A LOW FLOOD THREAT IS FORECAST TODAY FOR PORTIONS OF THE URBAN CORRIDOR, PALMER RIDGE, NORTHEAST PLAINS, FRONT RANGE, SOUTHEAST MOUNTAINS, SOUTHEAST PLAINS, AND RATON RIDGE.<\/em><\/p>\n

A shortwave<\/span> disturbance embedded in southwesterly flow aloft will invade Colorado today, triggering scattered<\/span> showers and thunderstorms across the state. The disturbance shows up distinctly in the water vapor image below, and is accompanied by plenty of mid-level moisture (blue\/white colors) to support the activity. For eastern Colorado, the low-level moisture will be sufficient to produce periods of moderate-to-heavy rainfall. Combined with a concern for small hail clogging drainage, and the potential for multiple thunderstorms impacting the same location, a low flood threat is warranted. A few thunderstorms will be on the strong-to-severe side, with the potential to produce large hail (up to 1.5” in diameter), strong winds, and an isolated<\/span> tornado.<\/p>\n

\"\"<\/a><\/p>\n

West of the Continental Divide<\/span>, low-level moisture will be a limiting factor on rainfall, keeping rain rates below flash flood<\/span> thresholds. The main impacts from storms will be gusty winds, light rainfall, and lightning, with plenty of virga<\/span> to be noted across the sky. For more information on rain rates and timing, please see the zone-specific forecast discussions below.<\/p>\n

Zone-Specific Forecasts<\/strong><\/h3>\n

Front Range, Urban Corridor, Palmer Ridge, Northeast Plains, Southeast Plains, Southeast Mountains, and Raton Ridge:<\/strong><\/h4>\n

Scattered<\/span> showers and thunderstorms are expected this afternoon and evening, with a few isolated<\/span> storms continuing until around midnight. Most will be garden-variety, producing periods of light-to-moderate rainfall, gusty winds, and lightning. The atmosphere will support a couple strong-to-severe storms today east of the Mountains, with the potential to produce periods of heavy rain, large hail (up to 1.5 inches in diameter), strong winds, and an isolated<\/span> tornado. Maximum rain rates are as follows:<\/p>\n

Front Range and Southeast Mountains: 0.5-1.0 inches\/hour
\nNortheast Plains, Urban Corridor, Palmer Ridge, and Raton Ridge: 1.0-1.2 inches\/hour
\nSoutheast Plains: 1.3-1.6 inches\/hour<\/p>\n

Timing: 1 PM – 10 PM, with a couple isolated<\/span> storms rumbling until Midnight-1 AM<\/p>\n

Northern Mountains, Northwest Slope, Central Mountains, Grand Valley, San Juan Mountains, San Luis Valley, and Southwest Slope:<\/strong><\/h4>\n

Scattered<\/span> showers\/thunderstorms are expected this afternoon and evening, with the best coverage over the higher terrain of west-to-east oriented ranges. “Inverted-V<\/span>” soundings characterized the environment today (low-level moisture is lacking), so the main impacts from storms today will be light rain, gusty winds, and lightning. Generally speaking, rainfall rates will be in the 0.1-0.2 inches\/hour range, with maximum rates around 0.2-0.3 inches\/hour.<\/p>\n

Timing: 11 AM – 8 PM for the Southwest Slope and San Juan Mountains, Noon – 10 PM for the other regions<\/p>","protected":false},"excerpt":{"rendered":"
