Cajun, Could you or Scott please post a link to a layman's guide to interpreting soundings? Looking at the graphs that are posted on this site, as well as others, it looks logarithmic to me. I know there are sites that get really in depth, but I don't have the time to get into a lot of study. I just want to find "The Idiot's Guide To Soundings" TIA

Watching the news here in Mobile Sunday night, I saw two weather reports. Matt Barrentine of WALA went into a bit more detail, mentioning isolated tornadoes and the risk, but didn't really hype it. Melissa Constanzer of WKRG mentioned concern for Tuesday and Tuesday night, but didn't go into as much detail and hype either. The ones really hyping this up are the message board community. One I only read had one talking about how this may be an outbreak for the Gulf Coast and Carolinas that will be remembered for a long time. One talked about recorded EF4/5 tornadoes recorded in the New Orleans/Baton Rouge forecast area. I admit, seeing that has nerves a bit rattled. Hopefully this doesn't live up to their hype.

Local tv mets usually don't hype storms so early, unless there's a near certainty it'll happen. They have to watch out cause the public will burn them if they are wrong. This is a good thing though. We can talk about the possibilities freely here, cause that's what we do, we talk about the possibilities. You will have under-hyping in TV and over hyping on the Internet. The truth is somewhere in between.

...THERE IS A MRGL RISK OF SVR TSTMS FROM EASTERN TX TO PARTS OF EASTERN GA AND NORTHERN FL...
...SUMMARY... SEVERE THUNDERSTORMS WITH ALL HAZARDS WILL BE POSSIBLE BEGINNING EARLY TUESDAY IN SOUTHEAST TEXAS AND THEN SPREADING EASTWARD ACROSS LOUISIANA...MISSISSIPPI...ALABAMA AND THE FLORIDA PANHANDLE THROUGH EARLY WEDNESDAY MORNING.
...GULF COAST STATES...
AN INTENSE MIDLEVEL SHORTWAVE TROUGH WILL TRACK EASTWARD FROM TX ACROSS THE GULF COAST REGION ON TUESDAY. A 100+ KT MIDLEVEL JET STREAK WILL OVERSPREAD THE NORTHERN GULF COAST AND PIVOT NORTHEAST INTO CENTRAL AL/WESTERN GA BY WEDNESDAY MORNING. AT THE SURFACE...LOW PRESSURE OVER EAST TX/WESTERN LA WILL LIFT NORTHEAST ACROSS THE LOWER MS VALLEY WHILE RAPIDLY INTENSIFYING.

It has been quite a while since an enhanced outlook has shown up
All of my post, unless stated otherwise are opinionated and are in no way an official forecast.
I wanted to note that I was the one that posted the tornado history because someone brought it up AND weather history for our area is somewhat of a passion of mine. I want you to take two things from the post. 1) Knowing your area's local weather history is important 2) Violent tornadoes in south Louisiana are VERY rare. That does not correlate to this event necessarily. Just an observation. Here is the quote
As a note about South Louisiana from the LIX writeup on the violent LaPlace LA tornado ...
The violent tornado touched down at 1:05 AM CST on Dec 6, 1983 ... Violent tornadoes are rare in the central Gulf Coast region. Since 1950, only three violent tornadoes, (F4/F5) have been recorded in the Parish/County Warning Area served by New Orleans-Baton Rouge Weather Forecast Office. Besides the LaPlace tornado, the other F4 tornadoes that have documented in the area since 1950 were : Oct 3, 1964 – A violent tornado associated with Hurricane Hilda struck Larose, Lafourche Parish, killing 22 people and injuring 354 people. Jan 10, 1975 814AM - a violent tornado moved across portions of Amite and Pike Counties in southwest MS . 9 people were killed, and 210 injured.
If you count the Amite-Purvis tornado in 1908, that makes 4.

Question. I've see. Forecasts in the path be supposedly suggestive of tornados in the Baton Rouge vicinity but they never materialize. What does it look like this time around and what makes this event so different?
Also we have a lot of rain coming today. Will cloud cover limit potential in Baton Rouge?

stormydds: Thanks for your reply... as usual

Zack Fradella: Yea, Lezak had a paper peer reviewed and published a year or so ago.
Nov 5, 2022 9:03:24 GMT -6
stormydds: Thanks for your response. I felt that is the case. that's too bad. Has there been any peer reviewed papers on the LRC hypothesis?
Nov 4, 2022 14:01:51 GMT -6
Zack Fradella: Not sure, the LRC is something that takes a lot of work to follow and keep up with. It's not as easy as looking at the parameters and making a forecast. This deters many from even giving it a chance. Also, there is some doubt from the weather world.
Nov 4, 2022 3:38:49 GMT -6
stormydds: Zack, a friend had a meeting in Lafayette which Rob Perillo spoke.He asked him why the LRC is not used to forecast hurricanes by NOAA.His answer was that Lezak won't share the info.I saw the podcast you and David made with Gary.He seemed open.What gives?

PinkFreud - Nola FQ: Been unblocked. Dylan says that the station took major damage, so no idea when they'll even be able to stream again, or be on the air. Hopefully, they will at least let their employees deal with their own property issues!

PinkFreud - Nola FQ: According to another met on twitter, the kitten was rescued by a producer who's adopting it. Of course that hasn't stopped the angry mob, with torches and pitchforks, who are insisting that it's a lie.
