428 AM CDT THU APR 23 2026
DISCUSSION
TODAY WILL SEE WARM TEMPERATURES, GUSTY SOUTH WINDS, AND
MARGINALLY DRY CONDITIONS. SOUTH WINDS WILL BUILD THROUGH THE
MORNING AND REGULARLY GUST TO 25 TO 30 MPH DURING THE AFTERNOON.
TEMPERATURES WILL WARM INTO THE LOWER TO MIDDLE 80S THIS

DURING THE AFTERNOON WHICH WOULD YIELD MIDDAY RHS DOWN BETWEEN 35
AND 45%, LOWEST SOUTH OF I-80. HOWEVER, DEWPOINTS MAY MIX DOWN
CLOSER TO 50 DEGREES, WHICH WOULD BRING RH VALUES DOWN TO AROUND
30%. THIS DRIER OUTCOME WOULD RESULT IN A MARGINALLY ELEVATED RISK
FOR FIRE SPREAD THIS AFTERNOON. LOOK FOR ANY CHANGES IN FORECAST
THINKING IN THE MID-MORNING UPDATE.
A LINE OF SHOWERS AND THUNDERSTORMS WILL MOVE ACROSS NORTHERN
ILLINOIS AND NORTHWEST INDIANA VERY LATE TONIGHT INTO EARLY
FRIDAY. ADDITIONAL SHOWERS AND THUNDERSTORMS MAY DEVELOP FOR LATE
FRIDAY MORNING AND AFTERNOON, WITH BEST CHANCES FOR RAIN AFTER
