Everywhere from the Coastal Ranges and west towards the coast in California is in a dramatic battle with flames engulfing anything in their path. This is a region desperate for moisture and cooler temperatures, as well as a diminishing of winds in the region. Will that relief be coming?
At 1153AM, PT, San Jose was reporting clear skies with a temperature of 71 degrees. It’s low lying valley location allowed it to be one of the few sites in northern California not reporting smoke or obscuration at the hands of the prolific fires across the region. Smoke was visible on satellite imagery north of San Pablo Bay , flowing to the southeast towards San Francisco and the north Pacific. This was in response to a strong upper level trough diving into the area through the Pacific Northwest. While it was going to bring rain and snow to those areas, it is only providing more dangerous blustery conditions to residents of the Napa and Sonoma Valleys.
The trough is on its way out of town, which is excellent news for firefighters. A ridge will build back into the coastal regions of northern California, which will have the effect of steering fire away from the more populous regions closer to the coast, though in San Jose, some slightly warmer temperatures appear to be in the offing, thanks to the emergence of downsloping flow. Unfortunately, with the arrival of the ridge, winds likely won’t fully subside through the forecast period.
