— Flooding is NOT expected today
Quiet weather day in store as the ridge begins to build back to the north and produces subsidence (sinking motion) over the state. There is currently some cloud cover over the northwest corner, which is marked below. This should begin to break up as morning heating occurs and the low level moisture mixes out by noon. There is a much drier air mass in place over the state with PW measured at 0.57 inches and 0.55 inches in Denver and Grand Junction, respectively. Not expecting any rainfall today, but there will be some broken cloud cover over the higher terrains and western Colorado border this afternoon. Clouds look to increase overnight for the Southeast Mountains and eastern Plains, so it will be a cooler start to Monday morning. Flooding is not forecast.
