Triple-Digit Heat and Wildfire Smoke Expected in Colorado as Monsoon Fades
• Colorado is bracing for a significant shift in weather patterns as the monsoon season temporarily shuts down. A strong Southwest heat dome is moving into the region, bringing triple-digit temperatures to Boulder and Denver starting Sunday, July 30,
• This heatwave is expected to challenge daily record highs, with temperatures potentially exceeding 100°F (37.8°C). Additionally, wildfire smoke from the Pacific Northwest is forecasted to infiltrate the area, leading to reduced visibility and elevated ozone levels. The drying trend is already evident, with water vapor imagery showing drier air moving into Colorado. While isolated storms may occur Thursday and Friday, moisture levels will drop below normal by the weekend, effectively halting precipitation. A brief cooldown is anticipated early next week as a cold front moves in, but the heat may return shortly thereafter.
Impact & Risks
The upcoming heatwave poses risks to residents in Boulder and Denver, particularly those sensitive to extreme temperatures. Daily record highs are likely to be challenged, with temperatures exceeding 100°F (37.8°C). Wildfire smoke from the Pacific Northwest will degrade air quality, increasing health risks for individuals with respiratory conditions. Air Quality Alerts are already in effect and are expected to persist through Monday. Visibility will decline as smoke thickens, and elevated ozone levels may exacerbate health concerns. Outdoor activities should be limited during peak heat and poor air quality periods.
