.DISCUSSION...

COLD FRONT IS NOW NEAR THE INTERSTATE 85 CORRIDOR. MOST OF THE
CONVECTION ASSOCIATED WITH THE FRONT HAS STAYED JUST TO OUR EAST
IN N GA. WE DID HAVE SOME STORMS IN OUR FAR SOUTHEAST COUNTIES
EARLIER TODAY WHERE THE PREFRONTAL TROF WAS LOCATED. THE OUTFLOW
FROM THIS PREVIOUS ACTIVITY IS MOVING NORTHWARD TOWARD THE
APPROACHING COLD FRONT. ADDITIONAL ISO/SCT CONVECTION IS POSSIBLE
THRU THE REMAINDER OF THE AFTERNOON AHEAD OF THE FRONT AS IT
CONTINUES TO PUSH SOUTHEAST ACROSS THE FORECAST AREA.

A MUCH NEEDED AND DESERVED DRY PERIOD WILL CONTINUE THRU TUESDAY
NIGHT AS HIGH PRESSURE BUILDS INTO THE SOUTHEAST STATES. LOOK FOR
MOSTLY SUNNY SKIES WITH HIGHS IN THE 70S AND LOWS IN THE
40S/50S...WHICH IS VERY NEAR NORMAL FOR LATE APRIL.

UPPER LEVEL FLOW BECOMES MORE ZONAL MID TO LATE WEEK AND MOISTURE
LEVELS SLOWLY BEGIN TO RISE. SEVERAL WEAK DISTURBANCES WITHIN THE
FLOW WILL SLIDE EASTWARD ACROSS THE DEEP SOUTH LATE IN THE
WEEK AND INTO THE WEEKEND BRINGING SHOWERS AND STORMS BACK TO
CENTRAL ALABAMA...BUT TIMING OF EACH DISTURBANCE IS DIFFICULT TO
PIN DOWN THIS EARLY. THEREFORE HAVE MAINTAINED GENERALLY CHANCE
POPS THRU SATURDAY.
