FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
912 AM CST WED FEB 18 2026
DISCUSSION
A SIGNIFICANT EARLY SEASON FIRE WEATHER THREAT WILL MATERIALIZE
TODAY ESPECIALLY ACROSS NORTHERN ILLINOIS WITH ELEVATED TO
LOCALLY CRITICAL CONDITIONS. A RED FLAG WARNING IS NOW IN EFFECT
FOR MUCH OF NORTHERN ILLINOIS FROM MID MORNING THROUGH THE EVENING
HOURS.
AS A STRONG LOW PRESSURE SYSTEM STALLS IN THE UPPER MISSISSIPPI
RIVER VALLEY, STRONG SOUTHWESTERLY GRADIENT WINDS WILL DEVELOP
ACROSS THE LOWER GREAT LAKES. SUSTAINED WINDS WILL INCREASE TO 20
TO LOCALLY 30 MPH WITH GUSTS OF 40 TO LOCALLY 50 MPH FROM MID
MORNING THROUGH THE EVENING. THE STRONG WINDS WILL TRANSPORT VERY
DRY AIR INTO THE REGION AS TEMPERATURES WARM, CAUSING RELATIVE
HUMIDITY VALUES TO PLUMMET TO THE 15 TO 25 PERCENT RANGE. EVEN
AFTER 0.05 TO LOCALLY 0.15" OF RAIN FELL LAST NIGHT ACROSS PART OF
NORTHEASTERLY ILLINOIS, PARTNERS IN THE FIRE WEATHER COMMUNITY
INDICATE THAT FINE FUELS SUCH AS GRASS WILL BE PRONE TO BURNING
TODAY. AS A RESULT, CONDITIONS WILL BECOME VERY FAVORABLE FOR THE
SPREAD OF FIRES TODAY. THESE CONDITIONS ARE RELATIVELY RARE FOR
OUR AREA, ESPECIALLY IN FEBRUARY. WINDS WILL SUBSIDE AND RELATIVE
HUMIDITY VALUES WILL RECOVER QUICKLY AFTER SUNSET.
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.
