Latest Forecast

An area of high pressure over southeastern Canada is exerting its influence down the eastern slopes of the Appalachians this afternoon and promoting mostly sunny, dry and pleasantly cool conditions. Yet another, slow-moving storm system will then move into the mid-Atlantic States on Wednesday and stall over the region through the end of the week. As a result, periods of rain will overspread northern MD and southeastern PA later tonight and continue to soak the region on Wednesday. Rain should become lighter and more intermittent Wednesday night into Thursday, but low clouds and drizzle will continue to plague the Lower Susquehanna Valley during this time. Most areas will receive 0.75-1.50" of rain through Thursday. Motorists should be alert for standing water on roadways, as well as flooding of some low-lying, urban- and poor-drainage areas. Due to the clouds and wet weather, high temperatures will be around 20 degrees below normal both tomorrow and Thursday and only in the mid-to-upper 50s.
