Our streak of 90-degree heat continues for the Denver metro area as highs reached the low to mid-90s over the Denver area and eastern plains.
This streak will end on Saturday as cooler air moves into northern Colorado.
⚠Flash Flood Watch⚠ Substantial monsoonal moisture in Colorado will generate storms that could produce flash flooding over a large portion of central and western Colorado. The watch is in effect from 11am to 9pm today. #COwx pic.twitter.com/McLfyvzNHO

A cold front will slip across northern Colorado by early Saturday. This will bring slightly cooler temperatures and another round of thunderstorms with locally heavy rainfall for the mountains and foothills and scattered thunderstorms for Denver and the I-25 Corridor. The eastern plains will stay a little drier but will not be as hot.
Flash Flood Watches and Warnings are in effect for many of the burn scars as spots heavy rain will likely create local flash flooding. A Denver7 Weather Action Day will be in effect this weekend due to the likelihood of heavy rain in the mountains.
There is an elevated threat for flash flooding in every recent burn area today. Please have a way to receive warnings and have evacuation plans if you will be in or near a burn area today. Debris flows can travel well outside of the area of heaviest rainfall. #COwx pic.twitter.com/tVJFcph3zB

The cold front will stall across central Colorado and bring cooler, more humid air to Denver and the eastern plains through Sunday. The front will hang across the mountains, but more monsoon moisture will pour into the state from the southwest. Expect a good chance for locally heavy rainfall and possible floods and mudslides in the mountains.
Hotter weather will return to the state early next week. There will still be scattered thunderstorms each day for the higher terrain, but Denver and the I-25 Corridor will have lower rain chances and higher temperatures.
A note on the air quality - recent rains have helped to clear much of the wildfire smoke out of our skies, but only temporarily. Next week will turn smoky and hazy once again.
