AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
248 PM CDT SUN MAY 24 2015

.DISCUSSION...

HUMID CONDITIONS HAVE RETURNED TO CENTRAL ALABAMA WITH DEWPOINTS IN
THE 60S AND 70S ACROSS THE STATE. CURRENT WATER VAPOR IMAGERY AND
RAP UPPER AIR ANALYSIS INDICATES A LONGWAVE RIDGE TO THE EAST
CENTERED ACROSS THE FLORIDA PENINSULA WITH A CLOSED LOW TO THE WEST
ACROSS THE ROCKY MOUNTAIN REGION. A SHORTWAVE TROUGH CAN BE NOTED
MOVING ACROSS THE LOWER MISSISSIPPI RIVER VALLEY AND THIS HAS SET
OFF A FEW SHOWERS AND STORMS ACROSS SOUTHWESTERN PORTIONS OF CENTRAL
ALABAMA EARLY THIS AFTERNOON. LOOKING AT SATELLITE ESTIMATED PW
VALUES HAVE ALREADY INCREASED TO OVER 1.5 INCHES IN THIS AREA AND
EXPECT CONVECTION WILL CONTINUE TO PROGRESS TO THE NORTH OVER THE
NEXT FEW HOURS. LOOKING AT THE MESOANALYSIS...SBCAPE VALUES ARE OVER
2000 J/KG ACROSS SOUTHWESTERN PORTIONS OF CENTRAL ALABAMA BUT DEEP
LAYER SHEAR VALUES ARE ONLY AROUND 15-20 KTS. THEREFORE...THERE
COULD BE A FEW STORMS PULSE UP TO PRODUCE WIND GUSTS AROUND 40 MPH
BUT STORMS WILL REMAIN BELOW SEVERE LIMITS. CONVECTION IS MOSTLY
DIURNALLY DRIVEN AND EXPECT ACTIVITY WILL DECREASE IN COVERAGE AND
INTENSITY AFTER SUNSET. THERE IS STILL SOME QUESTION AS TO HOW MUCH
ACTIVITY WILL CONTINUE INTO THE OVERNIGHT PERIOD WITH THE SHORTWAVE
TROUGH APPROACHING...THERE WILL BE SOME SYNOPTIC LIFT THAT COULD
KEEP COVERAGE GOING A BIT MORE THAN A TYPICAL SUMMERTIME SETUP
WITH BEST CHANCES ACROSS WESTERN PORTIONS OF CENTRAL ALABAMA.

ANOTHER UPPER LEVEL TROUGH WILL MOVE OUT OF THE SOUTHERN PLAINS
ON LABOR DAY INTO THE MID-MISSISSIPPI AND TENNESSEE RIVER VALLEYS.
PW VALUES WILL INCREASE TO 1.7-1.9 INCHES WHICH IS WELL OVER THE 90TH
PERCENTILE FOR THIS TIME OF YEAR. EXPECT WIDESPREAD SHOWERS AND
STORMS MAINLY DURING THE AFTERNOON HOURS AND HAVE INCREASED POPS
INTO THE 60-70% RANGE FOR ALL OF CENTRAL ALABAMA. MODELS INDICATE
THAT SBCAPE VALUES WILL RANGE FROM 1000-2000 J/KG MEMORIAL DAY
AFTERNOON WITH 0-6KM SHEAR VALUES AROUND 30 KTS. THEREFORE...EXPECT
A FEW STRONG STORMS WILL BE POSSIBLE AGAIN WITH WIND GUSTS OF 40
MPH. IN ADDITION...EXPECT HEAVY DOWNPOURS WILL BE POSSIBLE WITH
STORMS THAT FORM AND THERE COULD BE A FEW ISOLATED AREAS OF MINOR
FLOODING IN AREAS OF POOR DRAINAGE. HOWEVER...DO NOT EXPECT ANY
WIDESPREAD FLOODING ISSUES WITH THE DRY START TO THE MONTH OF MAY.
EXPECT SIMILAR CONDITIONS ON TUESDAY AS ANOTHER SHORTWAVE TROUGH
MOVES THROUGH THE SOUTHERN PLAINS INTO THE MID-MISSISSIPPI AND
TENNESSE RIVER VALLEYS. MOISTURE VALUES WILL CONTINUE TO BE ELEVATED
WITH MODELS INDICATING PW VALUES APPROACHING 2 INCHES. SEVERE
WEATHER PARAMETERS ARE ABOUT THE SAME AND EXPECT A FEW STRONG STORMS
WILL BE POSSIBLE BUT EXPECT ACTIVITY WILL REMAIN BELOW SEVERE
LIMITS. ON WEDNESDAY...THE PATTERN SHOULD BEGIN TO SHIFT AS THE LAST
OF A SERIES OF SHORTWAVE TROUGHS MOVES THROUGH THE AREA AS THE RIDGE
TO THE EAST BREAKS DOWN. PW VALUES WILL BEGIN TO DROP SLIGHTLY BUT
REMAIN ELEVATED FOR THIS TIME OF YEAR. THEREFORE...POPS IN THE 50-
70% RANGE CONTINUE WEDNESDAY AFTERNOON.

LATE IN THE WEEK AN UPPER LEVEL RIDGE TRIES TO DEVELOP ALONG THE
GULF COAST WITH WEAK FLOW ALOFT. EXPECT MORE OF A TYPICAL EARLY
SUMMER TIME PATTERN DURING THIS PERIOD WITH A CHANCE FOR SCATTERED
AFTERNOON SHOWERS AND STORMS WITH TEMPERATURES WARMING INTO THE MID
AND UPPER 80S.

.AVIATION...
18Z TAF DISCUSSION.

SOME CONVECTION STARTING TO POP UP ACROSS THE SOUTHWEST PORTIONS
OF THE STATE. MOST OF THE THUNDER IS SOUTH AND WEST OF THE CENTRAL
ALABAMA TERMINALS. SOME SHOWERS MAY HIT TCL/MGM/TOI DURING THE
AFTERNOON AS THINGS PROGRESS OUT NORTHWARD AND EASTWARD WITH
DAYTIME HEATING. FOR NOW...NOT CONFIDENT ENOUGH TO MENTION
THUNDER AS CHANCES ARE LOWER. MVFR TO POSSIBLY SOME IFR STRATUS IS
EXPECTED TO RETURN TONIGHT IN THE LATE NIGHT HOURS WITH LOW LEVEL
ONSHORE FLOW EXPECTED OVERNIGHT. RAIN CHANCES GET BETTER FOR
MONDAY AFTERNOON.
