FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
336 AM CDT SAT MAY 30 2026
DISCUSSION
OUR STRETCH OF QUIET, DRY WEATHER CONTINUES THIS WEEKEND. EXPECT
HIGHS THIS AFTERNOON RANGING FROM THE MIDDLE 70S TO LOWER 80S
INLAND WITH 60S AND 70S NEAR THE LAKESHORE. BREEZY EAST WINDS WILL
GUST TO 20 TO OCCASIONALLY NEAR 25 MPH. AFTERNOON DEWPOINTS MIXING
DOWN INTO THE 40S WILL YIELD MINIMUM RHS AS LOW AS AROUND 30%.
TOMORROW WILL ALSO SEE HIGHS IN THE MIDDLE 70S TO AROUND 80 WITH
GENERALLY LIGHT WINDS.
THERE IS A SLIGHT CHANCE FOR A COUPLE OF LIGHT SHOWERS WEST OF THE
CHICAGO METRO SUNDAY NIGHT INTO MONDAY, PARTICULARLY OUT NEAR THE
I-39 CORRIDOR. IF RAIN DOES MATERIALIZE, IT DOES NOT LOOK LIKE
IT'D HAVE A NOTABLE INFLUENCE ON FUEL MOISTURES.
DRY CONDITIONS ARE FAVORED TO PERSIST THROUGH AT LEAST THE MIDDLE
OF NEXT WEEK WITH CHANCES FOR RAIN RETURNING TOWARD THE END OF THE
WEEK.
