— Flooding is NOT expected today
Saturday’s active dynamics have long departed Colorado, leaving in their wake drying northwesterly flow (see water vapor image, below). PW at Grand Junction was all the way down to 0.16 inches, with Platteville also dropping substantially to 0.25 inches from yesterday morning’s 0.76 inches! Higher moisture does exist along the New Mexico, with a sliver of southwesterly monsoonal flow hanging on. There, PW is perhaps up to 0.7 inches, though it will likely drop a bit this afternoon.
With the drying conditions, we expect a beautiful fall day today with much warmer temperatures (especially for eastern Colorado). Along the New Mexico border, isolated to perhaps widely scattered storms are expected later this afternoon. However, only brief moderate intensity rainfall is expected. Thus, flooding is NOT expected today.
