.PREV DISCUSSION... /ISSUED 222 PM CST FRI DEC 25 2009/ 

DISCUSSION...
RELATIVELY QUIET FORECAST IN THE WAKE OF YESTERDAY BLIZZARD. SUNNY
SKIES ATOP TO AREA TODAY...ALTHOUGH CONTINUED BREEZY CONDITIONS
KEEPING BLOWING SNOW A MINOR CONCERN ACROSS PORTIONS OF NORTHEAST
OKLAHOMA. VISIBILITIES ARE NOT LOW BY ANY STRETCH OF THE
IMAGINATION HOWEVER. TEMPERATURES BELOW FREEZING ACROSS ALMOST ALL
OF THE AREA...AND SHOULD REMAIN THAT WAY FOR SEVERAL DAYS.

VORT LOBE WILL ROTATE AROUND THE PERIPHERY OF MAIN UPPER LOW IN
IOWA...SOUTHWARD INTO NORTHERN OKLAHOMA AND NORTHWEST ARKANSAS
LATER TONIGHT. THIS WILL RESULT IN AN INCREASE IN LOW AND MID
CLOUD COVER LATE THIS AFTERNOON AND INTO THE EVENING...IN ADDITION
TO A CHANCE OF SOME FLURRIES MAINLY TO THE NORTH OF HIGHWAY 412
TOMORROW. CONTINUED NORTHERLY UPPER FLOW AND THE INFLUENCE OF THE
SNOW COVER WILL KEEP TEMPERATURES WELL BELOW NORMAL FOR THE NEXT
SEVERAL DAYS. MAV AND MET TEMPERATURES LOOKED TOO HIGH GIVEN THE
ABOVE REASONING /DESPITE THE WARMING INFLUENCE OF INCREASED CLOUD
COVER/ SO THE GENERAL TREND IS TO UNDERCUT THE GUIDANCE VALUES BY
SEVERAL DEGREES...ESPECIALLY ATOP THE SNOWPACK.

SOMEWHAT OF A WARMUP WILL COMMENCE FOR EARLY IN THE WORK WEEK
SOUTHWESTERLY UPPER FLOW RETURNS IN ADVANCE OF ANOTHER UPPER
SYSTEM. TEMPERATURES WILL STILL REMAIN COOL...BUT THE AREA SHOULD
WARM TO ABOVE FREEZING LEVELS.

PRECIP ENTERS THE FORECAST AGAIN FOR TUESDAY...WITH WINTRY
PRECIPITATION /LIKELY SNOW/ AGAIN POSSIBLE...ESPECIALLY FOR
NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS. THIS SYSTEM WILL NOT
COME CLOSE TO THE PUNCH OF THIS LAST ONE HOWEVER.

SURFACE HIGH WILL SETTLE INTO THE AREA BEHIND THIS
SYSTEM...BRINGING COLD TEMPERATURES ONCE AGAIN.
