The Colorado Front Range Foothills communities will enjoy a positively balmy week with daytime temperatures topping out near 70 F and overnight lows only in the low to mid 40s F. The ridge of high pressure responsible for this fair weather will slowly shift eastward across the Central Rockies through mid week. As the axis of this high pressure area moves to our east on Wednesday, high cloudiness will be on the increase as Pacific moisture slowly seeps in from the west. Despite this cloudiness, temperatures will remain warm, and Thursday promises to be another dry day.
A deep storm system will slowly dig southward into the Great Basin starting on Friday and then remain nearly stationary somewhere along the Utah and Nevada border for the balance of the weekend. Ahead of this storm a cold front will push southward across northern and eastern Colorado Friday night resulting in increased chances of thunderstorms Friday evening. By Saturday moist upslope flow will result in steadier precipitation which will likely continue through Sunday before the storm slowly weakens and lifts out to our north and west.
At this time, it looks like it will be warm enough for mostly rain to fall in Nederland, Ward, Rollinsville, and Blackhawk. Precipitation totals will range from 1 to 2 inches in many areas in the Front Range mountains north of I-70, welcome moisture which could help stave off the fire season.
We’ll keep an eye on the temperatures with this storm and any possible snow. The upshot of all of this is that the Mothers Day weekend could be wet and cool. If you had outdoor plans, keep an eye on the forecast.
