Eastern Sierra Weather

My friends… The monsoon will intensify this week as another surge of moisture and troughing pattern impacts California. Beginning tomorrow, afternoon thunderstorms will be somewhat widespread over the Sierra, lasting until Friday. Wednesday and Thursday look the most active right now.

On Wednesday night when the trough builds in, much lower temps will arrive, but thunderstorms may remain more active through the night, including an elevated risk of dry lightning strikes along Sierra Foothills areas and along isolated coastal areas.

The exact placements of the heaviest downpours will be hard to predict, but the usual risks are associated with this pattern: strong rainfall, hail, lightning and thunder, gusty outflow winds, and localized flash flooding. Outdoor enthusiasts are advised to watch the sky and be prepared to descend before thunder roars!

The trough should bring in substantially lower temps. Longer range, the monsoon looks likely to temporarily retract, while a flow pattern favorable for moisture transport into the Southwest remains established. This could occasionally lead to more surges of moisture into the Eastern Sierra… Time will tell!
