— Flooding is NOT expected today

Another mostly dry day for Colorado as westerly flow advects a dry air mass in from the west. This dry air mass can witnessed by the lack of cloud cover over Utah and most of Colorado in the visible satellite imagery below. There are some morning clouds associated with a disturbance over the Northeast and Southeast Plains. These should burn off and move east throughout the morning. High temperatures increase 3-5°F today with some stronger southerly surface winds forecast over the eastern plains. Other than some fair weather cumulus over the Front Range and Urban Corridor, it should be a clear day with PW measured at 0.35 inches and 0.51 inches at Grand Junction and Denver, respectively. A couple weak showers and maybe a clap or two of thunder will be possible over the Southeast Plains (southeast corner) as a disturbance moves in from New Mexico overnight. Flooding is not forecast.

Today’s Flood Threat Map

For more information on today’s flood threat, see the map below. For Zone-Specific forecasts, scroll below the map.

Zone-Specific Forecasts:

Central Mountains, Northern Mountains, San Juan Mountains, Northwest Slope, Grand Valley, Southwest Slope, San Luis Valley:

Temperatures should be on the rise today, but will cool off overnight. Approaching that time of year where the diurnal cycle really starts to amplify (difference between high and low temperature). Maybe a few clouds are possible over the northern high terrains, but clear conditions are forecast across all other zones. Should be a beautiful day, so try to kick off that weekend a little early!

Front Range, Southeast Mountains, Raton Ridge, Palmer Ridge, Urban Corridor, Southeast Plains, Northeast Plains:

Other than some fair weather cumulus and some light, overnight rainfall over the Southeast Plains, it should be a clear afternoon and evening. Expect high temperatures to increase a couple degrees, and this trend will continue through this weekend. Storm totals up to 0.25 inches will be possible over the Southeast Plains tonight and wouldn’t be surprised if there was a clap of thunder or two. This rainfall is associated with a disturbance moving in from New Mexico. Flooding is not forecast.
