— Flooding is NOT expected today
Lingering cloud cover and a little fog remains over the far eastern plains from the storms that fired last night. The surface Low from yesterday is currently located over the southeast corner of the state and is forecast to move eastward throughout the day. As it exits, a few light showers may be possible on its north side over the plains. The exiting Low combined with dry, westerly flow aloft means that remaining moisture over the eastern portion of the state is forecast to decrease throughout the day. With PW values measured at 0.35 and 0.31 at Denver and Grand Junction, respectively, measurable rainfall is not forecast today. A couple sprinkles may be possible over the southern Front Range/Palmer Ridge this evening, but with high-cloud bases, the more likely scenario is virga. Flooding is not forecast.
