FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
457 AM CDT FRI SEP 12 2025
DISCUSSION
AREAS OF FOG, SOME LOCALLY DENSE, WILL PERSIST THROUGH MID-MORNING
ACROSS PARTS OF THE AREA MAINLY NEAR THE IL-WI LINE. OTHERWISE,
EXPECT ANOTHER QUIET AND WARM AFTERNOON WITH HIGHS IN THE MID-80S.
THOUGH A LAKE BREEZE THIS AFTERNOON WILL RESULT IN COOLER
TEMPERATURES AND LOWER MIXING HEIGHTS NEAR THE LAKE.
A WARM FRONT WILL LIFT INTO THE AREA TONIGHT WHICH MAY ALLOW FOR
SOME SHOWERS AND THUNDERSTORMS TO DEVELOP LATE TONIGHT THROUGH
SATURDAY. IF STORMS DEVELOP, THEY WILL BE CAPABLE OF HEAVY
RAINFALL WHICH COULD RESULT IN LOCALIZED FLOODING. GREATEST STORM
COVERAGE IS CURRENTLY FORECAST EAST OF A ROCKFORD, IL TO
RENSSELAER, IN LINE.
DRY CONDITIONS RETURN SUNDAY AND ARE EXPECTED TO PREVAIL THROUGH
MUCH OF NEXT WEEK. TEMPERATURES EACH DAY ARE FORECAST TO BE IN THE
UPPER 80S TO NEAR 90, BUT DAILY LAKE BREEZES WILL KEEP
TEMPERATURES COOLER (70S AND LOWER 80S) NEAR THE LAKE. THE LAKE
BREEZES WILL ALSO RESULT IN LOWER MIXING HEIGHTS AND HIGHER RH
VALUES IN THEIR WAKE WHILE THE REST OF THE AREA HAS RH VALUES IN
THE 35-40% RANGE.
