Well, the line is starting to approach the warned area an hour after this first issued the warning....

The warning indicates the severe thunderstorms are from the top centre of the warning to the bottom centre of the warning. This is really interesting, but indeed they may have it up because of the explosive development ongoing and approaching. I wonder if they are going to reissue in a minute.

Edit: expired

I just came here to post about this. I've never seen anything like it.

edit: Could it be the office protesting the lack of a watch being issued? Struggling to find an explanation for this one.

I think LWX (Sterling) railed in an AFD about the lack of a watch last year...and LWX ended up being proven right as they had to issue a short-fused watch as severe wx popped in their backyard.

Something has to be up.. if these are legitimate, several people need to be fired immediately. It's not even the size of the warning that's most apalling.. it's the lack of any severe criteria.. they had "golf ball sized hail" in the wording too.. storm tops at 20kft.. please for the love of humanity let this be a mistake

According to Kevin (at TNWx), both warnings violate issuance regulations, as no more than 12 counties or parrishes may be included in a single warning.

There are warnings that have had over 12 counties in them. I'm looking at one right now with 15 counties from NWS Paducah 05/25/11

The directive states this (at least the copy I have)...I do think its a recent addition though (within the last year)....

WFOs shall limit the number of counties/parishes in a SVR to 12 or less

Disregarding that point though...there are so many things that were wrong with that...its hard to know where to begin...

Morristown is usually a pretty good office, especially with severe weather. This is

a bit of a shock to me that they would disregard the memo from the Warning

Decision Training Branch.

On another note, Nashville with another quick trigger-pull for a TOR. That department

did not verify too well for them on January 23rd.

The NWS directive (page 5 on the link below) does have this mentioned. Note the word "should" though. 30 is unreal!

2.3.4 Content. WFOs should limit the number of counties/parishes in a SVR to 12 or less

Why no warning then?

A rotating wall cloud is not that uncommon for storms in their (Hunstville) area.

The radar data, both velocity and reflectivity, likely does not support the immediate

danger of a tornado, and the warning forecaster is probably going to wait for

more concrete evidence before pulling the trigger on a TOR here.

30 counties included. I wonder what's up.

My county was in that too. Had some lightning from a storm from the north that wasn't even in the huge warning box. I don't think I've ever seen them do that before, especially for just one cell and that one weakened. Now I'm under a flash flood warning.
