Localized tornado outbreak possible in southeast SD today!
Intense thunderstorms capable of strong tornadoes appear likely this afternoon and evening across eastern South Dakota and northeast Nebraska. A mid-level shortwave trough is ejecting out of southern Montana right now; later this afternoon, a strong surface low is expected to develop over south-central South Dakota, bringing plenty of wind energy into northeast Nebraska and southern SD. Extreme instability is anticipated over this same area, and the latest
RUC models suggest that storms should initiate by about 21z. This environment looks very favorable for tornadic activity, so residents should definitely be mindful of changing conditions. A number of our northern Plains live-streamers will be covering this event as well, so you can follow them on the
Live page, as always! Strong storms are also possible over parts of the east coast, including the Delaware River areas in northeast PA east into the New York City vicinity -- lots of storms expected today across the US!
Also, yesterday was a pretty eventful severe weather day for the Great Lakes region. Storm chaser Andrew Pritchard caught the tornado below near Fort Atkinson, WI, one of several tornadoes this storm produced!
