Expect this trend to continue into this evening as a weak impulse moves east of the area. Otherwise a cool surface high will build into the CWA overnight and remain through the day Friday boding for cooler conditions. A few snow showers still possible over the higher mtns Friday though models continue to trend drier. Milder Saturday but a shortwave will drop se over the northern plains Saturday and drive another push of cooler air into the area setting up a chilly night Saturday night. .LONG TERM...(Sunday through Thanksgiving Day) Issued at 230 PM MST Thu Nov 19 2020 Dry and mild Sunday and Monday as a short upper ridge passes across the CWA.
