As to those “others [that] are being explored” — HRRRCast v2 is just about ready to go, with more variables and levels in the training (and thus the output), to be followed quickly by v3, a true 3-km AI model. More soon!
The @nws.noaa.gov ventures into AI weather models, with data now available for those who wish to utilize and/or assess. Others are being explored (h/t @clarkevanswx.bsky.social) as well!

Special thanks to Jeremy, Chris and Landon for their expertise/ knowledge.
With the help of some friends photos, I made quick guide to the structures most often seen during mid latitude aurora events to communicate to general audiences what they’re seeing!

My family got cable when I was about 6 years old. I couldn't stop watching The Weather Channel and realized that I loved weather and wanted to be a meteorologist. Several years into graduate school, I was a Dynamics I TA and ran the labs and realized that I wanted to teach meteorology.

( #NWSNewOrleans): We’re in the home stretch of the 2025 Atlantic #Hurricane Season. The latest summary map shows a mix of long-track systems most of which RECURVED out in the open Atlantic.
A busy year for the western Atlantic, but thankfully no real threats to the Gulf region.

With lots of sun in central Illinois and high temperatures in the 50s, this weekend is a great opportunity to finish fall yard work and put up outdoor Christmas decorations (I've already done both).

The flash flooding threat has increased this afternoon across South-Central Texas, including the city of Del Rio and the Edwards Plateau region. A couple of rounds of rainfall with high rates makes it possible that 3-5 inches of rain could fall with some locally heavier amounts certainly possible.
