3/8 of an inch last night at my casa. 40 out when I took the pics. RH off the chart, no wind.
Fire season in the Sonora area, stick a fork in it. Unless we get some very strong north/east winds not much is going to happen. Grass is starting to really show itself and leaf litter having a harder time drying out with these shorter days. Different story for you folks south of the Tehachapi’s.

Ventusky HRRR for TUE Nov 7 8pm.

Ventusky HRRR for WED Nov 8 10am.

Mostly the same forecast as yesterday. Sundowners tonight for Santa Barbara south coast and the south exposures of the Tehachapi Mountains.

Ventura and LA, blowing pretty hard over the Gabriels overnight and in the morning, actually, and focus shifting to the eastern Transverse (Angeles and Bernadino) through midday and weakening by tomorrow evening.

The Tehachapi Mountains, looking northwest. Mark the transition between the Central Valley and the Mojave. Rugged chapparal, grasslands, oak woodlands and savannah.

Showing alignment on Tuesday. Winds from the north. Grapevine to Tehachapi Mountain.

By Wednesday afternoon, northeast winds are blowing across the ridgelines.

Not much recent fire history. Lightning burned a lot of acres in the fall of 2011.

Chins in the wind. :slight_smile:

At this time, all models bring a season ending rainfall event next week. There is a slight chance the frontal boundary washes out before moving around Pt. Conception but atmospheric river ensembles show a pretty good chance of AR making it south. The lack of fire activity across South Ops the last three seasons is pretty exceptional.

Continued blocking pattern over Canada and the Pacific NW with an enhanced subtropical jet stream over Mexico rather than the desert SW this winter could favor more cold continental airmass intrusions from the NE in a Modoki El Nino like pattern.

Variable is right. The HRRR model was predicting this to be mostly over by tonight, but instead the winds have sustained, rH took a nosedive and the Fire Watches have been escalated to Red Flags through tomorrow morning.

If it’s any consolation for surfer helo, while light to moderate offshore winds help the waves to stand up, a hard blow just makes a mess of it all.

Ventusky HRRR for THU Nov 9 8am.

These winds don’t look as strong as during the 2021 Alisal Fire, but one of the issues of fires near the water is when wind directions change abruptly near the waterline because of the way the Pacific is like to rip sideways through the channel, disrupting normal orbital patterns.

The Catalina Eddy is mostly reestablished in the channel and there will be an onshore flow in Ventura County today, with some northeasterly gusting to 25mph in the Angeles and San Bernadino Mountains.

Sun Fire may see a bit of northwesterlies to 20mph in nearby Honda Canyon and the Santa Ynez ridges in the late afternoon. Crews that are still on the fire grounds tomorrow may get to see a Falcon 9 launch from Vandenberg around 11am.

The operational GFS continues to trend drier on the storm system later this week versus the wetter ECMWF. In fact, the 12z GFS had little to no precipitation for areas east of Ventura county. The implications of this are pretty significant as forecast models show a potentially long duration and strong trident ψ Santa Ana wind event (strong pressure gradients, upper level support, & cold air advection) next week.

This is one of the most impressive if not most impressive warm front sector convective lightning storm we will ever see in our coastal waters.

San Diego just had some neat weather. That was pretty fun, Strong winds, dust, then thunder and lightning followed by 15 min of heavy rain. Most lightning I have seen in a while. Many tree fires popping up locally but rain is heavy.

Last night we got 1/16 of rain in the gauge(Sonora area). Still dry under a lot of tree and brush canopy. Further up the hill more rain. .25 in Twain Harte. Sounds like more rain coming Saturday.
Photo is looking N/NE toward Columbia area and the mountain with the sunset on it is American Camp. Stanislaus Shots would cut line off it down towards the Stanislaus River. A steep piece of ground. Been giving you folks morning pics thought I would change it up.

Yesterday storm started pretty slow. Half inch of rain when I emptied the rain gauge at dark. Last night we had a hard rain and another inch in the gauge this morning. 1.5 total for this storm, not bad. Fire season in my eyes is done here, never really got going which is not a bad thing considering the last ten years. 45 out, RH off the chart and no wind. Hope everyone has safe travels and a great Turkey Day. Looks like great weather for the next week.
Side note: very clean air this morning could see some peaks in Yosemite. It’s been awhile for that.
