Yet another cut-off low this week in CA, w/unsettled late May conditions (& also, a temporary reprieve re: the NorCal, but not SoCal, marine heatwave). But warmer weather associated w/PacNW ridging looks likely in June. Plus: a bunch of new YouTube links!

Elevated fire weather conditions continue through Thursday. Afternoons will be the time frame of most concern when relative humidity is lowest and winds are strongest with gusts up to 30 mph across ridgelines and through gaps and passes.

I know there's tremendous interest right now surrounding growing potential for a strong El Niño event, or even a so-called "super" El Niño. In this just-recorded live session, I break down the current forecast, its implications, and associated caveats. www.youtube.com/live/rZvJPlP...

A fun Central Valley geology read for all the rockheads.

Looking ahead to mid-May, there is now pretty strong inter-ensemble agreement regarding the development of a much more pronounced Western ridge once again, with the potential for a significant heatwave at that time. This would mark a major pattern shift, so stay tuned!

Rain starting to return to the Bay Area this morning, should see increasing wind and rain into the PM/evening with thunderstorms possible Tuesday. 4/20/2026

Still expecting an unusually strong cold frontal passage (by NorCal April standards) later this PM. Expect a period of intense rainfall & embedded thunderstorms with gusty wind at lower elevs (locally severe near SF Bay), plus a burst of heavy & accumulating Sierra snowfall. #CAwx

🌡️Every single weather station we have recorded the warmest March on record. Most would have been the warmest April too. More sites below🧵 https://x.com/NWSBayArea/status/2039348328870129861

Maybe you heard somewhere that the COVID-19 pandemic started with a lab leak? NO! That is NOT what the evidence shows. It was not a goddamn lab leak. I’ve had enough. Here is what the evidence shows: it was zoonotic spillover at the market rasmussenretorts.substack.com/p/five-reaso...

Okay, so: 1) fertilizers are in shortage; 2) E15 comes from corn fed with fertilizers; 3) land used to grow corn for ethanol produces 3.2% of the energy generated by covering the same amount of land with solar panels. With all respect, what are we doing here?

Gardening friends: are these some kind of tuber? I found them in a hanging basket where I had previously planted either a zinnia or a dahlia, I forget which. The space looked empty, so as I was putting another plant in it, I dig up these. What do I do with them? Just replant them somewhere else?

A dominant, persistent, and record-breaking heat dome. This satellite animation shows the evolution of the ridge over the last 6 days.

The seasonal anomalousness, as well sheer spatial extent, of upcoming record-shattering Western U.S. heatwave is genuinely startling. This will be associated with, by far, the strongest ridge ever observed during (at least) any Nov-Mar month. #CAwx #AZwx #NMwx #NVwx #UTwx #COwx

I knew municipal utilities generally provide lower electricity prices than investor-owned monopoly utilities, but I had no idea the difference was *this stark* in California. No wonder CA electeds are pushing to make municipalization easier and cheaper. energyathaas.wordpress.com/2026/03/09/t...

CW3E AR Update: Confidence has increased in a long duration #AtmosphericRiver event associated with a slow-moving low-pressure system, forecast to bring heavy precip to the U.S. West Coast between Sat 21 and Wed 25 Feb. See our latest outlook for more information: cw3e.ucsd.edu/cw3e-ar-upda...

The storm is coming, now is the time to prepare. Conditions will deteriorate through the day Sunday. https://x.com/NWSBayArea/status/2022835634235162633

☔️A pattern change occurs this weekend! From Sunday onward, wet conditions are forecast. The forecast is for nearly daily, but intermittent periods of rainfall. Rainfall totals could average 2” to 4” with isolated spots up to 6.” https://x.com/NWSBayArea/status/2022114456457949580

More than half of dogs trained to help people with blindness, PTSD, autism, and other conditions fail to graduate. New scientific approaches could help, getting more--and better--working dogs into the hands of people who need them most. My new feature for @science.org!

For those familiar w/ "ARkStorm/ARk2.0" flood scenarios for California, a comparable event has been unfolding on the Iberian Peninsula. These ridiculous rainfall accumulations, caused by a long series of extremely moist atmospheric rivers, have brought widespread severe flooding to Spain & Portugal.

New Weather West post out now: “Warm West/Cool East” dipole to develop over North America in late January; mostly dry/warm conditions lead to record-low Western U.S. snowpack. I'll be discussing the content therein during Wednesday's livestream. #CAwx

So I will just throw this out there. If ICE employees are basically exempt from being sued, or any legal recourse for their actions, If a bunch of us joined ICE, could we beat the crap out of other ICE employees with no risk of discipline? @joycewhitevance.bsky.social

This piece also includes a perspective from me, on the "return of the urban firestorm," originally drawn from a conversation I had with David in the immediate aftermath of (yet another) recent wildfire disaster--the Dec 2021 Marshall Fire in Colorado.

I am impeaching Secretary Kristi Noem, who is an incompetent leader and a disgrace to our democracy. She wreaked havoc in the Chicagoland area and has brought her reign of terror to Minneapolis. One of her rogue ICE agents shot and killed an innocent woman today. It must come to an end.

Congressional Republicans have surrendered their power to the president they are constitutionally obligated to oversee. It is a startling abdication, rivaled only by the Trump’s lies to voters about what his foreign policy would be once he took office. Compare Candidate Trump to President Trump ⬇️

9:40 am. Moderate to heavy rain moving into the Bay Area, with more offshore ahead of a developing area of low pressure (i.e., cyclogenesis). It's a rainy day and Monday. 1/5/2026

Zelensky: Another year passes, earned by the dedication, resilience, and daily work of Ukrainians. This year was made possible by our defenders, who stood not just for Ukraine but for all who value freedom and dignity. We move forward with memory, hope, unity, and humanity. Happy New Year, Ukraine!

Happy holidays all!

The localized but very serious flash flood event ongoing in/near Redding, CA may escalate yet further, with a narrow line of torrential downpours along persistent convergence line re-developing yet again over same area. Widespread inundation & swift water rescues ongoing. #CAwx

Per NY Times’s Michael Grynbaum on X, this is Sharyn Alfonsi’s email to her “60 Minutes” colleagues in full:

New Weather West post out now: A wet and stormy week ahead in California, with substantial SoCal flood risk and initially warm Sierra rain transitioning to very heavy snow. Plus, join me tomorrow (Mon Dec 22) for a live discussion (link therein!). #CAwx

7-day total QPF from last night's 00Z model runs. IMHO the biggest takeaway should be the huge range of solutions and not to cherry-pick the biggest to characterize and hype this series of storms.

Update: very active weather week to come in CA! First, a persistent and very warm atmospheric river will remain draped over NorCal, continuing to generate rain--and snow levels in the Sierra will rise yet further, above 8k-9k feet. SoCal stays warm/dry through Tue. [Thread] #CAwx
