.SHORT TERM...(TODAY AND TONIGHT)CONDITIONS CONTINUE TO SET UP FOR A
FAIRLY ACTIVE WEATHER DAY...MOSTLY THIS AFTERNOON AND EARLY TONIGHT.
CURRENTLY...THE MOBILE CWFA IS UNDER A SLIGHT RISK FOR SEVERE
THUNDERSTORM DEVELOPMENT...WHICH APPEARS TO BE MOSTLY TO THE NORTH
AND WEST BEGINNING THIS AFTERNOON SHIFTING SOUTHWARD TOWARD THE
COAST THIS EVENING AND LATER TONIGHT. BOTH THE NAM AND GFS DEPICT
THE BEST LIFT OR INSTABILITY OUT AHEAD OF THE FRONT THIS AFTERNOON
AND EARLY TONIGHT...GENERALLY NORTH AND WEST OF A LINE STRETCHING
FROM LUCEDALE MS TO BUTLER AL. WITH CAPES CLIMBING TO ABOVE 3000
J/KG COMBINED WITH A 40 TO 50 KNOT 850 JET AND 1-3KM HELICITY VALUES
RANGING FROM 180 TO 200 M2/S2...GENERALLY IN THE AREAS MENTIONED
ABOVE THIS AFTERNOON AND EARLY TONIGHT...THE THREAT OF ROTATING
SUPERCELLS WILL EXIST FROM ABOUT 18Z TO 03Z TONIGHT. MORE STORMS CAN
BE EXPECTED FURTHER EAST LATER TONIGHT THOUGH THE INSTABILITY AND
VERTICAL SHEAR DECREASES SIGNIFICANTLY AFTER SUNSET. ENHANCED LIFT
ALOFT WILL CONTINUE THROUGH THE NIGHT AFFECTING MOST OF THE CWFA AS
THE RIGHT QUAD OF AN 80 KNOT JET PASSES OVER AL AND MS LATE TODAY
AND TONIGHT. STAY TUNED TO NOAA WEATHER RADIO OR LOCAL MEDIA OUTLETS
IN THREATENING WEATHER IS APPROACHING YOUR AREA. WILL STAY CLOSE TO
THE CURRENT MAV GUIDANCE FOR TEMPS THROUGH TONIGHT. /32

.LONG TERM...(SATURDAY THROUGH THURSDAY)AS SATURDAY DAWNS THE COLD
FRONT SHOULD BE NEAR INTERSTATE 65 WITH THE STRONGER STORMS WELL TO
THE EAST AND NORTHEAST OF FORECAST AREA...ANY SEVERE WEATHER SHOULD
HAVE OCCURRED THIS AFTERNOON AND EVENING. RAIN AND POSSIBLY ISOLATED
THUNDERSTORMS SATURDAY MORNING AS THE UPPER DIVERGENCE ASSOCIATED
WITH THE PASSING UPPER JET(H2) SHOULD DIMINISH AND END BY AFTERNOON
AS SKIES BEGIN TO CLEAR FROM NORTHWEST TO SOUTHEAST. CENTER OF
SURFACE HIGH WITH THIS SYSTEM IS WELL TO THE NORTHEAST BY SUNDAY
WITH WEAK RIDGING BACK TO THE SOUTHWEST AND ACROSS THE FORECAST
AREA. STILL SOME UNCERTAINTY AS TO ANY RAIN ON SUNDAY AS GFS
CONTINUES TO SHOW MOISTURE RETURNING TO THE SOUTHERN SECTIONS AS
FRONT DISSIPATES AND A DISTURBANCE IN THE UPPER FLOW MOVES OVER THE
COASTAL AREA SUNDAY AFTERNOON...ALREADY HAD SOME RAIN OVER THE
SOUTHERN SECTIONS FOR SUNDAY AND WILL LEAVE IN FORECAST FOR NOW. GFS
ACTUALLY LOOKS LIKE ITS CRANKING OUT SOME CONVECTIVE BULLETS OVER
THE NORTHERN GULF THE FIRST PART OF THE WEEK. KEPT PRECIPITATION IN
THE FORECAST FROM TUESDAY AFTERNOON ON AS SOUTHEAST FLOW
RETURNS...INCREASING THE PRECIPITABLE WATER VALUES UP TO AN INCH AND
A HALF FOR THE REMAINDER OF THE WEEK. WITH ANOTHER COLD FRONT
APPROACHING THE AREA LATE IN THE WEEK...SHOULD BE ENOUGH LIFT AND
INSTABILITY TO GO WITH THE AMPLE MOISTURE TO HAVE ISOLATED TO
SCATTERED SHOWERS AND THUNDERSTORMS MOST ANY TIME...WITH BETTER
CHANCES IN THE AFTERNOONS. HIGH TEMPERATURES GENERALLY 75 TO 80 WITH
POPS 20 TO 30 PERCENT. /11

&&

.MARINE...A MODERATE TO STRONG SOUTHERLY WIND FLOW WILL CONTINUE
TODAY AND TONIGHT AHEAD OF COLD FRONT APPROACHING FROM THE WEST.

TONIGHT AND EARLY SATURDAY. SOME STORMS COULD BE STRONG TO SEVERE
OVER WESTERN PARTS OF THE MARINE LATE THIS AFTERNOON AND EARLY
TONIGHT...SHIFTING SOUTH AND EAST LATER TONIGHT AND EARLY SATURDAY
AS THE COLD FRONT APPROACHES FROM THE NORTHWEST. A LIGHT NORTHERLY
WIND FLOW WILL DEVELOP IN THE WAKE OF THE FRONT LATE SATURDAY
THROUGH EARLY SUNDAY BECOMING EAST TO SOUTHEAST IN THE AFTERNOON.
EASTERLY WINDS AND SEAS WILL BUILD SLIGHTLY BY EARLY NEXT WEEK AS
HIGH PRESSURE STRENGTHENS ALONG THE EASTERN SEABOARD. /32
