@pcavlin @Spacenstuffhtx No problem. Good luck--winter weather forecasting is usually a challenge in the south!

[Vivek Mahale @vmahale]

@Spacenstuffhtx @pcavlin It's definitely possible, but there is bit of higher uncertainty on precipitation type if the DGZ remains unsaturated (see chart). Probably more likely to see a mix in that case.

@slaterweather @JLaDue Both TOKC and KTLX indicate the bands have a horizontal convective roll structure (parallel to the surface winds ).

[Vivek Mahale @vmahale]

@slaterweather @JLaDue The 00Z sounding does show a saturated layer at approx. 850 mb in the dendritic growth zone (DGZ) with steep low-level lapse rates (steep enough to have even some surface instability).

@AaronWxDavis @NWSBirmingham Congrats Aaron!

Radar throwback from yesterday evening (9/24/2024): A supercell produced destructive hail across the Oklahoma City metro.

Note the significant reduction in ZDR (<0 dB) and lowered/noisy CC collocated with high reflectivity (at times >70 dBZ) as the hail fell. #okwx

@MatthewCappucci Thanks Matt--appreciate it!

[Vivek Mahale @vmahale]

Always enjoy giving a guest weather briefing in @ousom's Synoptic Meteorology Lab! Great opportunity to also chat about the future trajectory of the NWS with the next generation of meteorologists.

[Vivek Mahale @vmahale]

@4029Darby @DVDFortyTwo Yes—from the cases I’ve seen, it seems more likely to be seen nearer to the surface/closer to the radar.

[Vivek Mahale @vmahale]

Want to learn about tornadic supercells with low-reflectivity hooks? Check out my showcase during this afternoon's session! #NWAS24.

[Vivek Mahale @vmahale]

@4029Darby Thanks Darby--appreciate it!

[Vivek Mahale @vmahale]

@4029Darby Good question! Unfortunately, I’m not 100% sure. An NWS meteorologist that came by my poster from a southeast office did say they have seen them before. The radar image is from Kansas.

@ThomasGeboyWX Thanks Thomas!

[Vivek Mahale @vmahale]

@schwent03 Thanks Thomas! It was great to meet you in-person.

[Vivek Mahale @vmahale]

@OHWXisweird Unfortunately, only those registered for the conference can view the presentations. However, my one page summary captures the essence of my showcase presentation.

[Vivek Mahale @vmahale]

@samgardner_4 @ScottTGL1 These can definitely be challenging! It’s important to look for vertical continuity and the texture of the velocity field (i.e., does it look natural with respect to the storm morphology?). Also, these are more likely closer to the RDA, where you’d be scanning below the LCL.

@blamarre Thanks Brian!

[Vivek Mahale @vmahale]

Plenty of people ready to learn and participate at the Warn-on-Forecast System (WoFS) Workshop, including broadcast meteorologists, National Weather Service meteorologists, emergency managers, and students! #NWAS24

[Vivek Mahale @vmahale]

Lots of interesting discussion on the challenges of probabilistic messaging at @madlizzie79 and @wxmanted's showcase "Weather or Not: Overcoming the Pitfalls of Probabilistic Messaging to Improve Decision Making"! #NWAS2024
