DENVER- Skies will stay mostly clear overnight with warm temperatures hanging on through the evening, thanks to a strong upper ridge in place. That ridge is pumping heat onto the eastern plains which we will definitely feel tomorrow. Overnight lows will be in the mid 60s tonight, setting the stage for triple digits the next few days.
Friday is shaping up to be the hottest day of this stretch, and we could even see a few records tied or broken, especially on the plains. Denver, for example, could break the record high of 99 degrees for June 20. Expect dry, sunny skies with very little breeze to offer any relief. It’ll feel like the middle of summer, and with very little moisture in the air, it’ll be a dry heat—but hot is hot. A Heat Advisory is in effect from 11am-6pm for Friday and Saturday for temperatures between 100-103 degrees for the Front Range and the plains. A Red Flag Warning is in effect for the western half of Colorado for Friday as well for high fire danger.
The weekend stays dry and hot, with little change expected through Sunday. Moisture levels remain low, especially across the western parts of the area, with a slight uptick in humidity toward the far east. Rain chances will be virtually non-existent through Sunday, so don’t count on anything from the sky to cool things off.
By Sunday afternoon or evening, a cold front is expected to slide in, depending on which model pans out. This front should finally break the heat and introduce a shift toward cooler, slightly wetter weather early next week. The ridge of high pressure that's been cooking us will move east, allowing for some changes in our pattern. Temperatures will dip closer to normal, and we’ll start seeing some more typical early summer conditions.
Starting Monday, expect more cloud cover, cooler highs, and increasing chances for afternoon and evening storms, especially from the Continental Divide eastward. There’s a decent bump in atmospheric moisture and energy, meaning some welcome rain could be on the way. The heat won’t vanish completely, but it should be a more manageable kind of warm as we roll into next week.
