NWS Huntsville, AL wrote its last area forecast discussion before the first event at Dec 9, 11:46 PM CST, 4 hours 14 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE HUNTSVILLE AL 1146 PM CST MON DEC 9 2013 .UPDATE... FOR 06Z TAFS && .DISCUSSION... /ISSUED 951 PM CST MON DEC 9 2013/ THE MUCH PROMISED RAIN HAS REACHED THE REGION AS OF THIS WRITING. ALONG WITH THE RAIN...AN AREA OF UPPER LEVEL SUPPORT HAS LED TO THE DEVELOPMENT OF EMBEDDED THUNDERSTORMS (NOW NEARING THE JACKSON/ DEKALB AND GEORGIA BORDER). OTHER EMBEDDED STORMS WERE NOTED OVER CENTRAL MISSISSIPPI...WITH ONE MOVING ACROSS THE KGWX DOPPLER RADAR. IF THIS ONE MAINTAINS COURSE...IT COULD AFFECT PARTS OF THE HUNTSVILLE AREA IN THE NEXT 1-2 HOURS...AS IT TRACKS TO THE NE 65-70 MPH. OTHERWISE...THE FORECAST FOR THE OVERNIGHT IS ON TRACK...AS ANOTHER SHOT OF COLDER AIR CONTINUES FILTERING SOUTHWARD ACROSS THIS PART OF THE TENNESSEE VALLEY. 9 PM TEMPERATURES RANGED FROM NEAR/BELOW FREEZING JUST TO THE WEST/NORTH OF OUR FORECAST AREA...WITH MID 30S IN OUR MIDDLE REGION...AND READINGS IN THE UPPER 30S TO AS WARM AS THE MID 40S AT FT PAYNE. GIVEN A TRACK OF PRECIPITATION MOVING TO THE NE FROM MS AND THE COLD AIR SEEPING IN FROM THE NORTH...A CHANGE OVER TO A MIX OF RAIN/FREEZING RAIN/AND SOME SLEET WILL OCCUR MAINLY AROUND AND AFTER MIDNIGHT. HOW MUCH PRECIP FALLS...AND HOW COLD WILL IT GET BEFORE IT MOVES OUT OF THE AREA ARE THE BIG QUESTIONS EVEN WITH NEW DATA COMING IN. CURRENT THINKING IS THAT A RELATIVELY WARM GROUND SHOULD FOR THE MOST PART HELP TO MINIMIZE ICING ON MOST GROUND SURFACES. HOWEVER...CANNOT SAY THE SAME FOR ELEVATED SURFACES. A FEW HOURS OF AT/BELOW FREEZING TEMPERATURES AND THIS PRECIP COULD CAUSE ICING ISSUES DURING THE LATE NIGHT AND AROUND DAYBREAK...WITH BRIDGES/ OVERPASSES MORE SUBJECT TO ICING. TOTAL ICE ACCUMULATIONS ARE EXPECTED TO REMAIN BELOW 1/10 OF AN INCH...BUT EVEN A SLIGHT GLAZE ON A TRAVEL SURFACE COULD BECOME POTENTIALLY DANGEROUS. OUTPUT FROM THE NEW NAM WAS IN GENERALLY GOOD AGREEMENT WITH ITS OLDER RUNS AND THE GFS. THUS THE PRECIP SHOULD END AROUND DAYBREAK FROM SW TO NE. THE SUN RETURNING TOMORROW AND EVAPORATION SHOULD HOPEFULLY HELP END THE ICING PROBLEM BY THE LATE MORNING. RSB && .AVIATION... FOR 06Z TAFS... INCLEMENT FLYING WEATHER WILL CONTINUE INTO TUE AM...AS AN UPPER LEVEL DISTURBANCES TRACKS ACROSS THE AREA FROM THE SW. COLDER AIR FILTERING IN FROM THE NORTH WILL CAUSE A MIX/CHANGE OVER FROM RAIN TO A WINTRY MIX OF FREEZING RAIN/RAIN/SNOW. THE MAJORITY OF THE PCPN BY THE LATE NIGHT SHOULD BE -FZRA...WITH LIGHT ICE ACCUMULATIONS POSSIBLE ON ELEVATED SURFACES. THE PCPN SHOULD END SHORTLY AFTER DAYBREAK...WITH VFR WEATHER RETURNING BY THE LATE MORNING. NORTH WINDS IN THE 5-10 KT RANGE FOR MUCH OF THE PERIOD WILL BECOME LIGHT AND VARIABLE AFTER DUSK LATE TUE AFTERNOON. RSB && .HUN WATCHES/WARNINGS/ADVISORIES... AL...WINTER WEATHER ADVISORY UNTIL 9 AM CST TUESDAY FOR ALZ001>007-009.
