Hi Gang,

If you live on the California or Oregon coast it seems like a regular day with dense fog at dawn. But above that fog and in the eyes of inlanders it is an atypical day with high thin clouds from the Sea of Cortez overhead from San Diego to the Columbia River Gorge.

So take a look at the image below and blog from dawn today!

The upper high pressure at ≈18,000 feet that has brought a lingering heat wave to the west coast is also sweeping up moisture from the more tropical waters near Baja.

These clouds will weaken the pressure gradient to the Central Valley, Southern California Deserts and the Columbia Basin taking the edge off the wind at many launch sites in Southern California, San Francisco Bay Area and The Gorge.

Far more importantly, these clouds bring a risk of thunderstorms to the Cascades, Sierra and California coast range for the next few days, especially this afternoon.

Given the winds, during this heat wave and the very dry vegetation this is low confidence, yet potentially high impact forecast for fires in California and the Pacific Northwest.

For the Gorge the Cut-Off upper low to our west at ≈18,000 feet adds to the moisture and instability increasing the risk.
