Storm Center Update - Wednesday AM

We've got a cold front moving through but the bigger story continues to be very hot & humid weather across much of East River.  A Heat Advisory continues for the eastern two thirds of the coverage area.

With the cold front's passage comes a Wind Advisory.  North winds will pick up easily over 20 mph in the Hills, also changing the direction of the smoke plumes at times.  Eventually this will mean a little bit better shower chances.  Through the daytime hours, very isolated showers will likely form in central South Dakota but with spotty coverage, we don't expect much accumulating rain. 

Tonight, there are slight shower chances behind the cold front.  For now, the chances lie in the central parts of KELOLAND, though some of the newest data wants to place a few raindrops closer to Sioux Falls. 

Tomorrow will be about 5-10 degrees cooler in many spots, Rapid City excepted.  We'll still top out near 90 in Pennington County.  Winds will be more moderate out of the east and northeast. 

Friday looks like the best overall rain chance for the coming week.  Healthiest chances lie in Aberdeen, Pierre and central South Dakota.  Every tool is suggesting differing amounts and timing and that should start to clear up by this evening. 

Highs fall to the middle 80s for the weekend and Sunday looks mostly sunny!
