FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
352 AM CST WED FEB 18 2026
DISCUSSION
A SIGNIFICANT EARLY SEASON FIRE WEATHER THREAT EXISTS TODAY
ACROSS A GOOD CHUNK OF NORTHERN IL. THIS IS PARTICULARLY THE CASE
FOR AREAS ALONG AND WEST OF THE FOX VALLEY AND I-55, WHERE THE
FIRE WEATHER WATCH HAS BEEN UPGRADED TO A RED FLAG WARNING.
DEWPOINTS ARE EXPECTED TO TANK INTO THE 20S FROM WEST TO EAST
ACROSS NORTHERN IL LATE THIS MORNING AND AFTERNOON FOLLOWING THE
PASSAGE OF FRONTAL BOUNDARY/QUASI-DRY LINE. THIS WILL RESULT IN
AFTERNOON RH PERCENTAGE VALUES FALLING AS LOW AS 15-25% (LOWEST IN
THE RED FLAG WARNING AREA) AS TEMPERATURES WARM INTO THE MID TO
UPPER 60S. IT IS QUIET RARE TO HAVE RH VALUES FALL BELOW 20% IN
THIS PART OF THE COUNTRY AT ANY TIME OF YEAR, LET ALONE IN MID
FEBRUARY. UNFORTUNATELY, THESE VERY DRY CONDITIONS WILL BE
ACCOMPANIED BY STRONG GUSTY WESTERLY WINDS (GUSTS OF 35 TO 45 MPH)
DURING PEAK HEATING THIS AFTERNOON, MAKING FOR ELEVATED TO
CRITICAL FIRE WEATHER CONDITIONS. ACCORDINGLY, OUTDOOR BURNING IS
NOT RECOMMENDED, PARTICULARLY IN THE RED FLAG AREA.
WINDS WILL SUBSIDE QUICKLY AFTER SUNSET THIS EVENING WITH DEW
POINTS AND RH VALUES EXPECTED TO IMPROVE AS WELL. OUR NEXT CHANCE
FOR PRECIPITATION WILL ARRIVE ON THURSDAY WITH MORE SCATTERED
SHOWERS AND THUNDERSTORMS EXPECTED. A FEW OF WHICH COULD BE STRONG
TO SEVERE. OTHERWISE, EXPECT MORE SEASONABLE CONDITIONS TO RETURN
THIS WEEKEND WITH HIGHS IN THE 30S AND LOWS IN THE TEENS AND 20S.
