Scattered showers and storms have developed in western and central South Dakota. The showers and storms are moving east and some contain brief heavy rain and small hail. Most of the rain will go away as the sun sets, leaving much of the overnight dry. Overnight lows will fall to the fifties.
Tuesday will be sunny and warmer. Highs will make the eighties in central and western KELOLAND to near eighty in eastern South Dakota. Southerly winds will remain light at five to fifteen miles per hour.
Wednesday will most likely be the warmest day this week with temperatures in the low to middle eighties. Isolated nineties cannot be ruled out in south central and western South Dakota. Southerly winds will be a little stronger on Wednesday to help bring in the warmer air and a slight increase in humidity. As a cold front swings through KELOLAND on Wednesday night, scattered showers and storms will interact with the increased humidity. Some of the rain will last into Thursday for eastern KELOLAND while the central and west dry out. Temperatures on Thursday will range from the sixties in western KELOLAND to the middle seventies in the southeast. Northerly winds will help make it feel a tad cooler.
As high pressure settles in over KELOLAND Thursday, expect temps to fall to the forties for many locations by Friday morning. The taste of autumn will last into the first half of the weekend with temperatures slowly rebounding on Sunday and into early next week.
