Little over an hour ago Helco requested AA above the fire within 15 mins. Sounds like some tankers working the NE area

Looks like itās getting into some thicker fuels or something

In watching the instability/t-storms moving in from the SE iām wondering if the possibility of something like a āgravity waveā from outflow winds might propagate towards the W-NW and potentially influence this fire - given weāre still a ways from sun going down and this instability might persist for some time after sunset? Or is that slug of t-storms/instability not yet organized enough to create such energetic line of outflow? Am i nuts for thinking that @anvilhead @norcal74

Looks like the airshow is back. T122, T181, T86 and T85 along with 4 rotorwings and a Helco over the fire now

Yes, seems plausible because there is mid-level ascent with this easterly wave approaching. As long as the fire is burning intensely, it should ventilate efficiently with the instability.

Sonoma County just issued an all call for OD Personnel.
All staffed engines are to respond to the fire.
This is from a SC Captain.

This was just Cal Fire engines and the wet-hire cover engines.

Iām not sure that is accurate. Calfire issued an alert for all Calfire engines available in Napa to respond. Nothing for Sonoma County has been issued.

This seems odd. Did they throw Command and Control out the window and willy nilly told everyone to respond? Or was there a dispatch that sent the remaining engines in Napa. I know things have changed in 10 years since I retired, but I hope ādump the Unitā hasnāt become SOP.

Watch Duty Reported this ā All available local CAL FIRE engines have been dispatched as an additional response to the Pickett Fire, reporting to the area of Aetna Springs Rd & Pope Valley Rd, per radio traffic.ā

In watching the GOES West iām 95++% certain the energy of that air can now be seen pushing the low level clouds to the W/NW & the rippling across the top of the marine layer in the same direction, just south of SF. It ( what i believe is the push of air generated by the T-cell outflow & inertia) appears to be working its way north. Just fyiā¦

This is why WD is very ānot trustingā for me because I havenāt heard such a dispatch yet.

Donāt you think that is just vigorous on-shore flow? The smoke on the surface (west of the plume) all the way up to the alto-cumulus clouds seem to be in stout WSW wind. There is definitely a mountain wave.
Those of us on the eastside of the Sierra see this kind of thing all of the time.

Concur, itās most visible from the Berryessa Peak camāthe undulating plume hugging the surface is a giveaway.

You just about have to vet everything you read/hear these days.

Im seeing (it could be shadows/artifacts of GOES) what looks to me to be a push from the se towards the w-nw, offshore. And to me it was/is looking like the column was (in the current loop) recently also skewed toward the nw from its mostly steady northward drift. But, im a stooge just trying to learn and could be way off. Hopefully my tone/words arent sounding like iām trying to be an expert - in hindsight i need to leave my feeling of certainty out of the post for complex Wx stuff like this.. I hear & understand what you are describing and there is no argument from me on that.
Edit: trying to say i believe more than one force of Wx is acting upon the local environment..
