Javier, our new CEO, wanted to thank everyone for a fun and motivating first week. You all have made his transition process enjoyable. He has much to do but insisted on relaying that his initial numbers indicate that the dogs are all very good and will likely continue to be ❤️

It appears we’ve been gifted a new tree ornament this evening #CatsOfBluesky

Some scenes of Boulder this morning.

The NWS zone forecasts in the Colorado high country are finally starting to look how they should look.

Here is a godawful joke in chart form to ruin your Christmas season 🤪🎄

Today Apulia has never been this Great Plains-esque. Insane supercell and tornado in the Manduria area (we're working on the damage... frustrating is quite reductive). Videos by Fausto Perretti and Giuseppe Mauro (below)

Inbound afternoon traffic.

A couple of scenes from my hybrid road/trail run this morning near Golden Gate State Park. It was so nice to have some fresh snow, even if the totals were underwhelming.

caught a nice dust devil on the stream

Probably one of my tor favorite photos (that I captured) from this last storm season. It was in the earlier stages of the Arnett, OK tornado of May 18. Of course, it's hard to compete with Dickens, NE or Gary, SD, but I wasn't on either of those two events. With @francescodemartin.bsky.social

Tehran is having an historic drought due to a combination of factors, including climate change. The ocean is not helping. 1/3

Every Category 4 and 5 Atlantic hurricane since 2020, all together, in one group photo. H/t to @ferragamowx.bsky.social for the inspiration.

Ever feel like your town gets more nighttime tornadoes than others? Here's a map of tornadoes by time of day (nighttime tors are plotted on top of daytime tors to stand out). I feel for you Tulsa, Jackson, Birmingham, Nashville...

A view from the neighborhood this morning.

“The prohibited activities would include joint research, co-authorship on papers, and advising a foreign graduate student or postdoctoral fellow. The language is retroactive, meaning any interactions during the previous 5 years could make a scientist ineligible for future federal funding.”

A day that will never be forgotten by those in the presence of these storms, 4/26/24.

Sunrise in 16 seconds. I sort of regret not doing the sculpted wave cloud to the west instead. Also, sorry for the small jump in the middle.

Despite being sick with COVID (again) I couldn't miss this magical evening with my old friend, Lady Aurora

My first attempt at research in fires and air quality was just published in JGR-Atmos. It reviews the performance of NOAA's UFS-AQM model during the terrible 2020 wildfire season in the US and preludes a forthcoming paper on a novel UFS-AQM ensemble prediction system. doi.org/10.1029/2025...

I don't know if I've ever seen the snow at high elevation this pitiful by Nov 8 in my 15 years living in CO. Here are views of an almost snow-free Sawtooth between Bierstadt and Blue Sky and a slightly more snowy (a fresh dusting that will be gone in a day or two) Square Top Mountain this morning.

Halloween’s spookiest two-headed beast. #Catsofbluesky

Any of the Front Range folks know what this fire is all about in Boulder behind Green Mountain? It is not on Watch Duty.

After a devastating landfall in Jamaica, Major Hurricane #Melissa has emerged north of the island. In a few hours it will strike again, this time in southern Cuba.

This has probably already been posted here, but Melissa has displayed a classic mesovortex pattern that can be modeled in the simplest 2D atmospheric models ("nondivergent barotropic models"). Here's a comparison of this morning's VIS sat and Kossin and Schubert (2001) experiments.

Surprise horseshoe vortex from the NCAR parking lot this morning!

It must be so fun to play with Aaron Rodgers. If you don't make literally every catch on every ball he throws to you no matter how inaccurate he puts his hands on his hips and curses at you like an alcoholic gym teacher and then after the game you have to hear about how 5G causes IBS

Northern Colorado is looking pretty even if we are cruelly being denied seasonal snow.

#Melissa is intensifying very rapidly this evening. TDR structure is nearly perfect for a TC of this intensity. Incredibly symmetric, strong eyewall, and a deep, aligned circulation. The sky is the limit. Very scary situation.

NPR ran a story last night about NSF terminating funding for AI focused meteorology research & the (IMO) insane explanation they got from OMB. I shared my perspective on this and our continued insistence to shoot ourselves in the foot when it comes to scientific R&D. tinyurl.com/2kzujwz8

I was having major FOMO, but lo and behold, a sizable No Kings event materialized in my hodunk town of Erie. I’ve never seen any political gathering like this in my quiet town before today.

Five years ago today, punishing and relentless winds thrashed the continental divide and foothills. In mere hours, a fire of unknown cause ignited near Jamestown, CO and quickly escalated into a conflagration consuming vast swaths of forests in vaporizing heat and flames. Here was the scene in Erie.

A comfy blanket of below Green Mountain this morning.

All meteorologists can relate.

Aspen season is the best season.

I’m not a big fan of the damage they do to our yard, and therefore often cheer on owls to have good meals (for the sake of a healthy ecosystem of course), but they are cute. Here’s a baby one found just now.

The Advanced Study Program’s Graduate Visitor Program Fellowship is accepting applications! This fellowship allows graduate students to work on their thesis, dissertation, or final project equivalent, with guidance from NSF NCAR scientists and engineers.

Fall weather has arrived and this rainbow fills my current field of view (when not typing this into my phone). As grim as national politics are, I take solace in the beauty offered each day by our surrounding universe.

As seen in SE South Dakota 19 years ago today.

Ahhhhh tornado continues on the ground just north of the 4-corners! It would incredible to see this out in that amazing terrain! This is from the Navajo Police Department FB page.
