Severe WX December 29 & 30, 2021 Severe Threat

I’d also keep an eye on the cell near Winona, MS actually. Not much in its way, has a more robust appearance, and looks like it’s trying to get a meso going.

New cell just blew up east of the Tupelo one not far from Hamilton, if those can take root they will be in prime position to take advantage of the significant thermal boundary draped across the TN Valley. Could be a long-term issue for Decatur or Huntsville if they get going

Apparently the NWS told Congress last year that the swiss cheese radar coverage in places like Mississippi has "no significant negative impact” to their ability to issue warnings. I guess that's why they figure the horrible radar coverage is "good enough" and they choose to get by with it.

The cell north of Canton, MS is looking impressive as well.

Waff just mentioned a possible rotating wall cloud with the storm south of Tupelo. Maybe from twitter or NWS chat?

Yup that one looks like trouble. The others closer to the boundary aren’t taking off as much though.

The cell above has broad rotation on a small cell but the one near Duck Hill is cranking up

Kind of a snoozer so far, but SPC says don't let your guard down just yet:

I will take a snoozer! lol

 

[Austin Dawg]

There is a small cell around the state line northwest of Hamilton that is trying to crank up

 

[Clancy]

SPC says chance for isolated supercells highest over south-central TN, NW AL and NE MS.

Storm east of Tupelo looks like it's starting to hook.

 

[buckeye05]

The Tupelo cell has been threatening and trying to wrap up for a while now, but has so far been unable to do so.

Temp in the Shoals area is around 60F. High was supposed to be in the low 70s. Will these much cooler than forecast surface temps reduce the severe potential for this area?

Seems to be a problem with forcing, as well as too much morning convection. I'll be interested to see if this turns about being one of those events where, while initially appearing impressive, discrete storms never quite take off before being overtaken by the main line.

Mostly blue skies here in MS. It’s eerie outside!

 

[OHWX97]

Tornado warning issued for the cell passing north of Walthall, MS. The cell trailing behind it also looks problematic.

 

[Austin Dawg]

OHWX97 beat me to it​

I strongly agree. I don’t think this event is going to reach its ceiling of potential.

Very strangely shaped polygon that narrows to a point on the northeast end.
