Today’s record high in Boulder is 88 and in Denver it’s 90. We will get close but most likely stay below records. Above average temperatures and dry weather are likely in the Denver-Boulder-Fort Collins area into early afternoon Sunday.
A large, wet, and slow-moving storm system will be moving from southern Nevada to southern Wyoming in the Saturday to Tuesday time frame. That track would keep the heaviest precipitation to the west and north of the Front Range corridor. But the second half of the weekend is likely to be wet in Utah and western Colorado. I wouldn’t be surprised to see some news stories by late Monday regarding local flooding in the mountains of Utah and/or Wyoming.
For the Front Range the is a small chance for showers or thunderstorms late Sunday and a little better chance on Monday & Monday night with cooler temperatures, but not cold. If the storm track shifts a bit to the south, Monday could be quite wet in the Denver-Boulder area, but that appears unlikely at this time. Snow levels should be high, mainly above treeline.
