FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
301 PM CST TUE FEB 17 2026
DISCUSSION
A FIRE WEATHER WATCH IS IN EFFECT FROM 9 AM TO 8 PM WEDNESDAY.
A PERIOD OF SCATTERED SHOWERS AND POSSIBLY AN ISOLATED
THUNDERSTORM (20% CHANCE) IS EXPECTED LATE THIS EVENING THROUGH
TONIGHT AS A DISTURBANCE PIVOTS THROUGH. RAIN AMOUNTS WITH ANY
SHOWERS/STORMS TONIGHT ARE NOT EXPECTED TO BE MUCH ONLY AROUND A
COUPLE TENTHS AT BEST. THOUGH WINDS TONIGHT WILL BE INCREASING
WITH SOUTHERLY GUSTS AROUND 25 TO 30 MPH.
HEADING INTO WEDNESDAY, A DRY-LINE WILL SWING THROUGH NORTHERN IL
AND NORTHWEST IN WHICH WILL BRING ANY SHOWERS TO AN END. BEHIND
THE DRY-LINE DEW POINTS WILL QUICKLY TANK INTO THE 20S (UPPER
TEENS IN SPOTS) WHICH IN COMBINATION WITH HIGHS ONCE AGAIN IN THE
MID 60S WILL CAUSE RH VALUES TO BOTTOM OUT AROUND 15-25% AREAWIDE.
IN COMBINATION WITH THESE DRY CONDITIONS, WINDS WILL ALSO REMAIN
GUSTY OUT OF THE WEST-SOUTHWEST WITH GUSTS AROUND 30-40 MPH WHICH
WILL MAKE CONDITIONS CLOSE TO RED FLAG CRITERIA. HOWEVER, WITH
FUEL MOISTURES POSSIBLY BEING A BIT MORE MARGINAL (ESPECIALLY IN
NORTHWEST IN) CONFIDENCE WAS NOT QUITE THERE TO ISSUE A RED FLAG
WARNING SO OPTED TO ISSUE A FIRE WEATHER WATCH FOUR OUR IL
COUNTIES NORTH OF I-80 FOR NOW.
WINDS WILL BEGIN TO SUBSIDE WEDNESDAY EVENING WITH DEW POINTS AND
RH VALUES EXPECTED TO IMPROVE WEDNESDAY EVENING 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.
