AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE ST LOUIS MO
1204 AM CST WED FEB 2 2011

.UPDATE...
/900 PM CST TUE FEB 1 2011/

BLIZZARD HAS CAUSED BIG IMPACTS AS IT BEGINS TO LIFT OUT OF THE
AREA. I-70 REMAINS CLOSED WEST OF WENTZVILLE AND WE HAVE REPORTS
THAT SNOW PLOWS ARE BEING PULLED OFF THE ROADS IN ADAMS COUNTY IL.
SNOWFALL REPORTS INTO THE OFFICE ARE 15-20 INCHES FROM QUINCY TO
JEFFERSON CITY WITH UP TO 5 FOOT DRIFTS. SNOWFALL RATES WILL BEGIN
TO DIMINISH RAPIDLY IN THE NEXT FEW HOURS AS UPPER LOW LIFTS OUT
OF THE AREA...SO ONLY EXPECT ANOTHER 1-3 INCHES IN THIS AREA.

RADAR IS SHOWING AN ENHANCED BAND OF SNOW ENTERING THE WESTERN STL
METRO WHICH COULD PRODUCE ANOTHER QUICK 1 TO 2 INCHES OF SNOWFALL.
EXPECT LITTLE IF ANY ADDITIONAL MEASUREABLE PRECIPITATION OVER THE
SRN CWA AS LARGE SCALE SUBSIDENCE MOVES IN BEHIND THE UPPER LOW
TONIGHT.

WINDS ARE GUSTING BETWEEN 30-40KTS OVER SRN IA AND NRN MO WHICH
SHOULD SPREAD ACROSS THE CWA TONIGHT AS THE SURFACE MOVES EWD
TONIGHT. THERE MAY STILL BE AN INCREASE IN POWER OUTAGES AS THE
WINDS INCREASE AS IN AREAS THAT HAD BETWEEN 1/4-3/4 OF ICE
ACCUMULATIONS OVER THE SRN AND ERN COUNTIES.

WILL LEAVE HEADLINES THEY AREA. IMPACTS IN THE BLIZZARD WARNING
WILL CONTINUE THROUGH THE NIGHT WITH THE SIMILAR IMPACTS BECAUSE
OF THE ICE AND INCREASING WINDS IN THE WINTER STORM WARNING. NEW
FORECAST WILL BE OUT SHORTLY.

BRITT

.DISCUSSION...
/325 PM CST TUE FEB 1 2011/

CRIPPLING WINTER STORM IS WELL UNDERWAY WITH SNOWFALL TOTALS
REACHING 10-12 INCHES FROM MEXICO TO SOUTH OF JEFFERSON CITY AND
7 INCHES ALREADY UP NEAR QUINCY. INTERSTATE 70 HAS BEEN CLOSED IN
CENTRAL MISSOURI BECAUSE OF THE TREACHEROUS CONDITIONS. SNOWFALL
TOTALS FARTHER EAST HAVE NOT BEEN AS IMPRESSIVE AS THE SYSTEM
BROUGHT IN WARMER AIR IN THE ST. LOUIS METRO AREA KEEPING A MIX OF
SNOW AND SLEET THROUGH THE DAY...WITH MAINLY FREEZING RAIN OVER
THE SRN AND ERN PARTS OF THE CWA.

DRY SLOT HAS MOVED IN ACROSS THE SRN CWA CAUSING A TEMPORARY LULL
IN THE PRECIPITATION INTENSITIES. THIS DRY SLOT AS BEGUN TO FILL IN
AS SOUTHERN END OF THE DEFORMATION ZONE IS MOVING ACROSS SWRN MO
CAUSING MODERATE TO HEAVY SNOWFALL. RUC/HRRR IS PICKING UP ON THIS
PRETTY WELL WITH THE RUC BRINGING AND INTENSE BAND OF MID LEVEL
FRONTOGENESIS UP ALONG INTERSTATE 44 INTO EARLY EVENING. THIS
SHOULD BRING BRIEF 1-2 INCH SNOWFALL RATES ACROSS THE STL METRO
INTO EARLY EVENING. FARTHER NORTH...INTENSE ASCENT WITH THE TROUGH
WILL LIKELY TO CONTINUE TO CAUSE VERY HEAVY SNOWFALL OVER
CNTRL/NERN MO AND W CENTRAL IL THROUGH AT LEAST MID EVENING.
EXPECT THE ACCUMULATING SNOW TO DIMINISH RAPIDLY FROM SOUTHWEST
TO NORTHEAST TONIGHT AS THE TROUGH PASSES THROUGH THE AREA.

WINDS CONTINUE TO INCREASE AS THE SURFACE LOW NEAR THE BOOTHEEL
DEEPENS AS IT MOVES NORTHEAST. STILL EXPECT FREQUENT GUSTS TO 35
MPH IN THE BLIZZARD WARNING AS 925MB WINDS WILL BE CLOSE TO 50KTS.
THESE WINDS WILL CAUSE WIDESPREAD BLOWING AND DRIFTING SNOW WHERE
THERE IS DEEPER SNOW COVER.

STAYED ON THE COLDER SIDE OF TEMPERATURE GUIDANCE AS VERY COLD
AIRMASS WILL MOVE OVER FRESH SNOW COVER. WIND CHILLS ON WEDNESDAY
NIGHT WILL LIKELY FALL BELOW -20 OVER ACROSS THE DEEPEST SNOW
COVER...AND A WIND CHILL ADVISORY MAY NEED TO BE ISSUED FOR THIS
AREA BY LATER SHIFTS.

FOR LATE WEEK INTO EARLY NEXT WEEK...UPPER FLOW REMAINS AMPLIFIED
WITH A LARGE TROF DEVELOPING ACROSS THE EASTERN HALF OF THE
NATION. SEVERAL DISTURBANCES WILL RIPPLE ACROSS THE MIDDLE
MISSISSIPPI RIVER VALLEY PROVIDING A CHANCE OF SNOW THIS WEEKEND
AND EARLY NEXT WEEK. TEMPERATURES WILL MODERATE THIS WEEKEND...BUT
REMAIN BELOW AVERAGE...WITH ANOTHER VERY COLD AIRMASS PROGGED BY
THE GUIDANCE TO MOVE SOUTH FROM CANADA EARLY NEXT WEEK...WHICH
WILL DRIVE TEMPERATURES BACK WELL BELOW NORMAL.

BRITT/CVKING

.AVIATION...
/1201 AM CST WED FEB 2 2011/

LAST GASP OF SNOWFALL FROM THIS EARLY FEBRUARY RECORD BREAKER
...ROUGHLY CENTERED ON A IJX-UVV AXIS AT 0530Z...IS MOVING EAST AT
15 KTS. MUCH LIGHTER SNOWFALL IS OCCURRING WEST OF THIS BAND...BUT
IT APPEARS THAT THE VSBY RESTRICTIONS IN THIS AREA MAY BE LARGELY
A RESULT OF BLOWING SNOW RATHER THAN FALLING SNOW. HAVE CONTINUED
SOME MENTION OF BLOWING SNOW AT UIN AND COU INTO THE PREDAWN HOURS
AS THE STRONG NORTHWEST WINDS INTERACT WITH SNOWFALLS OF 15-20
INCHES. OVERALL TREND OF THE TAFS IS TO END THE VSBY RESTRICTIONS
OVER THE NEXT FEW HOURS....GO TO A PREDOMINATE MVFR CIG BETWEEN
2-3KFT WHICH SHOULD SCATTER OUT WED AFTERNOON.

SPECIFICS FOR KSTL...AFOREMENTIONED BAND OF SNOW SHOULD TAPER OFF
TO FLURRIES NO LATER THAN 08Z. ALTHOUGH CIGS IN THE STL METRO AREA
ARE STILL MVFR HAVE CARRIED IFR WITH THIS SOMEWHAT HEAVIER SNOW TO
REFLECT TRENDS AT UVV AND M06. ONCE SNOW ENDS MVFR CIGS SHOULD
DOMINATE REMAINDER OF THE NIGHT AND MOST OF THE DAY ON WED...WITH
2-3KFT DECK SCATTERING OUT BY SUNSET.
