100+ mph winds possible for parts of the Dakotas and Minnesota tomorrow associated with a developing convective cluster and could-be derecho. A shortwave trough riding the ridge, responsible for the heat across the plains, should induce thunderstorm development fairly early in…

NWS is hiring! The first of several top-priority, mission-critical positions posted Friday on USAJobs.gov! Others will follow soon. Visit and search “NWS” to learn more.
Modeled soundings this evening are starting to exhibit classic derecho features. Notably, very deep low-level moisture yielding pwat values near 2.0" below an EML providing instability for leading thunderstorms but also mid-level dry air for rear inflow jet thermodynamics.
Derecho possible today

Let's talk about the forecast for the next few days. We're going to briefly be in a pattern called the "Ring of Fire," whereby clusters of storms parade around a dome of heat. You probably already noticed that heat is already building in our region (it's quite humid outside!)
July in the Northern Plains >>> March grunge in the Southeast

Very intense tornado has damaged structures W of Watertown SD
Incredible tornado to the west of Watertown @NWSAberdeen #sdwx
