Sioux Falls, SD
It’s a beautiful morning across KELOLAND and most areas will see sunshine today with highs in the upper 70s to lower80s in the east, with mid 80s central and west. Winds will be light to start, with south winds increasing to 10-20mph in Pierre and Rapid City. Thunderstorms will become possible tonight in western and central KELOLAND as instability returns. These storms will be very scattered, but could be strong where they develop.
A better chance of storms will develop tomorrow afternoon in central and northern KELOLAND as an upper level disturbance moves through the region and interacts with south winds and increasing instability. We’ll have to watch for supercell t-storms, those capable of large hail and isolated tornadoes. Those storms will eventually consolidate into 1 or 2 lines of storms through the evening as they move east.
Some additional development of thunderstorms will be possible in the east on Friday behind the main cold front. Temperatures will be trending cooler as we start the weekend with a good dose of 70s again across the east on Saturday.
Just as most students go back to school next week, the weather will be getting hotter with highs returning to the upper 80s to lower 90s by Tuesday!
