— Flooding is NOT expected today

As shown in the visible satellite imagery, below, for the first time in quite a while, there was not a cloud to be found over Colorado this morning. This does not always have predictive value, but today it will. Precipitable Water (PW) values this morning were in the 0.4 – 0.8 inch range, with only limited moisture in the boundary layer. Under light westerly flow, further gradual drying is expected today. With mid-level temperatures warming due to weak subsidence, rainfall coverage and intensity will decrease further today. Expect some isolated to possibly scattered showers and a weak thunderstorm in the climatologically favored Palmer Ridge and San Juans. However, flooding is not expected today.
