That's a joke a very bad one, that chart is from April 14th 2012 https://www.spc.noaa.gov/products/outlook/archive/2012/day1otlk_20120414_1630.html

Are stormnchasers and meteo people not allowed a sense of humour,  yes, its a joke, but there is quite a lot of excitement over there for this setup.

This is actual for Sunday into Monday.

Just watched this US vid: supercells, tornadoes, flooding, thundersnow. You name it!

Finer detail becoming clear now.

outhern Plains... A classic "second season" severe event appears to be in order for parts of the Southern Plains this afternoon and evening, featuring tornadoes, large hail and severe gusts. The greatest threat will be bound on the north and west by the cold front and dryline, covering parts of OK and north TX. Severe potential should persist into tonight toward the Ozarks/Ouachitas, Arklatex region and parts of north and central TX. For much of the day, the boundary layer across the southern Plains near the front and dryline will remain capped, restricting substantial vertical mixing to the boundary layer, and permitting moist advection amidst heating/destabilization. This capping will be maintained into early/mid afternoon as a modest EML and some relatively warm midlevel temperatures move over the area, downstream from -2 to -4 deg C 500-mb temperatures analyzed over northwest through southwest TX and northern MX at 00Z last night. However, strong height falls and cooling aloft, along with strengthening mid/upper flow and deep shear, will occur mid/late afternoon ahead of the strong mid/upper trough. A north-south corridor of peak/ preconvective MLCAPE around 1500-2000 J/kg should develop from central TX northward to southwestern/central OK. Meanwhile frontal convergence/lift near and northeast of the dryline should act on diurnally weakening MLCINH. By the time of deep convective development (likely in the 22-00Z window), the parameter space over portions of southwestern/central and south-central OK ahead of the front and dryline will support supercells, with surface dew points into the mid 60s F, 50-60-kt southwesterly effective-shear vectors, and a strengthening LLJ that will enlarge hodographs. Effective SRH should be favorable from the outset of first storms' maturity, increasing into the 300-450 J/kg range this evening. This will support a cyclic tornado threat from any sustained, discrete supercells, which also will offer a damaging-hail and severe-gust hazard. The big hodographs also will persist eastward after activity evolves to more quasi-linear modes and backbuilds into parts of north TX, supporting continued tornado potential. Damaging-gust threats should expand eastward and southward as the convection does likewise this evening.

This may be worth a watch later. Webcam with sound just outside Oklahoma City, which looks to be in the epicentre of the forecast action later on

Rinse and repeat today, significant hail along with a few tornado and ending up in a strong squall line

...and the late season fun continues...

Sunday outbreaks expected for the Missisipi area up to the Ozarks.

 

[matty40s]

Bit more detail for today's outbreaks, could be a 3 day event moving ENE.

 

[Eagle Eye]

Tuesday also looks interesting, expecting it to become an enhanced risk at least
