Not sure I would say pouring. We have not met the meteorological definition of a wetting rain(.10). Anecdotal data.. not wet under the trees. Very light showers since this am… totals are on the lean side. Some convective showers elsewhere but not in Grass Valley, Nevada City…or up the 80 corridor.

Yes not quite the forecast rainfall, Hard to see south of the border on these storms moving up, they lose a lot of moisture moving into the cooler waters. San Diego County, hit and miss showers, .15 in Alpine in the foothills, Some places Mountain (Palomar) got over an inch, most places .02 to .50 definitely not a season ending rain.

Mixed bag this week. The low which brought the cool and humid weather to the state has finally exited the state. In its place a moderate ridge will build in. With that moderate heat will return with some dry air and offshore flow. The ridge is not exceptionally strong and while the pressure gradients look impressive the high is placed far enough from the state to keep wind speeds on the lower end of this type of event. Temps should hit mid 90’s in the valley and perhaps flirt with near 100 in the north end of the valley.
Winds will turn offshore and move downslope beginning Sunday night. It looks like max wind speeds will be in the high teens to low 20’s in the valley. Terrain enhanced wind speeds in the typical places like Jarbo Gap could be higher.
RH will lower and dry out especially when compared to last week.
Mid week another low comes into the California. Remnant tropical moisture will be entrained into the low and arrive in the south as early as Tuesday night and Wednesday am. This pattern will look and feel similar to last week but with a stark difference. Right now the models do not take this feature much beyond the Bay Area before it moves east. The wrap around effect could bring some showers to the Central Valley especially for the areas south of Sacramento.
This system seems less dynamic than last week’s but still with enough moisture and energy to form some storms over terrain.
The soundings do not look overly convective, but cannot rule out a few thunderstorms for areas in the Central Valley as the moisture moves north.
We will most likely see a shift in the winds from the North to the SE as the disturbance moves through the state.
Looking out ahead we are starting to see our first potentially strong offshore wind event for the following week. While it is a week away it does line up with climate expectations for a system to clip the north state and dive down into the Great Basin ushering in strong winds behind it from the north.
Still some time to watch that progression.. for now warmer-dryer-breezier for the first part of the week-some subtropical moisture for mid week.

Just watch Mike Snyder’s morning update… might have to watch Tuesday time period for NOPs convection… more to come on that.

It’s pushing high 90s in Chico, today. I’d like to retract some of my earlier enthusiasm.
Still good burning conditions up in the black oak and pondo, though!

TGU is getting some bonus acres as we speak. Multiple spots over the lines, 4+ tankers requested, 3+ rotor in addition to the RX’s rotor.

Yes - TGU Sunflower RX has yanked its leash off. Sorry mods - my user interface for this website is messed up. I’ll make a Q&A post for your team to move this too.
