NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
229 AM CDT MON JUL 20 2026
DISCUSSION
TODAY WILL FEATURE BREEZY SOUTHWEST WINDS AND TEMPERATURES IN THE
MID TO UPPER 80S. CANADIAN WILDFIRE SMOKE MAY LINGER THROUGH THE
REGION, BUT SHOULD NOT BE AS BAD AS LAST WEEK.
A SEASONABLY STRONG STORM SYSTEM WILL MOVE THROUGH THE REGION
TONIGHT LEADING TO SCATTERED SHOWERS AND STORMS. WITH THAT SAID,
SOME AREAS MAY NOT SEE MUCH RAIN TONIGHT. A PAIR OF COLD FRONTS
WILL THEN MOVE THROUGH THE REGION ON TUESDAY, SETTING THE STAGE
FOR SEASONABLY COOL WEATHER WEDNESDAY THROUGH THE REMAINDER OF THE
WEEK.
TEMPERATURES MAY WARM ABOVE AVERAGE BY NEXT WEEKEND WITH A RETURN
OF CHANCE FOR SHOWERS AND STORMS BY EARLY NEXT WEEK.
