.SHORT TERM...TODAY THROUGH THURSDAY.

AN AREA OF MID LEVEL CLOUDS OVER NORTH ALABAMA HAS BEEN SHIFTING
EASTWARD OVERNIGHT AND IT LOOKS LIKE IT WILL BE MOSTLY OUT OF THE
AREA BY SUNRISE. THERE WILL STILL BE SOME LINGERING LOW LEVEL
MOISTURE...SO EXPECT SOME SCATTERED CUMULUS TO FORM DURING THE
DAYTIME HEATING...MAINLY NORTH OF I-20. DESPITE ABUNDANT SUNSHINE
TODAY...NORTHERLY WINDS WILL KEEP HIGH TEMPERATURES SLIGHTLY BELOW
AVERAGE. CLEAR AND COLD TONIGHT AS A SURFACE HIGH BUILDS OVER THE
AREA. LOWERED MINIMUMS TONIGHT DUE TO CLOSE LOCATION OF SURFACE
HIGH. A NICE WARM-UP WEDNESDAY AND THURSDAY AS THE SURFACE HIGH
SHIFTS TO THE EAST OF ALABAMA AND SOUTHERLY FLOW DEVELOPS. A WEAK
COLD FRONT WILL MOVE INTO NORTHWEST ALABAMA LATE THURSDAY
AFTERNOON. MOISTURE WILL BE LIMITED AHEAD OF FRONT...AND WILL
CONTINUE WITH SMALL RAIN CHANCES. THE FRONT WILL CLEAR CENTRAL
ALABAMA BY SUNRISE FRIDAY.

.LONG TERM...FRIDAY THROUGH MONDAY.

POST-FRONTAL COLD AIR ADVECTION WILL KEEP FRIDAYS TEMPERATURES ON
THE CHILLY SIDE...WITH HIGHS SLIGHTLY BELOW AVERAGE. A CUT-OFF
UPPER LOW OVER THE SOUTHWEST STATES WILL HELP PULL PACIFIC
MOISTURE NORTHEAST ACROSS THE SOUTHERN UNITED STATES OVER THE
WEEKEND. MID LEVEL MOISTURE WILL INCREASE ACROSS THE AREA ON
SATURDAY...BUT LOW LEVELS WILL REMAIN DRY AND ANY RAINFALL WILL
LIKELY BE TOO LIGHT TO MEASURE. A NORTHERN STREAM SHORT WAVE TROF
WILL INTERACT WITH THE MOISTURE AND PRODUCE WIDESPREAD SHOWERS
ACROSS CENTRAL ALABAMA SATURDAY NIGHT AND SUNDAY. THE
GFS/ECWMF/CANADIAN MODELS ARE ALL SHOWING RAIN ACROSS ALABAMA ON
SUNDAY...AND RAISED RAIN CHANCES TO LIKELY. THIS SYSTEM WILL PUSH
TO THE EAST OF ALABAMA SUNDAY NIGHT AND RAIN CHANCES WILL DIMINISH
CONSIDERABLY BY SUNRISE MONDAY. A FEW SHOWERS MAY LINGER ACROSS
EAST ALABAMA MONDAY MORNING...BUT MOST AREAS WILL BE RAIN FREE
MONDAY AND MONDAY NIGHT.
