Jul 2, 2013
A very warm and humid air mass was in place over the region on the 2nd of July. Precipitable water values approaching 2 inches were common across the forecast area. Thunderstorms which formed on this day produced very heavy rainfall of 2 to 4 inches in less than 3 hours over already saturated ground. This resulted in the destruction of many roads and the flooding of apartments and residences in both Sullivan and Grafton counties.
