Scattered showers and thunderstorms have been developing during the morning across both northeastern KELOLAND and the far west. The main disturbance in Montana will be moving south today, providing the trigger for more scattered thunderstorms this afternoon. A few severe storms are possible, mainly in northeast SD extending into western MN. A few more strong storms are possible along the Nebraska/South Dakota border. The chance of rain is 50% East River and 40% West River with highs close to 80.
Any thunderstorm development today will exit KELOLAND this evening. Overnight lows should be mainly in the upper 50s to near 60.
Look for mostly sunny skies tomorrow with highs in the upper 70s to near 80. Highs will still be around 80 on Wednesday in Sioux Falls, with mid 80s central and west. Isolated t-storms are possible by the evening…mainly in the west.
Better chances of thunderstorms will develop Thursday afternoon West River…with development more probable East River Thursday night and Friday morning. This will be associated with a warm front, which will likely give us warmer weather on Friday. More scattered storms are possible this weekend as a stronger disturbance moves into KELOLAND from the northwest.
