THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF EAST CENTRAL
WISCONSIN...SOUTH CENTRAL WISCONSIN AND SOUTHEAST WISCONSIN.
.DAY ONE...TODAY AND TONIGHT
LIGHT SNOW WILL TAPER OFF THIS MORNING TO OCCASIONAL LIGHT SNOW
AND FLURRIES. TOTAL ACCUMULATIONS OF 1 TO 3 INCHES ARE EXPECTED
SOUTH OF A LINE FROM THE WISCONSIN DELLS TO THE MILWAUKEE AREA...WITH
THE HIGHEST AMOUNTS SOUTH AND WEST OF MADISON.
.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY
A COMPLEX STORM SYSTEM WILL FORM OVER THE SOUTHERN PLAINS BY
WEDNESDAY AND TRACK SLOWLY NORTH INTO THE GREAT LAKES REGION ON
CHRISTMAS.
AT THIS TIME...THE EXPECTED TRACK OF THE STORM SYSTEM WILL TAKE
IT FROM EASTERN IOWA ACROSS WESTERN WISCONSIN INTO UPPER MICHIGAN
BY FRIDAY NIGHT.
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 LATE WEDNESDAY NIGHT THROUGH
THURSDAY WHEN A SURGE OF WARM AIR JUST OFF THE SURFACE AHEAD OF
THIS STORM SYSTEM WILL CREATE THE BEST CHANCE FOR A PERIOD OF
FREEZING RAIN...SNOW AND SLEET. THERE IS A POTENTIAL THAT ICE
ACCUMULATION COULD REACH ONE TENTH TO ONE QUARTER INCH CAUSING A
MORE SIGNIFICANT IMPACT ON THURSDAY.
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
WEDNESDAY NIGHT INTO THURSDAY MORNING...AND THEN AGAIN THURSDAY NIGHT
AND FRIDAY AS COLDER AIR POURS BACK INTO THE REGION.
HOLIDAY TRAVEL IS LIKELY TO BE IMPACTED. GIVEN THE LARGE COMPLEXITY
OF THIS STORM SYSTEM...ADJUSTMENTS TO THE FORECAST ARE STILL
LIKELY. STAY ABREAST OF THE LATEST FORECAST CONCERNING THIS
EXPECTED WINTER STORM FOR THE UPCOMING HOLIDAY PERIOD.
.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION WILL NOT BE NEEDED BUT SNOWFALL REPORTS ARE
APPRECIATED THIS MORNING.
