After a dry weekend with high pressure in control, the weather turns much more unsettled this week with multiple chances for rain. A warm front will advance northward through the area later tonight and then a cold front approaches later tomorrow. This combination will increase the chances for some afternoon and evening shower activity on Tuesday and a couple of thunderstorms can mix into the picture. The cold front slides just to the south of here at mid-week and stalls out with low pressure likely to form along its boundary zone. As a result, additional showers are likely here from Wednesday night into Friday with embedded thunderstorms possible as well. The rainfall during the second half of the week could turn out to be a beneficial soaking event.

A cold front will cross the area tonight and pave the way for a dry, comfortably cool weekend in the Mid-Atlantic region. The big player on the field this weekend on the heels of the frontal passage will be a strong high pressure system located over southeastern Canada. This system will produce an onshore flow of air in the Mid-Atlantic region keeping a lid on temperatures as we progress through the weekend. This high pressure will push off the coast early next week opening the door for the chance of showers by Tuesday.

Low pressure that has been near the Mid-Atlantic coastline during the past couple of days will weaken today and push off to our northeast. A cold frontal system will cross the area on Friday and strong high pressure will build into southeastern Canada as we head into the weekend. This high will control the weather in the Mid-Atlantic region for the weekend with comfortably cool conditions and plenty of sunshine on both days.

Coastal low pressure will continue to produce cool, breezy conditions in the region today along with occasional showers and a possible thunderstorm. This system weakens substantially by later tonight and pulls off to the northeast of here allowing for high pressure to our north to resume control of the weather again for the late week and upcoming weekend. After a warm end to the work week on Friday, temperatures will become quite comfortable again on Saturday and Sunday with strong high pressure centered over the southeastern part of Canada.

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 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 late 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.

High pressure to our north will remain in control of the weather around here through much of the upcoming weekend. Both today and Saturday should feature comfortably warm conditions and plenty of sunshine and then the next frontal system will approach the area later Sunday with a possible PM shower or thunderstorm. 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.
