FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
359 PM CDT WED MAR 25 2026
DISCUSSION
AN ELEVATED FIRE DANGER WILL CONTINUE THROUGH THE REMAINDER OF
THIS AFTERNOON WITH RH VALUES BETWEEN 15 AND 30% (LOWEST NEAR AND
EAST OF I-55) AND BREEZY SOUTH-SOUTHWESTERLY WINDS GUSTING TO
AROUND 30 MPH. RH VALUES WILL RISE AND THE WINDS WILL DIMINISH
CLOSER TO SUNSET.
THURSDAY WILL BE UNSEASONABLY WARM FOR A LARGE PORTION OF THE
AREA. AFTERNOON HIGH TEMPERATURES IN THE 80S WITH MINIMUM RH
VALUES BETWEEN 40 AND 50%, MIXING HEIGHTS OF AROUND 4000 FT AGL
OR HIGHER, AND BREEZY SOUTHWESTERLY WINDS ARE EXPECTED IN MOST
AREAS SOUTH OF I-80. FARTHER NORTH, THERE IS GREATER FORECAST
UNCERTAINTY OWING TO LOW CONFIDENCE WITH THE ARRIVAL TIME OF A
STRONG COLD FRONT. SHARPLY COLDER TEMPERATURES AND BLUSTERY
NORTHERLY TO NORTHEASTERLY WINDS ARE EXPECTED NORTH OF THE FRONT,
WITH AN ABRUPT WIND SHIFT AND THE POSSIBILITY FOR TEMPERATURES TO
DROP OVER 20 DEGREES IN A SHORT PERIOD OF TIME BEHIND THE FRONT'S
PASSAGE. IT IS QUITE POSSIBLE THAT OUR TEMPERATURE, RH, AND MIXING
HEIGHT FORECAST IS TOO OPTIMISTIC FOR MANY AREAS NEAR AND NORTH
OF I-80 WITH RECENT MODEL GUIDANCE TRENDING TOWARDS A FARTHER
SOUTH POSITIONING OF THE FRONT BY MIDDAY AND A QUICKER FRONTAL
PASSAGE OVERALL.
SHOWERS AND THUNDERSTORMS WILL DEVELOP ALONG AND BEHIND THIS
FRONT THURSDAY AFTERNOON AND CONTINUE INTO THE EVENING HOURS NEAR
AND SOUTH OF I-80, WHERE THE HIGHEST RAINFALL TOTALS ARE
EXPECTED. RAIN WILL END AREAWIDE THURSDAY NIGHT WITH DRIER
CONDITIONS EXPECTED THEREAFTER AND THROUGH THE WEEKEND. SEASONABLY
COOL TEMPERATURES FRIDAY WILL GRADUALLY MODERATE OVER THE
UPCOMING WEEKEND.
