.SHORT TERM...(TODAY...TONIGHT AND EARLY SUNDAY) THE LATEST SURFACE
ANALYSIS SHOWS AN AREA OF LOW PRESSURE DEVELOPING OVER SOUTH TEXAS
WITH A WARM FRONT STRETCHING FROM SOUTHEAST TEXAS EASTWARD ACROSS
EXTREME SOUTH MISSISSIPPI...ALABAMA AND GEORGIA. SOUTH OF THE WARM
FRONT AREAS OF DENSE FOG HAVE DEVELOPED THIS MORNING AND WILL LIKELY
PERSIST THRU MID TO LATE MORNING IN MANY AREAS. AS THE FOG AND LOW
CLOUDS GRADUALLY DISSIPATE BY EARLY AFTERNOON...EXPECT THE TEXAS LOW
TO START DRIFTING NORTHEASTWARD AS A STRONG UPPER SHORTWAVE DIGS IN
OVER WEST TEXAS. THE SHORTWAVE CUTS OFF OVER NORTH CENTRAL TEXAS BY
MIDNIGHT TONIGHT WHILE THE ETA AND UKMET AGREE ON TAKING THE SURFACE
LOW INTO SOUTHERN MS BY THE SAME TIME. THE GFS IS A BIT FASTER WITH
THE LOW OVER NORTH MS BY MIDNIGHT. PREFER THE ETA AND UKMET
SOLUTIONS AT THIS TIME. AHEAD OF THE APPROACHING LOWS...EXPECT
SCATTERED STORMS TO DEVELOP OVER THE AREA BY THIS AFTERNOON AS A
VORT MAX EXITS TEXAS AND TRACKS ACROSS THE AREA DURING THE
AFTERNOON. STORMS SHOULD BECOME MORE NUMEROUS THIS EVENING AS THE
SURFACE LOW APPROACHES...PLACING THE AREA DEEP IN THE WARM SECTOR
WITH A STRONG DIFFLUENT JET OVERHEAD. THE ETA SHOWS 1500-2000 CAPES
NOSING INTO THE AREA BY MID AFTERNOON AND DRIFTING EASTWARD OVER THE
WESTERN FLORIDA PANHANDLE DURING THE EVENING. THIS COUPLED WITH A
STRONG DIFFLUENT JET OVERHEAD SUGGESTS THE THREAT OF STRONG STORMS
DEVELOPING OVER THE COASTAL WATERS FROM THIS AFTERNOON THROUGH THE
EVENING AND TRACKING NORTHEASTWARD ACROSS MUCH OF SOUTH ALABAMA AND
THE WESTERN FLORIDA PANHANDLE. ALTHO THIS THREAT CONTINUES AFTER
MIDNIGHT...A SECOND THREAT APPROACHES IN THE FORM OF A SQUALL LINE
DEVELOPING AHEAD OF THE APPROACHING COLD FRONT FROM THE WEST. THE
SQUALL LINE PUSHES ACROSS MAINLY THE SOUTHERN HALF OF THE CWA...TO
INCLUDE THE COASTAL WATERS...DURING THE EARLY SUNDAY MORNING HOURS.
AS FOR SEVERE WEATHER...THE ETA SHOWS BEST INSTABILITIES AND LOW
LEVEL CONVERGENCE OVER THE AREA THIS AFTERNOON...SO COULD SEE A FEW
STORMS PULSE SEVERE WITH LARGE HAIL AND DAMAGING WINDS THE MAIN
THREAT THRU THIS EVENING...ALTHO AN ISOLATED TORNADO CANNOT BE RULED
OUT. BEST WIND SHEAR AND INSTABILITIES POOL OVER THE ALABAMA COASTAL
COUNTIES AND THE WESTERN FLORIDA PANHANDLE BY EARLY SUNDAY
MORNING...SO STORMS ASSOCIATED WITH THE SQUALL LINE...AND/OR AHEAD
OF THE SQUALL LINE COULD BE SEVERE WITH DAMAGING WINDS AND ISOLATED
TORNADOES BEING THE MAIN THREAT. EXPECT THE SQUALL LINE AND BEST
THREAT OF SEVERE WEATHER TO PUSH EAST OF DESTIN BY NOONISH
SUNDAY...BUT TIMING IS STILL UNCERTAIN.

SUNDAY AFTERNOON AND MONDAY...BY SUNDAY AFTERNOON AND EVENING...
BEHIND THE SQUALL LINE WE SEE A STRONG VORTMAX. SOME SCT TSTMS COULD
FOLLOW WITH SOME SEVERE BUT WE SAY SO WITH SOME APPREHENSION AND A
WARY EYE ON WHAT WILL HAPPEN IN LIGHT OF WHAT THE GFS IS DOING WITH
THIS. THUS FOR THE REMAINING PERIOD 4 THROUGH 5...THE GFS WILL
EVENTUALLY BLEND INTO THE FINAL SOLUTION INTO THE EXTENDED PERIODS.

&&

.EXTENDED...SHOULD BE PRETTY QUIET DURING MOST OF THIS WEEK SAVE
THURSDAY WHEN THE NEXT TROUGH DIGS OVER THE MISSISSIPPI VALLEY AND
SHOWING SIGNS THAT IT WANTS TO INITIALLY NEGATIVELY TILT. AFTER THE
ATTENDANT FRONT PASSES...IT SEEMS TO STRETCH OUT INTO A POSITIVE
TILT TO GET RID OF THE MOMENTUM ANOMALY IT WOULD BRING...AND STALL
OVER THE PIEDMONT. THAT COULD GET US INTO A SOUPY STATIONARY FRONTAL
SITUATION LEAVING US WITH A WET WEEKEND. HOWEVER THAT IS NOT
REFLECTED IN MEX NUMBERS AND THUS WILL NOT APPEAR IN PRODUCTS ISSUED
THIS MORNING. NONETHELESS IT IS SOMETHING TO CONSIDER...AND...IN ANY
CASE...THE GFS WANTS TO COOL THINGS CONSIDERABLY AT THAT POINT.

&&

.MARINE...THE WEAK AREA OF LOW PRESSURE DEVELOPING OVER SOUTH TEXAS
WILL HELP MAINTAIN A LIGHT ONSHORE FLOW TODAY. ONSHORE WINDS AND
SEAS WILL INCREASE A BIT FROM LATE THIS AFTERNOON THROUGH EARLY
SUNDAY MORNING AS THE TEXAS LOW MOVES NORTHEAST INTO CENTRAL
MISSISSIPPI BY SUNDAY MORNING. THE LOW WILL BRING SCATTERED SHOWERS
AND THUNDERSTORMS TO THE AREA BEGINNING THIS AFTERNOON...THEN
BECOMING MORE NUMEROUS THIS EVENING. A SQUALL LINE IS EXPECTED TO
DEVELOP AHEAD OF A COLD FRONT AND MOVE ACROSS THE MARINE WATERS
SUNDAY MORNING WITH NUMEROUS STORMS BRINGING STRONG GUSTY WINDS...
HEAVY DOWNPOURS AND FREQUENT LIGHTNING. AFTER THE SQUALL LINE WOULD
LEAVE SOME SCT TSTMS...A COUPLE OF SEVERE ONES POSSIBLE...BEFORE A
COLD FRONT FOLLOWS AND PUSHES ACROSS THE AREA LATER SUNDAY AFTERNOON
AND EVENING. A STRONG OFFSHORE FLOW WILL DEVELOP BEHIND THE FRONT AND
CONTINUE THROUGH MIDDAY MONDAY. WINDS AND SEAS WILL GRADUALLY SUBSIDE
LATE MONDAY INTO TUESDAY.

&&

.FIRE WEATHER...A WET WEEKEND LEAVES US WITH LITTLE TO REPORT EXCEPT
THAT THE MIN RH COULD GET MARGINAL TUESDAY. INITIAL THINKING IS HIGH
30S BUT THIS CAN CHANGE OVER TIME. NOTHING ELSE OF PARTICULAR
IMPORT.

600 AM CST SAT MAR 26 2005

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTHWEST ALABAMA...SOUTHEAST
MISSISSIPPI AND THE EXTREME WESTERN PORTION OF THE FLORIDA PANHANDLE.

.DAY ONE...TODAY AND TONIGHT

...A DENSE FOG ADVISORY IS IN EFFECT FOR PORTIONS OF SOUTHWEST
ALABAMA AND THE WESTERN FLORIDA PANHANDLE THIS MORNING...

...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS FROM THIS
MORNING THROUGH TONIGHT...

AREAS OF DENSE FOG WILL GRADUALLY LIFT BY MID TO LATE MORNING.

SCATTERED THUNDERSTORMS WILL BEGIN TO DEVELOP OVER THE COASTAL
WATERS THIS MORNING. SOME OF THESE STORMS WILL BEGIN TO PUSH INLAND
OVER SOUTH ALABAMA AND THE WESTERN FLORIDA PANHANDLE DURING THE
MORNING HOURS. A FEW OF THESE STORMS COULD BECOME STRONG OR EVEN
SEVERE WITH THE POTENTIAL FOR STRONG DOWNBURST WINDS AND LARGE HAIL.

NUMEROUS SHOWERS AND THUNDERSTORMS WILL DEVELOP OVER THE AREA THIS
AFTERNOON AND EVENING AS A STRONG STORM SYSTEM DEVELOPS OVER TEXAS
AND BEGINS TO PUSH EASTWARD. A FEW STORMS COULD BE STRONG TO SEVERE
AS A SERIES OF UPPER LEVEL DISTURBANCES INTERACT WITH INCREASING GULF
MOISTURE AND INSTABILITIES. THESE STORMS WILL HAVE THE POTENTIAL TO
PRODUCE LARGE HAIL...DAMAGING WINDS AND POSSIBLY ISOLATED TORNADOES.
A BETTER CHANCE OF SEVERE STORMS WILL BE OVERNIGHT AS A SQUALL LINE
IS EXPECTED TO MOVE ACROSS THE REGION EARLY SUNDAY MORNING. STRONG
DAMAGING WINDS AND ISOLATED TORNADOES ARE POSSIBLE ALONG AND IN
ADVANCE OF THE SQUALL LINE.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY...

BY MID TO LATE SUNDAY MORNING THE SQUALL LINE OF STRONG TO SEVERE
STORMS IS EXPECTED TO PUSH EAST OF THE AREA. DURING SUNDAY
AFTERNOON...SOME ISOLATED TO SCATTERED THUNDERSTORMS COULD DEVELOP
AS THE STORM SYSTEMS TRACKS ACROSS THE TENNESSEE VALLEY AND DRAGS A
COLD FRONT ACROSS THE AREA LATE SUNDAY AFTERNOON AND EARLY EVENING. A
FEW STORMS COULD BECOME STRONG ENOUGH TO PRODUCE LARGE HAIL AND
STRONG DOWNBURST WINDS. HOWEVER...WIDESPREAD SEVERE WEATHER IS NOT
EXPECTED SUNDAY AFTERNOON OR EVENING AT THIS TIME.

OTHERWISE...NO HAZARDOUS WEATHER IS EXPECTED FROM SUNDAY NIGHT
THROUGH FRIDAY.

.SPOTTER INFORMATION STATEMENT...
