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

The gray hue in the visible satellite image below is actually smoke from all the wildfires that are currently burning over the western US. In total, there are about 75 large wildfires with 5 of those large fires burning in Colorado. Marked in red is a departing trough<\/span>, which is causing the cloudiness over SE Colorado and rain over Kansas. Today, the High will start to strengthen and northerly flow will pull in a drier air mass into the state. With weak upslope flow anticipated this afternoon in a drying environment, little to no rainfall is expected over the mountains. Best chance for measurable rain will be if the cap<\/span> over the eastern plains can break. Without a lot of upper support to help with lift, not thinking this this is too likely. However, if does occur, the weak thunderstorms should be fairly isolated<\/span>. Flooding is not expected today.<\/p>\n

Hot temperatures are also forecast with mid to upper 90Fs along the I-25 Corridor, upper 80Fs for the mountain valleys, and 100F over the Grand Valley\/lower elevations of western CO. Calmer surface winds means there’s no Red Flag<\/span> Warning<\/span> issued today, but if some mid and upper level moisture can spark a weak storm over the mountains, brief windy conditions may be possible.<\/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

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

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

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

High temperatures will be on the rise today, but an increase in cloudiness back to the west will help provide some respite from the heat this afternoon. Looking a little too dry today for afternoon storms over the mountains, but a few sprinkles are still possible along and near the Continental Divide<\/span> and southern Southeast Mountains. Storms may produce some brief windy conditions, but large damaging gusts are not currently forecast.<\/p>\n

There’s also a slight chance for some weak thunderstorms to pop over the eastern plains (along a convergence boundary), but equal chance that there isn’t quite enough lift to get these going. If storm do break the cap<\/span>, they should be fairly isolated<\/span> and produce more wind than rain. Max 1-hour rain rates up to 0.45 inches will be possible, so flooding is not forecast.<\/p>\n

Primetime: 1:30PM to 8PM<\/p>\n

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

Chances for afternoon and evening rainfall decreases today, but that also means less chance for windy conditions with the dry boundary layer<\/span>. A few high-based storms could still initiate over the southern San Juan Mountains, but only trace<\/span> amounts of rainfall are forecast. Highs will likely hit the 100F tick over the lower elevations of the Grand Valley and Southwest Slope again, so above average heat remains in the forecast. Not much change in the near surface smoke conditions, and an increase in smoke expected over the Northwest Slope.<\/p>","protected":false},"excerpt":{"rendered":"
