Weather Key Points

    Periods of rain and mountain snow showers will develop first for coastal areas Wednesday, spreading inland at times through late week and the weekend. Much of the precipitation will be light, though some travel impacts are possible for the Sierra and far northern California mountains, especially Thursday through Saturday
        The heaviest snowfall will likely occur Friday across the Cascade and Siskiyou mountains
        Moderate to locally heavy rainfall may be possible for the northwest corner of the state over the weekend
    Drier and warmer weather will develop for much of the state early-to-mid next week, though periods of precipitation will likely continue across far northern California

We are actively troubleshooting an issue with stale/old information on some of our online products as well as our local phone tree and phone forecasts.  We do not know when the issue will be resolved but we are working on it. 

The temperature at Long Beach Airport (KLGB) has not been reporting since Nov 23. Out technician went to the site and determined a part has failed.  A replacement has been ordered, but the particular part is on back-order.  As soon as the part arrives, we will fix the issue but unfortunately it is unknown when that will be at this time. 

If you have any questions or need any information that is old, you can call us 7 days a week from 8am to 8pm at 805-988-6610.

From NWS Los Angeles: Gust of 130mph (!!!!) #SantaAnaWind #FireWx #CAwx #windy

The well-advertised strong Santa Ana is well underway this 
morning with a strong offshore gradient (-7.9 Los Angeles to 
Dagget) and even more impressive offshore trends (nearly -12 in
the past 24 hours!) widespread wind gusts in the 45 to 65 mph 
range extending a bit beyond the typical Santa Ana Cooridor in Los
Angeles and Ventura County. Peak gusts to 70 to 90 mph have been 
observed in more wind prone mountain and foothill locations with 
Magic Mountain Trucktrail in the western San Gabriel mountain the 
big "winner" with a gust to 130 mph! Current wind hazards are well
placed for these winds with the end time of 3 pm this afternoon 
probably appropriate for most places outside of the interior Los 
Angeles and Ventura mountains, which should hang onto Warning 
level winds at times through Tuesday morning. Where the Warning is
allowed to expire at 3 pm, Wind Advisories will likely be needed 
through Tuesday morning or afternoon.

It might seem kind of odd or amusing, to folks outside of California, that a non-severe thunderstorm approaching a major city is a newsworthy event. But across much of coastal California, especially in the north, lightning is in most years a notably uncommon event! #CAwx https://t.co/zWYJSr6lFk

I've never seen the NWS forecast be wrong for this many days in a row before... I keep tarping the car for the predicted rain and it keeps getting put off by a day. Must be a tricksy weather pattern.

Further update: The quasi-stationary low pressure system spinning west of CA continues to confound. At this point, widespread and notably warm soaking rain event still appears likely for most of the coast from LA to north of Mendocino, but heavy totals unlikely. #CAwx https://t.co/dlauysG9T0 https://t.co/POPH8olHIJ

There is a 30 to 50 percent probability of moderate winter storm impacts in the Sierra Nevada above 7,000 feet Wednesday night and Thursday due to snow load and snow amounts up to a foot. Travel could be hazardous. If you plan to travel, consider alternate strategies. If you must travel, remember to carry tire chains, plenty of food, a good deal of water, warm clothing, and a flashlight in your vehicle.

This storm will actually come in multiple waves as a broad low pressure area develops west of CA and remains quasi-stationary for most of the week, spinning occasional spokes of precip onshore. Associated airmass now appears to be remarkably warm for a Nov event. #CAwx #CAwater https://t.co/ZqIeFUlFEB

06:42 Sunday - Some lightning in the cold front offshore, generally near Tofino, British Columbia and along a line leading south-southwest from there out about 200 km.

Additional lightning in the front well off San Francisco.

It's a moody, wet morning at #ForkedMeadow #California in the central #SierraNevada #mountains.We're up to 0.9" of rain from this storm system so far. The current temperature and overnight low is 35f. There's a chance of some snow mixed in with rain today.

After this storm system moves out of the area tonight, it's looking like five or so days of dry, cool weather.

Here's an example of how the National Weather Service - which even as late as 2022 had tweets with no alt text at all - performatively creates alt text rather than caring about communicating equitably with screenreader users, who *also* pay taxes that fund NWS.

Look closely and see the actual text in the graphic is NOT what's in the alt text field. So not only does it not do the job of alt text, it's a hassle because it means screenreader users will hear this text TWICE. #Ableism #CAwx

Imported tweet from NWS Los Angeles office. @nwslosangelesbot@m.ai6yr.org  Tweet text said "#CAwx #LOX #graphicast 
        Several hours of near-freezing to sub-freezing temperatures are expected late tonight into Thursday morning, resulting in Frost Advisories and Freeze Warnings for the interior valleys of San Luis Obispo County, Salinas Valley, Antelope Valley, Santa Barbara County inland Central Coast and Santa Ynez Valley. Temperatures as low as 30 degrees are expected in the coldest sheltered areas. Subfreezing temperatures will"

Meanwhile, in Socal, a stronger Santa Ana-type offshore wind event will ramp up fire risk much more than in NorCal. There hasn't been much rain in last 30-45 days down south, so vegetation is drier than ion north, and winds may be somewhat stronger as well. #CAwx #CAfire https://t.co/CIWG2iXaIX

Offshore winds and low relative humidity will increase fire risk in parts of CA this wknd. But important to keep in perspective: vegetation dryness is NOT exceptionally high this yr, so not comparable to extreme risk in recent Oct/Nov events. #CAwx #CAfire https://t.co/0HqLINpl1R
