FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
334 AM CDT MON AUG 24 2026
DISCUSSION
HIGH PRESSURE WILL REMAIN OVER THE REGION THROUGH TUESDAY
RESULTING IN CONTINUED DRY CONDITIONS. TEMPERATURES TODAY WILL BE
ON THE SEASONABLY COOL SIDE WITH HIGHS ONLY IN THE MID TO UPPER
70S, BUT WITH DEW POINTS IN THE LOWER 50S AFTERNOON RH VALUES
SHOULD DIP TO AROUND 35-45%. WINDS WILL REMAIN OUT OF THE
NORTHWEST TODAY WITH SPEEDS AROUND 5-10 MPH, THOUGH A LAKE BREEZE
WILL TURN WINDS NORTHEASTERLY NEAR THE LAKE AND CREATE HIGHER
HUMIDITIES AND LOWER MIXING HEIGHTS IN ITS WAKE.
SIMILAR CONDITIONS ARE EXPECTED FOR TUESDAY, BUT WITH SLIGHTLY
WARMER TEMPERATURES IN THE LOWER 80S AS WINDS TURN MORE SOUTHERLY.
AFTERNOON RH VALUES ARE EXPECTED TO BE IN THE 40-50% RANGE TUESDAY
WITH PEAK MIXING HEIGHTS AROUND 5000-6000 FT.
OUR NEXT CHANCE FOR RAIN IS EXPECTED ALONG A COLD FRONT ON
WEDNESDAY, THOUGH COVERAGE OF SHOWERS AND STORMS CONTINUES TO BE
UNCERTAIN. A FEW STORMS COULD BE STRONG TO SEVERE HOWEVER.
