Excited to share a new publication led by @drdavepeterson.bsky.social with contributions by Mike Fromm, René Servranckx and others, that analyzes the inventory of all known, worldwide, observed pyroCb events from 2013-2023! www.nature.com/articles/s41...

We must have a decently strong inversion tonight because whoever came all the way here from Oakland was rather loud!

Good move by UCLA. Not waiting around to see if the situation would improve. Sad because Foster was a UCLA guy but hopefully we can turn the ship around.

10° temperature gradient in less than 20 mi between Rantoul and Savoy. Can really tell who had a brush with the earlier storms and who didn't #ILwx Note these obs were taken ~20 mins apart but still a strong temp gradient within the county!

Top 10 Illini!!!

Greetings from the CliMAS Fall 2025 Welcome BBQ!

I maintain my SEC is overrated argument

Heck yes Lee Corso's last pick is THE

Very impressive #pyroCb/#pyrocumulonimbus plume from the Dollar Lake Fire this afternoon in Wyoming! It's currently stretching nearly the entire length of the state with activity still ongoing near the fire. #WYwx

Found the prettiest blue jay feather today! But left it for others to enjoy and because collecting blue jay feathers is apparently illegal!

🚨 @nws.noaa.gov #hiring continues! 🚨 A total of 26 open #Hydrologist positions (1315 series) across multiple locations have now opened and are accepting #applications, ranging from GS-7 to GS-15 levels. Check out the link for details: www.usajobs.gov/Search/Resul... ⏳ Applications due 9/2!

So the Savannah Bananas brought out Paul Konerko tonight, and as a life long Sox fan (who only wears Paulie jerseys at games now), absolutely lost it in the stands. Never thought I'd see Paulie bat again 🥺

Gorgeous, stormy day in Chicago #ILwx

I'm really an OT person because I just referred to 6.25 km as the "low levels" on slide 😅

Just spent an 3 hours "doing laundry" which included: a leaking, brand new machine that was supposedly fixed, a maintenance visit, the drum refusing to drain or cycle, bailing the drum with a plastic container, hand washing and wringing the clothes 😭

TIL that double headed sunflowers are somewhat rare but it was so cool to see this and go to the sunflower maze! FT some distance storms tnat also gave us a nice light show

There is a new world record for the longest lightning flash - 515 miles! The World Meteorological Organization has certified a lightning flash that extended from near Dallas, TX, to near Kansas City, MO, on October 22, 2017, as the new longest lightning flash. ⚡🧪🧵 (1/3) wmo.int/media/news/w...

Growing up an Ohio State fan, I was SHOOK to learn that Jim Tressel is the Lt. Gov of Ohio right now. Genuinely shocked at this information.

NWS is hiring! The first of several top-priority, mission-critical positions posted Friday on USAJobs.gov! Others will follow soon. Visit USAJobs.gov and search “NWS” to learn more.

Please bring us some relief, friend. It's too heckin humid.

I think I've hit the apex of my NYT crossword career. First Saturday solve with zero help and done in 10:17!

Atmospheric optics remains unbeaten

Send cool thoughts... and a nice, cold, dry, Canadian air mass please. AFD from NWS Lincoln

Small portion of the sounding @climasuiuc.bsky.social helped launched for the SESE Geosciences for Kids Camp earlier today. Very humid, tropical air mass setting the stage for heat impacts later this week. #ILwx

I enjoy vistors of all kind to the office but maybe not this guy. He's a bit creepy! Also, does anyone know what kind of bug this is?

🌩️🔝🧐

While it may not look very robust, the #pyroCb near the UT/CO produced an EF-2 tornado on Saturday. The 00Z sounding from Grand Junction, CO shows a classic inverted-v pyroCb sounding with some instability beyond any fire-induced modification.

you've heard about the college kids who can't do anything without ChatGPT's help—but what about the students who oppose generative A.I. for myriad reasons and refuse to rely on it as a shortcut? well, I found and spoke with a few of them here: slate.com/life/2025/07...

Are you normal or do you spend what was supposed to be a Friday night off creating a color-coded column in a spreadsheet?

Every place should make iced coffee with coffee ice cubes. Basically a second drink

From ~2 hours ago 2ENE Ashkum, IL. Didn't produce but was spinning for a while!

Just Idaho/AMS conference things

Berman: overshooting top area is most closely related to environmental shear (via updraft core area), while overshooting top depth is mostly determined by upper troposphere/lower stratosphere static stability #AMS21Meso

Grateful for the opportunity to share my work! (And maybe one day, I'll be tall enough for you to fully see me over a podium 😂)

Excited to be in Boise for #AMS21Meso! If you're here on Wednesday AM, come stop by my talk to hear what we've been up to with OTs!

I just... wow. #NDwx

I don't know who may need this but running "%history -g -f filename" gives you every line in a python install you've ever run.

Going to see the Savannah Bananas!!!!

It's 86/71 at KCMI right now. Happy first day of Climatological Swamp-aign (swamp Champaign)!

Summer fruit-centric baking remains undefeated

JERRY SOLD THE TEAM!!

Last radiosonde launch of CROCUS (~45 mins ago) 🫡

Roughly eyeball of the GOES IR temperatures for this #pyroCb are in the -47 to -50C range. Combined with the 00Z sounding from The Pas indicates that this pyroCb may have injected smoke into the stratosphere! This sounding is also the inverted-v common for pyroCb. weather.uwyo.edu/upperair/ima...

GOES-18 is currently providing a nice look at the large #pyroCb ongoing in Saskatchewan. The smoke that's been ingested into to the pyroCb looks visually different from both the surrounding convection (less white, more gray) and from the low level smoke from the fire (less brown, more gray). #SKwx

Might be done with classes but that doesn't mean the stress dreams about failing exams ends 😂

Robust plumes of pyrocumulonimbus billow from wildfires in Alberta. These were among many wildfires exhibiting extreme behavior yesterday across Canada.

First contour maps all the way back from my advanced dynamics/synoptic class in undergrad!
