.UPDATE...
FOR 06Z AVIATION.

.DISCUSSION...

THE UPPER LOW CONTINUES TO SIT AND SPIN ALONG THE GULF COAST THIS
EVENING. WITH THE LOSS OF DAYTIME HEATING...MANY OF THE PREVIOUS
SHOWERS AND STORMS HAVE DISSIPATED. HOWEVER...MESOSCALE BOUNDARY
INTERACTIONS WILL CONTINUE TO TRIGGER ISOLATED SHOWERS AND PERHAPS
A STORM THROUGH THE REST OF THE OVERNIGHT PERIOD. MESOSCALE
BOUNDARIES VIEWED ON RADAR ARE QUICKLY PUSHING WESTWARD THROUGH GEORGIA
FROM PREVIOUS CONVECTION. WE`LL HAVE TO WATCH THOSE BOUNDARIES
THROUGH THE NIGHT...AS THEY COULD TRIGGER ADDITIONAL SHOWERS AND
STORMS ONCE THEY ENTER INTO EASTERN ALABAMA AFTER MIDNIGHT.
OTHERWISE...THE FORECAST IS ON TRACK FOR TONIGHT AND MINIMAL
ADJUSTMENTS HAVE BEEN MADE TO OVERNIGHT LOWS. EXPECT SHOWERS AND
STORMS TO INCREASE IN COVERAGE ONCE AGAIN TOMORROW AS THE UPPER
LOW RETROGRADES WESTWARD. UPDATES ARE OUT.

.AVIATION...
06Z TAF DISCUSSION.

A BROAD UPPER LOW SHIFTING WESTWARD ACROSS ALABAMA WILL BRING SCT
SHWRS TO EAST ALABAMA BEFORE 12Z. LCL IFR CIGS HAVE ALREADY FORMED
ACROSS SOUTHEAST ALABAMA AND THE IFR CIGS WILL LIKELY EXPAND EAST
AND NORTHEAST DURING THE OVERNIGHT HOURS. THE IFR CIGS WILL BE
MOSTLY CONFINED TO KMGM AND KTOI... ALTHOUGH THERE IS A SMALL
CHANCE THE IFR CIGS COULD REACH FARTHER NORTH TOWARDS THE I-20
CORRIDOR. SHWRS WILL INCREASE OVER THE REMAINDER OF CENTRAL
ALABAMA AFTER 12Z AS THE UPPER LOW SHIFTS INTO MISSISSIPPI AND
PLACES ALABAMA ON THE MOIST AND MORE UNSTABLE SIDE OF UPPER
SYSTEM. THE MAJORITY OF THE PCPN WILL BE IN THE FORM OF
SHWRS...BUT ISOLD TSTMS POSSIBLE ANYWHERE.
