Storms fire back up again overnight and Saturday morning

Remaining Ad Time Ad - 00:00

ROCKFORD (WREX) – A few more chances for rain and storms linger tonight, leaving a risk for flash flooding in place.

A warm front lifted north this evening, bringing in an environment favorable for strong and heavy rainfall. The air behind the front is very warm (near 80 degrees) and much more humid (dewpoints in the 70’s, which is very muggy). Flash flooding remains a concern overnight due to the muggy air and all of the recent rainfall. The soil can’t handle too much more rain without flooding.

Scattered thunderstorms will continue to pop up through 1 am, then settle down from there. Repeated downpours could lead to 1″ or more of new rainfall, causing flooding. Avoid any flooded roads if you are out driving late, and move away from streams or rivers if they start to rapidly flood.

Showers and storms may not wrap up until close to sunrise Saturday. The threat for severe thunderstorms and flash flooding doesn’t settle down until the early morning hours of Saturday. Storms should be much weaker by then, so the risk for severe storms will be lower. Have a way to get severe weather alerts. A weather radio is an extraordinary asset, especially during overnight severe risks.

Overnight will also feature the greatest chance for flash flooding. A flash flood watch goes into effect this evening at 7 and will be in effect until 10 AM Saturday. Rainfall rates could be on the order of one to two inches per hour. This could result in runoff not being able to properly absorb into the already saturated ground.

Much of the rest of Saturday looks dry, then scattered showers and storms may return in the evening. Same goes for Sunday; much of the day looks dry with storms staying to our south, but we still have a lingering chance for some storms. Memorial Day looks to have lighter rainfall, mostly during the morning and early afternoon.
