Isolated severe thunderstorms may occur over parts of south-central South Dakota this evening. Frequent lightning, damaging wind gusts and 1” hail will be the main threats. Monitor the weather and have a plan of action if severe weather is imminent.
A Red Flag Warning is in effect for all of northeast Wyoming and parts of northwest South Dakota from Noon to 8 PM MDT Saturday, August 8. Gusty northwest winds, very low humidity, and ongoing drought will create critical fire weather conditions, and any fires that start could spread quickly.
Hot and hazy conditions continue through early next week. Highs today will range from the 90s to low 100s with chances for thunderstorms - some strong to severe - over south central South Dakota. Not as hot on Sunday with highs in the upper 80s to 90s. There’s a chance for isolated afternoon storms over the Black Hills Sunday. Highs on Monday will be in the 80s to 90s with chances for afternoon storms over much of western South Dakota.
