Rainfall will be less in Sioux Falls and southern KELOLAD – less than a tenth of an inch – and heavier in the north. Aberdeen and the northern tier of counties in South Dakota could get a half to ¾: of rain. There might even be a little lightning. Rapid City will be breezy and cooler, as northwest winds bring in temperatures in the 60s.
Sunday will be partly cloudy and breezy, with lingering morning showers in central and eastern South Dakota. Temperatures will drop back to the upper 60s with the brisk NW wind.

Wednesday looks like it will very west across KELOLAND. Forecast models are putting out significant rainfall amounts, one to two inches in western and central South Dakota. Sioux Falls and the east could get an inch with showers and thundershowers. Wednesday will also be windy and cool, a raw day, with highs in the low to mid 60s. It will be even cooler in western South Dakota, and the Black Hills and even Rapid City could get a mix of rain and snow during the coldest part of the day.
The front should move away on Thursday, taking the rain with it. But there will be strong northwest winds, and it will be chilly with upper 50s to low 60s.
Temperatures will recover a couple degrees Friday through the following weekend (October 16-17), near-normal in the mid to upper 60s.
