SPECIAL WEATHER STATEMENT
Issue Date: 507 AM CST TUE DEC 01 2009
Expiration: 500 PM CST TUE DEC 01 2009

...FIRST ACCUMULATING SNOW OF THE SEASON APPEARS LIKELY OVER
PARTS OF EASTERN AND CENTRAL MISSOURI AND SOUTHWEST ILLINOIS FOR
WEDNESDAY AFTERNOON AND NIGHT...
THE LATEST WEATHER DATA CONTINUES TO INDICATE THE POTENTIAL OF
ACCUMULATING SNOW ACROSS THE AREA FOR WEDNESDAY AFTERNOON AND
EVENING. THE MOST FAVORED REGION AT THIS TIME APPEARS TO BE FROM
THE ST LOUIS METRO AREA SOUTH TO AROUND FARMINGTON AND EAST TO
NEAR SALEM ILLINOIS...HOWEVER ALL AREAS IN EASTERN AND CENTRAL
MISSOURI AND SOUTHERN ILLINOIS APPEAR LIKELY TO GET AT LEAST A
LITTLE SNOW ACCUMULATION.
PRECIPITATION IS EXPECTED TO BEGIN AS LIGHT RAIN WEDNESDAY MORNING
OVER MUCH OF THE AREA BEFORE GRADUALLY INCREASING IN INTENSITY
HEADING INTO WEDNESDAY AFTERNOON. COLDER AIR SPILLING INTO THE
REGION FROM THE NORTHWEST WILL HELP CHANGE THE RAIN OVER TO SNOW
OVER MANY AREAS IN MISSOURI DURING WEDNESDAY AFTERNOON AND EARLY
WEDNESDAY EVENING IN ILLINOIS.
BY LATE WEDNESDAY NIGHT...SOME AREAS MAY HAVE PICKED UP A TOTAL OF
AN INCH OR TWO OF SNOW ACCUMULATION BEFORE THE SNOW TAPERS OFF TO
FLURRIES.
IT MUST BE STRESSED THAT THERE IS STILL SOME UNCERTAINTY WITH
REGARDS TO THIS STORM...ESPECIALLY WITH RESPECT TO HOW QUICKLY THE
COLD AIR WILL BUILD IN TO CHANGE THE PRECIPITATION OVER TO SNOW
AND ALSO WITH THE EXACT TRACK OF THE STORM. ANY CHANGE TO THESE
TWO ITEMS COULD DRASTICALLY IMPACT THE EXPECTED SNOWFALL AMOUNTS.
STAY TUNED TO NOAA WEATHER RADIO OR YOUR LOCAL MEDIA FOR FURTHER
DETAILS OR UPDATES ON THIS DEVELOPING WINTER STORM.
