SHORT TERM /TONIGHT THROUGH THURSDAY/...
NO MAJOR FORECAST ISSUES IN THE SHORT TERM. MAY LIKE PATTERN IN
MID MARCH WILL PERSIST. BROAD UPPER RIDGE WITH WEAK WESTERLIES TO

SVR CONVECTION. COULD SEE ISOLD SHRA/TSRA AS WEAK WARM FRONT FEATURE
ACROSS NRN MS TO SRN GA TRIES TO LIFT NORTH WED BUT SFC FORCING
AND VERTICAL WIND SHEAR WILL BE WEAK. ANY TSRA WILL REMAIN ISOLD
AND BELOW SEVERE LEVELS. HAVE ONLY SLT CHC POPS WED AFTERNOON FOR

MERIDIAN WITH GFS TENDING TO MORE OF A CUTTOFF THAN 12Z ECMWF.
UNTIL THIS TROUGH CAN PROGRESS EAST...AFFECT HERE WILL BE ABOVE
NORMAL TEMPS AND DRY PATTERN. DID NOT MAKE MUCH CHANGES TO FCST.

.AVIATION...
00Z UPDATE...
MAJOR CONCERN FOR AVIATION ARE THE LOW CEILINGS AND VSBYS TOMORROW

EXPECT THE VSBYS TO STAY ABOVE 2SM AT KATL AND 1SM AT OTHER TAF
SITES. WE WILL STILL SEE LIFR CONDITIONS WITH CEILINGS OF 400 FEET
AND MAYBE EVEN LESS. OTHERWISE EXPECT AN IMPROVING TREND TO VFR
CONDITIONS THROUGHOUT THE DAY TOMORROW.

//ATL CONFIDENCE...00Z UPDATE...
MEDIUM CONFIDENCE ON VISIBILITIES AND CEILINGS TOMORROW MORNING.
