Hello, Mastodon followers! After a hiatus, I am going to be reverting to my older (original) Mastodon account ( mastodon.social/@weatherwest ). I am still working hard to find a solution to the considerable challenges and time commitments surrounding posting to 5+ separate social media accounts manually, but I may have found at least a partial solution (via Fedica) that should prevent the "garbled and truncated" post issue I previously could not resolve via IFTTT. Let's see how this goes!

Let's try that again! Next YouTube live session Tue Mar 19 @ 2pm PT. This will mainly be an open-ended "ask me anything" session, though I'll also briefly discuss upcoming shift to wetter/cooler pattern again in California. #CAwx #CAwater https://t.co/LH57KiIEgO

First half of 2024 will likely be "more anomalously warm" than second half of year with expected imminent demise of #ElNino

After a brief hiatus due to travel, the live sessions return this Thu 3/14 @ 2pm PT! This will be an AMA ("ask me anything") style session, so come ready with your questions and submit them via live chat. #CAwx #CAwater #CAclimate https://t.co/3gQApa0ypT

Still important to note that the broader context of this is that Earth still hasn't reached the oft-discussed but frequently misunderstood multi-year sustained 1.5C warming level...yet. But even given that context, these recent numbers are remarkable

As noted earlier, present storm is another unusually electrically active one by CA standards. An impressive continuous line of organized t-storms is moving onshore along the North Coast; "thundersnow" possible throughout storm in mtns, with lightning/small hail elsewhere. #CAwx https://t.co/H1bmo1Kmbd

I'll be live on YouTube at 10am PT discussing the inbound storm that will bring extremely heavy Sierra snowfall, disruptively heavy snow to low-ish elevations in NW CA, and cold/soggy weather elsewhere with some thunderstorms (yes, more of them!). #CAwx #CAwater https://t.co/pBirv1EWYO

New Weather West post on cold storm sequence headed for California, including the high likelihood of extremely heavy Sierra Nevada snowfall/blizzard conditions (I strongly advise not even attempting to travel in mountains after noon Thu!). #CAwx #CAwater https://t.co/1vxiLnAkU4

It's plausible that parts of the Sierra west slope and crest could see one of their top 5 snowiest 1-2 day periods on record with inbound Fri-Sat storm. That's pretty extraordinary given the very slow start to snow season in many spots. Quite some whiplash! #CAwx #CAsnow https://t.co/cavqRxCj5J

There is a chance that some places on Sierra western slope and along crest could see a top 5 snowiest day/2 day period on record with the inbound storm this weekend! Truly extraordinary given the very slow start to snow season in many areas. Quite some whiplash... #CAwx #CAwater https://t.co/ZeyKHDtJoP

Update: I'll have a new blog post this afternoon focused primarily on the extremely heavy Sierra snowfall expected Fri-Sat. I'll also have the below live YouTube office hour (10am PT Thu) to discuss further, along with other assorted topics of the week. #CAwx #CAwater https://t.co/pBirv1EWYO

Blizzard Warnings are rare in the Sierra Nevada despite the regular occurrence of major winter storms, so this signals high confidence from @NWSSacramento and @NWSReno that the Fri-Sat event will feature both extremely heavy mountain snowfall and strong winds. #CAwx #NVwx https://t.co/zT0Jnzy4kO

This is going to be a "big deal" snowstorm for the Sierra, especially considering the slow start to snow season (snow whiplash?)! Join me live on YouTube Thu AM for discussion; I'll also have a new blog post Wed or Thu. #CAwx https://t.co/pBirv1EWYO

There could be some flood risk in parts of NorCal, depending on how things evolve, but overall the next storm cycle appears to be one more likely to be net beneficial than harmful (it will be somewhat less intense than the last two, colder, and centered north of last one).

weatherwest, 3 months ago to random

....That's good news because it means that the heaviest precip will likely skip waterlogged and plagued SoCal, and focus on some of the areas that have seen relatively less precip this season. Also, this may help fill in some remaining gaps in Sierra snowpack. #CAwx #CAwater

After some additional warmer and drier days, a more active weather pattern will return to CA next week. This one appears more focused on NorCal vs. (SoCal), and will likely be somewhat colder--yielding better Sierra snow accumulations. That's good news because... #CAwx https://t.co/ANV5A9gv6Z

Due to popular demand, I'll have a brief "pop up" live YouTube session shortly (2:10pm PT!) to discuss ongoing convective heavy rain event in SF Bay Area, flash flood risk from this and ongoing precip in SoCal. #CAwx https://t.co/2gh8E3k2bI

This line contains a broad and slow-moving area of heavy rain, with embedded torrential downpours. In additional to lightning, it may also generate some locally significant urban/small stream flooding in the SF Bay Area this PM as it very slowly progresses eastward. #CAWx https://t.co/vQJP5V48oE https://t.co/Cb2we1Ncgq

A pretty impressive and slow-moving line of thunderstorms (containing lightning, torrential downpours, and maybe some small hail) is now moving across the SF Bay Area. Pretty good rotational signatures offshore supportive of (multiple?) potential waterspouts offshore. #CAwx https://t.co/2Jk4Uy0GUK

weatherwest, 3 months ago to random

Update: I'll likely be starting this live session EARLIER than estimated, right around 1pm PT (vs 2pm PT). Severe thunderstorms have developed near Fresno and further activity is likely to the north over the next few hours. #CAwx https://t.co/jDu0oGBjCi

Update: the ISP has committed to no additional unannounced downtime today, so should be good to go with livestream(s) later this PM.
