.DISCUSSION...
WARM FRONT HAS PUSHED NORTHWARD AND WAS THROUGH BIRMINGHAM AND
AUBURN. THE NEW AIRMASS IS ACROSS A LARGE PART OF CENTRAL ALABAMA
AND WILL REACH ALL LOCATIONS THROUGH THE AFTERNOON HOURS.
TEMPERATURES HAVE RISEN QUICKLY BEHIND THE WARM FRONT WITH SEVERAL
LOCATIONS SOUTH OF THE FRONT INTO THE LOW AND MID 80S. INCREASED
AFTERNOON HIGHS BY SEVERAL DEGREES ACROSS THE BOARD WITH A FEW
PLACES SOUTHWEST AROUND 90. SINCE MOISTURE HAS INCREASED
SIGNIFICANTLY...TEMPERATURES RISING INTO THE 80S AT ALL LOCATIONS...
AND INSTABILITY...EXPECT SHOWERS AND THUNDERSTORMS TO DEVELOP AS WE
HEAD THROUGH THE AFTERNOON. IN MOST OTHER INSTANCES...THIS ACTIVITY
WOULD GENERALLY BE SCATTERED IN NATURE. BUT DUE TO FORECAST STORM
MOTION UP TO 30 KNOTS...THE SHOWERS AND STORMS THAT DO DEVELOP WILL
MOVE QUICKLY AND COVER SOME GROUND. THEREFORE...INSTALLED LIKELY AT
ALL LOCATIONS...WITH HIGHEST CHANCES SOUTHWEST. A FEW STRONG
STORMS STILL POSSIBLE WEST THIS AFTERNOON...AND MONITOR THE STATE OF
THE INSTABILITY THROUGH THE AFTERNOON. BIGGEST UNCERTAINTY IS A
FOCUSING MECHANISM AS THE WARM FRONT SHOULD PUSH NORTH OF THE AREA.
BUT WIND SHEAR/WINDS ALOFT/INSTABILITY SHOULD BE ENOUGH FOR A FEW
STRONG.

.AVIATION...18Z TAF DISCUSSION.

GUSTY SURFACE WINDS EXISTS AT MOST REPORTING LOCATIONS AS THE
BOUNDARY LAYER HAS MIXED. THEREFORE...WINDS WILL HAVE A SOUTHERLY

LOCATIONS EXCEPT ANB...WITH CUMULUS FIELD LIFTING TO VFR LEVELS.
