.PREV DISCUSSION...
/ISSUED 301 PM CDT SUN APR 26 2015/

A LATE SEASON COOL FRONT WILL PUSH THROUGH CENTRAL ALABAMA
TONIGHT. THE AIR MASS IS TOO DRY TO PRODUCE ANYTHING OTHER THAN
SOME SCATTERED CUMULUS CLOUDS. HIGHS ON MONDAY WILL AVERAGE ABOUT
10 DEGREES COOLER THAN TODAY. AS HAS BEEN THE CASE ALL SPRING...
ALABAMA CAN ONLY MANAGE A DAY OR TWO OF DRY WEATHER BEFORE THE
NEXT RAIN EVENT HITS THE REGION. THE ACTIVE SOUTHERN STREAM WILL
SEND ANOTHER SHORT WAVE TROF INTO THE SOUTHERN PLAINS STATES ON
MONDAY. HIGH LEVEL MOISTURE FROM THIS SYSTEM WILL SEND AN
EXTENSIVE CIRRUS SHIELD ACROSS ALABAMA ON MONDAY. LOW LEVEL
MOISTURE WILL QUICKLY FOLLOW ON TUESDAY AS A GULF LOW FORMS NEAR
THE LOUISIANA COAST. THE MODELS ARE BECOMING MORE AGGRESSIVE WITH
THE ONSET OF RAIN ON TUESDAY...AN RAISED RAIN CHANCES TO LIKELY
FOR MOST AREAS. THIS SYSTEM LOOKS MORE LIKE A LATE WINTER SET-UP
WITH A DEEPENING GULF LOW TRACKING NORTHEAST ACROSS THE FLORIDA
PANHANDLE AND INTO SOUTHERN GEORGIA. THE LOW LEVEL CIRCULATION
WILL LIKELY STAY FAR ENOUGH SOUTH TO KEEP SOUTH CENTRAL ALABAMA IN
A COOL AND MORE STABLE AIR MASS. THE MAY BE SOME ELEVATED STORMS
ON LATE MONDAY NIGHT AND TUESDAY OVER THE SOUTHERN PORTIONS OF
THE AREA AS WARMER AIR ABOVE THE BOUNDARY LAYER PENETRATES INLAND.

MOST OF THE ENERGY AND LIFT FROM THIS SYSTEM SHIFTS INTO GEORGIA ON
WEDNESDAY...AND HIGHER RAIN CHANCES FOR AREAS EAST OF I-65 DUE TO
SOME WRAP-AROUND MOISTURE. THE RAIN SHOULD EXIT EAST ALABAMA
WEDNESDAY NIGHT AS THE DEEPER MOISTURE PULLS OFF TO THE EAST.
COOLER TEMPERATURES AND LOW CLOUDS MAY PERSIST THROUGH THURSDAY
DUE TO STRONG CYCLONIC CIRCULATION ON BACK SIDE OF THE EXITING
TROF. A WARMING TREND HEADING INTO THE WEEKEND WITH NO RAIN
EXPECTED.
