FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
230 PM CST WED FEB 18 2026
DISCUSSION
A SIGNIFICANT EARLY SEASON FIRE WEATHER THREAT CONTINUES ACROSS
NORTHERN ILLINOIS THIS AFTERNOON. A RED FLAG WARNING REMAINS IN
EFFECT UNTIL 8 PM THIS EVENING.
A STRONG LOW PRESSURE SYSTEM HAS STALLED IN THE UPPER MISSISSIPPI
RIVER VALLEY, AND IS LEADING TO STRONG SOUTHWESTERLY GRADIENT
WINDS ACROSS THE REGION. SUSTAINED SPEEDS RANGE FROM 15 TO LOCALLY
30 MPH, AND GUSTS RANGE FROM 30 TO LOCALLY 50 MPH. THE STRONG
WINDS CONTINUE TO MIX VERY DRY AIR TO THE GROUND, WITH RELATIVE
HUMIDITY VALUES RANGING FROM 10 TO 20 PERCENT ACROSS THE AREA.
SEVERAL BRUSH FIRES HAVE ALREADY BEEN REPORTED OR DETECTED VIA
SATELLITE IMAGERY ACROSS THE AREA THIS AFTERNOON. THE NEXT FEW
HOURS WILL POSE THE GREATEST THREAT FOR WILDFIRE SPREAD. TOWARD
AND ESPECIALLY AFTER SUNSET, CONDITIONS WILL IMPROVE AS WINDS
DECREASE AND RELATIVITY HUMIDITY VALUES IMPROVE.
THE NEXT OPPORTUNITY FOR RAINFALL WILL ARRIVE ON THURSDAY AS
ANOTHER LOW PRESSURE SYSTEM DRIVES SCATTERED SHOWERS AND STORMS
THROUGH THE REGION. WITH THAT SAID, THE SYSTEM IS NOT EXPECTED TO
BRING WIDESPREAD SOAKING RAINFALL. TEMPERATURES WILL COOL TOWARD
SEASONABLE VALUES THIS WEEKEND.
