...HEAVY RAIN AND FLOODING POSSIBLE LATE TONIGHT INTO THURSDAY...

AS A WARM FRONT LIFTS NORTH AND UPPER LEVEL DISTURBANCE MOVES OVER
THE AREA LATE TONIGHT INTO THURSDAY...SCATTERED TO WIDESPREAD
THUNDERSTORMS ARE EXPECTED TO DEVELOP. GIVEN THE VERY MOIST AIR
MASS IN PLACE OVER THE REGION...ANY THUNDERSTORM WILL BE CAPABLE
OF PRODUCING TORRENTIAL DOWNPOURS AND SIGNIFICANT AMOUNTS OF RAIN
IN A SHORT PERIOD OF TIME. CONFIDENCE IS LOW ON DURATION OF AND
WHERE THE MOST WIDESPREAD THUNDERSTORM ACTIVITY WILL FOCUS.
HOWEVER...THE INGREDIENTS ARE IN PLACE FOR AT LEAST MINOR URBAN
AND SMALL STREAM FLOODING FOR PARTS OF THE AREA TONIGHT. CONCERN
EXISTS FOR LOCALIZED FLASH FLOODING OVER AREAS THAT EXPERIENCE
CONTINUED THUNDERSTORM ACTIVITY FOR A LONGER PERIOD OF TIME.

STAY TUNED TO LATER FORECASTS AND THE POSSIBLE ISSUANCE OF A FLASH
FLOOD WATCH AT WEATHER.GOV/CHICAGO.
