Just an update on my chase trip, it’s been absolutely abysmal so far lol. Sitting near Jena, LA watching what are pretty much garden variety thunderstorms. Ah well.

Just happy to check out Dixie and the Plains though. Gonna try our luck in SW Missouri tomorrow, however.

Radar-confirmed tornado in Greene county, AL. Couplet is not much but there is a clear signature on CC from it

EDIT: This seems like one of those "power showers" or small transient supercells(?). I don't know what the correct term for it would be and someone can correct me if they know.

At least 6 is on, but yeah, wouldn't be shocked if there's no one in the studio rn to cover it at many of the stations; this is definitely unexpected

Uhhh I don't think this is right lol but regardless yeah the environment doesn't scream "tornado warnings" at much of any forecastable lead time.

Looks like they're all on except 33/40 now. I was floored when my alert went off.

VWP from Columbus indicates decent speed and directional shear, can assume it's higher in the radar hole where those are

Two more tornado warnings just went up... some feisty little couplets on these cells.

EDIT: the one other than that posted above is an extension of a previous one between the Gainesville and Eutaw area .

Mesoscale Discussion 0477
NWS Storm Prediction Center Norman OK
0441 PM CDT Sun May 02 2021

Areas affected...western Alabama.

Concerning...Severe potential...Tornado Watch likely

Valid 022141Z - 022245Z

Probability of Watch Issuance...95 percent

SUMMARY...Small supercells with a history of producing tornadoes may
continue to pose a risk for brief tornadoes over the next couple of
hours as a warm front lifts northeastward.

DISCUSSION...21z surface analysis showed a diffuse warm front across
western Alabama and eastern Mississippi. Several small supercells
have developed over the last within the deep surface moisture to the
southwest of the warm front. Weak destabilization, MLCAPE around 500
J/kg, will likely continue to support weak convection for at least a
couple of hours. Backed low-level winds along the front are
enhancing low-level shear with 0-1km SRH of 150-200 m2/s2. Hi-res
guidance and observational trends suggest a corridor of tornado
potential will likely exists for at least a couple of hours as
storms move to the northeast along the front. Coverage is expected
to remain low, but a few tornadoes will be possible. Portions of
west-central Alabama will be included in a Tornado Watch being
coordinated across Mississippi.
