The system is heavily sheared but has good vorticity and likely will keep generating strong convection in the eastern quad. I think recon will eventually find the winds to upgrade it at some point me. Nothing major but I see a low end TS out of this. as mentioned before the motion is interesting and atypical for june.

This one looks like it might get classified

Wild mesovortex action going on this storm!

What’s even more maddening to me is their description of EF-5. The wording they use they don’t even follow during their damage assessment. It does not mention these anchor bolts they always use as reason to not give the EF-5 rating. If they would just simply follow their own words as a guide would immediately get better results when rating these tornadoes.

Great post. Damage ratings and tornado intensity science is just strange to me. Another example (albeit not related to this tornado) is the el Reno tornado being rated EF-3 when there were radar velocities suggesting EF-5 intensity. It seems as if we selectively choose data and ignore other data to rate these tornadoes.

Agree with the upgrade. The data is the data and 140 kts is 140 kts.

Radar presentation of the TN supercell is wild right now

That’s two instances of twin tornadoes today. Definitely something interesting and different this system is providing

03/31/23. Gonna be memorable. Hopefully it cycles or lifts before moving into peoria

Starting to get the feel this day might be remembered…lots of discrete stuff everywhere.. good luck to those chasing band those in the paths of these storms.

My hearts go out to the families who lost loved ones. Historic system producing historic tornadoes.

Take it FWIW, but the system that will cause these events crashed into California yesterday and Monday….and in my 15 years living in Los Angeles it was the strongest system I’ve experienced. Some highlights: - 102 mph wind gust in Valencia, CA - confirmed tornado in Montebello, CA (strongest observed in the Los Angeles area since 1983). Rating still TBD but will likely be assigned an EF-0 or EF-1 based on damage produced - several 60-90 mph wind gusts in San Francisco due to a bomb cyclone that developed at the center of the low pressure system I got my eyes on this one

Seeing the system become a prolific wind maker is not surprising. Two days ago when I came ashore in Southern California it had quite strong winds even after the low had passed

Just gave the family in DFW the heads up. I think this one produces some things today

Another thing of note that was strange with this system in so cal…..very cold. Caused snow in lower mountain elevation and the micro hail I previously mentioned. I imagine that cold element will have some factor in the severe tomorrow but would love a mets thoughts

The system that will cause tomorrows event just crashed ashore here in Southern California. Micro sized Hail and strong winds (even continuing on the backside of the low). I’d watch out tmr.

Following this now. Stay safe to those in the affected path

Maybe we can move all the other posts here? Might get confusing with 2 threads

Following this now. Look forward to the updates and stay safe to those in the affected regions.

Its not as simple as a Cat 1 can cause this much surge. This was not an ordinary Category 1 storm. it was extremely large, and on top of that was interacting with a very strong high pressure system. Those two elements created a strong pressure gradient that delivered a 200 mile swatch of NW 50-60 MPH winds that drove insane amounts of water into the FL coast. A similar Cat 1 storm (Katrina) was in a similar situation and evolved much differently as a storm with respect to storm surge. There have been several hurricanes that have greatly overperformed their storm surge values due to extreme large fetch of winds (Ike, Nicole, Sandy, etc).

This doesn't make any sense. Having 100 MPH flight level winds does not make a storm a hurricane. The lack of sustained 60+ MPH winds anywhere near the coast suggests this did not have 75 MPH sustained surface winds. It is possible for a storm to be stronger aloft and weaker at the surface. It is also possible for a storm to have weaker flight level winds and have the winds mix down better. Nothing I am saying here downplays Nicole as a storm.

Has anyone checked to see if Turtlehurricane is ok? I can't imagine the dissapointment. Storm underperformed my expectations....agree this was not a cane at landfall.

Appreciate yall

any good radar sites
