— Flooding is NOT expected today
The visible satellite image below shows a mostly clear start to the day with some clouds and fog across the northeast corner of the state. The disturbance and moisture that is causing this will continue weaken throughout the morning, and conditions should become sunny by lunchtime. Dry WSW flow continues to scour out the remaining moisture, and as a result, PW at Grand Junction and Platteville have plummeted to 0.38 inches and 0.41 inches, respectively. With High pressure continuing to build over Texas and Oklahoma today, rising heights across should cause an increase in afternoon high temperatures when compared to yesterday. Between the lack of moisture and increasing subsidence, the state is expected remain dry this afternoon and evening. Best chance for a little bit of rainfall will be over the San Juan Mountains overnight where increasing southwesterly flow may bring a little moisture and mid-level lift to the area. However, only very light rainfall is forecast, so flooding is NOT expected.
