A cool day is forecast across KELOLAND with temperatures well below normal. Highs will be in the upper 50s to lower 60s this afternoon…levels that will rival record low highs for the date. Shower chances will continue at 30% to 40% today East River, with lower chances in the west. Rapid City should be a little warmer near 70 late this afternoon.
Look for overnight lows in the 40s for both Sioux Falls and Aberdeen with clearing skies. The numbers will rebound tomorrow into the lower 70s in many spots with lighter winds.
Expect warmer weather by the end of the week along with scattered thunderstorms again by the 4th of July. We may see more scattered t-storms on Saturday too in eastern KELOLAND. Temperatures will be on the increase with highs in the 80s in most areas by Saturday. A few 90s are possible West River.
While the extended forecast is warmer, the jet stream still looks strong along the U.S.-Canadian border. The heat ridge developing in the desert southwest won’t build as fast if this scenario plays out.
