We'll have mainly fair conditions through the overnight hours. Stronger winds from the south will push out of Nebraska and could lead to a few clouds in our south-central zones. There are minimal chances of rain amongst these clouds.
Into tomorrow, changes are starting to be more noticeable. Heat coming from our west that was seen in the Hills today will spread throughout much of our area and we'll have widespread highs in the 90s. Late in the day two systems come in. The first will bring stray chances of storms to the western Hills that could carry east. The latter comes from Nebraska and with instability we could pop just a couple of lighter rains but mainly southeast of Sioux Falls. Otherwise expect sunny daytime conditions.
Into Tuesday, morning showers could linger in the southeast but most should remain dry. A couple of our in-house computer models try to bring some unorganized rains in West River Tuesday but I've mainly left them out of your forecast.
Wednesday a cold front will finish moving through. We could get some rains from this, with a slightly better chance in the northeast than other areas.
Thursday through late Friday will be a few degrees cooler and more seasonal. We should see more sunshine in the west by then.
Saturday brings another chance of rains to our area.
