A pleasant mid-week lull The upper-level ridge of high pressure near the Four Corners region is drifting a bit further to the west than models were showing a few days ago. As a result, this will keep most of Colorado in a west or west-northwest flow regime....significantly hampering the chance for showers and storms across the area both today and tomorrow thanks …

Zero percent Today is the only day this week that will offer a ZERO percent chance of rain around Boulder and Denver. Drier west-southwest flow has downsloped into the Front Range, effectively scouring out the low-level moisture that has been with us for the better part of a week now.

Another round of late-day storms The weather theme for the rest of the week will be decreasing atmospheric moisture content and rising temperatures across the Front Range, though the overall changes will be rather slow to materialize for us thanks to a stagnant large-scale pattern. For today, we're generally within a small-scale ridge, though some pieces of energy are embedded …
