Sunday's storm could be dangerous; freeze line above 8000' would melt the snowpack; it happened during last week's AR.

Quite a storm today, though I was expecting even more heavy rain. After a few hours of quiet, just had another heavy shower.

 

Heavy rains today may have kept away some protestors.

Yesterday's storm was not as strong as I expected, though there were some periods of heavy rain. The creek in the park near my house was not that high. Nothing like when we had a storm that dropped 7 inches of rain in one night and washed out the sidewalk about 5-10 feet above the creek.

2.69" fell here in Orange from late Wednesday night to Friday for a season total (beginning July 1) of 12.64". I emptied my rain gauge just in time tonight as it was just beginning to sprinkle when doing so

Sun rises in Utqiaġvik, Alaska (formerly known as Barrow) for the first time in 2017. The sun will be up from about 1:18 PM to 2:00 PM. At solar noon, the sun will not be fully above the horizon.

 

Meanwhile in Lake Forest, sunset has changed from 4:46 PM to 5:12 PM since Winter Solstice while sunrise has changed from 6:51 AM to 6:52 AM. Solar noon has changed from 11:49 AM to 12:02 PM.

 

Rain has begun, but so far it's very light. Hope to see it get heavier throughout the day.

Our rainfall amounts are quite similar. We could end the month w/ rain totals close to average annuals for the rain year especially if today's storm reach forecast amounts [2-4"].

 

January: 6.38

 

Rain year: 12.94

So far rainfall intensity has been below expectations. Would not be surprised if we got less than half the forecast totals. Storm does not look too impressive from the satellite.

Sustained, heavy rain here this afternoon. 1.43" and rising. I had forgotten the name of this website so I couldn't get back on it  :rolleyes:

 

I've been away for the last couple of weeks as my hard drive failed (hadn't backed it up in a year like the idiot I am), and I had a professional data retrieval company in Irvine recover the data for me (costly but worth it!).

So far we have picked up just over 1.7" with the current storm.  The previous storm produced 2.7" and out monthly total is now over 8".  The soil seems to be finally getting saturated in the garden as even a light rain is causing some ponding.

As much as I'm excited by the 2.72" we got in Fullerton, I'm extremely disappointed by how this storm ditched San Diego. Only 0.18" with the rain already moving out.

It was an interesting morning today.  I got awakened to a tornado warning for Santa Barbara county on my phone this morning.  Although I was not near the warning area there was a brief period with heavy pea size hail around 6:45 am.  There was still some hail persisting, unmelted in one of my plants located in a shaded area, this afternoon around 4:30 pm.  

 

January rainfall total around 9" and Season total at 14".

 

There is finally some runoff into the Gibraltar and Cachuma reservoirs in Santa Barbara county.

We had one loud bang of thunder last night and an intense downpour that lasted for a few minutes around 4:45 AM. The rest of the day had some occasional showers, but no more thunder. Right now it has mostly cleared out.

 

Still hoping for San Diego to get some more showers tonight and tomorrow.

Having hail stay around for most of the day is a real treat. I recall the same phenomena several years ago. Frost is very likely for the next few nights. Many areas are in the 30's this morning especially inland valleys. Coldest minimum this month/ season here.

It's a beautiful morning with sunrise finally a few seconds earlier than on Winter Solstice. We have gained 29 minutes of daylight in the afternoon. After February 11, however, sunrise will be changing at a faster rate than the sunset.

Lots of snow on the San Bernardino mountains, but in Lake Forest, they are mostly blocked by the Santa Ana Mountains.

Back to boring weather for a while. Since the atmospheric river that gave Orange County and LA County so much rain with the last storm mostly bypassed San Diego, we will need to hope for some storms focused on San Diego County.

Nice to see recovery of rain deficits but southern most Santa Barbara and much of Ventura county are still in extreme drought. Overall a wonderful improvement for California. Some very cold morning temps but not even close to records; frost wasn't as widespread as predicted.

We still can really use more rain in Santa Barbara County.  Our main reservoir, Cachuma is still under 15% capacity.

3.70" fell here in Orange with this last storm, bringing my season total so far to 16.34". It is nice that we are having a break from the storms for a little while, but I hope we see more storms sometime in February, and hopefully the on and off wet pattern will continue into the spring! If the wetness continues, then further reductions in the drought are likely.

There has been a bit of discussion, as you know on WW, concerning the corridor of deepest moisture during last week's rainfall. Orange/ LA counties benefitted nicely. Later next week another storm should provide more rain/ snow primarily in NorCal.

The northwest corner of LA county is also in extreme drought. Basically Mojave desert, that area can make up winter rain deficits in a single summer thunderstorm.

Barometric pressure readings have been very high in CA today with strong surface ridging. Readings were in the 30.40s and 30.50s in many areas. There were readings as high as the 30.70s and 30.80s in NV, ID, and eastern WA as well, closer to the high's center. This is the same high that is helping to fuel our strong Santa Ana wind event.

Wind hasn't been particularly strong here compared to parts of the San Fernando valley/ IE and Orange county. The San Gabriel mts often block/ greatly modify santa ana winds depending on the location of high pressure.
