.UPDATE...
ISSUED AT 602 PM CST MON DEC 15 2014

ALLOWED THE DENSE FOG ADVISORY ACROSS NORTH CENTRAL WISCONSIN TO
EXPIRE AT 6 PM CST. LIGHT RAIN ACROSS THE AREA HAS HELPED BREAK UP
THE FOG WITH VISIBILITIES GENERALLY IMPROVING TO MORE THAN ONE

.SHORT TERM...(THIS EVENING THROUGH TUESDAY)
ISSUED AT 246 PM CST MON DEC 15 2014

MAIN FORECAST CONCERNS ARE ON FOG THIS EVENING AND THE POTENTIAL FOR
A BRIEF WINTRY MIX LATE TONIGHT INTO TUESDAY MORNING.

DENSE FOG LOOKS TO LINGER OVER NORTH CENTRAL AND CENTRAL WISCONSIN
THIS EVENING BEFORE A COLD FRONT MOVES IN LATE. LOW PRESSURE WILL
TRACK ACROSS SOUTHERN IOWA/NORTHERN ILLINOIS TONIGHT PULLING THE
COLD FRONT ACROSS THE UPPER MISSISSIPPI RIVER VALLEY. LOOK FOR THE
LIGHT RAIN OVER THE AREA TO SWITCH OVER TO A SLEET/SNOW MIX
TONIGHT AS COLDER AIR MOVES IN. THERE MAY EVEN BE A VERY BRIEF
PERIOD OF LIGHT FREEZING RAIN. HOWEVER WITH THE RECENT WARM
TEMPERATURES AND THE COLDER AIR AT THE SURFACE ARRIVING
LATER...NOT EXPECTING SIGNIFICANT IMPACTS. WILL HAVE TO KEEP A
VERY CLOSE EYE ON TEMPERATURES TONIGHT. IT WILL BECOME WINDY
TONIGHT...ESPECIALLY OVER THE OPEN AREAS OF SOUTHEAST MINNESOTA
AND NORTHEAST IOWA. PLAN ON NORTHWEST WINDS INCREASING TO 18 TO 23
MPH WITH GUSTS APPROACHING 40 MPH AT TIMES. THE WINDS WILL
GRADUALLY SUBSIDE TUESDAY MORNING AS THE GRADIENT WEAKENS. PLAN ON
CLOUDY SKIES TOMORROW WITH HIGHS RANGING FROM THE MID 20S OVER
SOUTHEAST MINNESOTA TO THE MID 30S ACROSS FAR SOUTHWEST WISCONSIN.
THESE HIGHS WILL OCCUR EARLY IN THE THE DAY...THEN TEMPERATURES
GRADUALLY FALL DURING THE LATE MORNING INTO THE AFTERNOON HOURS.

.LONG TERM...(TUESDAY NIGHT THROUGH MONDAY)
ISSUED AT 246 PM CST MON DEC 15 2014

AN UPPER TROUGH MOVES OUT OF SOUTHERN CANADA TUESDAY NIGHT
THROUGH WEDNESDAY BRINGING FLURRIES TO THE REGION.
OTHERWISE...PLAN ON LOWS FALLING INTO THE UPPER TEENS TO LOWER 20S
TUESDAY NIGHT WITH HIGHS MAINLY IN THE 20S ON WEDNESDAY. THE
STRATUS LOOKS LIKE ITS HERE TO STAY AT LEAST THROUGH EARLY
THURSDAY WITH LOW LEVEL MOISTURE LINGERING ACROSS THE REGION. HIGH
PRESSURE LOOKS TO REMAIN OVER THE REGION THE REST OF THE WORK WEEK
WITH QUIET WEATHER EXPECTED. PLAN ON HIGHS IN THE 20S ON
THURSDAY...WARMING SLIGHTLY INTO THE UPPER 20S TO AROUND 30 BY
FRIDAY WITH LOWS IN THE UPPER TEENS TO LOWER 20S. THE QUIET AND
DRY WEATHER LOOKS TO PERSIST THROUGH NEXT WEEKEND. PLAN ON HIGHS
IN THE 30S THROUGH THE WEEKEND WITH LOWS IN THE 20S.
