Hail in Tennessee, August 29, 2007

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
244 PM EDT WED AUG 29 2007

.SHORT TERM...(TONIGHT AND THURSDAY)...SURFACE HIGH WEAKENS AS A
WEAK COOL FRONT APPROACHES THE TENNESSEE VALLEY ON THURSDAY. SHOWER
ACTIVITY WILL BE INCREASING WITH THE APPROACH OF THE
FRONT...HOWEVER THERE ARE SOME MINOR DIFFERENCES ON HOW THE NAM AND
GFS HANDLE THIS PRECIPITATION. FEELING IS THAT BOTH ARE OVERDONE AS
WITH PREVIOUS SYSTEMS AND HAVE UNDERCUT GUIDANCE ON POPS.

IF THE FRONT MOVES THROUGH AS PROJECTED TOMORROW WILL SEE THE FIRST
DAY IN ALMOST A MONTH WITH SUB 90 DEGREE HIGH TEMPERATURES...BUT
THAT IS BY NO MEANS A CERTAINTY.

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)...CENTER OF UPPER
RIDGE RETROGRADES WESTWARD WITH WEAK NORTHWEST FLOW ALOFT. SURFACE
RIDGE ACROSS THE GREAT LAKES AND OHIO VALLEY FRIDAY WILL CONTINUE TO
MOVE EAST TO THE EASTERN SEABOARD THIS WEEKEND ALLOWING DRIER AIR TO
FILTER INTO FORECAST AREA.  SURFACE RIDGING REMAINS OVER THE
SOUTHERN APPALACHIANS THROUGH THE EXTENDED LIMITING CHANCES OF
CONVECTION. DUE TO THE CONTINUED DROUGHT CONDITIONS AND EXTREMELY
DRY SOIL MOISTURE CONDITIONS...DAYTIME INSOLUTION WILL REMAIN MORE
EFFICIENT IN HEATING THE AIR.

LOCAL VERIFICATION SOFTWARE (IVERIFY) CONTINUES TO SHOW THAT MODEL
BIAS REMAINS TOO COOL...SO WILL TREND A DEGREE OR TWO WARMER FOR
MAXIMUM TEMPERATURES THROUGH MOST OF THE EXTENDED.
