FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
351 AM CST FRI DEC 19 2025
DISCUSSION
A FEW LIGHT SNOW SHOWERS AND FLURRIES WILL LINGER THROUGH DAYBREAK
BEFORE SHIFTING EAST OF THE AREA. THOUGH LITTLE TO NO
ACCUMULATION IS EXPECTED. OTHERWISE, EXPECT BLUSTERY WEST WINDS
GUSTING 30-35 MPH THIS MORNING TO BECOMING WESTERLY AND GUST
AROUND 20-25 MPH THIS AFTERNOON.
ANOTHER STORM SYSTEM WILL MOVE INTO THE GREAT LAKES LATE TONIGHT
INTO SATURDAY WHICH WILL RESULT IN ANOTHER PERIOD OF GUSTY SOUTH
WINDS TONIGHT INTO SATURDAY MORNING WITH GUSTS AROUND 25-30 MPH.
PRECIPITATION CHANCES WITH THIS SYSTEM LOOK LIMITED LOCALLY, BUT
THERE REMAINS A SMALL CHANCE (<15%) FOR A PERIOD OF SPRINKLES
AND/OR FLURRIES NEAR THE IL-WI LINE ON SATURDAY.
GENERALLY ABOVE AVERAGE TEMPERATURES CAN BE EXPECTED SATURDAY INTO
NEXT WEEK WITH HIGHS IN THE 40S TO NEAR 50 EACH DAY. CHANCES FOR
MEASURABLE PRECIPITATION ALSO LOOK LOW THROUGH THE EARLY PART OF
NEXT WEEK.
