The storm system will give eastern KELOLAND a chance for rain tomorrow, with rain amounts near a quarter inch possible in north central and northeast South Dakota, from near Gettysburg to Watertown and northeast. Rain amounts will be less in southeast KELOLAND. Highs tomorrow will be closer to average with a lot of forties on the temperatures map, but southeast KELOLAND might be able to squeeze into the fifties.
Everyone will have temperatures in the forties by Thursday and it looks like the cool air should last for the rest of the seven-day forecast and beyond. Along with the cooler air, we’re still watching a storm system to our south for Thursday night and Friday morning. At the moment, it looks like this storm system will give northwest Iowa a chance for rain or snow. If it takes a slight track to the north, then the chance for rain/snow will also move to the north into South Dakota and Minnesota.
A cold front will move into eastern KELOLAND tonight and Wednesday morning. This front will bring west/northwest winds and cooler temperatures to eastern KELOLAND. At the same time, snow will be possible tonight in the northern Black Hills with amounts of three to six inches possible for areas such as Lead, Deadwood, and Spearfish. Rapid City might have a couple of flakes of snow, but I don’t expect much (if any) accumulation in Rapid City.
