CAPE and your Thermo assumptions, a 🧵.

TL;DR - High CAPE is still notable, but the upward velocity of the parcels guarantees the kinetic energy will never match the potential energy in the Skew-T. Yet another reason CAPE is overrated. Sort of. (1/22) We’ve all done our Skew-T homework and can draw how a surface parcel will rise to the heavens. We’re all hoping to see that line be as far to the right as possible. Can our CAPE get to 3000? 5000? omg, 7000?!!!!

Bad time for a thread (it's late EDT). But I'm going through WFO twitter activity during big storms.

There are offices that basically relying on bots. There are those who mix in bots and radar.

And there are a couple who stand out; who are unlike the others. And it shows. Lets go to May 20. That was the high risk day. Things have gotten going. Watch at 1:45pm. Storms by 2:30pm. Most offices in this situation bury themselves in warnings and zoomed in radar loops around those warnings. And they stay there from beginning to end of the event.

I gave a talk yesterday at the @NWSJacksonville IWT meeting. I discussed what I see as the likely future of where the field of meteorology is going in terms of communicating forecasts and safety. I would like to share those thoughts here. 1/n @NWSJacksonville The goal of NWS and broadcast mets, EMs, first responders, and elected officials in using social media to share weather information is the same now as when we first started using it. The goal is to save lives! (Extra credit if it also helps make recovery easier.) /2
