Former PV_Anomaly/Baroclinic Instability

I had the great pleasure of putting out Alaska’s first #heatadvisory

Happy to see we were highlighted up here. I just had a webinar with someone I am working with on a project and he stated his office (I won’t name it) is going to lose 4 to VERA which was just approved by DOC. They will have…gasp…two leads and two Mets. That’s it. With upcoming severe season.

Here's an animation of #GOESWest True Color RGB images -- it appears that the von Kármán vortex street was created by northerly winds interacting with the sharp western tip of Nelson Island? Full res: cimss.ssec.wisc.edu/satellite-bl... #AKwx

That looks to be the cause. What an amazing view!

A colleague @dustinsaltzman.bsky.social caught this today on satellite. The actual loop is incredible. May be worthy of a satellite post. #BeringSea #akwx

Absolutely good sir. Also, it still says hi, because it is still sitting there an hour later 😊

Very much reminiscent of April 14 2011. Dust swirling into the cyclone, fires burning over the plains feeding smoke into the center.

Someone’s Christmas lights, ha. It is North Pole, AK 😄

Moose just chilling in my yard, after eating several large branches.

I like moose, but not when they are eating my trees. #ak #fairbanks

Stunning satellite imagery this morning with the deep cyclone over the N Plains and secondary subtropical stream jet streak emerging across the Gulf states. 110 kt 500 jet streak crossing the warm sector near the Gulf coast is pretty wild. #highrisk

My favorite, the #SPC #basal shortwave trough. 110kt 500 hpa jet streak intersecting the southern Gulf states, projected by
All models on the #high risk day. #basal

Just tossing this out there. Day 8. Yea day 8. 192 hour verification for the trough ejecting into the plains today, by the #ECMWF AI model. Incredible.

I am still proud to say I experienced the worst snow season of all-time in 2014-15. I remember chinook after chinook, rainstorm after rainstorm. I learned about studded tires that I still utilize to this day, thanks to those meager years in the mid 2010s.

How r things in cali? Hope you r well man.

We used to call them, #convective bombs.

Also credit to the often mocked Canadian Regional. It’s nonhydroststic physics can come in handy sometimes.

Interestingly enough, the course res ECMWF ensemble did the “best”. At least showed the potential.

The HRRR doesn’t even have it right now 😂 Yeah I agree, these are the hardest events for models. Weak convergence coupled with local ocean driven instability, with lifting along a mesoscale front in PWS, and lifting by huge but highly complex terrain. It’s a model problem that isn’t going away.

Turnagain Arm convergence can pay dividends in bad snow years. Also, warmer ocean temps presumably can result in more convective banding. Reminds of the tough snow forecasts of the 2010s.

Your tabby has similar color patterns to mine.

I would also have to think that played a role in why Kaktovik just blew 50+ mph from the east over the last three days with hardly any blowing snow restrictions.
