FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
940 AM CDT SUN MAR 22 2026
DISCUSSION
WINDS ARE SOLIDLY OUT OF THE NORTH-NORTHEAST NOW THAT A COLD FRONT
HAS PASSED OVER THE AREA. WINDS ARE EXPECTED TO GUST AROUND 30 MPH
(OR HIGHER NEAR LAKE MICHIGAN) THROUGH THIS EVENING WITH MINIMUM
RHS IN THE LOW 60S. TEMPERATURES HAVE ALREADY FALLEN INTO THE 40S
NORTH OF I-80 AND WILL CONTINUE TO FALL AREA-WIDE THROUGH THE
AFTERNOON. LOW CLOUDS WILL ALSO SPREAD SOUTHWARD THROUGH THE DAY,
WITH A SLIGHT CHANCE OF SPRINKLES OR LIGHT SHOWERS IN THE
AFTERNOON.
COOLER CONDITIONS ARE EXPECTED EARLY THIS WEEK AS HIGH PRESSURE
CROSSES THE REGION. LIGHT NE WINDS ON MONDAY WILL RESULT IN
CHILLY CONDITIONS AND LOW MIXING HEIGHTS NEAR THE LAKE MICHIGAN
SHORE, WITH MIXING HEIGHTS LIKELY EXCEEDING 3 TO 4KFT INLAND.
A WARMING TREND IS THEN EXPECTED MIDWEEK. CHANCES FOR APPRECIABLE
PRECIPITATION REMAIN LOW THROUGH THE FORECAST PERIOD, THOUGH A
STRONG COLD FRONT MOVING ACROSS THE REGION ON THURSDAY MAY BRING
A PERIOD OF SHOWERS AND POSSIBLY THUNDERSTORMS.
