Pacific winter snowstorm this week
In a 12 months when snowfall in California has already exceeded yearly totals, a Pacific winter storm has the U.S. West Coast in its sights in late February 2023. Flooding rainfall, wind, and snow measured in ft are in retailer over this weekend for a lot of California and the West Coast states.
Daniel Swain – a local weather scientist at UCLA and the Nature Conservancy – said throughout an internet presentation on Tuesday morning (February 21, 2023):
Nearly all people who lives in California will in all probability be capable to see snow, a minimum of within the close by hills.
The storm is part of a remarkably lively climate sample over the U.S. this week, bringing climate extremes in all corners of the nation.
I’ve NEVER seen this earlier than. A blizzard warning has been issued for the mountains round #LosAngeles and Ventura County. As much as 7 FEET potential on the highest elevations. 2-5 ft above 4,000 ft doubtless. Unbelievable. #CAwx #snow #wxtwitter pic.twitter.com/GMa0zoclNR

California’s loopy winter in 2022/23
This week’s storm is simply the most recent in an extended string of West Coast storms this winter. California has skilled harsh winter situations with half a dozen comparable storms over the previous couple of months. Though flooding and energy outages have been issues for a lot of, the winter storms have introduced badly wanted drought aid for the mountains and farmland.
Since October 1, Central and Northern California has measured 200-300% of its regular rainfall in that interval, wiping away a drought of over three years.
Snowpack can be above 150% of regular for this time of the 12 months. Excessive snowpack is especially vital for the watersheds within the Sierras that offer thousands and thousands with consuming water and invaluable irrigation to the farmland in Central California.
Present winter storm anticipated to begin immediately
The tough climate is predicted to start Wednesday and final by the weekend. The storm system is taking an uncommon path, drifting due south from Washington in the direction of southern California. Because it slowly drifts, many areas will see an prolonged interval of heavy snowfall, probably lasting greater than 4 days. One-two ft (0.3 – 0.6 m) of snow is formally forecasted to fall by the weekend. A number of inches of rainfall will fall in areas too heat for snow, resulting in flooding issues after an already-wet winter season.
?Heavy low elevation snow with harmful journey impacts anticipated tomorrow – Friday. Snow ranges will fall to 1,000-2,000 ft tomorrow, with snow ranges all the way down to ~500 ft to the northern Sacramento Valley ground early Thursday morning & Thursday night time – early Friday. #CAwx pic.twitter.com/lZv4ebs72T

Snow even in San Francisco space
Snow is predicted even in the San Fransico Bay area on Wednesday because the chilly core of the storm drifts south. Accumulating snow close to sea degree is sort of uncommon within the Bay space. The final measurable snow in San Fransisco was February 25, 1996. Though accumulating snow will not be anticipated for town heart with this technique, forecasters are calling for snow-capped hills at elevations above 500 ft (152 m). Excessive-resolution climate fashions say that just a few snowflakes should still make it all the way down to sea degree.

Sturdy winds
Sturdy winds will even accompany the storm system. The Nationwide Climate Service forecast is looking for 70 mph winds and certain blizzard situations within the excessive elevations on Wednesday.
CA/NV Drought Replace
Current storms reversed 3-year precip deficits in areas of coastal SoCal, central CA and the jap Sierras in NV.
However NorCal, SE CA and components of NV did not get as a lot. And groundwater ranges and snow runoff into reservoirs are TBD.https://t.co/HRX64fEBp4 pic.twitter.com/BdBcB5z4Gu

Try the present #snowpack (left) in comparison with this time final 12 months (proper) from @USDA_NRCS. Throughout many of the West, situations are trying a lot better, particularly in California and the Nice Basin. Many watersheds are near, or above, the long-term common. #drought pic.twitter.com/9MIB2H3FR3

In the meantime, elsewhere within the US
The lively climate sample is stuffed with reverse extremes throughout the USA. Whereas the West Coast is hit with winter situations, a blizzard is ongoing within the Higher Midwest, and record-breaking spring heat is spreading by the Southern USA and Mid-Atlantic. This heat has continued practically the entire winter east of the Mississippi river which has led to record-low snowpack from North Carolina to Maine.
