(This Evening Through Tuesday) Issued at 1254 PM MDT Tue Oct 20 2026

Current upper level analysis shows broad ridging over the central and western US with deepening trof off the west coast. The CWA sits under upper level southwest flow and clear skies. Sfc stations report light southerly winds across much of western SD with temperatures in the 60s to low 70s.

Weak front will cross the CWA overnight with the only impacts being a slight drop in tomorrow's highs and a brief period of breezy northwest winds overnight. Upper ridge builds over the region Wednesday into Thursday with southerly return flow supporting warming temps over the area.

Southerly winds pick up early Friday morning as upper level trof approaches with attendant sfc low and trailing cold front crossing the Northern Plains. WAA ahead of the front Friday afternoon will support highs in the upper 70s to low 80s over the western SD plains. As the front crosses the area later Friday evening, winds will shift to the northwest but remain breezy through the night, especially over northwestern SD. Much cooler conditions expected over the weekend with low chances for light precip.
