The onslaught of storms that have marched into the western United States has undoubtedly created headaches for travelers and residents at times, but it has also proven to be very beneficial in building up an expansive snowpack across most mountain ranges in the region. Looking ahead to the final week of 2021, the cold and unsettled weather regime is expected to continue.
Snow, snow, snow!
The folks at UC Berkeley’s Central Sierra Snow Lab have been tracking the fluffy white stuff and predict that Christmas will be the snowiest day of the week.
We may not be getting a White Christmas this year, San Diego, but it will certainly be wet.
Back-to-back storm systems — one fueled by an atmospheric river — will bring rain, gusty winds, chilly temperatures and potentially some light mountain snow to San Diego County this week.
While California comrades to our north saw stormy weather starting as early as Tuesday, the first storm system is expected to reach San Diego County on Thursday.
Light to moderate precipitation in Southern California on Thursday may pave the way for a much stronger Pacific storm early next week, forecasters said.
Thursday’s drizzle is expected to deliver about a quarter-inch of rain to the Los Angeles area — only slightly more than the rainfall totals earlier this week — and taper off by the early evening.
A pair of storms are on their way to Southern California this week and will bring the region a chance of showers on Tuesday and Thursday.
Above-average temperatures are expected on Monday, but clouds will begin to increase later in the day as a weak weather system begins to move over the Southland.
Forecasters are calling for a chance of rain Tuesday afternoon, with only about .10 of an inch expected.
With just hours left to go in this month — and no precipitation in the forecast for Tuesday — downtown Los Angeles is set to experience its first rainless November in almost 30 years, according to the National Weather Service.
The 11th month of the year is typically not a wet one for the area, with downtown’s average just a hair above three-quarters of an inch on average, NWS said.
However, it’s still unusual for there to be no precipitation at all. In fact, that hasn’t happened since 1992, weather service data showed.
A weak atmospheric river rolled through the San Francisco Bay Area early Tuesday, dumping more than 2 inches of rain in the Marin County community Kentfield, nestled in the shadow of Mt. Tamalpais, but giving little relief to the drought stricken South Bay. Rainfall totals over the last 24 hours depended entirely on what zip code you lived in. The National Weather Service said as of 5 a.m., 2.21 inches had fallen in Kentfield, 1.57 inches in Santa Rosa and 1.66 inches in Mill Valley.
When a fierce early-season storm drenched parts of Northern California last month, some experts said it was in the nick of time.
Reservoir levels were critically low. Soils were parched. Fires rampaged through dry forests.
There was general consensus among climate experts that not even the record-breaking downpour would end the two-year drought plaguing the state. There was too much of a deficit, and a single storm — even of biblical proportions — would not be able to solve it in one fell swoop.
After a brief interruption for some rain late last month, the Los Angeles region is back to its regularly scheduled programing. In November, that means little or no rain.
For those hoping for more rain, the prospects aren’t good, as the National Weather Service puts it. The long-range models look dry into early December.
Not that L.A. gets much rain in November. The monthly normal for downtown Los Angeles is 0.78 of an inch. Downtown normally receives 0.58 of an inch of rain in October, but got 0.71 of an inch, putting L.A. less than a quarter-inch above normal so far for the rainfall season.
An “atmospheric river” stretching across the Pacific Ocean north of Hawaii is expected to bring strong winds and heavy rain to central and northern California starting on Sunday, with San Diego experiencing lighter precipitation on Monday.
The National Weather Service expects between 2 and 5 inches of badly needed rain in the higher elevations of Northern California with flash flooding possible.
