Flash Flood Warning 10, NWS Huntsville, AL

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HUNTSVILLE AL
852 PM CDT WED APR 19 2006

.UPDATE...
TSTMS STILL ONGOING ACROSS N CENTRAL AND NE AL. SFC LOW PRESSURE
IS CENTERED IN SRN TN WITH AN OLD FRONTAL BNDRY EXTENDING SSE INTO
SW GA. THIS BNDRY IS SUPPORTING THE TSTMS ACROSS N CENTRAL AL
ATTM. BNDRY HAS SLOWED IN ITS WWD PROGRESSION...THUS KEEPING TSTM
DEVELOPMENT OVER N CENTRAL AL THIS EVENING AND THUS FLASH FLOODING
IS BECOMING A PROBLEM ACROSS EXTREME SRN CWA.

DEEP COLD POOL MOVING NW ACROSS THE AREA HAS HELPED TO STABILIZE
THE AIRMASS ACROSS CWA FOR THE NIGHT...WITH THE EXCEPTION OF
CULLMAN COUNTY. SINCE FRONTAL BNDRY IS BECOMING
STATIONARY...EXPECT TSTMS TO PERSIST OVER CULLMAN COUNTY FOR THE
NEXT FEW HOURS AND THUS FLASH FLOODING IS EXPECTED TO PERSIST.
SINCE INSOLATION IS GONE...BELIEVE THE TORNADO THREAT HAS
DIMINISHED GREATLY. ALTHOUGH...SMALLER SCALE BNDRY INTERACTIONS
ARE KEEPING UPDRAFTS STRONG ENOUGH TO SUPPORT HAIL GROWTH.

SO...NOT EXPECTING ANY FURTHER TSTM DEVELOPMENT ACROSS CWA...WITH
EXCEPTION OF CULLMAN COUNTY AND WILL ADJUST POP/WX GRIDS
ACCORDINGLY. SINCE OUTFLOW BNDRY AND TSTMS HAVE BROUGHT INCR CLOUD
COVER TO THE AREA WILL ALSO ADJUST SKY COVER. CLOUD COVER AND
ALSO BUMP MIN TEMPS UP A FEW DEG. TOR WATCH WILL ALSO BE ALLOWED
TO EXPIRE.

.HUN WATCHES/WARNINGS/ADVISORIES...
