/06Z TAFS THROUGH 06Z SUNDAY/... Issued at 1001 PM MDT Fri Sep 11 2026
A weak cold front has pushed through the area this evening, shifting surface winds from westerly to either northerly or northeasterly. There are low probabilities (<15%) of KCYS and the Nebraska terminals seeing low cloud development, primarily from 09Z to sunrise given the NE upslope flow. Confidence isn`t high enough given current obs/trends to include a PROB30 group for MVFR cigs. Winds will shift to more out of the SE tomorrow at 10-15 knots east of the Laramie Range. KLAR and KRWL will maintain westerly flow with gusts as high as 30 knots.
