DISCUSSION

Issued at 1241 AM CST Tue Nov 10 2026

Early this morning, some areas in the James River Valley have conditions that could support some localized areas of patchy fog. If fog were to develop, it will stick around into the morning before dissipating by mid-morning. The fog will cause lower visibilities at times, though visibilities should stay above one mile. High surface pressure over SD will be moving out during the afternoon, and it will continue to help to move some warm air into SD. Temperatures today will be 10-15 degrees above normal, with highs in the 50s to low 60s.

A low surface pressure will be pushing through SD this evening into the overnight hours. This low pressure will bring in some precipitation along the northerly side of it, with a 15-25% chance for some isolated rain showers and some sprinkles over portions of north central and northeastern SD and west central MN this evening into the early overnight hours. Not much rainfall is expected from these rain showers. The ensembles forecast that there is only a 10-25% chance for greater than 0.01 inch of rain fall over portions of north central SD and far northeastern SD and west central MN.

Cold air will be moving in behind the surface low Wednesday through Friday as some high pressure moves over SD. Temperatures will cool during that time to be around normal to slightly below normal Thursday and Friday. High temperatures during that time will be in the low 30s to mid 40s. The high pressure and some drier air in the atmosphere will help precipitation to stay out. As the high pressure moves out late Friday into the weekend, warmer than normal temperatures start to move back in, with above normal temperatures Sunday and Monday.
