"Much of the area will see two to three inches of rainfall with the potential for localized bands of higher amounts. The heaviest rain will exit the area by midnight." Flash flooding is possible along the faster responding small river and streams across the watch area. As a result, urban and poor drainage flooding is possible as well.

Exercise caution during the evening commute. A total rainfall of 2-3 inches is expected with some locations possibly seeing higher amounts.
