Clouds from last night’s storms south of Sioux City persisted into the morning today, with a few areas of light rain as people headed to work. Cloud cover persisted in and southeast of Sioux Falls, but cleared out by noon. Conditions have been humid for most of southeast KELOLAND and along the Missouri River with dew points in the 60s. Temperatures have been in the mid 70s and low 80s, with the warmest temperatures in central and northeast South Dakota.
Tonight light rain is possible throughout KELOLAND, especially in the west and northwest parts of the state. The chance of thunder is low, but thunder may still occur in isolated areas as weak energy moves over our area. Rainfall will be around a quarter inch or less in areas that get it. Today’s humidity will keep tonight’s lows in the 60s with a bit of cloud cover. Winds will be fairly light overnight.
Tomorrow looks to have a better chance for showers and scattered thunderstorms. Instability is expected to be quite high, especially in eastern KELOLAND, so hail or strong winds will be possible with some of the stronger storm cells. Temperatures and humidity are also expected to be their highest of the week with temps in the mid to upper 80s, with dew points well into the 60s. Cloud cover is expected to trail off into the afternoon and evening hours
Wednesday through Friday will be more pleasant, as a weak high pressure system brings drier and cooler air. Highs will still be in the 80s, but nighttime temperature could get back into the 50s for eastern KELOLAND. Skies will be much clearer for that entire time period. Another round of rain is expected Saturday afternoon through Sunday for most areas along with the passage of a cold front. Weak thunderstorms may be possible. The beginning of next week will have sunny conditions with temperatures back in the 70s, normal for this time of year.
