Everyone everywhere says “if you don’t like the weather here, wait for 15 minutes” or something like that. Denver, though, is perhaps the most variable city in the country and we get to forecast for it! Joy.

At 1005AM, MT, Denver was reporting clear skies and a temperature of 59 degrees. These conditions belied an increasingly active p, Low attern in the northern Rockies, as a deepening trough is going to bring some precipitation to the higher terrains this afternoon and evening. It is a shallow amplitude feature and will sweep through the region quickly. There may be a splash of precipitation on Saturday morning.
The jet stream at this moment is shaped like a w, and the second lobe will strafe the northern Rockies on Sunday. As the trough emerges in the northern Plains, surface low pressure will develop, with a cold front tailed into the Denver region. This is he most likely time for the area to see wet weather this weekend, with a few afternoon thunderstorms, particularly east of town, a strong possibility.
