I study high-impact weather, help develop high-resolution models to improve weather forecasts, and mentor scientists. Constantly striving to help those around me flourish. My views expressed here are mine alone.
One change from the original proposal: "Select courses supporting federal requirements for meteorology careers, and the undergraduate minors in meteorology and geology will continue to be offered."
The final decision lies with the Nebraska Board of Regents, who will meet in early December.

Thank you for trying to model the beautiful community through your platform, Kyle. Driving through Weld County today, I know there’s a lot of people who view the world differently than me - but they are people, just like I am a person, and I think our shared humanity should transcend division.

When I think about a potential cat-6, I’m not sure it would improve forecasts or understanding. Some in the watch and warning trenches worry it would hurt protective actions by further downplaying risks from storms w/ lower wind speeds. I guess I’m just not seeing what problem it would solve? (3/3)

Classification systems are human constructs, trying to delineate phenomena within a continuous atmosphere. To me, they are most effective when they do more than that - i.e., help spur protective actions, improve forecasts, or improve understanding.

A lot of people don’t get up at or before 6:30a (as tomorrow’s sunrise will be here), while nearly everyone is still awake at 5p (as tomorrow’s sunset will be here). For them, the days will feel shorter and nights will feel longer because they’re awake for less of the daylight hours.

I think Melissa is a great case for physics-driven assessment. The environmental wind shear was relatively high throughout Melissa’s peak, such that the exceptionally warm water *may* have facilitated greater resilience to shear and thus had a non-linear feedback to Melissa’s intensity.

A lot of people I know use Canva these days for that - though I suspect others still use PowerPoint.

It’s definitely better now - has been since Evers was first elected (I’ll never forget staying up until after 3a tracking those results!), and especially after SCOWIS flipped. But for the UW System, it was too late- compounded by Evers spending most of his capital on other issues until this year.

Even with Walker’s election, I was excited to come to Wisconsin because of what it had been for 100 years, as many friends attested. That…was not the Wisconsin I found.

What I thought was left-wing conspiracy thinking early in my time at UWM proved very real as time went on. Those experiences politicized me - and I don’t think there’s much hope of going back barring another drastic political realignment.

I came into Wisconsin in mid-2011, having accepted a faculty position at UWM right before Walker took office. I dealt with 13 years of continual degradation by the right-wing ideologues that ultimately led to the elimination of my program and my departure from the state. (1/2)

Life safety wise, in a warming world, we need more people to take more action at lower SSHWS categories anyway for water. This won’t help more people buy flood insurance, or evacuate. It could theoretically do more harm than good messaging wise. This is my *least* favorite hurricane convo. 😂

Agree with both Kim and Brian here.
I’d also add that Melissa *wouldn’t* have been classified as a cat-6 under this proposed system, either - its max winds were 185 MPH, not 216 MPH. The 216 MPH value was the maximum gust estimate whereas the proposed system relies on max sustained winds.

Speculation on my part but my hypotheses:
1) Residual mid-level shear of 15-25kt kept rainbands from forming on Melissa’s W side. Despite symmetric core, 34-kt radii was very asymmetric due to shear/convective asymmetry.
2) 30-31C SSTs moistening BL dry air n/ core preventing inner eyewall decay.

There were a few times I thought an ERC was beginning, only for it to vanish quickly.
I like @pppapin.bsky.social hypotheses. I'd also look at the radial vorticity profile to see it there was something anomalous about it.
Ultimately, what was missing for an ERC? Someone's PhD dissertation waiting.
