Still can't believe this happened. Still can't believe this is a photo I took.

This weather with 0 wind chill is lowkey peak

@Tschlittphotos @Becca_Furnish The struggle is real!

[Jim Tang @wxmann]

Apparently there were some landspouts today in the Navajo Rez just south of Monument Valley. Environment certainly was favorable for cold-core magic (I was close to pulling the trigger on this)... not 100% sure of the veracity of this but would not be surprised if it was legit.

[Jim Tang @wxmann]

There were also funnel clouds reported near Shiprock. I'm confident about this one given multiple reports and look of radar near that time.

Three year anniversary of one of my most well-aged tweets of all time

It's always the ones you don't think about too much and just tweet out of vibes

It’s October 24th, 2023. A small storm named Otis has been upgraded to a Hurricane, but further strengthening is forecast to be limited.

He should pass to the W of Acapulco as a CAT 1 and make landfall tomorrow night. Doesn’t look like conditions in the city will be too severe.

@WestsideLAGuy People in NYC are happy?

@TheMindScourge Tell me you've never driven from Las Vegas to SLC without telling me

@AZStormChase @noahlt @grok is this true

For fuck’s sake

@PlaysSaheb I meant main archipelogo of Japan (the fine print of the chart says the analysis excludes the Ryukyu Islands)

[Jim Tang @wxmann]

FWIW, TC landfalls in Japan on/after the last week of October are exceedingly rare. Only 3 in a 70-year history, and the dropoff begins on Oct 1.

This time of year, the Asian NE monsoon typically strips TC's before they can get as far north/west as Japan.

That should've been the red flag re: the Deepmind solutions for Champi.

[Saheb Singh @PlaysSaheb]

Are GDMs Working Right? : On 18z Oct 19 as well it is clear GDM FNV3 accounted for Taiwan, whereas Physics-based models did not, note every single output differentiates farther West, this + West shift slowly is why synoptically and mesoscale GDMs demonstrated TC Env.

[Jim Tang @wxmann]

@GumryWX If temps went from 70 to 77 in three hours in late afternoon, that's some significant WAA going on, can't be ignored esp when 500mb is at -15.

[Jim Tang @wxmann]

@EarthUncutTV Main archipelago of Japan* (wanted to save characters on my tweet lol)

[Jim Tang @wxmann]

Anyway I called this out a few days ago before doing the statistical analysis. At the end of the day, it looks like a scenario between the dynamical and ML guidance ended up being the right call!

[Jim Tang @wxmann]

The track forecast for #Champi is fascinating. On one hand, it's hard to imagine this 500mb pattern without a recurvature, and Google Deepmind explicitly forecasts this.

On the other hand, if Champi wanders too close to Taiwan, rapid weakening from the surge of stable postfrontal northerlies and land interaction, and lee cyclone development in the Taiwan Strait will force the track west. This is kind of oddball dynamical situation I could see the physics-based guidance handling better than machine-learning guidance. Hard to bet against the GFS/ECMWF consensus <5 days out.

Whatever happens, it'll be a good test of physics vs. AI in a challenging forecast situation!
