I remember running a local large-eddy simulation on my desktop in grad school and being okay with it taking 7 days to run. Now, I am grumpy when I have to wait for more than an hour on my laptop.

An NWS AI generated graphic with crazy placenames has went viral, potentially jeopardizing trust in the NWS and in extremely promising AI meteorological applications. We need to be clear about the various AI technologies in question - and be cautious of generating "AI slop." tinyurl.com/3ds83yn2
Will "AI Slop" derail a potential revolution in weather forecasting?
NWS issues with AI generated graphics raises concerns. In weather, record warmth feeds risks of severe weather and flash flooding.

I worry the framing of the first phrase is leading people to misattribute the errors described in the second. Yes, there is a push to incorporate ML/AI techniques to augment and/or complement prediction models. But the map was seemingly just a poor attempt by an LLM/whatevs to display existing data.
Amid a big agency push to use AI models in weather prediction, the National Weather Service shared a forecast map riddled with spelling mistakes, non-existent locations and other geographical errors.

Norman pals: the city is hosting a resource fair and warrant clearing event next Wed, January 14, at The Well from 1-4 pm.
Folks are able to clear certain municipal warrants in a safe setting.There will be materials to mend clothing, stylists to help those needing a trim, and more.

Don’t let resolution grinches get you down. The start of a year is a great time to set a goal for yourself. So set your goal and do the work and be proud that you want to be better at something.

This was very fun to work on, emerging from student class projects a few years ago. How sharp can a cold front get? We were able to point to some answers.
It hasn't been cold this December, but 3 years ago it got cold in a hurry. Do you remember the cold front on December 21, 2022? It was extreme in all kinds of ways, which you can read about in this blog post.
Among the highlights: the temperature dropped almost 25°F in ten seconds in Akron! #cowx

One of my favorite activities the past three years has been serving on the high-performance computing allocations panel for the Computational and Information Systems Laboratory at NCAR. I’m always amazed by the breadth and depth of the computational atmospheric research supported by NCAR.

For no reason at all, here is near-surface potential temperature from a paper in 2016 where we looked at ways to evaluate the temperature structure parameter: one without mean wind and one with a 6 m/s wind. Grids are 2016x2016x1008 with 4-m spacing in the horizontal and 2-m spacing in the vertical.

One of my neighbors has been putting up these fish facts posters. All kinds of different fish, marine, freshwater, deep, shallow, all kinds. This is a good one. “Stg this real fish” took me out. Good work, neighbor.

for no reason, here is an animation from a direct numerical simulation of a share-free atmospheric boundary layer. this is vertical velocity, with narrow bright areas being upward motion, and broad dark areas being downward motion. this is near-surface in the x-y plane (you're superman looking down)
