Weather may have been boring, but at least tonight's sunset was not boring.  

Beautiful clear day today, went for a pleasant walk.

I ended with 1.34" shortly before midnight. I'm more than satisfied with that. Drove up to Anza east of Temecula earlier today, snow is still on the ground above 3200 FT. Very cold and windy up t

Drizzling here right now, almost enough to wet the ground.

NWS is sounding optimistic about next week's storm, which is now trending much wetter than in previous runs. We'll see.

Only had a trace of drizzle yesterday and nothing so far today here. I love this gloomy gray weather though.

0.09" now for the day.

Nice, looks like you guys in Orange County lucked out. We've had cloudy skies all day but no rain anywhere inland, except for Hemet which randomly picked up 0.11".

Rain stopped here an hour ago, I'm at 0.17" now. Today has been our first day of measurable rain since exactly one month ago.

Sun has been out for a while now, some scattered clouds but rain totals are unimpressive so far. My total of 0.17" is the highest in my area as of this afternoon, with many locations further north having still not recorded any measurable precipitation at all.

But according to the latest NWS forecast discussion, the best may be yet to come:

Quote

Another, colder punch of air will dig into the trough position tonight, reigniting shower development into SoCal. These showers will be more convective and will be capable of increased rainfall rates. (See Hydrology section below) This disturbance will strengthen as it moves south and help to close off a low pressure center over SoCal Tue afternoon. The cold air aloft and cyclonic flow will support further shower development, and possibly even an isolated thunderstorm or two near the mountains before the system moves rapidly east on Wednesday.

It was a reverse clearing day, with the Inland Empire cloudier than the coast.

That looks like the 241 just south of the Chapman Ave / Santiago Cyn interchange.

I don't want to call it too soon but this storm looks like it was a major bust for nearly all of Southern California, with many areas having not received any measurable precipitation at all through this morning and any additional chances reduced to virtually zero.

And to add insult to injury, later this week we have this to look forward to inland:

.FRIDAY...Mostly sunny. Highs 95 to 100.

One random downpour earlier this afternoon added an additional 0.12" to my total, while the nearby Murrieta station got 0.20" from it. It seems to have missed the rest of the valley entirely.

Much warmer today, and not a cloud in the sky. It's a beautiful day but I am sad that the gloomy cold weather is gone.

Around midnight I had stepped outside to find it actually drizzling here, although not enough to wet the ground.

At my office (NWS Phoenix) we cover Imperial and Riverside counties. I've been watching temperatures creep up out there the last few weeks. This week looks like mostly mid to upper 90s. Pretty boring but comfortable for those areas.

Do you and others at NWS Phoenix see signs that we may have a more active monsoon this summer? I have been reading some hints on this possibility recently, but I wanted to see what your take is on it.

Much cooler and breezier today, but surprisingly Laguna Beach was not that cold with clouds thin enough to allow some of the sun's warmth through.

Actually more breezy inland than at the immediate coast.
