THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF EAST CENTRAL
WISCONSIN...SOUTH CENTRAL WISCONSIN AND SOUTHEAST WISCONSIN.
.DAY ONE...TODAY AND TONIGHT
WEAK LOW PRESSURE IS EXPECTED TO MOVE ALONG A NEARLY STATIONARY
FRONTAL BOUNDARY DRAPED ACROSS NORTHERN ILLINOIS AND FAR SOUTHERN
WISCONSIN TONIGHT AND MONDAY MORNING. THIS SYSTEM WILL ALLOW SNOW
TO OVERSPREAD SOUTHERN WISCONSIN TONIGHT. ONE TO THREE INCHES OF
SNOW IS EXPECTED MOST AREAS BY SUNRISE MONDAY.
.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY
THE ACCUMULATING SNOW WILL TAPER OFF FROM WEST TO EAST ON MONDAY.
TOTAL SNOW ACCUMULATIONS OF 2 TO 4 INCHES ARE EXPECTED WITH A FEW
5 INCH SNOWFALLS. THE HEAVIEST SNOW IS EXPECTED FROM SHEBOYGAN
AND FOND DU LAC TO BEAVER DAM...WEST BEND...MADISON...BARABOO AND
SPRING GREEN. PLAN ON THE SNOW IMPACTING TRAVEL CONDITIONS MONDAY
MORNING.
A SECOND MUCH STRONGER LOW PRESSURE SYSTEM IS EXPECTED TO DEVELOP
IN THE SOUTHERN PLAINS ON TUESDAY...AND THEN TRACK NORTHEAST INTO
NORTHERN ILLINOIS AND INDIANA LATE TUESDAY NIGHT AND WEDNESDAY...
RESULTING IN ACCUMULATING SNOW ACROSS WISCONSIN.
THIS WEATHER SYSTEM WILL HAVE MUCH MORE ATMOSPHERIC DYNAMICS AND
MOISTURE TO WORK WITH...HENCE SIGNIFICANT SNOWFALL GREATER THAN 6
INCHES IS ANTICIPATED. IN ADDITION STRONG NORTHWEST WINDS ON
WEDNESDAY WILL RESULT IN SEVERE BLOWING SNOW...WHICH WOULD
SEVERELY RESTRICT THE VISIBILITY IN OPEN AREAS.
THERE IS STILL CONSIDERABLE UNCERTAINTY TO THE EXACT TRACK THIS
STORM SYSTEM WILL TAKE. SEVERAL OF THE LATEST COMPUTER FORECAST MODELS
ARE SHOWING A POTENTIAL FOR WARMER AIR SURGING INTO SOUTHEAST
WISCONSIN WHICH WOULD RESULT IN MORE OF A MIXTURE OF PRECIPITATION...WHICH
WOULD CUT DOWN ON SNOW AMOUNTS.
NEVER THE LESS...THIS WILL LIKELY BE THE FIRST MAJOR WINTER STORM
FOR THE UPPER MIDWEST THIS SEASON...AND WILL LIKELY HAVE A
SIGNIFICANT IMPACT ON SOCIETY. MONITOR THE LATEST FORECASTS ON
THIS DEVELOPING WINTER STORM...AND BE READY TO DELAY ANY TRAVEL PLANS
FOR WEDNESDAY.

APPRECIATED.
