Latest Forecast

Behind this morning's cold frontal passage, west-northwesterly winds of 10-20 mph will usher drier and less humid air into northern MD and southeastern PA this afternoon. High temperatures will range from the low 80s along I-81 to the upper 80s in the I-95 corridor under partly-to-mostly sunny skies. A Canadian high pressure system will then settle into the Ohio Valley and eastern Great Lakes region from Wednesday night into Thursday and promote mainly clear skies, light winds and refreshingly cool conditions. Despite the sunshine, high temperatures will be 5-10 degrees below average Thursday afternoon. The area of high pressure will shift into the Commonwealth on Friday, so another mostly sunny and beautiful day is on tap with high temperatures in the low 80s. The weather will be perfect for outdoor activities and sleeping with the windows open at night from Thursday through at least Saturday!
