The agency posted this statement on its website on Monday:

Severe thunderstorms are expected to return early this afternoon and continue through the evening across southeast Wyoming and Nebraska Panhandle. Storms are expected to become severe near noon to 1 pm today and could continue into this evening. Large hail to golfball size, damaging winds, and heavy rainfall are the expected thunderstorm threats. The tornado threat is low but can’t be ruled out over the Nebraska Panhandle.
