AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 541 PM EST SUN FEB 14 2010 .AVIATION...DISCUSSION FOR 15/00Z TAFS. LATE THIS AFTERNOON OVERUNNING SNOWS RESIDED JUST SOUTH OF BMG AND HUF. THIS AREA OF SNOW WILL MOVE EAST AS THE EVENING GOES ON AND WILL NOT BE A CONCERN. MEANWHILE...AREA OF SNOW MOVING INTO STL AHEAD OF THE UPPER LOW PRESSURE CENTER JUST SOUTH OF KANSAS CITY IS EXPECTED TO EXPAND NORTHWARD A BIT AS IT MOVES SOUTHEAST AND THEN EAST TO THE NORTH OF THE UPPER LOW CENTER.

DO NOT FEEL THAT SOUTHWEST PORTIONS OF AREA WILL SEE QUITE AS MUCH ACCUMULATION AS EARLIER MODEL RUNS SUGGESTED DUE TO HOW QUICKLY THE CENTER OF LOW MOVES THROUGH...AND THE FACT THAT BEST ISENTROPIC LIFT CUTS OFF BY MON 12Z. HOWEVER...ISENTROPIC LIFT WILL LINGER ACROSS THE SOUTHEAST/EAST CENTRAL PORTIONS OF FORECAST AREA WELL INTO MONDAY AFTERNOON. ALSO...THE TRACK OF 700MB LOW AND DECENT TROWAL AT 925 MB MAKE THOSE AREAS THE MOST PRONE TO HEAVY ACCUMULATIONS....GOING WITH AMOUNTS OF 5 TO 7 INCHES. CONFIDENCE IS HIGH IN THOSE AMOUNTS. HOWEVER...WENT BACK AND FORTH ON WHETHER TO PUT RANDOLPH COUNTY IN ADVISORY OR WARNING...ENDED UP IN THE ADVISORY CRITERIA FOR NOW. ELSEWHERE...ANTICIPATE 3 TO 5 INCHES ACROSS NORTHERN PORTIONS OF WARNING AREA...AND 1 TO 3 INCHES IN ADVISORY AREA. INDY METRO IS IN ADVISORY AREA. TIMING...HEAVIEST SNOW WILL FALL ACROSS SOUTHWEST PORTIONS OF FORECAST AREA FROM MON00Z TO 06Z...WHILE THE BULK OF THE AREA WILL PICK UP ITS SNOW DURING THE OVERNIGHT HOURS. SO...TRAVEL CONDITIONS WILLL BE HAZARDOUS DURING MONDAY MORNING COMMUTE. SNOW SHOULD GRADUALLY TAPER OFF ACROSS EAST CENTRAL INDIANA BY MID DAY MONDAY. NORTHWEST WINDS WILL NOT BE AS BAD AS THEY WERE WITH THE LAST STORM THAT WENT THROUGH CENTRAL INDIANA. SUSTAINED SPEEDS WILL RANGE BETWEEN 5 TO 15 MPH WITH GUSTS UP TO 25 MPH ON MONDAY AFTERNOON/EVENING. TEMPS...MODELS IN GOOD AGREEMENT FOR TONIGHT AND TOMORROW...SO WENT WITH A BLEND. HOWEVER...TRENDED ABOVE GUIDANCE FOR TOMORROW NIGHT DUE TO CLOUD COVER AND WARM SECTOR OF STORM. .LONG TERM... AS FOR THE EXTENDED...PERSISTANT NORTHWEST FLOW IE EXPECTED ON WEDNESDAY THROUGH FRIDAY BEFORE THE ECMWF AND GFS HINT AT A MORE ZONAL FLOW OR PERHAPS SOME RIDGING FOR NEXTY FRIDAY...SATURDAY...AND SUNDAY. GFS AND ECMWF DISAGREE REGARDING A POSSIBLE SHORT WAVE ON FRIDAY INTO SATURDAY. GIVEN THE COLD NORTHWEST TO ZONAL FLOW AND LITTLE IN THE WAY OF MOISTURE ADVECTION WILL STICK WITH A DRY FORECAST UNTIL MORE AGREEMENT OR A STRONGER SIGNAL APPEARS. WILL CONTINUE TO TREND TEMPERATURES COLDER THAN THE MEXMOS GIVEN THE SNOW PACK AND CONTINUED NORTHWEST FLOW. && .PREV DISCUSSION... /ISSUED 1215 PM EST SUN FEB 14 2010/ AVIATION...DISCUSSION FOR THE 18Z TAFS. OVERVIEW...VFR/MVFR CONDITIONS EARLY THIS AFTERNOON ARE EXPECTED TO DETERIORATE TO IFR OR WORSE CONDITIONS THROUGH THE TAF PERIOD.
