In the meantime, the eastern half of the continental U.S. will transition to above normal temperatures ahead of a pair of cold fronts next week that will bring readings back to closer to normal as we approach Thanksgiving Day.

Overview
A spring storm swept east across Wyoming, Friday, April 26th resulting in various weather conditions. Showers and a few thunderstorms pushed east into western Wyoming during the predawn hours Friday. Heavy snow occurred above 9000 feet with this activity, and Togwotee Pass became slick and snowpacked early Friday morning. The showers and a few thunderstorms then gradually shifted to areas east of the Continental Divide Friday morning. Isolated to locally scattered thunderstorms continued Friday afternoon with most of the thunderstorm activity generally along and south of a Jackson to Casper line.
A weak thunderstorm pushing east off the Wyoming Range into the Upper Green River Basin spawned a weak tornado that impacted Marbleton, Wyoming around 1230 PM.
Strong winds (45+ mph) were observed across much of western and central Wyoming Friday afternoon and evening from a combination of winds associated with thunderstorms, a tight pressure gradient, and a strong cold front.
