SHORT TERM
 
 
(ISSUED 227 PM CST SUN DEC 4 2022)  
 
TONIGHT THROUGH MONDAY NIGHT:  
 
AFTER TOPPING OUT IN THE MID TO UPPER 30S, TEMPERATURES WILL  
QUICKLY FALL INTO THE MID TO UPPER 20S THIS EVENING. SKIES WILL  
INITIALLY BE CLEAR, BUT HIGH CLOUDS WILL START TO BUILD INTO THE  
AREA AFTER MIDNIGHT. TEMPERATURES WILL LIKELY REACH OVERNIGHT LOWS  
BY MIDNIGHT OR SO, AND THEN HOLD STEADY OR EVEN RISE A DEGREE OR  
TWO BY MORNING.  
 
TEMPERATURES WILL STILL BE FAIRLY MILD TOMORROW, BEFORE SLIGHTLY  
COOLER AIR BUILDS IN BEHIND A PASSING COLD FRONT. ONE OR MORE  
BANDS OF LIGHT SNOW ARE EXPECTED IN ASSOCIATION WITH THE FRONT  
DURING THE DAY, MOSTLY NORTH OF I-94. ACCUMULATION WILL BE VERY  
MINOR, AND LIKELY CONFINED TO ELEVATED AND GRASSY SURFACES GIVEN  
MARGINAL SURFACE TEMPERATURES IN THE MID 30S. TEMPERATURES ARE  
EXPECTED TO FALL INTO THE TEENS AND LOW 20S BEHIND THE FRONT  
MONDAY NIGHT.

LONG TERM
 
 
(ISSUED 227 PM CST SUN DEC 4 2022)  
 
TUESDAY THROUGH SUNDAY:  
 
A WEAK WAVE WILL PASS THROUGH THE AREA ON TUESDAY, POSSIBLY  
BRINGING ANOTHER ROUND OF LIGHT SNOW OR A RAIN/SNOW MIX TO THE  
REGION. FORCING WILL BE WEAK AND MOISTURE WILL BE LIMITED, SO  
CONFIDENCE IS NOT HIGH.  
 
WEDNESDAY IS LOOKING FAIRLY QUIET, BEFORE A MORE ROBUST SYSTEM  
POTENTIALLY APPROACHES THE MIDWEST LATE IN THE WEEK. LOTS OF  
UNCERTAINTY AT THIS POINT WITH TIMING, TRACK, AND STRENGTH OF THE  
SYSTEM, WITH ENSEMBLES SUGGESTING A VERY WIDE RANGE OF POTENTIAL  
SCENARIOS. IT'S STILL FAR TOO EARLY TO SPEAK TO ANY PARTICULARS,  
BUT THIS IS A TIME PERIOD WORTH KEEPING AN EYE ON OVER THE COMING  
DAYS.  
 
OTHERWISE, TEMPERATURES THROUGH THE EXTENDED ARE FAVORED TO  
GENERALLY BE AROUND AVERAGE, WITH HIGHS IN THE 30S AND LOWS IN THE  
20S.

VFR WILL PREVAIL TONIGHT, WITH HIGH CLOUDS BUILDING INTO THE AREA  
DURING THE OVERNIGHT HOURS. WINDS WILL BE FROM THE SOUTHWEST, WITH  
A FEW GUSTS TO AROUND 20 KNOTS AT TIMES.  
 
CEILINGS WILL GRADUALLY LOWER DURING THE DAY ON MONDAY, WITH  
POCKETS OF MVFR POSSIBLE BY AFTERNOON. ONE OR MORE BANDS OF LIGHT  
SNOW WILL ALSO BE POSSIBLE, THOUGH MAINLY NORTH OF THE TERMINALS  
(WITH THE EXCEPTION OF SHEBOYGAN). WINDS WILL REMAIN FROM THE  
SOUTHWEST UNTIL MONDAY EVENING, WHEN THEY SWITCH TO A  
NORTHWESTERLY DIRECTION.

(ISSUED 227 PM CST SUN DEC 4 2022)  
 
HIGH PRESSURE OVER THE OHIO RIVER VALLEY WILL SHIFT EASTWARD AND  
WEAKEN A BIT TODAY INTO TONIGHT, AHEAD OF AN AREA OF LOW PRESSURE MOVING  
ACROSS SOUTHERN ONTARIO. STRONG SOUTHWEST WINDS WILL DEVELOP THIS  
EVENING TONIGHT BETWEEN THE DEPARTING HIGH AND APPROACHING LOW,  
WITH GALE FORCE WINDS LIKELY IN THE NORTH THIS EVENING INTO  
TONIGHT. A GALE WARNING IS IN EFFECT FOR THE NORTHERN HALF OF THE  
OPEN WATERS, WITH A SMALL CRAFT ADVISORY IN EFFECT FOR THE  
NEARSHORE.  
 
WINDS WILL THEN BECOME LIGHTER MONDAY INTO MID-WEEK AS HIGH  
PRESSURE GRADUALLY BUILDS BACK IN TO THE REGION.  
 
TOWARD THE END OF THE WEEK, THERE ARE SOME INDICATIONS THAT A  
STRONGER STORM SYSTEM MAY AFFECT PORTIONS OF THE MIDWEST AND GREAT  
LAKES. DEPENDING ON THE EVENTUAL TRACK AND STRENGTH OF THE SYSTEM,  
STRONGER WINDS COULD BE A POSSIBILITY LATE IN THE WEEK.
