Take a two-day glimpse into the dynamic atmosphere above the Eastern Pacific Ocean.

A bitterly cold second half to the month of January saw an extensive growth of ice over the Great Lakes, with over half of the surface area across the five lakes covered in ice. Lake Erie, the shallowest of the Great Lakes, has over 95% of its surface area covered in ice.

For 40+ years, Storm Peak Lab in Colorado has allowed scientists to have their “head in the clouds" to explore atmospheric chemistry and processes like mixed-phase cloud microphysics. Learn more about this high-altitude research station on AMS Headlines: https://bit.ly/3OdCql2

Newly published statistical analysis from our researchers begins to outline an approach to better deal with this uncertainty, known as spatial variability, in storms and the vast swaths of air around them. engr.source.colostate.edu/findings-in-...

And with that, my time at #AMS2026 has come to an end! Thank you for following along with me and for reading my attempts at boiling down some hardcore atmospheric science. Goodbye for now! ☺️ - ATS student, Jared Stickney

On the last day of AMS, I saw this excellent talk given by ATS student Phoebe Lin on “Investigating Smoke Transport and Anvil Microphysical-Radiative Processes within Pyrocumulonimbus Storms”! @ametsoc.org #ams2026

Check out this fantastic talk given by UIUC student Charlie Remmers on “Operational Hurricane Analysis and Forecast System (HAFS) forecasts of supercell structure and evolution during the Hurricane Milton tornado outbreak”! @ametsoc.org #ams2026

AMS reception night was a blast! First, I headed up to CSU’s reception and talked with some prospective students. Then, I visited UIUC’s reception and got to see my undergrad research advisor, Dr. Nicole Riemer for the first time since graduating! @ametsoc.org @climasillinois.bsky.social #ams2026

Check out this fascinating presentation by ATS student Andrew Muehr on the potential sources of air in storm updrafts, and how this may inform their intensity! @ametsoc.org #ams2026

UIUC student Jared Emmert gave an excellent talk on convective environments in medium-range convection-permitting forecasts in global Model for Prediction Across Scales (MPAS)! @ametsoc.org @climasillinois.bsky.social #ams2026

Check out this fantastic satellite imagery of Hurricane Melissa from Dakota Smith’s AMS talk this morning! Satellite imagery is just one of the many useful tools that CIRA makes for the public. Wonderful job combining stunning visuals and science, Dakota! @cira-csu.bsky.social @ametsoc.org #ams2026

I stopped by MIT student Divya Rea’s poster about the termination of heatwaves and was absolutely amazed by how thorough and understandable her presentation was! @ametsoc.org #ams2026

One of my favorite talks of the day so far! Dr. Patricia Cleary from University of Wisconsin-Eau Claire talked about the (amazingly named) Wisconsin’s Dynamic Influence of Shoreline Circulations on Ozone (WiscoDISCO) field campaigns. @ametsoc.org #AMS2026

Check out this awesome poster by ATS student Anastasia Tomanek about a field campaign she was involved in this past summer, In-situ Collaborative Experiment for the Collection of Hail in the Plains (ICECHIP). @ametsoc.org @nsficechip.bsky.social #AMS2026

Helping out with ATS’ Graduate School Fair booth at the Student AMS Conference last night was so fun! I loved talking to prospective students and sharing my passion for atmospheric science. Thank you to everyone who showed up and asked great questions! @ametsoc.org #AMS2026

Nothing like some January convection. The flight to Houston had some gorgeous views! 🌧️ #AMS2026

Hi everyone! My name is Jared Stickney, and I am a Master’s student at ATS in Dr. Jeff Collett’s group. I will be doing a takeover of the ATS socials for some live posting of the AMS 2026 conference in Houston, TX. Stay tuned for some awesome science updates! ⚡️

“The winter of 1976-77 is generally thought to be the worst snow year in our mountains but the SNOTEL network wasn’t built out yet at that point, so it’s hard to make direct comparisons...But the fact that we’re even in the same conversation with that winter is not good news.” (Summit Daily)
