control of the weather in the Mid-Atlantic region as we head into the weekend. Temperatures will remain in a comfortable zone during the next few days with afternoon highs generally near the 80 degree mark. A cold front heads this way late Sunday/Sunday night and it could cause some shower activity in the area before another high pressure edges in early next week.

The Atlantic Basin tropical season officially extends from June 1st to November 30th, and the climatological peak is right around the 10th of September. This year is quite unusual in that the climatological peak comes with no tropical activity whatsoever in the Atlantic Basin and the overall season is now below normal for this time of year. In fact, global activity across the entire northern hemisphere is below-normal and that breaks down to each of the oceans being quieter-than-normal (Atlantic, Pacific, Indian). One of the possible explanations for the relatively quiet tropical season across the globe is the dramatic cool down in sea surface temperatures from a year ago. Looking ahead, there is another half of the season to go for the Atlantic Basin - at least in terms of climatology - and signs point to a pickup in activity potentially beginning as soon as this weekend.

Low pressure that has been hanging around the east coast in recent days will push a bit to the north and west today and the result here will be plenty of clouds, an ocean flow of unseasonably cool air, and occasional showers or drizzle. This system pushes away by later tonight and Thursday will turn out noticeably warmer with plenty of sunshine. High pressure to our north takes control of the weather for the latter part of the week and probably provides protection for us in the Mid-Atlantic region right through the upcoming weekend.

High pressure remains in control of the weather in the Mid-Atlantic region for another day providing us with plenty of sunshine and pleasant conditions. By early tomorrow, low pressure along the coast is likely to come close enough to throw plenty of clouds our way and there is the chance of showers in the eastern Mid-Atlantic region; especially, across New Jersey and the Delmarva Peninsula. High pressure should resume control of our weather for the late week and likely stay in control through most of the upcoming weekend.

A strong cold front pushed off the east coast on Sunday and paved the way for comfortably cool conditions through much of the week. High pressure will be in control of the weather in the Mid-Atlantic region for the next couple of days providing us with plenty of sunshine. At mid-week, low pressure along the coast may come close enough to throw some clouds our way…perhaps even a few showers; especially, across coastal New Jersey and the Delmarva Peninsula. High pressure should resume control of our weather for the late week and likely the upcoming weekend.

Our dry spell ended last night with the arrival of a cold frontal system and scattered showers and thunderstorms. An even stronger cold front will arrive later tomorrow bringing with it another round of showers and thunderstorms for the Mid-Atlantic region. Following its passage, a much cooler-than-normal air mass will push east on Sunday into the Mid-Atlantic region from the Great Lakes and comfortably cool conditions will prevail for the early part of next week.

The rain-free weather that we’ve experienced during the past several days should come to an end later today with the arrival of a cold frontal system. Though the front is weakening as it heads towards the east coast, it should still be able to produce some shower and thunderstorm activity around here from later today into early Friday breaking our current dry spell. In fact, a few strong storms are possible which can contain brief downpours. A second cold front will arrive late Saturday and it too can produce some shower and thunderstorm activity in the DC-to-Philly-to-NYC corridor. High pressure will return to the area for the Sunday and Monday time frame and another cool and dry air mass will spread here from the Great Lakes.
