FIRE WEATHER PLANNING FORECAST FOR IOWA/ILLINOIS
NATIONAL WEATHER SERVICE QUAD CITIES IA/IL
222 PM CDT THU SEP 17 2026
DISCUSSION
THE PATTERN WILL REMAIN ACTIVE WITH PERIODIC ROUNDS OF
SHOWERS AND THUNDERSTORMS INTO EARLY NEXT WEEK. THE NEXT ROUND
OF RAIN WILL BE LATE TONIGHT INTO FRIDAY, BUT THIS
LOOKS TO BE A LOWER COVERAGE EVENT WITH MAINLY SCATTERED SHOWERS
AND ISOLATED STORMS. MORE WIDESPREAD RAIN IS ANTICIPATED FOR
FRIDAY NIGHT INTO SATURDAY MORNING. GIVEN THE WET PATTERN, THERE
ARE NO SIGNIFICANT FIRE WEATHER CONCERNS INTO EARLY NEXT WEEK.
THE GRASSLAND FIRE DANGER INDEX -GFDI- DOES NOT ACCOUNT FOR
PRECIPITATION THAT OCCURS OR ANY SNOW ON THE GROUND. PLEASE
MAKE APPROPRIATE ADJUSTMENTS.
