Denver woke to hazy, smoke-tinged skies on Wednesday, June 24, with temperatures holding in the low 60s and a light southeast breeze. The smoke aloft will keep the morning looking a bit washed out, but the day is still on track to warm into the upper 80s. The main concern comes later: a late-day severe storm threat that could throw a wrench into evening plans.
Late-Day Severe Threat
Scattered to numerous strong to severe thunderstorms are expected Wednesday afternoon into the overnight hours, with the highest threat across the I-25 corridor and the eastern plains. The Storm Prediction Center has placed parts of the central High Plains in an enhanced severe risk and warns storms could produce very large hail and damaging winds. In some guidance, hail up to 3-4 inches is possible. Slow-moving storms may also drop brief, intense downpours that could trigger localized flash flooding.
What To Expect Today
Mostly sunny skies and a high near 88°F are on tap for Wednesday, with light east-southeast breezes turning variable later in the day. The National Weather Service says scattered showers and thunderstorms should become more widespread late Wednesday into Wednesday night, and the flash-flood concern will increase if storms stall over the same areas.
A Red Flag Warning is in effect for mountain zones from 11 a.m. to 6 p.m. Wednesday because warm, dry, and breezy conditions could produce isolated dry lightning.
Smoke And Air Quality
Smoke from wildfires to the west will hang overhead and keep the sun filtered, with reduced visibility at times, especially at higher elevations. While near-surface smoke appears light, anyone with respiratory issues should be ready to cut back on outdoor activity if they notice irritation or trouble breathing.
Commute And Event Impacts
If you have evening events or travel planned in the roughly 9 p.m.-3 a.m. window, be prepared for quick changes. Large hail, damaging gusts and sudden downpours could lead to road closures and flight delays. Move vehicles under cover when possible, steer clear of flood-prone underpasses and give yourself extra time if you need to be on the road.
How To Stay Safe
Keep an eye on local watches and warnings, head indoors at the first clap of thunder and never drive through flooded roadways. If you are headed into the mountains during the Red Flag Warning, avoid campfires and follow guidance from local land managers.
