AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BIRMINGHAM AL 1156 PM CST SAT DEC 31 2011 .UPDATE... 06Z AVIATION. && .DISCUSSION... HAPPY NEW YEAR FROM YOUR NATIONAL WEATHER SERVICE. THE FORECAST TREND OVERNIGHT IS IN GOOD SHAPE BUT MADE SOME FINE SCALE ADJUSTMENTS TO TEMPS AND DEW POINTS. ADDED MENTION OF PATCHY DENSE FOG FAR SOUTH. ALSO INCREASED WINDS JUST A TAD ON SUNDAY...15 TO 25 MPH WITH A FEW HIGHER GUSTS BUT BELOW WIND ADVISORY CRITERIA. SURFACE LOW OVER SOUTHERN IOWA AND ASSOCIATED SURFACE COLD FRONT THROUGH MISSOURI AND INTO WESTERN ARKANSAS AND CENTRAL TEXAS. THE SYSTEM IS REALLY CHUGGING ALONG BUT THINK THE TIMING WILL BE A BIT CLOSER TO THE SLIGHTLY SLOWER NAM. RULE OF THUMB ABOUT 12 HOURS FROM LITTLE ROCK BUT THIS SYSTEM IS MOVING. VERY STRONG PRESSURE GRADIENT ALONG THE FRONT PRODUCING PLENTY OF WIND GUSTS THIS EVENING. MODEL CONSENSUS INDICATES SOUTHERLY WINDS INCREASING TO 30-45KTS JUST ABOVE THE SURFACE AFTER 06Z...AND LASTING THROUGH AROUND 14Z. DO NOT THINK ANY MIXING WILL OCCUR..SO KEPT THE WINDS BELOW ADVISORY CRITERIA AT THIS TIME. FOR THE OVERNIGHT HOURS...SURFACE DEW POINTS INCREASING RAPIDLY ACROSS MISSISSIPPI AND SEA FOG NEAR COASTAL ALABAMA AND THE FLORIDA PANHANDLE. THESE MOISTURE AXIS WILL SLOWLY ENCROACH ON CENTRAL ALABAMA AND BY SUNRISE...DEW POINTS INTO THE 50S FOR MUCH OF THE SOUTHWESTERN TWO THIRDS OF THE AREA. THE MAIN CONCERN HERE IS...WILL DENSE FOG DEVELOP. I THINK THE BEST CHANCE AT DEVELOPMENT WILL BE SOUTHEAST NEAR TOI WHERE TEMPS HAVE DIPPED INTO THE 40S AND DEW POINTS ARE RISING. WINDS WOULD PICK UP HOPEFULLY JUST ENOUGH TO PREVENT MORE WIDESPREAD DEVELOPMENT AS FAR NORTH AS TCL-BHM BY SUNRISE. THERE IS PLENTY OF ISENTROPIC LIFT AHEAD OF THE FRONT AND IN THE WAA REGIME AND CLOUD DEVELOPMENT WILL BE WIDESPREAD. WILL KEEP POPS AS IS WITH SCATTERED LIGHT TO ISOLATED SHOWERS. REALLY DO NO SEE MUCH ADDING UP DUE TO THE LIMITED DEPTH OF THE MOISTURE AVAILABLE. 75 && .AVIATION... 06Z TAF DISCUSSION. LOTS TO TALK ABOUT TONIGHT...SO LET'S GET RIGHT TO IT. OVERALL EXPECT CONDITIONS TO DETERIORATE THRU THE NIGHT. A SURGE OF LOW LEVEL MOISTURE AND ISENTROPIC LIFT IS TO BLAME FOR THE LOW STRATUS DECK OVER MS...WHICH WILL SPREAD NORTHEASTWARD ACROSS THE CWA OVERNIGHT BRINGING CIGS DOWN TO MVFR AND THEN IFR. WAA AND QUICKLY COOLING TEMPS IN THE SOUTHEAST COULD LEAD TO SOME PATCHY DENSE FOG...ESPECIALLY AT TOI. OBS TO THE SOUTH ARE SHOWING 1/4 MI VIS AND 200 FT CIGS. NOT SURE IF THOSE PREVAILING LIFR CONDITIONS WILL MAKE IT AS FAR NORTH AS TOI...BUT DID KEEP A TEMPO IN FOR LIFR AT TOI EARLY TOMORROW MORNING. WILL HAVE TO WATCH THE NORTHWARD PROGRESSION OF THE DENSE FOG CLOSELY AND MAKE AMENDMENTS IF NECESSARY. A FEW LIGHT SHOWERS ARE POSSIBLE OUT AHEAD OF THE FRONT AS IT MOVES THRU...BUT COVERAGE WILL JUST BE TOO LOW TO MENTION IN THE TAFS. MODELS INDICATE WINDS AT 2000 FT WILL BE OUT OF THE SW AROUND 35-45 KTS AHEAD OF THE FRONT...MAINLY BETWEEN 08Z AND 12Z...WHICH COULD LEAD TO SOME WIND SHEAR AT ALL TERMINALS. WIND SHEAR CONCERNS WILL DIMINISH AS THE FRONT PASSES. SFC WINDS WILL SHIFT TO THE WNW BEHIND THE FRONT GUSTING UP TO 25 KTS. SINCE MOST OF THE WEATHER IMPACTS WILL OCCUR IN THE NEXT 12 HRS DID NOT WORRY ABOUT ADDING LINES FOR CLEARING SKIES AND DECREASING WINDS SUNDAY EVENING. 19 && .PRELIMINARY POINT TEMPS/POPS...
