Latest Forecast

A Canadian high pressure system over the Northeast will promote mostly cloudy and unseasonably cold conditions today with high temperatures around 10 degrees below normal. A warm front will lift northward through the Commonwealth later tonight through Tuesday and bring a light wintry mix of snow, sleet and freezing rain to the Lower Susquehanna Valley between 1-10 AM. Most areas will receive a coating to 1" of snow and sleet and a light glaze of ice prior to a changeover to plain rain during the mid-to-late morning hours. Untreated and secondary roadways may turn slick and slippery, so motorists should exercise extra caution during the morning commute. Periods of light rain will then persist into Tuesday night before tapering off early Wednesday morning. The frontal boundary will still be over or in close proximity to northern MD and southeastern PA on Wednesday. As a result, clouds will linger throughout the day, and an additional shower or two cannot be ruled out. However, temperatures will be significantly higher than Tuesday and reach the low-to-mid 50s in most spots.
