Flash flooding is possible - especially in urbanized and sensitive areas. Discussion...Scattered clusters of thunderstorms continue to persist within an abundantly moist, moderately unstable environment (2+ inch PW, 1000+ J/kg MLCAPE). These storms continue in a marginally sheared environment, with weak westerly steering flow and mergers of multiple, maturing cold pools resulting in several areas of 1-2.5 inch/hr rain rates. FFG thresholds of 2 inch/hr should be exceeded on an isolated to perhaps scattered basis as storms migrate slowly over the next 2-3 hours. Rain rates of approx 1 inch/hr could affect the Birmingham Metro area over the next hour or so, posing an urban flash flood risk. Storms are currently past the peak of the diurnal cycle, with gradually lessening surface-based instability and widespread convective overturning expected to eventually lead to a weakening trend of convection that should gradually lower flash flood threat. This process may take at least 2-4 hours to unfold. Cook ...Please see www.wpc.ncep.noaa.gov for graphic product... ATTN...WFO...BMX...HUN... ATTN...RFC...ALR...ORN...NWC...
