AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HUNTSVILLE AL 553 AM CST MON FEB 8 2010 .UPDATE...FOR 12Z TAFS && .AVIATION...5H TROF OVER THE SWRN US...HAS A WEAK DISTURBANCE AHEAD OF IT...THAT WAS MOVING ACROSS PORTIONS OF ERN TX/AR/WRN TN. THIS DISTURBANCE IS HEADING OUR WAY...HAD REPORTS THAT SNOW/SLEET WAS HITTING THE GROUND IN NE MS ATTM. WILL INCLUDE THIS IN THE MSL TAF. NOT SURE IF THIS NARROW BAND OF SLEET/SNOW WILL HOLD TOGETHER TO REACH HSV...SO WILL LEAVE OUT FOR NOW. MODEL SOUNDINGS SHOWS THAT BY THIS AFTN/TONIGHT THE ATMOSPHERE WILL BE WARM ENOUGH FOR ALL RAIN. WILL BRING IN A PROB30 GROUP FOR BOTH TAF SITES ARND 22Z THIS AFTN. BEST CHC OF RAIN WILL BE BETWEEN 05Z/06Z TONIGHT AND CONTINUING INTO TUESDAY MRNG. && .PREV DISCUSSION... /ISSUED 451 AM CST MON FEB 8 2010/ DISCUSSION... TODAY...CLOUDY CONDITIONS CONTINUE ACROSS MOST OF THE AREA. HOWEVER...SOME MOSTLY CLEAR TO PARTLY CLOUDY CONDITIONS SHOWING UP ON SATELLITE IMAGERY OVER MUCH OF LAUDERDALE COUNTY AND IN NORTHERN PORTIONS OF SOUTHERN MIDDLE TN. THIS WILL ALLOW TEMPERATURES TO BOTTOM OUT POSSIBLY IN THE UPPER 20S BY DAYBREAK IN THE LOCATIONS WHICH SEE THE MOST CLEARING. ELSEWHERE...TEMPERATURES AROUND DAYBREAK SHOULD BE BETWEEN 31 AND 33 DEGREES. MORE CLOUD COVER ON THE WAY...COURTESY OF A WEAK UPPER LEVEL DISTURBANCE OVER NW ARKANSAS MOVING THROUGH ZONAL FLOW. EARLY THIS MORNING...THERE COULD BE A MIX OF RAIN AND SNOW IN NORTHWESTERN ALABAMA. HOWEVER...DUE TO DRY AIR IN PLACE AND FORECAST WEAKENING OF THIS DISTURBANCE BY MODELS AS IT PUSHES EAST...NOT SURE HOW MUCH OF THIS WINTRY PRECIPITATION WILL MAKE IT TO THE GROUND. BY AFTERNOON HOURS...PRECIPITATION SHOULD ALL BE IN THE FORM OF RAIN AND SHOULD INCREASE IN INTENSITY...AS A STRONG UPPER LOW PUSHES A TRAILING COLD FRONT TOWARDS THE AREA. LOWERED TEMPERATURES DUE TO CURRENT CONDITIONS AND EXPECTED CLOUD COVER/PRECIPITATION. 1 TO 2 INCHES OF RAINFALL ACCUMULATION LOOKS POSSIBLE IN MOST LOCATIONS ACROSS THE FORECAST AREA THROUGH TUESDAY AFTERNOON. NORTHWEST ALABAMA SHOULD SEE AN END TO THE RAINFALL AROUND NOON ON TUESDAY. MUCH DRIER AIR IS PROGGED TO PUSH INTO THE AREA BEHIND THE FRONT LATE TUESDAY INTO TUESDAY NIGHT. THEREFORE ISOLATED FLURRIES WERE TAKEN OUT...DUE TO DRIER 00Z MODEL DATA. WEDNESDAY...THE UPPER LOW MOVES INTO THE NERN US TAKING PCPN WITH IT...AS WEAK SFC HIGH BUILDS ACROSS THE TN VALLEY. THURSDAY...REMOVED LIGHT SNOW FROM FCST FOR THURSDAY NIGHT BASED ON GFS/ECMWF MODEL SOUNDINGS SHOWING ATMOSPHERE LOOKS TO DRY ATTM. FRIDAY...A FAIRLY STRONG UPPER TROF WILL APPROACH THE CWA WITH A CHC OF SOME WINTER WX. HOWEVER...SFC LOW IS PROGGED ATTM TO MOVE ACROSS THE NRN GULF OF MEXICO...WHICH MAY KEEP MOST OF THE PCPN TO OUR SOUTH...BASED ON GFS. THE GFS SOUNDINGS/CRITICAL THICKNESS ALSO SHOW THAT TEMPS WILL BE COLD ENOUGH FOR ALL SNOW WITH THE BEST TIMING BETWEEN FRIDAY MORNING AND LATE AFTN. ON THE OTHER HAND ECMWF TIMING HAS THE PCPN COMING BETWEEN THE AFTN AND EVENING HOURS. ANOTHER PROBLEM WILL BE TEMPS ON FRIDAY...THINKING THAT GFS MOS MAY END UP BEING TO WARM...INSTEAD OF UPPER 30S COULD EASILY BE LOW/MID 30S WHICH WOULD BE COLD ENOUGH TO SUPPORT ALL SNOW. SINCE THERE IS A TIMING DIFFERENCE BETWEEN GFS AND ECMWF WITH THE SNOW...WILL TAKE A BLEND AND KEEP A LOW POP GOING FOR THE EVENING HOURS. ALL PCPN SHOULD BE OVER AFTER MIDNIGHT. AGAIN THIS TIMEFRAME IS A LITTLE TO FAR OUT IN THE FCST FOR ANY EXACT DETAILS...THUS CONFIDENCE IS NOT TO HIGH ATTM. SATURDAY/SUNDAY...SFC HIGH/UPPER NW FLOW SHOULD KEEP NEXT WEEKEND DRY BUT ON THE COLD SIDE...WITH MRNG LOWS IN THE LOWER 20S AND AFTN HIGHS IN THE LOW 40S. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE. TN...NONE. && 007
