FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
408 AM CDT WED MAR 25 2026
DISCUSSION
STRONGER SOUTHERLY WINDS AND MORE SUNSHINE THIS AFTERNOON SHOULD
HELP PUSH HIGH TEMPERATURES INTO THE UPPER 60S TO MID 70S THIS
AFTERNOON. ASSUMING WE SEE A FAIR AMOUNT OF SUNSHINE THIS
AFTERNOON, THEN MINIMUM RELATIVE HUMIDITY VALUES WILL LIKELY
BOTTOM OUT IN THE 20 TO 30 PERCENT RANGE. WINDS WILL INCREASE TO
15 TO 25 MPH THIS MORNING AND CONTINUE INTO THE AFTERNOON WITH A
FEW GUSTS OVER 30 MPH POSSIBLE.
THURSDAY WILL BE UNSEASONABLY WARM WITH HIGHS WELL INTO THE 70S
ACROSS MOST OF THE AREA AND EVEN INTO THE LOW TO MID 80S SOUTH OF
I-80. A POWERFUL COLD FRONT WILL DROP THROUGH THE AREA FROM NORTH
TO SOUTH THURSDAY AFTERNOON AND EVENING, RESULTING IN A DRAMATIC
DROP IN TEMPERATURES -- PARTICULARLY CLOSER TO LAKE MICHIGAN,
WHERE TEMPERATURES COULD DROP WELL OVER 20 DEGREES IN A SHORT
PERIOD OF TIME. GUSTY SOUTHWEST WINDS ARE EXPECTED AHEAD THE
FRONT, SHIFTING TO GUSTY NORTHERLY WINDS BEHIND THE FRONT.
SHOWERS AND THUNDERSTORMS WILL DEVELOP IN ASSOCIATION WITH THIS
FRONT THURSDAY AFTERNOON, LIKELY CONTINUING INTO THE EVENING
HOURS SOUTH OF I-80 WHERE THE HIGHEST RAINFALL TOTALS ARE
EXPECTED. RAIN WILL END AREAWIDE THURSDAY NIGHT WITH DRY
CONDITIONS EXPECTED THEREAFTER AND THROUGH THE WEEKEND. SEASONABLY
COOL TEMPERATURES FRIDAY WILL GRADUALLY MODERATE OVER THE UPCOMING
WEEKEND.
