Members of my research group are presenting this week at the @ametsoc.org Madison summit for #32SLS! First up tomorrow (Tuesday) morning is @shearcoincidence.bsky.social on comparing observed and simulated rain and hail size distributions from @nsficechip.bsky.social: ams.confex.com/ams/2026Summ...

@tedmwx.bsky.social @stephanieway.bsky.social did you see this?

There is a reason the US Space Force has lightning launch commit criteria that must be met for weather to be GO for launch. Rockets can trigger lightning by amplifying the electric field and you certainly don't want to blow up a rocket with most of its fuel via lightning strike.

Hi all, #32SLS is just around the corner (a week away)! It's not too late to make a submission for a video or slideshow, and we need more! It doesn't have to be professional-grade or even particularly polished. See the submission portal linked below for details and @tornatrix.bsky.social

#32SLS attendees: Do you have amazing, interesting, or unique weather video or slideshow to share? Please submit it to SLS Video Night! forms.gle/Eb1mo58rcwVY... As SLS is part of the AMS Summer Meeting this year, we'll have an extra-large audience! @meteodan.bsky.social @ams-sls-stac.bsky.social

Today's FORTRAN tip. When editing IF statements, make sure that you don't add "THEN" to what is actually a *logical* IF statement with a continuation "&", so that it *looks* like it should be a standard block IF (i.e. IF-THEN-ENDIF). Confused the hell out of me, the compiler, *and* an AI agent.

Want to see how smoke affects temperatures without seeing any temperatures? Away from the thicker smoke, enough sun came through to warm up the ground to create cumulus clouds (and even storms). But areas with thicker smoke weren't as warm, and so those puffy clouds didn't form.

Awesome example of convective initiation from a differential heating boundary!

Philip Burt@capecodweather.net · 3w ago

This is neat - showers and t-storms firing up west of Chicago along the thermal boundary caused by smoke and no-smoke. Weather doing cool things.

UPDATE: NOAA has fixed the issue with GOES-19 and is planning to restart the satellite. My sources tell me it should be back online in the next 4-6 hours --> www.ospo.noaa.gov/data/message...

Michael Lowry@michaelrlowry.bsky.social · 3w ago

In addition to two areas flagged by NHC today, we need to talk about the big outage for our main hurricane tracking satellite, which went offline late yesterday. We don't have any recovery timelines yet, so for now we're relying on flanking satellites. ⬇️

Um… Thats… not good? Hope it’s nothing serious…

Andy Snyder@wxandbiscuits.bsky.social · 3w ago

The GOES-East satellite images of wildfire smoke many have been sharing have not updated in two hours, due to an unknown issue with the satellite. No ETR according to NOAA.

Smoke forecast for tomorrow afternoon. Seems lovely.

It's like dusk in Albany right now with a very thick layer of smoke blocking out the sun and an orange tint to the sky. Approaching the same feel as June 2023. Smells like campfire outside.

Two years from today Dragonfly will be sitting atop a rocket at the cape. With any luck weather will be green, the go no go poll will be all go and we will be on our way to Titan.

New tornado watch til 10 pm CT with high probs of tornadoes and sig tors

The NWS Storm Prediction Center will be going live on YouTube at 3PM CT this afternoon to discuss today's severe weather threat. Be sure to subscribe to their channel to be notified when the live stream begins: www.youtube.com/@NWSSPC

The ongoing MCS in IL is quite a bit more robust and intense than previous CAM depictions. At this point I think it is likely to pay a much bigger role in today's severe potential than I had thought yesterday, especially in IN where there may not be enough time to recover ahead of the second round.

The severe wx setup in the Midwest for Wednesday is one of the more impressive I have seen in a long time, with a springlike system mixing with summertime heat and instability. PTC1 also is a big flash flood threat for The Gulf region, particularly from SE TX up into MS. tinyurl.com/bdekjztt

Serious severe weather and tornado outbreak likely in Midwest on Wednesday

NHC initiates advisories on disturbance near Texas/Mexico border, expected to bring major flash flood risk to Gulf Coast region next few days

Forecast soundings along warm front in IL and IN tomorrow are insane. Don't recall the last time I've seen > 100 kts of 0-6 km shear with an unstable thermo profile (below is from NAM 3km, but HRRR is similar). Multiple CAMs showing intense supercells training along or just north of the warm front.

A few unprocessed photos from our chase yesterday in northwest IN. Not my best. Distance and lighting were problematic, and was dealing with a fogged up lens at times. It was tough keeping up with the storm. But it was a good chase nonetheless.

TOTALLY STRIATED @eaps-spottr.bsky.social

We are doing teamwork training in our SPOTTR class today, but privately I’m wondering why we just can’t have the students watch the training videos online by themselves…

Wake low... what happens when you fall out of bed in the morning -- Bob Schlesinger. Also an interesting feature of many MCS an example signature of which can be seen in my home weather station's pressure and wind time series:

Great, just what we need on top of everything else. Weather station fraud.

Chris Vagasky@coweatherman.bsky.social · 3mo ago

We’ve got this. We’ve got other prediction market gamblers creating dialers for ASOSes that prevent pilots from dialing into the ASOS systems. We’ve got farmers clogging rain gauges to get drought relief payments. Leave the weather stations alone!

Testing. Does everyone here see my handle the same as before? I noticed just now on my profile page that it had “Invalid handle”. I went into the settings and set it to my original handle and it seems fine now… weird.

Thanks for visiting and for the excellent talk! It was great to catch up!

Clark Evans@clarkevanswx.github.io · 4mo ago

I enjoyed visiting Purdue this week, during which I gave a seminar on the great modeling work at GSL and had great discussions with students, postdocs, and faculty. Thanks to @meteodan.bsky.social for inviting me, to @tornatrix.bsky.social for the picture, and to everyone for their hospitality!

Really? Nobody?
