FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
427 AM CST TUE JAN 13 2026
DISCUSSION
BREEZY AND UNSEASONABLY MILD WEATHER CAN BE EXPECTED TODAY, WITH
TEMPERATURES REACHING THE UPPER 40S TO AROUND 50 DEGREES THIS
AFTERNOON. SOUTHWEST WINDS WILL SHIFT WESTERLY LATE THIS MORNING,
WITH GUSTS AROUND 30 MPH DEVELOPING AND PERSISTING THROUGH THIS
AFTERNOON. WINDS WILL SHIFT NORTHWEST TONIGHT BEHIND A COLD FRONT
AND WILL REMAIN BLUSTERY WITH GUSTS UP TO 35 MPH ON WEDNESDAY.
THESE BLUSTERY WINDS WEDNESDAY WILL BE ACCOMPANIED BY COLDER
WEATHER WITH TEMPERATURES IN THE UPPER 20S TO LOWER 30S AND WIND
CHILLS IN THE SINGLE DIGITS. SCATTERED SNOW SHOWERS AND FLURRIES
CAN ALSO BE EXPECTED OVER MUCH OF THE AREA LATE TONIGHT THROUGH
WEDNESDAY.
IN NORTHWEST INDIANA, THE ARRIVAL OF COLDER AIR AND STRONG
NORTHWEST WINDS DOWN LAKE MICHIGAN WILL HELP TO PRODUCE
ACCUMULATING LAKE EFFECT SNOW FROM WEDNESDAY INTO WEDNESDAY NIGHT
AND THURSDAY MORNING. HEAVIEST SNOW ACCUMULATIONS ARE EXPECTED TO
THE EAST OF PORTER COUNTY, THOUGH A COMBINATION OF SOME
ACCUMULATION AND BLUSTERY WINDS WILL LIKELY MAKE FOR HAZARDOUS
TRAVEL OVER AT LEAST PORTIONS OF PORTER COUNTY.
COLDER AND OCCASIONALLY BLUSTERY WEATHER IS EXPECTED TO PERSIST
THROUGH THE WEEKEND, WITH SEVERAL ADDITIONAL CHANCES FOR SNOW SNOW
SHOWERS AND SOME ACCUMULATION AREA WIDE.
