Tornado Watch until 1 am (includes all of central MN)

Tornado Watch Until 1 am Wednesday. A watch means "watch out", stay alert, keep an eye on the sky, and stay tuned to local media, make sure your NOAA Weather Radio is turned on, and be ready to head to the basement (or an interior "safe room") if skies turn threatening. SPC has issued this watch until 1 am tomorrow. It includes the northern suburbs of the Twin Cities, St. Cloud and Alexandria, but people living near Brainerd and the Twin Cities should not be complacent. If you live close to a watch box, within 50-75 miles, you may be impacted too.
