Thunderstorm producing Flash Flooding over northeastern PA

9:25 PM

A very slow moving thunderstorm is dropping south through northern Luzerne County this evening and has produced very heavy rainfall over the towns of Harveys Lake, Hallwood, and locations east of Jamison City.  This thunderstorm has been estimated to produce three inches or more over northwestern Luzerne County and will continue to produce heavy rain for at least the next 3 hours.  This thunderstorm will continue to drift south as the cold front pushes south as well.  The thunderstorm will remain a heavy rain producer as the nocturnal low level 850 MB jet stream enhances the moisture advection into the thunderstorms.

UPDATE 9:37 PM:  As this thunderstorm is dropping south towards western Luzerne and eastern Columbia Counties of Pennsylvania, intensification is being observed in the past few minutes.  The core of the thunderstorm is driving towards Benton, PA and should reach Grassmere Park by around 10:04 PM.  This thunderstorm has shown the potential for large hail up to 1.50″, frequent lightning, and continuous heavy rainfall.
