— Flooding is NOT expected today
Subsidence and building high pressure should bring another day of mild weather to the state. Marked in the water vapor imagery below (blue) is the cold front that started to move through during the early morning hours. Not much moisture return behind the front, and with PW remaining under 0.50 inches and an increase in dry, northwesterly flow aloft, only cloud cover is forecast over the northern tier of the state. There should be plenty of sunshine elsewhere, so another beautiful day ahead. Surface winds are expected to turn easterly over the eastern portion of the state throughout the day, so slightly cooler temperatures on the magnitude of ~5 degF are forecast. High temperatures are forecast to be around the same as yesterday over western Colorado, so still above average. Without any rainfall anticipated, there is NO flood threat issued.
