Roughly 150 miles between snow squall warnings and severe thunderstorm warnings. What a dynamic system!

Yeah, it's wild seeing the hail reports from MPING with the snow reports following up shortly after.

 

[TornadoFan]

Tornado warning for Conway, Arkansas.

 

[Kds86z]

Vilonia Ar tornado warning

 

[Clancy]

A strong couplet is visible over Lake Mary, Florida, as this TOR-warned storm moves eastward towards the Atlantic Coast.

 

[speedbump305]

Vilonia, AR is currently under a tornado warning.

 

[TornadoFan]

Tornado warning for St. Louis now.

 

[Clancy]

Small prefrontal cells out ahead of the organized QLCS with embedded mesovortices in Arkansas are organizing and exhibiting some rotation. Still remains to be seen if they will mature into supercells, but they're certainly getting their act together at the moment.

KHUN starting to bite harder on supercell threat:


Area Forecast Discussion
National Weather Service Huntsville AL
317 PM CDT Sun Mar 15 2026
AFD:
"Our previous discussion remains on track. However, HIRES, rapidly evolving guidance has trended more in favor of development ahead of the main line of storms. Therefore, we are now monitoring a medium chance of supercells forming ahead of the QLCS, which will increase our overall tornado threat if realized. We will be closely monitoring this situation as the late afternoon continues."

Tornado warning for St. Louis now.

That looks eerily similar to how the 2025 tornado looked in its developing stages…

 

[speedbump305]

Think we may see a tornado on the ground around the St. Louis area shortly.

 

[Clancy]

Now have two mesos on that Conway, AR storm, could have a handoff eventually.

 

[Clancy]

TOR now for Longview, Texas. Not extraordinarily strong couplet at the moment, but it's definitely there. Occurring within a larger SVR-C issued for the area.

[TornadoFan]

Rotation near Pine Bluff, Arkansas. This is on one of the discrete cells SE of Little Rock.

 

[KevinH]

What KIND of signs though?

 

[jiharris0220]

Already some noticeable mesocyclones in these OWS cells.

 

[Clancy]

Some of those discrete cells are getting "the shape" and now there's at least two rows of small storms visible, with a third in the works.

 

[speedbump305]

The discrete cell NW of Pine Bluff has the look that it may decide to drop something eventually.

 

[speedbump305]

Definitely got a suspicious look to it already.
