Here's the Arnette, OK supercell/tornado time lapse from May 18. I haven't gotten a full tornado time lapse in quite some time, like ever.

I'm sure glad the radars are still running so we can see what a hailer can do to splatter the S-band radiation in all sorts of directions, whether from side lobes or the main beam. Earth is going to get close to this.#txwx

The thing about tools like cli-MATE and ACIS is not that the data won't exist (not yet at least). It's that they make getting the information you want so...efficient.
Can I write some code to do the same task? Sure, but not everyone can, and why should we need to when a great tool already exists?

Some news. Those of you that utilize the cli-MATE tool from the Midwest Regional Climate Center will no longer have access unless funding is restored before the 17th.
A huge loss.

This lab makes it possible for the NWS to forecast severe weather at the level we do. They can do much more too. If lost there’s no going back to fix it.
HRRR? RRFS? Those models don’t exist without NOAA’s Global Systems Lab.
The physics used in even more models? Not possible without us.
Decision-support tools like DESI and IDSS Engine used throughout the NWS? Also us.
What my lab does is *integral* to weather prediction and keeping people safe.

After a super windy March, this is a nice change in #okwx. This was taken from a race hosted by the Lake Thunderbird Education Foundation. thunderbirdsailingclub.org

Third night in a row of a gravity wave flying through OK. This one’s enough to reverse a 40 mph north wind to a 60 mph south wind.

Here's an odd CC drop that looks like a distant debris signature SE of Van Wert, OH. It's along a shear zone but not associated with a significant reflectivity line. That's to the SW. But I can't rule out a tornado either.

Look upstairs and see some amazing supercell updraft signatures NW of Memphis.

This supercell east of Cheyenne went up with surface temps in the mid 40's F. The storm appeared to have little rain, a lot of ice, and a rather prominent peak. It's got high Zdrs (much higher than anything down low), very low CCs and high spectrum widths. I've got my own idea what it is.

Look at that string of updrafts (circled in the lower right).

Is this why the only rotating storm I see is the left mover passing over Chickasha? Knock off the lowest 700m of flow and it's all negative SRH.

Thunderstorm gravity waves are flying through the Northern Lower MI peninsula. That means high wind gusts even with low 30s F temps. Cool! See the paper by Borchardt and co-authors. doi.org/10.1175/WAF-...

I pulled up GR3 and the storm total rain was saturated at 5” over most of the Brownsville and Lowe Rio Grand area. It’s so extreme I thought it was an error. Nope.

A new cell fired up north of the older cluster west of Mt. St. Helens. But so far there are no low-level velocity perturbations (like azimuthal shear).

Regarding the PACNW severe, I'm just not seeing the CAPE anywhere near forecast. Current analysis has 500-1000 www.spc.noaa.gov/exper/mesoan...

A complete and all-out attack on NOAA. Without a functioning NOAA there is no function seafood industry, no functioning radar network, no functioning weather models (US or otherwise). Would you cut a personal investment that saved you 70 times over your original investment every single year? (1/3)

Together with recent firings and resignations, the new cuts could hamper the National Weather Service’s ability to produce lifesaving forecasts, scientists say.

In addition to the amazing work Kitty did in Nome before being fired, she has a side business selling stickers. Supporting her business is a small thing that could help out a lot. Note: definitely NSFW. www.sopowart.com/s/shop
The woman interviewed for the story (pictured here) was a co-worker of mine. It's hard to describe the sacrifice required to move out to rural Alaska. These people are deserving of our gratitude; instead, they were shoved, quite literally, out into the cold.

Apparently lake effect snow was quite active off of Lakes Eufaula and Texoma #okwx this morning and yesterday. Here are a couple images of previous snow tracks and current cloud plumes.

President Zelenskyy has been one of the greatest leaders of our time, guiding Ukraine through the darkest period of its recent history, rising up to Russia’s unwarranted aggression, being an inspiration to the Ukrainian people and ensuring that Ukraine’s voice is heard on the world stage.
