Fully occluded mesocyclone/couplet in the high desert of Nevada! May have just had a tornado in remote Elko county. As a former high desert dweller these events still fascinate me…

Akron, from the other side at probably the exact same time.

“Signs point to yes!”

Incredibly shallow, post-frontal upslope easterly flow has funneled smoke from the Nebraska wildfires into Fort Collins this morning. Some of the highest PM2.5 concentrations in the world ATTM due to a lack of vertical dispersion - the cold frontal inversion is less than 1kft thick!

This flag speaks for us all

90 mph wind gust at the Cheyenne Wyoming ASOS (78kts) just set the all-time wind speed record at KCYS! #wywx #wind

85 mph gust at CYS ASOS just now!

71 knots at CYS ASOS currently!!!

Not until June 🌩️

Wyoming “cinema” on the way to work this morning…70-80mph surface synoptic winds causing havoc on I-25.
Half a dozen flipped trucks and ‘dirt excavation’ in unplowed ranchland. Could see gap/downslope winds top out 90-100mph today! #wywx

Full panorama of the 2025 Dickens/Wellfleet LP tornado+supercell!

View is looking ESE up into the mesocyclone. The RFD clear slot is visible in the upper right, and in the distance on the bottom left you can even see a bit of the FFCB. Stationary supercell with deviant westerly tornado. Perfection!

Greetings from Africa! This is Kevin. Everyone say hello to Kevin! This is one of only ~1,000 remaining Mountain Gorillas left in the world. We were lucky enough to spend some time with this amazing gorilla family in Volcanoes National Park in Rwanda.

First light after the storm on the stunning Cuernos del Paine mountains - Chilean #Patagonia, 2025.
A powerful late-spring blizzard dropped several meters of snow on the southern Andes during during the first days of our trip. Once the skies finally broke, the views were incredible!

So close and yet so far…just a bit west of a big-time South American dryline severe weather day. Looks like some supercells in there too. Would love to experience one of these in the future, but not on this trip!

Clouds do be moving fast

Chugwater, Wyoming around 9:30pm 11/12. Not as vivid as last night but a nice green glow and some diffuse red pillars! #aurora #wywx #northernlights

Brought the big camera to work for the Aurora show this evening. A WSR-88D radar makes for an interesting urban foreground! #wywx #aurora

Rather epic scene outside of NWS Cheyenne right now…covering an evening shift and got some nice photos around the office! #Wyoming #wywx #aurora #northernlights

10 meter resolution imagery of wave gradients in the eye of Melissa

Incredible Sentinal-2 satellite imagery of #Melissa at peak intensity before landfall. In the cloud-free areas of the eye you can see the physical effect of the surface wind gradient (2nd image): chaotic whitecapped waves near center transition to extreme sea spray/linear streaking near the eyewall!

#Comet #Lemmon last weekend, with both the ion and dust tails visible. The ion tail (thin one) was shocked by a solar storm the day before, resulting in a fractured look.
30x20s exposures at 600mm. Star trails in the b-round due to the comet itself moving over the ~10m of imaging. #astro

A year ago tonight over the Medicine Bow mountains in Wyoming! This was the same G5 geomagnetic storm that gave many folks along the east coast urban corridor their first view of aurora. Enjoy! ✨

A wild gradient of color angled across this scene made for one of the more unique fall photos I've shot. Taken last year on an adventure into some lesser-known wilderness in Colorado. #cowx #fall #peepin

Earlier this summer, an opportunity presented itself to climb the Montana state highpoint: Granite Peak in the Beartooth Range. This was my last of the Lower 48 "Big 3". A brutal 2-day push to bag the peak, what a beautiful reward to get to exist in some of the more remote wilderness in the US!#MTwx

Thank you!

Dreaming of Wellfleet/Dickens...the perfect tornado. 👌

🚨It's happening people! THIS IS NOT A DRILL! 🚨

Spotted yesterday 8/28 in southeast Wyoming. Summer is OVER! 💪❄️

The classic Rainier + Tacoma Harbor shot. From 2022.

Rainier, Adams, Hood and Jefferson from the north in monochrome.
Taken on approach to SEA on our climbing trip. #WAwx #Rainier

While waiting for a weather window to summit Rainier, we saw several epic lenticular/cap clouds over the summit throughout the week. This telephoto view was particularly wild - a combo of stratified lenticular clouds over the summit & convective surface clouds underneath. #wawx #Rainier
