Yep. Great presentation!

@mattlanza.bsky.social @wallywx92.bsky.social Here are some HYSPLIT back trajectories from a presentation NG and I gave. At low-levels, you can see the source region is near the keys/Caribbean. At mid-levels, you can see some potential influence from Barry and Flossie (East-Pac).

I have some Hysplit back trajectories somewhere. Let me see if I can find them.

Interested in hurricanes? I want to introduce TC-ATLAS: the Tropical Cyclone Analysis Tool for Live and Archived Structure. Explore live or past storms without writing a line of code or downloading a data file, building on the capabilities of TC-RADAR: michaelfischerwx.github.io/TC-ATLAS/ind...

"We conclude by advocating for greater recognition and support from the Weather Enterprise ... to continuously develop training content and materials that enhance intercultural and multilingual weather communication, thereby strengthening [broadcast meteorologists'] vital role in public safety."

New paper alert!

Attached is a special sounding launched at 2031Z March 15th, 2026 from College Station, TX valid at 21Z. Data has been sent to be assimilated into the models. Launch ahead of both the dry line and cold front currently working through central Texas.

Attached is a special sounding launched from College Station, TX at 2033Z March 6th, 2026 valid at 21Z. Data has been sent to be assimilated, and the TEMP data should hopefully show up on the new University of Wyoming soundings page. @nws.noaa.gov

Wow! Officially the biggest snowstorm in RI history. Providence will make a run at 40 inches

Special sounding launched from College Station, TX at 2028Z February 14th, 2026 valid at ~21Z. This was launched just ahead of the convective line. Warm nose from last sounding has eroded and low-level hodograph is impressive.

Special sounding launched from College Station, TX at 1730Z February 14th, 2026 valid at 18Z. Skies were a bit overcast with some slight clearing occurring since launch. 21Z balloon is planned.

Never thought I would be involved in a paper on the cover of @science.org! It was awesome being involved in this collaborative project.

🚨 🚀 A crude interface I built to expose an archive of College of DuPage GOES imagery since about 15 Apr 2017. The archive is around ~500TB in size over ~2.5 billion JPEG images. Yikes, but here you go.

Anyways happy for feedback. Not worth the effort?

Yesterday, Suomi-NPP passed over Tropical Cyclone Dudzai and its central eye.

This was very fun to work on, emerging from student class projects a few years ago. How sharp can a cold front get? We were able to point to some answers.

This entire train got blown over this morning northwest of Cheyenne

Attached is a 1949UTC special sounding from College Station, TX. Balloon was launched between the initial round of storms and ahead of the main frontal boundary. There is some convective contamination between ~540mb and 450mb, as we hit an updraft at this point.

Below is a November 19th, 2025 1714 UTC special sounding launched as part of our ATMO-251 class from Texas A&M's campus. Sharppy image and sharppy file are attached. Mixed layer parcel is also plotted. Launch was done as morning stratus deck was clearing.

Annotating a long 3+ day loop of #Hurricane #Melissa from Kingston, #Jamaica radar.

2️⃣ periods appear where an eyewall replacement cycle, #ERC, looked underway. In both cases, inner eyewall stayed intact & outer bands merged, resulting in a larger eye & strengthening after.

A remarkable evolution 🌀

The Copernicus Sentinel-2 polar-orbiting satellite made an extremely fortuitous pass over Hurricane Melissa right before it made landfall in Jamaica to provide these stunning images of one of the most powerful Atlantic hurricanes in history

I was worried for my crew mates when I saw them circling in the eye for over 20 mins. Looks like the very rough ride was confirmed. Plane had to leave early. They reported svr turb and a "sawtooth" eye. Looks like they moved 600-700ft up & down during this stretch in ~1 min.

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.

Looking back at the rapid intensification of #Melissa, two things really stand out to me:
1) there were *5* consecutive six-hourly periods of RI
2) an RI period began when the storm was already at Category 4 intensity

The red entries here highlight when an RI period began (30+ kt in 24 hr).

1-minute #GOES19/#GOESEast Visible and Infrared images with plots of GLM Flash Points showed prolific lightning activity within the inner eyewall of Category 5 Hurricane #Melissa as it approaches the SW coast of Jamaica. Low-altitude mesovortices persist within the eye.

A 10am EDT update from the National Hurricane Center now puts Melissa's sustained winds at 185 mph. Full text: www.nhc.noaa.gov/text/refresh...?

This is hands down the most extraordinary dropsonde in Atlantic recon history.
