HAZARDOUS WEATHER OUTLOOK
Issue Date: 925 PM CST MON DEC 21 2009
Expiration: 345 PM CST TUE DEC 22 2009
THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF EAST CENTRAL
WISCONSIN...SOUTH CENTRAL WISCONSIN AND SOUTHEAST WISCONSIN.
.DAY ONE...TONIGHT
LIGHT SNOW WILL AFFECT LOCATIONS MAINLY SOUTH OF A WISCONSIN
DELLS...TO WATERTOWN...TO MILWAUKEE LINE. SNOW ACCUMULATIONS OF ONE
HALF INCH TO NEAR 2 INCHES TOWARD SOUTHWEST WISCONSIN ARE EXPECTED
BY SUNRISE. SLIPPERY SPOTS ARE EXPECTED DURING THE MORNING RUSH
HOUR.
.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY
A COMPLEX STORM SYSTEM WILL FORM OVER THE SOUTHERN PLAINS BY
WEDNESDAY AND TRACK SLOWLY NORTH INTO THE GREAT LAKES REGION ON
CHRISTMAS. THE CURRENT FORECAST TRACK TAKES IT FROM SOUTHWEST
WISCONSIN INTO UPPER MICHIGAN. THIS IS A WARMER TRACK FOR SOUTHERN
WISCONSIN...AND IS ONE THAT WILL RESULT IN A WIDE VARIETY OF
WINTRY PRECIPITATION TYPES. THE MOST HAZARDOUS PERIOD LOOKS TO BE
WEDNESDAY NIGHT INTO THURSDAY...THE BEST CHANCE FOR A PERIOD OF
FREEZING RAIN AND SLEET. ADDITIONALLY...THERE IS THE THREAT FOR
ENOUGH RAIN TO FALL ON TOP OF THE CURRENT SNOW PACK TO RESULT IN
MINOR FLOODING OF AREA CREEKS...RIVERS...AND STREAMS. RUNOFF COULD
ALSO CAUSE PONDING OF WATER ON AREA ROADWAYS.
ANY ACCUMULATING SNOW SHOULD OCCUR AT THE BEGINNING OF THIS SYSTEM
ON WEDNESDAY...AND THEN AGAIN TOWARD THE END ON CHRISTMAS.
HOLIDAY TRAVEL IS LIKELY TO BE IMPACTED...ESPECIALLY FOR THOSE
HEADED NORTH AND WEST. GIVEN THE LARGE COMPLEXITY OF THIS STORM
SYSTEM...SIGNIFICANT ADJUSTMENTS TO THE FORECAST ARE STILL POSSIBLE.
.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION WILL NOT BE NEEDED.
