NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
309 PM CDT TUE MAR 10 2026
DISCUSSION
THERE IS A THREAT FOR STRONG TO SEVERE STORMS TONIGHT THAT MAY
PRODUCE LOCALLY HEAVY RAINFALL AND POSSIBLY FLOODING. LARGE HAIL
WILL BE THE MAIN SEVERE THREAT NORTH OF THE FRONT (TO THE NORTH OF
INTERSTATE 80), AND ALL SEVERE HAZARDS (INCLUDING TORNADOES) WILL
BE POSSIBLE TO THE SOUTH OF INTERSTATE 80. PRECIPITATION WILL END
FROM NORTHWEST TO SOUTHEAST ON WEDNESDAY, WITH A CHANCE FOR RAIN
TO MIX WITH OR CHANGE OVER TO SNOW NORTH OF INTERSTATE 80 JUST
BEFORE THE PRECIPITATION ENDS. NORTHWESTERLY WINDS MAY GUST AS
HIGH AS 35-40 MPH ON WEDNESDAY AFTERNOON.
DRY AND BREEZY CONDITIONS ARE EXPECTED ON THURSDAY. THERE IS SOME
POTENTIAL FOR DEWPOINTS AND RH VALUES TO FALL A BIT MORE THAN
CURRENTLY FORECAST.
ANOTHER STRONG STORM SYSTEM WILL MOVE NORTH OF THE REGION
THURSDAY NIGHT INTO FRIDAY. A PERIOD OF STRONG (POSSIBLY VERY
STRONG) SOUTHWEST TO WESTERLY WINDS WILL DEVELOP, AND GUSTS COULD
EXCEED 45 MPH BEFORE EASING LATE IN THE DAY ON FRIDAY.
AN ACTIVE PATTERN WILL CONTINUE THIS WEEKEND INTO EARLY NEXT WEEK
WITH CHANCES FOR RAIN AND SNOW AND THE POTENTIAL FOR A PATTERN
SHIFT TO COLDER TEMPERATURES EARLY NEXT WEEK.
