Latest Forecast

Southwesterly flow will continue to usher unseasonably warm air into the Lower Susquehanna Valley through the end of the week. A massive ridge, or northward bulge in the Jet Stream, along the Eastern Seaboard will be responsible for the record-breaking heat. Temperatures will approach or reach 90 degrees both Wednesday and Thursday under partly sunny skies. Wednesday's record high temperature of 87 degrees from 1941 at Millersville University will likely be broken, and Thursday's record high of 90 degrees from 2002 may also be tied or broken. A cold front will move through the region Thursday night into Friday but only a brief shower will accompany its passage. In its wake, Friday will turn out partly cloudy and unseasonably warm with highs in the low-to-mid 80s.
