At 1053AM, MT, Cheyenne was reporting a temperature of 50 degrees with sunny skies and a brisk northwest wind of about 25mph in gusts. The off-mountain winds are certainly helping to bolster the warm up this afternoon. There was a weak ridge building in the front range as well, but most of the warm up at this time is mechanical in nature.
The upper level pattern is quite static, and a glance at the jet pattern looks to remain unchanged through the beginning of the work week. This means a tight thermal gradient just to the northeast of Cheyenne, which will result and a continuing brisk wind in the region. If the wind continues to be more westerly than northerly, Cheyenne will also be able to sustain some warmer temperatures.

A look at the satellite shows some striations in the clouds north of Cheyenne, which are caused by the strength of the jet through those clouds.
