Getting Dialed

Good coyote! Watching Boreal's groomers
Funny, my sleep schedule this season is shaping up as a two part affair...fall asleep during the Noon News, wake up for the 5PM News, nap from far it's workin' OK

So between sleep shifts I check the web for weather intel...I read the AFD's, scan the PWS's, watch the weatherman's standup on the TV News...Winter Storm Warnings have been issued for Noon Friday through 4PM Sunday! Today I even received an email newsletter on the forecast deluge. This one gave me pause. It's from The Storm King, Mark McLaughlin our local Tahoe Weather Historian.

Here's the takeaway that might keep me awake:

"Weather watchers like me have been somewhat expecting a potential flood
event this winter, especially in December. The influence of the strong La
Nina event
in the Pacific Ocean trends toward a weather pattern that can tap
a moist subtropical flow known in the West as the “Pineapple Express.”
Virtually all of California’s most destructive floods have occurred during
La Nina-influenced winters, so this approaching potent system should come as
no surprise. Another one is expected next week."

"This winter is off to a strong start; precipitation in October was 253
percent above normal and November dumped all that snow. The saturated soils will be unable to absorb much of the expected rain which increases the flood potential. Interestingly, this winter’s precipitation plot line is closely following the trajectory of 1982-1983, the wettest year on record. During the winter of 1983, nearly 90 inches of precipitation inundated the region,
including 56 feet of snow measured at Donner Pass."

So, maybe we'll be making history this season...O, how well I remember 82-83!

Weather Geeks and History Freaks couldn't do better than subscribing to Mark's Newsletter: Tahoe Nuggets. Mark's always a fascinating read, especially for those of us lucky enough to live in the Tahoe Sierra, with all this history under foot...and at times...falling from the sky.

More good times!
