Denali: The roof of North America at 20,310’! It is said you don’t just climb Denali, you endure it. After a 3-week odyssey in one of the most inhospitable places on earth, I can think of no more accurate description. Climbing the West Buttress route & finishing under the midnight sun-unforgettable!

Harvested some whopper hailstones and saw a nice occlusion in far eastern CO/KS today, despite sky high LCLs. Saw the suspect dust swirl as well…a bit more moisture and GLD would have been in trouble! #COwx #kswx

Classic May day in southeast Wyoming….skied a few laps off Medicine Bow Peak, and bonus storm structure after! #wywx

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.

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!

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

71 knots at CYS ASOS currently!!!

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! #Chile #sunrise

The legendary Fitz Roy at sunrise above Cascada Escondida. Patagonia at its finest! El Chaltean, Argentina 2025. #patagonia #fitzroy #photography #sunrise #waterfall

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!

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

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! ✨ #solarstorm #aurora #auroraborealis #WYwx

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

Dreaming of Wellfleet/Dickens...the perfect tornado. 👌 6/16/25 #NEwx #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. #wawx #sunset #Rainier

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

Mount Rainier- State highpoint #40! The theme of this trip was resilience. A self-guided climb was certainly an added challenge and really forced competence with crevasse rescue skills and route finding. Got the weather window we needed & gutted out 9,200’ to what I’d consider my hardest summit yet!

Still riding the high of this tornado chase a few weeks later. Here is a slightly more cleaned-up edit of the best tornado + rainbow + RFD storm structure I'll probably ever see. Enjoy! Dickens/Whitman, NE 6/16/25

This was a particularly fascinating photo of the Dickens tornado. The bottom 1/3 of the condensed tornado appeared to 'hollow out' leaving just the shell of the circulation condensed, surrounded by dust. If you look closely the residual condensation takes on a 'braided' look similar to vinyl tubing.

The perfect tornado. 16mm full wide. Dickens, Nebraska. 6/16/25

Yesterday’s Panhandle supercell in OK remained just-so-slightly elevated fighting stable air behind the morning OFB. Viewed from the NE the base had a laminar appearance despite robust convection aloft. Views inside the RFD show the effects of stable air as various occlusions tried & failed to wrap!

Single shot 70mm from yesterday. Ghostly. Etherial. And a photo I'll probably never be able to top! Dickens, Nebraska. 6/16/25

Absolute insanity Dickens Nebraska tornado a bit ago at close range! Right off the iPhone lens spots and all!

Career tornado intercept just now Dickens Nebraska!

Another nice evening of supercells in the big field 👌 #COwx

Textbook occluded supercell north of Anton Colorado today. Could not discern any ground circ/tor in there but about as good a look as you’ll get. #cowx

Earth will warm 1.5 degrees Celsius above preindustrial levels in just two years, new data shows. Irreversible tipping points — like the melting of Arctic ice sheets or the collapse of coral reefs — are closer at hand than previously believed.

Wildflowers are peaking on the trails around Fort Collins right now! Ideal flower chasing season with several damp and cool stretches through May/June. 🌸🌻🌺 Got chased off Author’s Rock by storm #2 of the day…

Cheyenne mini supercell today passing over the office #wywx

Just had to go to work to see this guy yesterday ☁️

I believe I saw a tornado, or at least a very low fc, yesterday out of this storm north of Strasburg/Bennet Colorado. Photos time-matched to radar. Was sitting on the Denver Cyclone wind shift boundary ~15mi south distracted with another storm when I finally noticed what was going on up there. #cowx

TOTY 🏆

Closer view of the Elbert CO tornado/funnel yesterday. It was down a bit farther before I got the 200mm on it. #COwx

Wide view of today’s tornado/very low funnel, fully occluded just west of Elbert Colorado. 🌪️ With such wet and lush ground, lofted dust would have been very unlikely underneath this and I am pretty convinced it was down… #tornado #supercell

Somewhere over the rainbow? Yesterday near Akron, Colorado! 🌪🌈 #cowx #tornado

Tornado north of Akron Colorado about 5 min ago. Viewed from directly behind the occlusion looking east. Blew a tire and got behind but got a view!

The Kanorado supercell with a nub funnel under it today. Great structure here but chaotic CI and storm mergers played havoc for the setup in far northwest Kansas today.

Outstanding radar loop from TDEN. You can see the surface vorticity circulations literally in clear air along the DCVZ boundary before they even get ingested by the supercell. In this case the supercell has tornadoes under the mesocyclone but they are certainly strongly aided by ground-up process!

A fantastic and highly photogenic chase yesterday near North Platte, Nebraska with multiple landspout tornadoes and a top-tier shelf cloud. I love the rays of light and muted color behind the funnels, just wish we could have gotten even closer. The shelf was a spectacular finale too! #NEwx #tornado
