A COLD FRONT CONTINUES TO SLOWLY SLIDE EAST THIS AFTERNOON, WITH
PLENTY OF ITS CLOUD COVER LINGERING AT THIS TIME. SHARP CLEARING IS
NOTED ACROSS NORTHERN IL WHICH SHOULD SET THE STAGE FOR
CLEARING SKIES THIS EVENING THROUGH THE NIGHT. THIS LOSS OF
INSULATION WILL SENT TEMPERATURES INTO THE LOW-TO-MID 40S
TONIGHT. DESPITE THE CLEAR SKIES AND RECENT RAINFALL, A
NORTHEAST WIND NEAR 5 KNOTS MAY BE JUST ENOUGH TO PREVENT
WIDESPREAD FOG FROM DEVELOPING. YET PATCHY GROUND FOG IS
CERTAINLY PLAUSIBLE, AS IS COMMON FOR OCTOBER.
HIGH PRESSURE SHIFTS EAST THROUGH THE WEEKEND AND A LOW RACES
THROUGH INTERIOR ONTARIO AS SUNDAY PROGRESSES. A TRAILING (AND DRY)
COLD FRONT DROPS THROUGH SUNDAY AFTERNOON, RESULTING IN A LATE-DAY
COOLING TREND INTO THE 60S DOWNWIND OF LAKE MICHIGAN. ANY RAIN
SHOWERS APPEAR CONFINED TO CENTRAL MICHIGAN AND POINTS NORTH. IN THE
WAKE OF THIS FRONT, A REINFORCING DOSE OF COLD, CANADIAN HIGH
PRESSURE DESCENDS OVER THE MIDWEST. CENTERED OVERHEAD TUESDAY
MORNING, MORNING LOWS ARE ON TRACK TO BE IN THE MID-TO-UPPER 30S.
THIS EPISODE OF COLD AIR IS SHORTLIVED AS UPPER-LEVEL FLOW REMAINS
PROGRESSIVE AND RIDGING RESUMES LATE-WEEK PUSHING AFTERNOON HIGHS
INTO THE LOW-70S.
