CHEYENNE, Wyo. (KGWN) The National Weather Service is calling for the main snow event to occur in the evening hours on Oct. 26 and finish around 6 a.m. on Oct. 28. The NWS says snow accumulation of 6-12 inches is possible across much of the region. The heaviest bands of snowfall are expected to set up across southeastern Wyoming into the northern Nebraska Panhandle.
The key concerns the NWS highlights are a possible flash freeze, impact to travel, and the timing. The flash freeze concern is due to the possibility of temperatures dropping about 40 degrees between Oct. 26 and Oct. 27 with wind chill values near zero during the morning hours on Oct. 27. The impact to travel concern is because of the possibility of snow-packed and icy roads with reduced visibility in falling snow while expecting drifting snow due to northeast winds gusting to 25 mph at times.
