Storm Center Update-Monday AM

Sioux Falls, SD

Scattered thunderstorms continue in eastern KELOLAND this morning, with a few pockets of heavy rain near the Missouri River Valley and also in the far northeastern corner of South Dakota near Sisseton. In fact, the Sisseton storm has produced 3-5” as of 5:30am with flood warnings in effect for northern Roberts County. Most of the activity on radar will diminish toward late morning with highs returning to the upper 70s to lower 80s in the east. West River areas will likely top 90 this afternoon.

Tonight will be mild again with lows in the mid 60s and a chance of scattered t-storms in the west and north. Sioux Falls should be dry and the same is in the forecast for the Turner County fair tonight.

Tomorrow will be more active at times as a cold front starts the morning in western South Dakota and heads east during the day. We expect scattered t-storms to fire along the front during the afternoon, with the best chances of rain in northeastern KELOLAND. Sioux Falls should have a 40% chance of rain late tomorrow afternoon and evening as well. The front will clear the area Tuesday evening, leaving behind drier and slightly cooler trends for Wednesday.

Our next chance of scattered t-storms will return late Friday into Saturday. Warmer weather is expected to return to much of KELOLAND as well late in the week.
