High pressure will remain firmly in control across the Mid-Atlantic through the end of the week, bringing several days of dry weather, abundant sunshine, and a gradual warming trend to the Delmarva Peninsula.
After a stretch of comfortable early June weather, temperatures are expected to steadily rise over the coming days as a large area of high pressure builds eastward from the Great Lakes and settles across the Appalachian region. While a developing area of low pressure off the Mid-Atlantic coastline will move northeastward offshore tonight, forecasters expect it to remain far enough away to have little impact on the region.
For Thursday, mostly sunny skies will dominate across Delaware, Maryland’s Eastern Shore, and southern New Jersey. Afternoon temperatures will climb into the lower and middle 80s across inland areas, including Georgetown, Salisbury, and Dover. Communities along the Atlantic coast and Delaware Bay will remain noticeably cooler, generally in the lower 70s, thanks to the influence of chilly ocean waters and developing sea breezes.
As winds shift onshore during the afternoon, some coastal locations may see temperatures drop several degrees compared to inland communities.
Tonight will feature mostly clear skies and mild conditions, with overnight lows falling into the 50s across much of the region.
Looking ahead, the dry pattern shows little sign of changing through Friday and much of Saturday. High pressure is expected to keep storm systems at bay while maintaining plenty of sunshine and low humidity levels. The only exception may be across portions of the Pocono Mountains Saturday afternoon and evening, where a slight chance of an isolated shower or thunderstorm exists.
The biggest weather story heading into the weekend will be the increasing heat. Temperatures are forecast to climb close to 90 degrees on Friday before reaching the upper 80s to lower 90s across much of inland Delmarva on Saturday. Coastal communities will once again remain cooler, with highs generally staying in the 80s due to persistent onshore flow.
The extended stretch of dry weather will provide excellent conditions for outdoor activities, beach trips, and early summer events, though residents should be prepared for increasingly warm afternoons as the weekend approaches.
