NE WINDS 10-15 KTS TO SWITCH TO THE NW AFT 03Z AND INCRS TO 15-20 WITH GUSTS TO NEAR 30 KTS. && .DISCUSSION... FORECAST FOCUS IS ON WINTER STORM INTO TOMORROW. AT 08Z UPPER TROF WAS ACROSS PLAINS STATES WITH SW FLOW ALOFT ACROSS THE FORECAST AREA /FA/. PRECIP WAS ACROSS MUCH OF THE AREA FM SW IL/WRN KY TO AR AND TX. SNOW WAS ACROSS IL WITH QUICK TRANSITION TO RAIN IN KY. TEMPERATURES ACROSS THE FA WERE AROUND 30 DEGREES AND NEAR 32 IN THE FAR SW. MODELS ARE SIMILAR WITH MAJOR FIELDS. NAM IS STILL FARTHEST NW WITH SFC LOW TRACK. GFS/ECMWF/UKMET NOT AS FAR NW. WILL CONTINUE TO LEAN TOWARD GFS/ECMWF...BUT CANNOT COMPLETELY RULE OUT NAM AS IT HAS CAPTURED SOME PREVIOUS BIG STORMS BETTER THAN GFS AT THIS STAGE. FIRST ROUND OF PRECIPITATION WILL MOVE ACROSS THE FA THIS MORNING AS STRONG WARM ADVECTION KICKS IN. LOOKS LIKE SNOW WILL FALL ACROSS NRN 2/3 OF THE FA THIS MORNING WITH A MIX IN THE FAR SOUTH. TEMPERATURES ACROSS FAR SOUTH WILL BE CRITICAL THIS MORNING...AND EVEN A COUPLE OF DEGREE CHANGE MAY LEAD TO BIG CHANGE IN SNOW AMOUNTS DURING THE MORNING. IF PRECIP FALLS AS SNOW COULD BE A QUICK COUPLE OF INCHES ACROSS SWRN FA AS HEAVIER PRECIP MOVES IN. HAVE OPTED THIS ROUTE FOR NOW BASED ON OBSERVED NE WINDS WHICH SHOULD HELP KEEP TEMPS DOWN. AS THE PRECIP MOVES NE INTO THE COLDER AIR A COUPLE OF INCHES WILL FALL ELSEWHERE ACROSS THE FA. BY THIS AFTERNOON A DRY SLOT ALOFT WORKS IN...ENDS ICE CRYSTAL PRODUCTION ALOFT...AND WILL THUS HELP TURN PRECIP INTO SOME FZRA ACROSS SERN HALF OF FA. FAR SOUTHERN FA WILL SEE SOME RAIN AS TEMPERATURES CLIMB ABOVE FREEZING. THIS WILL KEEP SNOW AMOUNTS LOW THIS AFTN. DURING THE EVENING A WARM LAYER ALOFT WILL KEEP PRECIPITATION AS A MIX OF FZRA AND SN ACROSS SERN FA WITH SNOW EXPECTED ELSEWHERE. STRONG FRONTOGENESIS IN DEFORMATION ZONE WILL DEVELOP ACROSS NRN/WRN FA OVERNIGHT. Q VECTORS ALSO INDICATE PLENTY OF FORCING FOR LIFT ACROSS THE FA. OVERNIGHT COLDER AIR WILL WORK IN AND CHANGE ALL PRECIP TO SNOW. WITH PLENTY OF MOISTURE AVAILABLE...EXPECT DECENT SNOWFALL AMOUNTS. WINDS WILL BEGIN TO INCREASE DURING THE NIGHT AS SFC LOW DEEPENS. THUS BLOWING AND DRIFTING WILL APPEAR AS WELL. DEFORMATION ZONE WILL STILL BE ACROSS FA SUNDAY MORNING...MAINLY ACROSS NERN FA. THIS WILL DROP ANOTHER COUPLE OF INCHES BEFORE IT EXITS BY AFTN ENDING THE SNOW. TIGHT PRESSURE GRADIENT WILL LEAD TO WIND GUSTS AROUND 40 MPH...CONTINUING THE BLOWING AND DRIFTING PROBLEM. ALL IN ALL MUCH OF THE FORECAST REMAINS THE SAME AS PREVIOUS. EXPECT 6 TO 10 INCHES NORTH AND 4 TO 8 INCHES CENTRAL. DUE TO POSSIBLE ACCUMULATION THIS MORNING HAVE UPPED SRN FA TO A LITTLE TO THE 3 TO 6 INCH RANGE. IF MORNING PRECIP DOES NOT REMAIN SNOW FOR LONG...THIS FORECAST WILL BE OVERDONE. WILL HAVE TO KEEP A CLOSE EYE ON THE SOUTH. ANY ICE ACCUMULATIONS THIS AFTN LOOK TO BE LESS THAN A QUARTER OF AN INCH. THE COMBINATION OF THE SNOW...ICE...AND STRONG WINDS ON SUNDAY SUPPORT THE CURRENT WINTER STORM WARNING SETUP. AS FOR TEMPS WENT AT OR COOLER THAN MOS TODAY DUE TO CLOUDS/PRECIP AND NEAR MOS TONIGHT/SUNDAY. && .AVIATION...DISCUSSION FOR 06Z TAFS. SIGNIFICANT WINTER STORM TO IMPACT INDIANA BEGINNING AFTER 12Z.
