Tom Green County on Tornado Watch for Thursday Evening

Posted May 19, 2017

A Tornado Watch means conditions are favorable for tornadoes and severe thunderstorms in and close to the watch area.

The National Weather Service has issued a Tornado Watch for 64 of 99 counties in Iowa. the counties include Winnebago, Hancock, Worth, Wright, Cerro Gordo, Humboldt, Franklin, Pocahontas, and Kossuth counties.

For preparation, Nagle suggested placing vehicles in the garage, if available, taking any outdoor decorations inside, and to pay attention for updates through the media or weather services.

Storms stayed west of Omaha and Iowa Wednesday morning.

While severe storms hit northern sections of Illinois, Central Illinois drivers dealt with poor visibility due to dust blown by high winds.

More widespread showers and storms are expected late Friday night and into Sunday as a cold front moves into the region.

Any storms that do develop are expected to end by midnight.

If you are driving, make sure to be cautious, because storms will greatly impact visibility.

Again, I have to emphasize that at this point it looks like most of the action will remain just outside our viewing area to the north with only a small chance of an isolated strong/severe storm developing southward into our area during the afternoon or early evening. Heavy rain could cause flash flooding, especially in hilly terrain. Most of these, beginning tomorrow, will be non-severe in nature.
