Storms Near Black Hills Charge Toward Large Hail, 80 MPH Winds in Western SD — SevereWX

A cluster of strong thunderstorms is firing up near Belle Fourche in western South Dakota, just north of the Black Hills, with a severe weather threat ramping up fast.

The Storm Prediction Center highlights potential for isolated large hail up to 2.5 inches and severe wind gusts of 65-80 mph, plus a low-end tornado risk up to 90 mph intensity. These storms are riding the edge of robust instability—MLCAPE 2000-3000 J/kg—and decent shear around 30 knots, keeping them organized as they push east.

Expect the action to intensify over the next couple of hours, possibly spilling west into far southeast Montana and far northeast Wyoming if new cells strengthen there. SPC pegs watch issuance at 80% probability within the hour.

This ties into broader Plains severe patterns, with prior tornado warnings already active in South Dakota today. Track radar closely if you're in western SD, especially Rapid City to Spearfish areas.

Stay prepared: Monitor local NWS alerts, secure outdoor items, and have a severe weather plan ready. Check SPC's site for updates.
