LAKE EFFECT CLOUDS WILL CONTINUE TO DRAPE ACROSS THE CWA
SOUTHEASTWARD FROM LAKE MICHIGAN. PERIODS OF FLURRIES WILL BE
POSSIBLE THROUGH THIS MORNING WITH THE CLOUD COVER. SOME
INSTABILITY FLURRIES TO LIGHT SNOW SHOWERS HAVE DEVELOPED NEAR
THE ARCOLA AREA IN ALLEN COUNTY DUE TO THE WARM DISCHARGE FROM
STEEL MILL ACTIVITY WITH THE COLD TEMPERATURES IN THE MIDDLE
TEENS AND HAVE DRIFTED SOUTHEASTWARD TOWARDS KFWA THIS MORNING.
LAKE EFFECT CLOUDS HAVE KEPT TEMPERATURES A FEW DEGREES WARMER
THAN WOULD HAVE BEEN WITH CLEAR SKIES WHICH AREAS WEST OF US-31
HAVE DROPPED INTO THE LOWER TEENS WITH LESS CLOUD COVER IN THOSE
AREAS. SHORTWAVE RIDGING IN PLACE HOWEVER, LAKE EFFECT CLOUDS
AND RECENT SNOWFALL SHOULD KEEP HIGH TEMPERATURES SLIGHTLY MUTED
WITH HIGHS TODAY RANGING IN THE MID TO UPPER 30S.
A CLIPPER SYSTEM WILL BEGIN PUSHING SOUTHEAST INTO THE GREAT
LAKES REGION WITH MAIN DISTURBANCE PUSHING THROUGH JUST NORTH OF
THE CWA. TIGHTENING IN THE PRESSURE GRADIENTS AHEAD OF THE
DISTURBANCE WILL BRING AN INCREASE IN THE SOUTHWESTERLY WINDS THIS
AFTERNOON WITH GUSTS UP TO 35 MPH POSSIBLE. THE FAST MOVING
DISTURBANCE WILL BRING A DUSTING FOR MOST PARTS OF THE AREA
ESPECIALLY THE NORTHEASTERN HALF OF THE CWA. LESS THAN 1 INCH OF
SNOWFALL EXPECTED.
WEDNESDAY WILL BRING A SHORT BREAK IN PRECIPITATION CHANCES WITH
HIGHS IN THE LOW 30S TO LOW 40S WITH THE WARMER TEMPS ACROSS THE
SOUTHEASTERN PORTIONS OF THE AREA. A STILL TRICKY FORECAST IS IN
PLACE FOR LATE WEDNESDAY INTO THURSDAY IN WHICH ANOTHER QUICK
MOVING DISTURBANCE BUT THIS TIME TRACKING WEST TO EAST ACROSS
SOUTHERN PORTIONS OF THE CWA. THIS WILL INCREASE CHANCES OF
LIGHT SNOWFALL FOR MAINLY LOCATIONS SOUTH OF US-24 WHERE AROUND
AN INCH OF ACCUMULATION WILL BE POSSIBLE. A FEW SPOTS COULD SEE
CLOSE TO THE TWO INCH MARK. HOWEVER, STILL WATCHING THIS
CAREFULLY AS GUIDANCE HAS NOT HAD A GOOD HANDLE ON THIS SYNOPTIC
SETUP AND IF THIS DISTURBANCE TRACKS A BIT FURTHER NORTH WOULD
BRING THE HIGHER AMOUNTS NORTHWARD WITH IT, OF COURSE THE
OPPOSITE IS TRUE WITH A MORE SOUTHERN TRACK WOULD MEAN LOWER
AMOUNTS. HIGHS ON THURSDAY WILL BE JUST A SMIDGE WARMER WITH
VALUES RANGING FROM THE MID 30S TO LOW 40S.
A STRONGER WEST TO SOUTHWESTERLY FLOW AT THE SURFACE WILL BRING
A DRIER AIRMASS WITH BREEZY TO GUSTY CONDITIONS ALONG WITH A
BOUT OF WARMING TO THE AREA FRIDAY AND SATURDAY WITH HIGHS EACH
DAY IN THE MID TO UPPER 40S AND LOW 50S, HOWEVER, SATURDAYS
HIGHS WILL OCCUR EARLY SATURDAY BEFORE A TROUGH AXIS WITH COLD
FRONT PUSHES SOUTHWARD INTO THE REGION AND BRINGS COLDER
TEMPERATURES AND INCREASED CHANCES FOR LIGHT SNOW SHOWERS
THROUGH SUNDAY MORNING. SUNDAY AND MONDAY OF NEXT WEEK WILL SEE
HIGH TEMPERATURES RETURN TO MORE NORMAL LEVELS WITH VALUES IN
THE 30S ACROSS THE AREA.

(30-40%) FOR A 2-4 HOUR PERIOD OF LIGHT SNOW. LIMITED MOISTURE
QUALITY AND NORTHWARD BYPASS OF MORE PRONOUNCED MID LEVEL
FORCING BRINGS INTO QUESTION WHETHER SNOW ACCOMPANIES THE FRONT
