Denver, Colorado – Scorching heat and scattered thunderstorms will dominate Colorado’s weekend weather as highs climb into the 90s and storms threaten travel by Saturday afternoon. A summer weather alert is in effect as lightning and 50 mph gusts could hit the I-25 corridor, including metro Denver and Adams County.
According to the National Weather Service in Boulder, storm chances will increase through the day Saturday, with isolated lightning, brief heavy rain, and small hail possible. The strongest cells could form over the eastern plains on Sunday, bringing a risk of large hail and damaging wind gusts, especially east of I-25.
Saturday (July 5) will see a high of 92°F in Denver with a 20% chance of afternoon thunderstorms. Winds will be light but could gust near 15 mph.
Sunday heats up to 91°F with a 30% chance of afternoon storms. These may turn severe in places like Morgan, Logan, and Washington counties.
Travelers should monitor conditions closely, avoid open fields during lightning, and stay hydrated in the heat.
