With very moist profiles and little wind shear, the primary concern for the day was heavy rainfall and localized flash flooding potential with thunderstorms. A flash flood watch was issued for a portion of our region, mainly the higher elevations. Deep warm cloud depths and slow moving storms promoted high rainfall rates. The 00Z sounding noted very high precipitable water values of 1.67 inches, which exceeded the 90th percentile for the date.
