FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
339 PM CDT TUE MAR 24 2026
DISCUSSION
SOMEWHAT STRONGER SOUTHERLY WINDS AND MORE SUNSHINE SHOULD HELP
BOOST HIGH TEMPERATURES INTO THE UPPER 60S TO LOWER 70S WEDNESDAY
AFTERNOON. LIMITED MOISTURE RETURN AND SOME MIXING OUT OF DEW
POINTS IN THE AFTERNOON SHOULD ALLOW MINIMUM AFTERNOON RH VALUES
TO DROP TO BETWEEN 20 AND 30 PERCENT, POSSIBLY AS LOW AS 15 TO 20
PERCENT SOUTH OF THE KANKAKEE RIVER ACROSS EASTERN ILLINOIS AND
NORTHWEST INDIANA. WHILE WINDS WILL BE STRONGER, THEY ARE EXPECTED
TO REMAIN SAFELY BELOW RED FLAG WARNING CRITERIA.
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 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.
