Notice the specks of orange and yellow embedded in the ridge across Utah. This subtropical energy will be trekking eastward into Colorado this evening and overnight tonight, providing added lift to enhance storms. Expect daytime heating to once …

The 500 mb pattern shows that the ridge of high pressure is now centered over eastern Utah. It will continue to push south and west over the next few days...away from Colorado! Similar to yesterday, we'll be under the influence of northwest flow aloft, with low-level easterly flow. With plenty of moisture and the ridge retreating westward, enough instability will …

Mostly sunny and warm with a few very isolated afternoon thunderstorms. High temperatures in the upper 80's.
