1 whiskey drink, 2 beers and a que passa margarita so I no care if it hits chosen valley.
Maybe it will blow away Excelsior House so you don't have a bunch of crackheads living a street or two over from you

I need clarification. Did the NWS not issue a Tornado Warning, or did they issue a warning, but you didn’t receive a notification on your phone?

Landspout is a term created by atmospheric scientist Howard B. Bluestein in 1985 for a tornado not associated with a mesocyclone.[3] The Glossary of Meteorology defines a landspout:
"Colloquial expression describing tornadoes occurring with a parent cloud in its growth stage and with its vorticity originating in the boundary layer.
The parent cloud does not contain a preexisting mid-level mesocyclone. The landspout was so named because it looks like "a weak Florida Keys waterspout over land."[4]
Landspouts are typically weaker than mesocyclone-associated tornadoes spawned within supercell thunderstorms, in which the strongest tornadoes form.
Landspouts are a type of tornado that forms during the growth stage of a cumulus congestus or occasionally a cumulonimbus cloud when an updraft stretches boundary layer vorticity upward into a vertical axis and tightens it into a strong vortex. Landspouts can also occur due to interactions from outflow boundaries, as they can occasionally cause enhanced convergence and vorticity at the surface. These generally are smaller and weaker than supercell tornadoes and do not form from a mesocyclone or pre-existing rotation in the cloud. Because of this lower depth, smaller size, and weaker intensity, landspouts are rarely detected by Doppler weather radar (NWS).[5]
Landspouts share a strong resemblance and development process to that of waterspouts, usually taking the form of a translucent and highly laminar helical tube. "They are typically narrow, rope-like condensation funnels that form while the thunderstorm cloud is still growing and there is no rotating updraft", according to the National Weather Service.[2] Landspouts are considered tornadoes since a rapidly rotating column of air is in contact with both the surface and a cumuliform cloud. Not all landspouts are visible, and many are first sighted as debris swirling at the surface before eventually filling in with condensation and dust.

I see the NWS is now on Facebook with a video of it rotating before formation and are now calling it a landspout
I've never bothered to commit to memory the actual definition of land spout.
I do know at a softball game once I was nearly decapitated by a pop-up tent when an over performing dust devil passed through the park. It took out tents, umbrellas, threw trashcans, kicked up blinding dust, and relocated some ol' baws bama hat a half county away. It was more exciting than the games that day.

They issued a warning, but whatever it was was long gone by the time the warning was issued. It never showed up on radar and NWS Lake Charles issued the warning on public report.

First time I’ve heard of a Landspout.

Makes sense. Those arent going to be obvious on radar bc there is no meso.
Basically stretch the hell out of the boundary layer and it (blah blahing over some things) causes some spin.
Also follows since it appeared to be very short lived.

Tornados don't usually travel northeast to southwest. Generally tornados travel mostly northeast and sometimes due east. If there was significant damage to the southwest then it probably came from an outflow boundary occurring from a dissipating or decaying heavy thunderstorm.

All true. And then there is Jarrell.
