AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
600 AM CST SAT JAN 21 2012

.UPDATE...
AVIATION DISCUSSION.

&&

.SHORT TERM...TODAY THROUGH MONDAY.

THUNDERSTORMS HAVE DEVELOPED ALONG A COLD FRONT THAT HAS PUSHED
INTO NORTHERN MISSISSIPPI AND TENNESSEE. WITH THE APPROACH OF AN
UPPER LEVEL TROUGH CURRENTLY IN THE SOUTHERN PLAINS PROVIDING 40
TO 50 KTS OF 0-6 KM BULK SHEAR... EXPECT THIS LINE OF STORMS TO
MAINTAIN ITSELF AS IT BEGINS TO ENTER INTO CENTRAL ALABAMA. IN
TERMS OF THE SEVERE THREAT THIS MORNING AND AFTERNOON... REASONING
HAS NOT CHANGED MUCH FROM BEFORE. MODEST CAPE JUST AHEAD OF THE
FRONT COMBINED WITH SUFFICIENT LOW LEVEL SHEAR WILL SUPPORT
ORGANIZED THUNDERSTORMS... SOME OF WHICH MAY BE SEVERE. LOOKS LIKE
THE CHANCE FOR SEVERE INCREASES AFTER 6 AM IN OUR NORTHWEST AREAS
AS GREATER INSTABILITY MOVES IN FROM MS. AS THE DAY PROGRESSES...
THE BOUNDARY LAYER SOUTH OF THE FRONT SHOULD DESTABILIZE FAIRLY
WELL GIVEN THE 60 PLUS DEW POINTS ALREADY IN PLACE AND JUST A FEW
DEGREES OF DAYTIME HEATING. THIS WILL SUPPORT DAMAGING WINDS AND
LARGE HAIL ALONG THE LINE. SHALLOW CONVECTION HAS ALSO DEVELOP
AHEAD OF THE FRONT... AND BEARS WATCHING. A LIMITING FACTOR FOR
THE SEVERE THREAT TODAY WILL BE THE DEPARTURE OF THE BEST SHEAR
IN THE AFTERNOON AS THE UPPER SHORTWAVE TROUGH EJECTS EASTWARD.

WITH REGARDS TO TORNADO POTENTIAL... THERE IS A LOW CHANCE...
ESPECIALLY ACROSS THE WESTERN PART OF CENTRAL ALABAMA THIS
MORNING... WHERE LOW LEVEL SHEAR IS CURRENTLY MAXIMIZED. ANY
DISCRETE CELLS IN THIS AREA WILL HAVE TO BE CLOSELY MONITORED.
OVERALL... SINCE SHEAR VECTORS ARE STILL ROUGHLY PARALLEL TO THE
FRONT... THINK PRIMARY THREATS TODAY WILL BE DAMAGING WINDS AND
LARGE HAIL ALONG THE CURRENT LINE OF THUNDERSTORMS.

THE LONGWAVE UPPER TROUGH NOW MAKING LANDFALL ON THE PACIFIC COAST
WILL SUPPORT DEVELOPMENT OF A SURFACE LOW OVER THE CENTRAL PLAINS
SUNDAY... WHICH WILL CAUSE THE CURRENT COLD FRONT TO STALL LATE
TONIGHT AND THEN START LIFTING BACK NORTHWARD AS A WARM FRONT ON
SUNDAY. THE FORCING ASSOCIATED WITH THE NEXT COLD FRONT LOOKS TO
ARRIVE LATE SUNDAY FOR OUR AREA. CAPE VALUES LOOK GOOD DURING
SUNDAY AFTERNOON... BUT DECREASE QUICKLY LATER IN THE EVENING WITH
THE LOSS OF DAYTIME HEATING. CONVERSELY... THE BEST SHEAR LOOKS
LIKE IT WILL ARRIVE LATER. WITH ALL THAT SAID... THINK THERE IS A
CHANCE FOR SOME SEVERE STORMS... PRIMARILY DAMAGING WINDS ALONG A
LINE OF THUNDERSTORMS ASSOCIATED WITH THE COLD FRONT FROM LATE
SUNDAY EVENING AND CONTINUING OVERNIGHT TO MONDAY MORNING.
TORNADO THREAT LOOKS LOW... JUST LIKE TODAY... BUT IF ANY STORMS
FORM OUT AHEAD OF THE COLD FRONT SUNDAY EVENING... THEY COULD
ROTATE. CONTINUED WITH THE SEVERE WORDING IN THE HWO FOR THIS TIME
FRAME... AND INCREASED CONFIDENCE IN WORDING.

77/GLEASON

.LONG TERM...TUESDAY THROUGH SATURDAY.

THERE WILL BE A QUICK LIVED COOL DOWN ON TUESDAY AHEAD OF THE RETURN
FLOW THAT WILL ONCE AGAIN BEGIN ON WEDNESDAY AHEAD OF THE NEXT
SYSTEM. IN FACT THE RETURN FLOW WILL BE SO QUICK WILL GO AHEAD AND
INCLUDE SLIGHT CHANCE POPS IN FOR TUESDAY NIGHT/WEDNESDAY MORNING
WITH CONDITIONS GENERALLY ONLY BEING AFTER MIDNIGHT.

RAIN CHANCES INCREASE THROUGHOUT THE DAY ON WEDNESDAY/WEDNESDAY
NIGHT AS WE WAIT FOR AN UPPER LOW TO SWING CLOSER TO THE AREA. AT
THIS TIME IT APPEARS THAT THE BEST RAIN CHANCES WILL WORK IN BY
THURSDAY AND INTO THURSDAY NIGHT AS THE SURFACE LOW SLIDES NORTHEAST
THROUGH THE AREA. RAIN CHANCES REMAIN HIGH THROUGH FRIDAY AS WELL AS
WE AWAIT THE UPPER LEVEL LOW TO SWING THROUGH AS WELL.

THE BIGGEST CHANGE TO THE EXTENDED...BESIDES SLOWING DOWN THE FRONT
FOR THE END OF THE WEEK...WAS THE INCREASED LOW TEMPERATURES FOR THE
LATER HALF OF THE WEEK. GFS MOS IS REALLY TOO LOW AND WENT WITH A
MODIFIED GFS VERSION FOR THE EXTENDED PERIOD. REALLY DO NOT SEE HOW
TEMPERATURES WILL DROP MUCH BELOW THE MID 50S AS SOUTHERLY FLOW
REALLY KICKS INTO THE AREA. STILL A LOT OF TIMING TO WORK OUT
WITH THIS PERIOD SO STAY TUNED.

.AVIATION...
12Z TAF DISCUSSION.

IMMEDIATE CONCERN IS LLWS WHICH WAS INDICATED BY UPPER AIR
SOUNDING...AND HAVE INCLUDED AT ALL LOCATIONS UNTIL 15Z WHEN MIXING
WILL INCREASE SURFACE WINDS TO END THREAT. HAVE FORECASTED TSRA
BASED ON TIMING OF LINE OF STORMS AHEAD OF A COLD FRONT THAT WILL
PUSH THROUGH CENTRAL ALABAMA FROM NORTH TO SOUTH DURING THE MORNING
AND AFTERNOON. IN ADDITION...ISOLATED TO SCATTERED STORMS WILL
DEVELOP AHEAD OF THE MAIN LINE OF STORMS AND HAVE PUT VCTS IN TAFS
PRIOR TO FRONTAL PASSAGE. AFTER PASSAGE...SKIES WILL BEGIN TO
CLEAR...BUT ANTICIPATE WIDESPREAD IFR STRATUS AND FG CONDITIONS DUE
TO RADIATIONAL COOLING AFTER SUNSET. SOME AREAS MAY SEE LIFR
CONDITIONS AFT 06Z. STEFKOVICH
