Severe Thunderstorm Warning 39, NWS Huntsville, AL

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
225 PM CDT MON MAY 24 2010

.DISCUSSION...ANOTHER WARM DAY IS UNDERWAY ACROSS THE TENNESSEE
VALLEY THIS AFTERNOON WITH TEMPERATURES WITHIN A DEGREE OR TWO OF
THE 90-DEGREE MARK. SHOWER AND THUNDERSTORM ACTIVITY HAS BEEN KEPT
TO A MINIMUM ACROSS THE CWA THIS AFTERNOON...BUT SUCH IS NOT THE
CASE FOR AREAS JUST NW OF HERE. CONVECTION HAS BEEN FIRING FOR THE
PAST FEW HOURS ALONG A STAGNANT SURFACE BOUNDARY. SEVERAL INSTANCES
OF HAIL AND WIND DAMAGE HAVE BEEN REPORTED SO FAR THIS AFTERNOON IN
WEST TENNESSEE.

ANY CONVECTION ONGOING LATER THIS AFTERNOON ACROSS OUR CWA WILL
DISSIPATE WITH THE LOSS OF AFTERNOON HEATING AFTER SUNSET. THE NSSL
WRF HAS HANDLED THE CURRENT TRENDS THE BEST AND THEREFORE THE
SHORT-TERM PORTION OF THE FORECAST HAS CLOSELY FOLLOWED THIS OUTPUT.

WITH THE LOW PRESSURE SYSTEM WOBBLING OFF THE COAST OF THE
CAROLINAS...SEVERAL DISTURBANCES WILL AFFECT THE AREA THROUGH THE
END OF THE WEEK. AS A RESULT...TOMORROW...AND PRACTICALLY EVERY
AFTERNOON THIS WEEK WILL BE MUCH OF THE SAME AS TODAY. DIURNAL
HEATING COMBINED WITH THESE DISTURBANCES WILL PRODUCE SHOWERS AND
THUNDERSTORMS ACROSS THE TENNESSEE VALLEY EACH DAY. GIVEN THE STEEP
LAPSE RATES IN PLACE AND THE SOMEWHAT COOLER AIR ALOFT DURING THIS
TIME...DAMAGING WINDS AND HAIL WILL BE THE PRIMARY THREATS WITH ANY
THUNDERSTORMS THAT DEVELOP. PWATS DURING THIS TIME ARE AROUND AN
INCH AND A QUARTER...AND THEREFORE LOCALLY HEAVY RAINFALL WILL BE
POSSIBLE AS WELL.

MOST MODELS ARE IN AGREEMENT WITH THE LOW OFF THE EAST COAST AND A
LOW PRESSURE SYSTEM COMING ASHORE IN THE PACIFIC NW LATE IN THE
WEEK. THE MAIN DIFFERENCE WITHIN THE MODEL OUTPUT FOR LATE IN THE
WEEK IS THAT THE GFS IS ADVERTISING A COLD FRONT PUSHING THROUGH THE
REGION FRIDAY INTO SATURDAY. THE 06Z/12Z ECMWF ALSO SHOW THIS
FRONTAL FEATURE LATE IN THE WEEK...SO WILL ADJUST THE FORECAST
ACCORDINGLY. AM NOT BEING AS ROBUST WITH THE COOLER TEMPERATURES IN
THE WAKE OF THE FRONT LIKE THE GFS SHOWS...BUT EITHER WAY...NEXT
WEEKEND LOOKS TO HAVE MORE SEASONABLE TEMPERATURES ACROSS THE AREA
WITH WEAK RIDGING/NORTHWESTERLY FLOW IN PLACE. AFTERNOON HIGHS WILL
BE IN THE LOWER 80S AND OVERNIGHT LOWS WILL BE IN THE UPPER 50S TO
LOWER 60S.
