Issued at 155 PM CDT Fri Oct 16 2026

An area of high pressure over the region is producing cool temperatures across the forecast area with readings in the 40s and 50s. These readings are 5 to 10 degrees below average for this time of year. With the cool atmosphere, temperatures could fall quickly upon sunset, with reading in the 30s. Solely based the forecast low temperatures, have issued a frost advisory for the James River Valley, and a freeze warning further east. While marginal conditions, will lean on the side of caution for these headlines. As the surface high shifts southeast of the region, the forecast area will see increasing southerly winds, with gusts possible exceeding 35 to 45 mph along the higher terrain areas. There is a 40-70% chance for wind gusts to be greater than 45 mph along the eastern edge of the Sisseton Hills. The winds, along with some temperature advection may cause temperatures to become steady or slowly rise Saturday morning.

Warmer temperatures will move into the area for the weekend with highs reaching the upper 50s and 60s. The upper level flow pattern through next week favors above average temperatures and mostly dry conditions. A deepening trough along the west coast will cause upper level ridging over the Northern Plains through most of the next work week. The west coast trough should move across the desert southwest and eventually into the area by the end of the work week and through next weekend.
