Severe Thunderstorm Warning 23, NWS Huntsville, AL

AREA FORECAST DISCUSSION

245 PM CDT THU MAY 1 2003

RUNNING A BIT BEHIND...LETS GET STARTED.

MCS IS MOVING THIS DIRECTION WITH BROKEN LINE OF SHRA/TSRA EXTENDING
FROM LAND-BETWEEN-THE-LAKES TO AROUND TUNICA MS. OUTFLOW BNDRY FROM
THIS VERY EVIDENT ON 88D...WITH NEW CONVECTION BEING FIRED BY IT.
FIRST PERIOD POPS ARE GOING TO BE BASED ON HOW FAST AND HOW MUCH OF
THIS CONVECTION MAKES IT THIS WAY. SKY COVER WILL BE MOSTLY CLOUDY
FOR AT LEAST THE EVENING HOURS...AND CIRRUS WILL PROBABLY BE AROUND
MOST OF THE NIGHT.

PRECIP WILL CONTINUE INTO FRIDAY...BUT THE MORE I LOOK AT THINGS THE
MORE I AM FEELING LIKE TONIGHT MAY BE THE BULK OF THE PRECIP. WILL
KEEP LIKELY POPS THOUGH...WITH LEFTOVER BOUNDARIES AND OTHER
ASSORTED INFLUENCES...PLUS COPIOUS MOISTURE. WILL HOLD IN CHC POPS
FOR FRIDAY NIGHT WITH FROPA OF THE WEAK FRONT CURRENTLY GETTING
ORGANIZED IN THE PLAINS. WILL TREND MORE TOWARD THE ETA SOLUTION OF
A WEAKER FRONT.

WILL HOLD SATURDAY DRY...ALTHOUGH GIVEN THE ETA SOLUTION I REALLY
COULDNT RULE OUT A SHOWER OR STORM EVEN THEN AS WEAK IMPULSES IN
THE UPPER LEVELS PROPAGATE THROUGH THE AREA. THEN THE FRONT RETURNS
AS A WARM FRONT ON SUNDAY. PREVIOUS FORECASTER ADDED IN POPS FOR
SUNDAY AND THESE POPS ARE LOOKING BETTER AND BETTER WITH EACH MODEL
RUN. RAIN WILL CONTINUE FOR MONDAY AND TUESDAY AS WELL...AND THIS
COULD BE A POTENTIALLY HEAVY RAINFALL EVENT...AS THE NEXT COLD FRONT
IS PROGGED TO STALL OVER THE AREA.

THE GFS FINALLY PUSHES THE FRONT SOUTH OF HERE BY WEDNESDAY...BUT BE
ON THE LOOKOUT...I CAME CLOSE TO ADDING POPS FOR WEDNESDAY...ONLY
DECIDING AGAINST IT AFTER SEEING ISC GRIDS FROM SURROUNDING OFFICES.
WILL LEAVE WEDNESDAY AND THURSDAY DRY AND NEAR CLIMO THIS PACKAGE.

GRIDS AND WEB GFX WILL BE OUT AFTER 3PM...SORRY FOR THE DELAY TODAY.
