Denver, Colorado – Temperatures will climb into the 70s and 80s by Thursday afternoon, bringing a warm, spring-to-summer transition across Utah and Colorado before a significant high wind event develops late in the period.
According to the National Weather Service and NOAA’s Climate Prediction Center, both states are trending near to slightly above normal from April 16 through April 20, with warming conditions spreading across lower elevations under increasing sunshine.
In Denver and across the Front Range, including Jefferson and Arapahoe counties, highs are expected to reach 78 to 84°F between 2 p.m. and 6 p.m., with overnight lows in the upper 40s to mid-50s. In Utah, Salt Lake City and surrounding areas will see highs in the upper 70s to low 80s along the I-15 corridor.
Conditions will shift beginning April 18 as a strong western storm system develops. Wind gusts are expected to increase to 35 to 45 mph across both states, especially along I-70 from Grand Junction through Denver and into eastern Colorado. These winds could create hazardous travel conditions, particularly for high-profile vehicles.
Mountain areas, including the Rockies and Wasatch Range, may see periods of snow, while lower elevations could experience isolated rain showers late in the period. Blowing dust is also possible across eastern Colorado plains, reducing visibility.
Residents should secure loose outdoor items and remain alert for rapidly changing weather. Drivers should prepare for strong crosswinds, especially along east-west routes like I-70.
The warmest conditions are expected through April 18, followed by a transition to a wind-driven and more unsettled pattern through April 22. Additional advisories are likely as this system strengthens across the Rockies.
