AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HUNTSVILLE AL
1107 PM CST SUN FEB 14 2010
.UPDATE...
EVENING FORECAST UPDATE AND 06Z AVIATION DISCUSSION.
&&
.DISCUSSION...
MESOSCALE UPDATE...TEMPERATURES ARE FINALLY DROPPING OVER NWRN
ALABAMA...SOLIDLY IN THE UPPER 30S EVERYWHERE AND DECREASING AT A
FAIR CLIP. TEMP IS BELOW FREEZING AT SAVANNAH TN...SO IT MAY NOT BE
MUCH LONGER BEFORE THE CHANGEOVER OCCURS HERE IN ALABAMA. IN
FACT...JUST GOT A REPORT OF -SN MXIING WITH -RA IN THE FAR WESTERN
COUNTIES...AND VISBY AT CORINTH IS 2SM WHICH IMPLIES SNOW. SO
EVERYTHING STILL LOOKS TO BE ON TRACK TIMINGWISE. HOWEVER...IT
APPEARS THE ZONE OF ENHANCEMENT IS SETTING UP FURTHER EAST...AND
THIS MAY LIMIT ACCUMULATIONS SOMEWHAT BACK TO THE WEST. GROUND TRUTH
OUT OF THE MEMPHIS METRO HAS BEEN MAINLY 1/2 TO 1 INCH. AREAS NEAR
THE AL/MS BORDER APPEAR TO GET THE LEAST SNOW ACCUMULATION UNLESS
SOME ENHANCEMENT OCCURS PRETTY SOON. BROADENED THE SNOW RANGE TO 1
TO 3 INCHES TO COVER A LOWER POTENTIAL IN THE WEST.
MOVING FURTHER EAST...RAIN HAS SPREAD IN WITH ENOUGH CONVECTIVE
INSTABILITY THAT WE HAVE SEEN SOME ISOLATED THUNDERSTORMS TO THE
SOUTH OF THE TENNESSEE VALLEY. WILL BE INTERESTING TO SEE HOW THE
DIFLUENCE AND INSTABILITY FURTHER EAST WILL AFFECT THE PRECIP BAND
TO THE WEST AS IT MOVES IN. NOTE THE MESOSCALE DISCUSSION FOR HEAVY
SNOW RATES ISSUED BY SPC EARLIER. AT THIS POINT...EVERYTHING STILL
LOOKS ON TARGET FOR THE EAST...AND IF THERE IS SOME CONVECTIVE
ENHANCEMENT...SOME SNOWFALL TOTALS OVER 4 INCHES MAY OCCUR...
ESPECIALLY AT HIGHER ELEVATIONS WHICH WILL EXPERIENCE LITTLE RAIN
BEFORE A CHANGEOVER. TIMING HAS NOT CHANGED SUBSTANTIALLY.
OTHER THAN THE 1-3 INCH MENTION OUT WEST...NO CHANGES WILL BE MADE
TO THE WINTER WEATHER PRODUCTS AT THIS POINT.
STILL WORTH NOTING...ALTHOUGH BEYOND THE CURRENT FORECAST PERIOD...
THE FORECAST MODELS ARE HONING IN ON A BRIEF SHOT OF -SN TOMORROW
AFTERNOON OR EARLY EVENING THAT MIGHT PROVIDE A LITTLE COATING ATOP
WHATEVER WE GET TONIGHT. WILL LET THE MIDSHIFT EXPLORE THAT
POSSIBILITY FURTHER BUT THOUGHT IT WAS WORTH A MENTION.
&&
.AVIATION.../06Z AVIATION DISCUSSION/
IFR VISBY/CIGS LIKELY TO PERSIST UNTIL THE PCPN COMES TO AN END LATE
TONIGHT. STILL APPEARS WE COULD GET BACK TO VFR CONDITIONS DURING
PART OF THE DAY. SOME CONVECTIVE SHSN ARE STILL POSSIBLE...
ESPECIALLY LATE IN THE AFTERNOON. WINDS WILL GET GUSTY JUST BEHIND
THE FROPA...AND THEN AGAIN DURING THE AFTERNOON IN PARTICULAR.
