— Flooding is <\/em>NOT <\/i><\/strong>expected today<\/em><\/p>\n

High temperatures will continue to slightly rise for another day with the ridge overhead. Expect a large change in the pattern starting tomorrow as the next system continues to move inland over the west coast and displaces the ridge eastward. PW<\/span> remains down this morning and was measured at 0.26 inches and 0.36 inches in Denver and Grand Junction, respectively. The moisture looks to be mostly located in the mid-level of the atmosphere and can be seen in water vapor imagery below (blue shades). This is expected to help generate a few afternoon showers over the southern and central high terrains and near the eastern Raton Ridge this afternoon, but a very dry surface layer means that the main threat will be gusty outflow<\/span> winds and lightning instead of wetting rainfall.<\/p>\n

\"\"<\/p>\n

Weaker mid-level moisture and lift will move across the northern border this afternoon as well, which is expected to spark some weak storms over the Front Range and Northern Mountains. Again, these will be high-based storms so plenty of virga<\/span> will limit the flood threat over the mountains and adjacent plains. Best chance for wetting rainfall will be isolated<\/span> storms that can make it into the far Northeast Plains. Flooding is not anticipated, but a quick 0.75 inches may be possible. As anticipated, no flood threat will be issued today.<\/p>\n

Today’s Flood Threat Map<\/strong><\/h3>\n

For more information on today’s flood threat, see the map below. If there is a threat, hover over the threat areas for more details, and click on burn areas to learn more about them. For Zone-Specific forecasts, scroll below the threat map.
\"\"<\/p>\n

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

Southeast Plains, Central Mountains, Southeast Mountains, Raton Ridge, Grand Valley, San Juan Mountains, Southwest Slope & San Luis Valley:<\/strong><\/h4>\n

Scattered<\/span> storms are possible this afternoon with some mid-level moisture and lift moving through the flow. The lower elevations of the Southwest Slope, San Luis Valley and Grand Valley look to remain dry with Red Flag<\/span> Warnings issued over these areas. Over the mountains, the best chance for accumulation will be near and along the Continental Divide<\/span> where isolated<\/span> rain rates up to 0.25 inches will be possible. Over eastern Raton Ridge\/Southeast Plains, max 1-hour rain rates up to 0.60 inches will be possible due to southerly\/south easterly surface winds pulling in some higher moisture. Flooding is NOT forecast today with the high cloud bases, but dangerous lightning, brief, strong outflow<\/span> winds and hail (east) will be possible under the strong thunderstorms that develop.<\/p>\n

Primetime: 1PM to 10PM<\/p>\n

Northwest Slope, Northern Mountains, Northeast Plains, Front Range, Urban Corridor & Palmer Ridge:<\/strong><\/h4>\n

Storms that pop over these region’s high terrains are forecast to be more scattered<\/span> early this afternoon. Plenty of virga<\/span> is forecast, but isolated<\/span> 1-hour totals around 0.20 inches are possible. As storms move off the higher elevations, they may produce some brief outflow<\/span> wind and rain rates should be reduced. If a storm or two can stay intact and make it into the far Northeast Plains, max 1-hour rain rates up to 0.75 inches will be possible along with brief, outflow<\/span> wind and hail. Flooding is NOT forecast this afternoon or evening.<\/p>\n
