Discussion
(This Afternoon Through Tuesday) Issued at 1035 AM MDT Wed Oct 28 2026
Mean upper troughing over the PAC NW and western Canada will support general SW flow through the remainder week with weak/dry impulses traversing the flow. Departing impulse giving way to clear skies today as winds shifts NW behind the sfc reflection. Expect highs in the 50s and 60s. Otherwise, for the rest of the week highs will generally be in the 60s, although things will cool down Friday some behind a weak cool front, with highs generally in the 50s that day. Mild this weekend as WAA and height rises spread NE ahead of the digging western CONUS upper trough. There is a low chance for a few showers Friday night toward central SD as a disturbance skirts the region and forces pos theta-e adv. Western CONUS upper trough will lift out the Pac NW early next week, with broad lift spreading into the region starting Sunday night. The best chance for precip will be Monday when the main trough passes over the region. Very warm system for early Nov, with mainly rain expected. However, enough cold air may entrain into the back of the system Monday to allow for some higher elevation snow across northeast WY and the Black Hills. This could some support some light snow accums chances there, esp in the northern Black Hills.
