AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
348 PM CST SAT DEC 11 2010

.SHORT TERM...TONIGHT THROUGH MONDAY NIGHT.

A POWERFUL STORM SYSTEM POISED TO IMPACT CENTRAL ALABAMA IN THE SHORT
TERM. SEVERAL POTENTIAL HAZARDS THIS PERIOD ALONG WITH AN ARCTIC
INTRUSION.

PRE-FRONTAL CONVERGENCE ZONE STARTING TO BECOME ACTIVE FROM NORTHERN
MISSISSIPPI INTO SE ARKANSAS AND INTO LOUISIANA. SOME PEAKS OF
SUNSHINE HAVE HELPED WARM THINGS UP INTO THE 60S AND 70S WEST...
IMPROVING THE LIMITED INSTABILITY. A RATHER NARROW WARM SECTOR
EXIST WHERE MUCAPES ARE AROUND 500...LIS -1 TO -2. SURFACE DEW
POINTS ARE TRYING TO INCREASE UNDER THE SPATIALLY LIMITED SOUTHERLY
FLOW...BUT SOME MID 50S STARTING TO CREEP INTO THE MISSISSIPPI
DELTA REGION. ALL THIS UNDER 50KT EFFECTIVE SHEAR AND LARGELY RIGHT
TURNING HODOGRAPHS. THIS SMALL WARM SECTOR APPROACHES CENTRAL
ALABAMA THIS EVENING. MODEL CONSENSUS HAS THE MOISTURE RETURN
LIMITED INTO OUR AREA...THEREFORE LIMITING THE INSTABILITY. NEW
TORNADO WATCH GOING UP TO OUR WEST FOR PARTS OF MISSISSIPPI.
CURRENT THINKING IS THAT A FEW STRONGER STORMS MAY MAKE IT INTO FAR
SOUTHWESTERN AREAS BETWEEN 6 AND 10 PM. MODEL CONSENSUS JUST CUTS
OFF THE RETURN FLOW WITH THE FAST APPROACH OF THE COLD FRONT.
ADDITIONALLY...TOO MUCH SHEAR AND LOW CAPES WILL BE TOUGH TO ACHIEVE
SUSTAINED UPDRAFTS. WILL CLOSELY MONITOR THE BOUNDARY LAYER SITUATION
BUT CONFIDENCE IS NOT TOO HIGH DUE TO LIMITED INSTABILITY DUE TO
MOISTURE DEFICIENCY.

WILL GO AHEAD AN ISSUE AN WIND ADVISORY AT 4 PM AND RUN IT THROUGH
SUNDAY AFTERNOON. AN EXTENSION MAY WELL BE NEEDED BUT WILL DEAL
WITH THESE PERIODS FIRST. MARGINAL CRITERIA WINDS WILL BE PRESENT
AHEAD AND JUST BEHIND THE FRONT THROUGH TONIGHT. A FEW GUSTS MAY
REACH 30 MPH WHILE SUSTAINED WINDS WILL BE 10 TO 20 MPH AT TIMES.
THESE WINDS WILL ONLY BE A PRELUDE TO THE STRONGER WINDS EXPECTED
BEHIND THE FRONT. WINDS JUST AFTER SUNRISE WILL QUICKLY INCREASE AND
BE SUSTAINED AROUND 20 MPH. A FEW GUSTS MAY TOUCH THE 35 TO 40 MPH
RANGE. THESE GUSTY WINDS WILL LIKELY EXTEND INTO SUNDAY NIGHT WITH
SOME DECREASE NOTED THROUGH THE DAY ON MONDAY.

THE POLAR FRONT WILL PUSH THROUGH THE AREA TONIGHT...FOLLOWED BY AN
ARCTIC FRONT SUNDAY. WILL KEEP THE FORECAST TREND OF HANGING CLOSE
TO THE LOW END GFS ENSEMBLE LOW TEMPS MONDAY AND TUESDAY MORNING.
WILL ISSUE A HARD FREEZE WATCH FOR MONDAY MORNING AS LOWS DIP INTO
THE 13 TO 20 DEGREE RANGE. WINDS WILL ALSO REMAIN UP DURING THIS
STRONG COLD AIR ADVECTION PERIOD AS WIND CHILL VALUES WILL DIP INTO
THE SINGLE DIGITS. OVERNIGHT LOWS BY TUESDAY MORNING WILL BE THE
COLDEST WITH THIS SNAP....AROUND 10 DEGREES IN A FEW NORMALLY
COLDER PLACES...MANY AREAS IN THE MID TEENS. WINDS WILL BE LIGHTER
AND WIND CHILL VALUES CORRESPONDINGLY WILL BE A BIT HIGHER.

AS FAR AS PRECIPITATION IS CONCERNED...A GOOD SHOT AT RAIN TONIGHT.
RAIN AMOUNTS WILL GENERALLY AVERAGE ONE HALF TO ONE INCH AREA WIDE.
LOOKING AT VARIOUS MODEL SOLUTION SOUNDINGS...THE DRY AIR
INVADES/DEEP MOISTURE EXITS BEFORE THE COLD AIR. THEREFORE...DO NOT
HAVE RAIN CHANGING TO SNOW OVERNIGHT. BUT AS THE COLD AIR SETTLES
IN SUNDAY...THE NORTHWEST FLOW AND SOME WRAPAROUND MOISTURE WILL
GIVE US A CHANCE AT SNOW SHOWERS. WILL NOT MENTION ANY ACCUMULATION
AT THIS TIME DUE TO THE VARIED NATURE OF SHOWERS. THE BEST SPOT TO
SEE ANY OF THE WHITE STUFF WILL BE ACROSS THE HIGHER ELEVATIONS AND
TERRAIN AREAS EAST AND NORTHEAST.

75/LINHARES

&&

.LONG TERM...TUESDAY THROUGH SATURDAY.

TUESDAY PROMISES A MODEST WARMING TREND. OF COURSE...WARMING IN
THIS CASE IS ALL RELATIVE...CONSIDERING THE TEMPERATURES THE
PREVIOUS 24 TO 48 HOURS. AFTER THAT...FORECAST CONFIDENCE DROPS
FASTER THAN THE FIRST DROP ON ON CONEY ISLAND CYCLONE.

LONG RANGE MODELS STILL HAVING A DIFFICULT TIME COMING TO A
CONSENSUS ON WHAT TRANSPIRES WEDNESDAY THROUGH THE END OF THE WEEK.
THE GFS...ECMWF...AND GEM DO AGREE THAT THE UPPER LEVEL FLOW WILL
FLATTEN OUT AND BECOME MORE ZONAL DURING THIS TIME FRAME. WITH A
FRONTAL BOUNDARY LURKING ALONG THE COAST...AN APPROACHING SHORTWAVE
TROUGH WOULD SET THE STAGE FOR A QUICK OVERRUNNING PRECIP EVENT. THE
PROBLEM IS...THESE MODELS ARE NOT HANDLING THE ARRIVAL OF SAID
SHORTWAVE WELL AT ALL. THE GFS HAS BEEN CONSISTENT WITH ITSELF...IN
STARTING THE WARM ADVECTION AND OVERRUNNING PRECIP SOONER THAN THE
OTHER MODELS. THE 12Z RUNS ARE NO DIFFERENT...WITH LIGHT RAIN
BREAKING OUT IN THE NORTHERN COUNTIES AS EARLY AS 12Z WEDNESDAY
MORNING. THE PROBLEM WITH THIS REMAINS THAT GROUND TEMPERATURES ARE
FORECAST TO BE NEAR OR BELOW FREEZING FOR THIS SAME AREA.

WHILE I WOULD NORMALLY HEDGE MY FORECAST TO THE 2 VERSUS 1 SLOWER
MODEL SOLUTIONS...I THINK THAT THERE IS STILL JUST ENOUGH OF A
FREEZING RAIN THREAT TO MENTION IN OUR VARIOUS PRODUCTS. AGAIN...
EVEN THE GFS SUGGESTS THAT RAINFALL AMOUNTS WILL BE VERY LIGHT
DURING THE CRITICAL SUB-FREEZING TIME...SO NO BIG PROBLEMS ARE
EXPECTED. AND CONDITIONS ARE FORECAST TO STEADILY WARM WEDNESDAY AND
WEDNESDAY NIGHT...SO ANYTHING METEOROLOGICAL THAT IS FALLING FROM
THE SKY SHOULD STAY IN THE LIQUID FORM BY WEDNESDAY EVENING.

GIVEN THE 24 HOUR DIFFERENCE IN TIMING BETWEEN THE LONG RANGE MODELS
ON THE RAIN'S ONSET...AND SUBSEQUENT DEPARTURE...FORECAST CONFIDENCE
REMAINS ABOUT AS LOW AS IT CAN GET THROUGH THE END OF THE WEEK AND
INTO NEXT WEEKEND. THEREFORE...THE FORECAST WAS BASED ON A BLEND OF
ALL MODELS.

61

&&

.AVIATION...18Z TAF DISCUSSION.

MULTIPLE THINGS GOING ON DURING THIS TAF PERIOD.  QUIET VFR
CONDITIONS WILL QUICKLY DETERIORATE THIS AFTERNOON AS SHOWERS AND
ISOLATED TS APPROACH FROM THE WEST.  CIGS SHOULD BOTTOM OUT AT MVFR
AROUND 02Z AT TCL AND WINDS WILL BEGIN TO PICK UP OUT OF THE
SOUTH...WITH THESE TYPE OF CONDITIONS SPREADING EASTWARD THROUGHOUT
THE EVENING HOURS.

FROPA WILL BE THE NEXT CONCERN BECAUSE IT SHOULD BE A FAIRLY ABRUPT
SHIFT FROM SOUTH TO WEST AS THE FRONT PASSES ANY GIVEN AREA WITH A
CONTINUING 10-12 KTS EVEN AFTER THE SHIFT.  RAINS SHOULD END WITH
FROPA AS WELL.

NORMALLY WE ONLY DO 5-LINE TAFS...BUT I FELT THE NEED TO THROW IN
THE 6TH LINE ON OUR NORTHERN TAFS BECAUSE EVERYONE WILL SEE WINDS
PICK UP AFTER DAYBREAK SUNDAY FROM 10KTS TO PROBABLY 15G25KTS...ALL
OUT OF THE WNW.  BLUSTERY DAY WILL BE ON TAP...AND EVEN A FEW SNOW
FLAKES ACROSS THE NORTHERN SITES...WHICH WILL BE ADDRESSED IN THE
NEXT TAF CYCLE.

NOTICE...KEET TAF WILL HAVE (AMD LTD TO VIS WIND AND WX) AMENDED TO
THE END OF THE FORECAST THROUGH THE END OF 2010. THE CEILOMETER DATA
WILL BE GOING THROUGH NUMEROUS TESTS AND MONITORED FOR ACCURACY.
