AREA FORECAST DISCUSSION...UPDATE...
NATIONAL WEATHER SERVICE MOBILE AL
1130 PM CDT MON APR 7 2014

.AVIATION...[08.06Z ISSUANCE]...MOSTLY VFR THROUGH 09.06Z. COULD
ALSO SEE SOME MVFR CEILINGS BRIEFLY IN AND AROUND SCATTERED SHOWERS
AND THUNDERSTORMS OCCURRING MOSTLY BETWEEN 08.18Z AND 09.00Z. WINDS
WILL BE MOSTLY NORTHWEST AT 5 TO 10 KNOTS THROUGH 08.18Z SHIFTING
WEST THEN NORTHWEST AT 10 TO 20 KNOTS THROUGH 09.06Z. 32/EE

.MARINE...EXPECT A MODERATE TO STRONG OFFSHORE FLOW FOR THE REST OF
TONIGHT SHIFTING WEST AND DIMINISHING SLIGHTLY DURING THE MID TO
LATE MORNING HOURS ON TUES THEN SHIFTING NORTHWEST AND BUILDING TO
18 TO 25 KNOTS WITH HIGHER GUSTS LATE TUES AFTERNOON THROUGH MIDDAY
WED AS A STRONG COLD FRONT MOVES SOUTH ACROSS MUCH OF THE NORTHERN
AND CENTRAL GULF. SMALL CRAFT SHOULD EXERCISE CAUTION FOR THE
REMAINDER OF TONIGHT. SMALL CRAFT ADVISORY MAY BE REQUIRED WITH THE
STRONGER OFFSHORE LATE TUE AND TUES NIGHT. 32/EE

&&

PREVIOUS DISCUSSION.../ISSUED AT 335 PM CDT MON APR 7 2014/

.SHORT TERM (TONIGHT AND TUESDAY)...SURFACE COLD FRONT POISED TO
CLEAR ENTIRE AREA BY START OF PERIOD (AND SUBSEQUENT QUIET OVERNIGHT
PERIOD WITH LOWS IN THE MID 40S OVER THE INTERIOR AND LOW TO MOD 50S
ALONG THE COAST). WEAK SURFACE HIGH PRESSURE BUILDS OVERNIGHT.

CAVEATS AND QUICK CHANGES BY TOMORROW AFTERNOON. ALOFT...A
PROGRESSIVE
POS-TILT LONGWAVE (SEEN NICELY IN WV IMAGERY) APPROACHES
OUR AREA FROM THE WEST AND INDUCES SFC PRES FALLS (AND ASSOC LOWER
TROPOSPHERIC CONVERGENCE) AHEAD OF IT. SIMULTANEOUSLY...AN AREA OF
MID-TROPOSPHERIC MOISTURE CENTERED BETWEEN 400-700 HPA (NEAR THE
BASE OF THE AFOREMENTIONED PROGRESSIVE TROUGH AND ALREADY PRESENT
CURRENTLY PER WV IMAGERY) MOVES INTO THE REGION EARLY TOMORROW
(ALONG WITH VERY COLD 500 HPA TEMPS (-20 TO -23 DEC(C)) AND FORCES
SCATTERED TO NUMEROUS RAINSHOWERS WITH ISOLD THUNDERSTORMS ON THE
COLD SIDE OF THE FRONT DURING PEAK HEATING TIME.  AM FORECASTING
MOSTLY RAINSHOWERS WITH SOME ELEVATED THUNDER AFTER MID-MORNING AND
THIS ENDURES INTO EARLY EVENING BEFORE LOSS OF INSOLATION (AS LOWER
LEVELS QUICKLY STABILIZE). FORECAST SOUNDINGS INDICATE THAT IF SFC
TEMPS HEAT TO 20 DEG(C)...WHICH IS WHAT WE ARE FORECASTING FOR HIGHS
TOMORROW AFTERNOON (I.E., UPPER 60S TO LOWER 70S(F))...THEN PARCELS
WOULD HAVE A FREE RIDE TO THEIR RESPECTIVE EQUILIBRIUM LEVELS (23-27
KFT). UPPER HALF OF THE FORECAST SOUNDING IS UNUSUALLY COLD. WE ARE
THINKING SOME SMALL HAIL IS POSSIBLE TOMORROW AFTERNOON (MOSTLY 0.5"
DIAMETER BUT SOME 1" POSSIBLE IN STRONGER UPDRAFTS) AND EVEN A WIND
GUST POTENTIAL EXISTS UNTIL THE MID-LEVELS MOISTEN WITH SUBSEQUENT
SHOWERS FOR ANY ONE LOCATION. WE DO REALIZE THAT UPDRAFTS WILL BE
RELATIVELY WEAK AND AMOUNT OF CAPE IN HAIL-GROWTH ZONE WILL BE
LIMITED...HOWEVER...SIGNIFICANT STORM RELATIVE FLOW EXISTS AND
HODOGRAPH IS 'STRAIGHT-LINE' WHICH FAVORS SOME MULTICELLS WITH
SPLITTING STORMS. TOMORROW AFTERNOON'S PRECIPITATION DEVELOPS AND
MOVES FROM WEST TO EAST. DID GO BELOW GUIDANCE ON TOMORROW'S MAX
TEMPS GIVEN AMOUNT OF CLOUDS ASSOCIATED WITH LARGE-SCALE FORCING AS
UPPER TROUGH APPROACHES. /23 JMM

&&

.LONG TERM (WEDNESDAY THROUGH MONDAY)...NORTHWESTERLY UPPER FLOW
RETURNS TO THE AREA WEDNESDAY AS THE UPPER TROUGH MOVES EAST. THIS
WILL LEAD TO BUILDING HIGH PRESSURE AT THE SURFACE...RESULTING IN
DRY CONDITIONS AND CLEAR SKIES. THE UPPER FLOW WILL BECOME ZONAL AND
SFC HIGH PRESSURE WILL BUILD EASTWARD THROUGH THE END OF THE WEEK.
AS THE HIGH MOVES EAST..RETURN FLOW WILL BRING INCREASING MOISTURE
BACK INTO THE AREA LATE IN THE WEEK INTO EARLY NEXT WEEK. A COLD
FRONT IS FORECAST TO APPROACH THE AREA EARLY NEXT WEEK...RETURNING
CHANCES OF SHOWERS AND THUNDERSTORMS TO THE AREA. TEMPERATURES START
THE PERIOD BELOW NORMAL BUT RAPIDLY WARM BACK TO ABOVE NORMAL BY THE
END OF THE WEEK. /13

&&

.AVIATION [07.18Z TAF ISSUANCE]...FRONTAL PASSAGE OCCURS THIS
AFTERNOON AND BRINGS A WEST NORTHWESTERLY FLOW IN ITS WAKE. LINGERING
LIGHT SHRA OVER PNS...ENDS BY 20Z. MAIN CONVECTIVE LINE ADVANCES EAST
OVER THE NORTHERN FLORIDA PENINSULA THIS AFTERNOON. SATELLITE SHOWS
LOW END MVFR TO IFR CIGS PIVOTING EASTWARD OVER THE SOUTHERN STATES
IN THE NEAR TERM AND WILL CARRY THESE BASES IN TAFS. /10

&&

.MARINE...SMALL CRAFT CONDITIONS WILL LIKELY REDEVELOP TUESDAY NIGHT
AND ENDURE THROUGH MIDDAY WEDNESDAY AS STRONG HIGH PRESSURE BUILDS.
WINDS DECREASE AND SEAS SUBSIDE WEDNESDAY NIGHT AND THE REMAINDER OF
THE WEEK SHOULD CONTAIN NO MARINE HAZARDS. /23 JMM
