Read the full account →Afternoon thunderstorms were able to form along a boundary left by the passage of a decaying mesoscale convective system during the morning hours of the 27th. Dry air aloft led to the development of sufficient downdraft CAPE, allowing a few instances of localized strong wind.

Read the full account →Several small streams and roads were flooded from heavy rain throughout the county. The flooding was most notable in the northern part of the county. Nashua Road near Nashua was flooded. A few cottages along the Little Neshanock Creek sustained damage from flood waters.
