- LIGHT SNOW TODAY
A WELL DEFINED COLD FRONT WAS LOCATED FROM IWD SOUTHWEST TO NEAR
OMA EARLY THIS MORNING, HEADING IN OUR DIRECTION. AHEAD OF THE
FRONT, RADAR SHOWED LIGHT SNOW COVERING NORTHEAST WISCONSIN AND
NORTHERN LAKE MICHIGAN. AS THE FRONT GETS CLOSER, CAMS SHOW LIGHT
SNOW DEVELOPING FARTHER SOUTH ACROSS THE LAKE AND WILL THEN SPREAD
INLAND. QPF AMOUNTS ARE AROUND A TENTH OF AN INCH ALONG THE
LAKESHORE COUNTIES AND HALF THAT INLAND. THIS WILL RESULT IN 1-2
INCHES OF SNOW WEST OF US-131 AND AROUND A HALF INCH ELSEWHERE.
MODELS SHOW THE LIGHT SNOW MOVING OVER THE NORTHWEST CWA AROUND
12Z AND THEN SPREADING SOUTH THE REMAINDER OF THE MORNING AND
EARLY AFTERNOON. WHILE HEAVY SNOW ISN'T EXPECTED, TRAVEL
CONDITIONS MAY BECOME SLIPPERY, SO KEEP THAT IN MIND IF TRAVELING
TODAY.
- CONTINUED COLD INTO NEXT WEEK, PERIODIC LIGHT SNOW
COLD AIR WILL POUR OVER THE CWA LATE TODAY AND TONIGHT BEHIND THE
COLD FRONT.H8 TEMPERATURES WILL FALL FROM -4C TO -18C BY 12Z
THURSDAY, SETTING THE STAGE FOR A VERY COLD DAY WITH HIGHS IN THE
LOWER 20S. VERY DRY AIR IS COMING IN BEHIND THE FRONT AND SO SNOW
SHOWERS WILL BE KEPT AT A MINIMUM.
THE CORE OF THE COLD AIR LIFTS OUT FRIDAY AND TEMPERATURES ON
SATURDAY WILL CLIMB TO AROUND 30. HOWEVER, ANOTHER COLD FRONT
MOVES THROUGH SATURDAY AND HIGHS SUNDAY AND MONDAY WILL BE IN THE
20S; NORMAL HIGHS ARE AROUND 40.
EACH ONE OF THESE COLD FRONTS WILL BRING A CHANCE OF SNOW.
HOWEVER, MODELS ARE SHOWING A CLIPPER SYSTEM AND ACCOMPANYING
SHORT WAVE MOVING ACROSS THE CWA NEXT MONDAY NIGHT. THIS WOULD
LIKELY RESULT IN SOME ACCUMULATION, SO WE'LL KEEP AN EYE ON IT.
AVIATION /12Z TAFS THROUGH 12Z THURSDAY/
ISSUED AT 618 AM EST WED DEC 3 2025
QUITE A BIT OF IFR CEILINGS ACROSS THE REGION THIS MORNING AHEAD
OF A COLD FRONT. THAT FRONT WILL MOVE SOUTH TODAY. ONCE IT MOVES
THROUGH, CEILINGS WILL IMPROVE A LITTLE. EXPECT SOME LIGHT SNOW
AS THE FRONT MOVES ACROSS THE TERMINALS. CONDITIONS WILL RETURN TO
VFR AFTER MIDNIGHT.
