.UPDATE...
/1135 AM CST WED JAN 6 2010/

WILL BE SENDING OUT A ZONE UPDATE SHORTLY TO FINE-TUNE THE ONSET
OF THE SNOW FOR THIS AFTERNOON AND EARLY THIS EVENING. OTHERWISE...12Z
SHORT-RANGE RUNS ARE SUPPORTING GOING FORECAST TRENDS FOR UPCOMING
STORM AND ARE STILL LOOKING QUITE GOOD. MAY NEED TO MAKE SOME
MINOR TWEEKS LATER THIS AFTERNOON BUT CERTAINLY THE MAJOR STORM
EMPHASIS CONTINUES TO BE TWO-FOLD...FIRST FOR THE FALLING
SNOW...THEN FOR THE INCREASING NORTHWEST WINDS PRODUCING BLOWING
AND DRIFTING...AND DANGEROUS WIND CHILLS.

.DISCUSSION...
/353 AM CST WED JAN 6 2010/

CLOUDS WILL INCREASE TDA AS SFC RDG OVER THE CWA SHIFTS E OF THE
AREA AND MID-UPR LEVEL TROF OVER THE NRN ROCKYS DROPS SEWD INTO THE
NRN PLAINS.  EVEN WITH INCREASING CLOUD COVER MAX TEMPS SHOULD BE A
COUPLE OF DGRS WARMER THAN YESTERDAY.  SNOW WILL SPREAD SEWD INTO
PTNS OF CNTRL AND NERN MO THIS AFTN AS MID LEVEL TROF CLOSES OFF
OVER ERN SD. THE MODELS DEPICT ISENTROPIC LIFT AT 295 K SHIFTING
E INTO THE CWA THIS AFTN ALTHOUGH MIXING RATIOS ARE NO MORE THAN
2-3 G/KG. THE SNOW WILL OVERSPREAD MOST OF THE CWA THIS EVNG AS
UPPER LEVEL DIVERGENCE INCREASES OVER THE AREA IN THE LEFT EXIT
REGION OF AN ULJ STREAK MOVG SEWD THRU THE PLAINS INTO SRN MO IN
THE BASE OF THE UPPER LEVEL TROF. THE MID LVL LOW WILL DROP SEWD
TO THE MO IA BORDER BY 12Z THU AND THEN DEEPEN AS IT MOVES EWD
THRU NERN MO AND CNTRL IL ON THU. THERE WILL BE PLENTY OF BROAD
SCALE SYNOPTIC LIFT OVER THE CWA LATE TGT AND THU MRNG AHEAD OF
THIS MID LVL LOW AND THE ASSOCIATED STRONG VORT MAX JUST SE OF THE
LOW CENTER. WITH BELOW FREEZING GROUND...SFC AND ROAD TEMPS THE
SNOW WILL RAPIDLY ACCUMULATE AFTER THE ONSET OF SNOWFALL AND ROADS
WHICH ARE NOT WELL TREATED WILL BECOME VERY SLICK CREATING VERY
HAZARDOUS DRIVING CONDITIONS ESPECIALLY FOR THE MORNING RUSH HOUR
ON THU. THE SNOW SHOULD TAPER OFF FROM W-SW TO E-NE AS THE DRY
SLOT MOVES EWD INTO THE CWA SW OF THE MID LVL LOW. DEFORMATION
TYPE SNOW MAY CONTINUE OVER THE NERN PTN OF THE CWA ON THU.
BLOWING AND DRIFTING SNOW IS EXPECTED ON THU AS THE SFC WINDS PICK
UP AND BECOME GUSTY AS THE SFC PRESSURE GRADIENT TIGHTENS AS THE
WEAK SFC LOW MOVES EWD THRU SRN IL WHILE A STRONG RIDGE OF HIGH
PRESSURE BUILDS SEWD INTO MO FROM THE NRN ROCKYS AND NRN PLAINS
REGION. WITH LOW LVL CLOUD COVER...AT LEAST LINGERING SNOWFALL AND
THE ARCTIC AIR MASS BUILDING SEWD INTO THE CWA TEMPERATURES
SHOULD BE FAIRLY STEADY DURING THE DAY ON THU. WITH THE SNOW
EXPECTED MAINLY TGT AND BLOWING SNOW ON THU HAVE UPGRADED THE
WINTER STORM WATCH TO A WINTER STORM WARNING ALONG AND NORTH OF A
LINE FROM COLUMBIA TO ST LOUIS TO JUST N OF SALEM ILLINOIS WHERE
TOTAL SNOW ACCUMULATION OF 4-6 INCHES IS EXPECTED...AND TO A
WINTER WEATHER ADVISORY OVER THE SRN PTN OF THE CWA WHERE 3-5
INCHES IS EXPECTED. ONLY SNOW SHOWERS OR FLURRIES ARE EXPECTED THU
NGT AND FRI WITH CYCLONIC MID-UPR LVL FLOW OVER THE AREA ALONG
WITH COLD MID LEVEL TEMPS. MORE SIGNIFICANT FOR THIS TIME PERIOD WILL
BE THE COLD WINDS CHILLS EXPECTED THU NGT AND FRI AND THE BITTERLY COLD
TEMPS FRI NGT. WILL LIKELY NEED TO ISSUE WIND CHILL ADVISORIES FOR
BOTH THU NGT AND FRI NGT.
