–A LOW flood threat has been issued for portions of the San Antonio and Conejos Rivers
With the low to south and east of Colorado, the state will sit between two systems today. This will allow a weak ridge to begin to build back over the state and high temperatures to increase a couple of ticks on the thermometer compared to yesterday. The water vapor imagery below shows drier air over and around the area, which is indicated by the shades of yellow. Expecting most of the current low level moisture to mix out throughout the day, which should limit the coverage of the afternoon storms. Storms will be mostly confined to the mountains this afternoon and evening with steering winds from the north. The main threats will be gusty winds, brief/moderate rainfall and lightning. There is some weak mid-level energy over western Utah, which may help spark a couple additional showers over the northwest corner of the state this afternoon and evening, but flooding is not forecast. A Low flood threat has been issued for the San Antonio and Conejos Rivers, which are currently under a Flood Warning through Monday morning for minor flooding.

The exception is over the Northwest Slope where some mid-level energy may spark some weak showers later this afternoon. With low dew points most storms will produce virga and brief gusty winds. Totals should remain under 0.05 inches.
