— Flooding is NOT expected today
Outside of some fog and cloud cover over the eastern border counties, it’s a clear and cool start to the morning. North and northwest flow has pulled in a dry air mass across the state, which is helping to produce the clear skies seen in the visible satellite imagery below. As anticipated, PW over Grand Junction and Denver has dropped to under a half inch with the dry air overhead. With subsidence behind the departing trough and a very dry atmosphere, rainfall is not expected today. The sinking air will also help to increase high temperatures when compared to yesterday, so expect above average temperatures to return. Flooding is NOT expected today.
