Monsoon Surge Brings Thunderstorm Risks Across Western US
• A ridge of high pressure is shifting from the Southwest into the Southern Plains, while a trough-dominant pattern develops along the West Coast, leading to cooler temperatures in coastal areas and a relative cool-down for the Interior West.
• Thunderstorm chances will increase midweek, particularly in Eastern Utah, with spotty rainfall due to dry lower atmospheric levels.
Impact & Risks
The monsoon surge will elevate the risk of flash flooding in Utah and surrounding states, particularly in areas with slower storm movements like Southern Colorado. Thunderstorms may bring heavy downpours, posing risks to outdoor activities and travel. Coastal areas of the West Coast will experience cooler temperatures, while wildfire smoke may persist in the Inland Northwest. Southern and Central New Mexico will remain relatively dry, reducing the risk of flooding but increasing fire danger. (Source: OpenSnow)
