AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
400 PM EDT TUE JUL 11 2000

MODELS IN GOOD AGREEMENT WITH OVERALL PATTERN...BUT DIFFER ON AMOUNT
AND LOCATION OF PRECIP. ETA AGAIN IS THE DRIEST MODEL...BUT MY
PREFERENCE IS THE NGM. UPPER RIDGE CONTINUES TO BUILD OVER CENTRAL
ROCKIES AS HEIGHTS FALL IN EASTERN U.S. IN RESPONSE TO SHORT WAVES
SLIDING DOWN EAST SIDE OF RIDGE. THIS AFTERNOON'S CONVECTION HAS
SEEMED TO DEVELOP ALONG 850 MB THETA-E AXIS FROM N CENTRAL TO SW GA
AS SEEN ON RUC AND MESO-ETA. CELLS HAVE PULSED AND HAVE PRODUCED
MINIMAL SEVERE WINDS AND HAIL. FOLLOWING THETA-E PATTERN WOULD SEEM
TO LEAD TO ACTIVITY DIMINISHING AFTER LOSS OF DAYTIME HEAT...
ESPECIALLY OVER WEST PART OF STATE.

LOOKING AT IR SATELLITE COMPLEX OVER EASTERN KENTUCKY HAS DEVELOPED
IN AREA OF DIVERGENCE NEAR FRONTAL BOUNDARY. WOULD EXPECT THIS COMPLEX TO
SLIDE SOUTHEAST OVER MOUNTAINS. IN THE ANTICYCLONIC PART OF THE
STRETCHING OVER TENNESSEE...WOULD EXPECT LESS ACTIVITY. AT THE
SURFACE THE FRONT IS PROGGED TO BACKDOOR NORTHEAST GEORGIA EARLY
THURSDAY MORNING. WITH FRONT IN AREA CAN SEE POSSIBILITY OF PRECIP
CONTINUING INTO LATE WEDNESDAY NITE OR THURSDAY MORNING BEFORE
DIMINISHING.

WILL USE BLEND OF FWC/FAN POPS FOR MOST PART...AND WILL TAILOR
TONITE'S POPS TO LATE LOOK AT RADAR. FWC/FAN TEMPS SIMILAR BUT WILL
STAY A LITTLE CLOSER TO FWC.
