* TIMING: LATE TONIGHT THROUGH DAY BREAK SATURDAY...THEN AGAIN SATURDAY AFTERNOON AND EVENING.
Guess there is going to be more to this storm than I thought.
Yep - Northern Calif has been getting a real pounding but we need every drop and snowflake we can collect. The Sierras are still getting hit, with wind warnings for winds over 90 MPH at times. More to come too, the way the forecasts read here.
See Wunderground.com for great weather info!!!
Does this mean we won’t get snow? Well, Not only do I have this to deal with I have a chicken and two cats living together under my shed in the side yard. Do chickens like snow.
Apparently so. We are starting to get the lead sprinkles of the rain now here in Western Riverside County, and the breezes are increasing. Cloud cover is thick now where it was quite broken up just an hour ago.
Chickens can adapt,...cats might complain.
Raining off and on here on the Westside as well. They said parts of the San Fernando Valley could get snow, how awesome would that be!
Bring it on .. Shovel ready!
Unfortunately, snow in the San Fernando Valley does not look as likely now that the cold front is forecast to move through the area faster than anticipated. Most of the cold air will arrive too late when much of the moisture is already well east of the area. You never know, though!
AFAIK, the snowline in northern California is still expected to drop to 100 feet. This isn’t a Pineapple Express. It’s coming down from Alaska.
DANG!!! You guys get all the good weather and all we get is light rain and some snow. Our weather guy said that the cold front coming down the coast was tying into a moist stream our of the Pacific and this one is hitting you instead of the north coast...
It's all the puffy stuff of the coast.. lots of instability lays ahead
Enjoy it if ya can!
an arctic blast.. I can’t wait to run the dogs in it.
I grew up with the cold stuff...staying away from it in my later years and it is coming after me.
By Heather Buchman, Meteorologist
The last time it snowed in downtown San Francisco was 1976.
As AccuWeather.com Western Expert Ken Clark has been stressing, this storm is a "big deal" for California.
Major disruptions to travel through passes, including all those leading into and out of the L.A. Basin, are expected with this unusually cold storm. The snow will be coming just before the Oscars kick off Sunday.
Travel-snarling snow will not be limited to just California, with parts of Arizona, Nevada and states farther east set to get blasted this weekend as well. Snow could even fall at the Accenture Match Play Championship at the Ritz-Carlton Golf Club in Marana, Ariz., this weekend.
More details on how the storm will impact these southwestern states are provided in this news story.
I fled FResno County to come to Eureka in 1954 to escape the oppressive heat which I did but the tradeoff was I had to acquire Web Feet to navigate the mud here...
Web feet....do you have to use the garden hose to clean them off before you go inside?
Have you still got that old dog sled Norm?
A very cold storm now in the Northwest looks still on track to bring California, and other areas, a rare taste of the white stuff other parts of the nation take for granted. This storm could be a once-in-20-or-30-years storm for parts of California for how cold it will be and how low accumulating snow will get. By Friday in the north and late Friday night and Saturday night in the south, it will be almost as cold as it can be. It is rare to see 500 mb temperatures dropping to around 35 below zero C around the Bay Area and 32 below zero C near Los Angeles. 850 mb temperatures will fall to a ridiculous 8 below zero in the north to 4 or 5 below zero in the south. This will be a no-frills update. I will give detailed forecast by region with text only.
Snow developing from north to south Thursday and Thursday night with gusty winds and heavy snow for about a 12-hour time period. Additional snow likely Friday into Saturday into Saturday evening but more showery in nature while still being locally heavy at times. Accumulations above 6,000 feet: 18 to 36 inches with blowing and drifting. Snow levels will drop to the lower foothills from north to south Friday and Friday night, and 6 to 12 inches is likely above 3,000 feet with locally higher amounts; 3-8 inches can fall down to 2,000 feet and a few inches are possible down to 500- to 1,000-foot level. Snow will end Saturday night but it will remain very cold through Sunday with snowcovered and icy roads likely to remain well beyond the ending time of snow.
Part way through the winter season, and in the Southwest the rainfall season, and it's time to check to see how things are doing as far as precipitation and snowpack. In general, pretty darn well. In areas that it was feared were going to be in a drought year, the numbers are anything but droughtlike. This should make water managers smile a little, and it may mean more money in your pocket next year than if there was a drought.
The following is a map of the snow depth departure from normal all across the West.
Areas of blues and purple have above- to much-above-normal snow depth, and the yellow and oranges are below. As you can see, a large percentage of the West is in the blue. This is especially true for the Sierra, the Wasatch range, and a large portion of the Cascades. There is an area of the northern Cascades that has below-normal snow depth. The more widespread area of lower-than-normal snow depth is in the northern Rockies from Montana and eastern Idaho to northwestern Wyoming. The good news in some of these areas is that the rest of the winter should be kind to you for additional snowfall, and negative departures should diminish.
For California, having had major water woes in the last several years, the mega storms of December brought a ton of snow and rain. The chart below shows a breakdown of the northern, central and southern Sierra showing snow water equivalent and the percentage of normal to date, also compared to what should be normal on April 1.
Will look around.
Good luck to anyone needing to go Reno today. Hwy 395 just closed between Lee Vining and Bridgeport due to blizzard conditions and part of I-80 between Sacramento and Reno closed due to whiteout conditions. Dumping snow in Mammoth right now.
More from Clark's Blog:
I do not have a lot of changes to the long posting of yesterday for the weather from Thursday night through Friday in California. You can check the original post by clicking here.
But there are some changes, especially for Southern California. The cold front dropping south late tomorrow and tomorrow night will have more southwest flow ahead of it than was forecast yesterday. This will probably push up snow levels ahead of that front tomorrow night. They are likely to climb to 4,500 feet or so on south-facing slopes, while on north-facing slopes the snow could fall at levels from 500 to 1,000 feet lower. Those snow levels will start to fall again late tomorrow night and Saturday morning, reaching the levels I talked about yesterday by Saturday midday and afternoon. Rain ahead of the front is also looking to be pretty heavy for a time, mainly later tomorrow night around Los Angeles, and very late tomorrow night through midday Saturday in San Diego.
After California, the next stop for the very cold storm will be Arizona. Arizona will also be hit with very low snow levels and accumulating snow in places it does not happen every winter.
The greatest precipitation moves in from west to east late Saturday and Saturday night and continues into Sunday central and eastern sections before diminishing from west to east. Snow levels begin between 5,000 feet north and 6,500 feet south but fall rapidly tomorrow night to 2,000 feet central and north to 3,000 feet southeast, putting snow showers into parts of the Tucson Metro area.
Accumulations above 6,000 feet from the in the northern mountains will be 12 to 24 inches, with 6 to 12 inches above 7,000 feet east-central and southeast
100 or 1000 feet????
Phoenix race Sunday could be a bit rain delayed and chilly either way.. fingers crossed..
I wish.. the boy poodle could pull it by hisself.. he thinks he’s a husky.
The weatherheads had mentioned snow to sea level at one point, and Yes, 100 not 1000. 8-o
"No snow so far, just regular old rain

Wondering where the all the snow is? You might have to wait a while, and head to the hills to see any at all.
The rain that fell over the Bay Area overnight and early this morning was courtesy of a strong low pressure system. But the temperatures aren't low enough for snow to fall, at least not yet.
The snow level won't drop to 1,500 feet throughout the region - and 1,000 feet in the North Bay - until it gets colder, which might not happen until "very late this afternoon," said Bob Benjamin, a forecaster with the National Weather Service. "As the cold front comes through, the air mass will become unstable," Benjamin said. "There will be showers and the cold-air temperature will begin falling off." Benjamin said any snow that does fall will be "showery in nature" rather than steady ..."
“Chickens can adapt,...cats might complain.”
LOL! That’s funny! Actually, the cats will certainly complain, but the weather will only be an excuse.
Wow....here’s PRAYING it DOES come...AND while the dawg and I are still awake. She was in it once and LOVED it!!!!!!
Get your Blankie ready....or your snuggie...
Alright, Thud. MAKE IT SNOW for us! :)
I’m NOT a wuss like some people who shall remain unnamed. Why, I’m at the office with my shorts and flip flops on AND!......I have this bridge..... :)
Might are put away
I am wearing one of those hooded sweats.
Gotta keep the electric bill down...damn it is expensive.
I remember the first winter we moved out here from the midwest....and how I laughed at everyone for their winter coats....
...till the next winter.. :)
I wanted some snow.
(Going to pout in the warm corner)
Snow once every 40 years or so, is about as often as I like to deal with it :)
We’ve had only a very light rain here in Eagle Rock. Nothing like the warnings describe....hubby keeps scratching his head and wondering when the “ storm “ is coming.
How about the rest of you?
wow Norm~~ Impressive!
It is looking very dark in the west out my little window....Cold and Wind seem assured...rain and snow will depend.
AW tubebender, what you need is more wet snow, rain,gusts and a couple bottles of cool Rainere (?) beer.
Wow, we just got ice pelleted, tiny fellars we’re the only red on the radar in the bay area. (beside bezerkeley)
Glad this event isn't earlier in the winter, because if the surrounding Santa Rosa Mountains got snow, we'd get the frigid wind effect for many, many days...............but we're predicted to be back in the mid-upper 70's by midweek.
I'll take this one as a mere photo op tomorrow or Sunday morning.
Ice pelts? wow... so it is happening for reals! Hmmmm glad we have a nice fire going here tonight!
I’m not sure we will get any flakes here, it’s 45 right now and we may make it to the low 30s,, , the pellets sure drove the poodles nuts.. two spurts of ‘em so far.. looks like a lot of small cell activity as this stuff blows thru..
