AREAS AFFECTED...CENTRAL/NE MS AND NW AL

CONCERNING...TORNADO WATCH 108...

VALID 282049Z - 282215Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 108 CONTINUES.

SUMMARY...DANGEROUS TORNADO OUTBREAK UNDERWAY WITH MULTIPLE
SUPERCELLS CAPABLE OF PRODUCING LONG TRACK...STRONG/VIOLENT
TORNADOES NEXT FEW HOURS.

DISCUSSION...MULTIPLE DISCRETE AND CLUSTER SUPERCELLS ARE MOVING
NEWD FROM CENTRAL MS INTO NW AL. RADAR AND SPOTTER REPORTS HAVE
CONFIRMED A DAMAGING TORNADO NEAR TUPELO MS IN THE PAST HOUR...WHILE
OTHER MORE DISCRETE STORMS HAVE FORMED FARTHER TO S INTO CENTRAL MS.
ALIGNMENT OF THE STORM INITIATION AND SPACING OF THE STORMS IN
CENTRAL MS SUGGEST THAT THESE STORMS WILL REMAIN DISCRETE FOR
SEVERAL HOURS...SUPPORTING THE POTENTIAL FOR LONG-TRACK TORNADOES.
ADDITIONALLY...LOCAL VWP/S HAVE SHOWN THE EXPECTED STRENGTHENING OF
WIND PROFILES AND SOME BACKING OF LOW-LEVEL FLOW ASSOCIATED WITH
SURFACE PRESSURE FALLS...WHICH IS BOOSTING EFFECTIVE SRH TO NEAR 300
M2/S2. STRONG TO VIOLENT TORNADO DAMAGE WILL BE POSSIBLE WITH THE
MOST INTENSE SUPERCELLS THE NEXT FEW HOURS

A extremely large and violent tornado likely just went through Louisville MS. Debris is falling on the chasers near there and also eariler on CNN's team heading for Tupelo. CNN BTW is doing an awful job right now, not covering it properly and mis-using terms everywhere. Appalling and reminds me of their coverage on April 27, 2011.



The amount of action in this part of MS is incredibly impressive. Shocking action.

These supercells are the most impressive I've seen since 2012 in terms of #. Best sigs too. I would think more would be posting but...

Hey, maybe they'll find MH370 in Tupelo, then they'll be all over it.

Clinton is in the path of the storm Take cover Bill !!!

[windnrain]

So I understand what capping is and have a basic understanding of severe weather... where might be a map where I could look at values that would indicate different levels of capping?

[Tireman4]

Eerily, this reminds of April 2011....

[CrazyC83]

Louisville may have been hit TWICE. A cell merger took place just after it passed, with a new cell being directed into Louisville as an intense tornado.

[CrazyC83]

So I understand what capping is and have a basic understanding of severe weather... where might be a map where I could look at values that would indicate different levels of capping?

Look at soundings from local sites. Those will help find where such exists. I would say south of I-20 is mostly capped right now.

[AdamFirst]

Tornado warned cell with a clear radar signature heading straight for the northern Jackson, Mississppi metro

[CrazyC83]

Pure speculation, but looking at Tupelo images, looks like EF-3 to maybe low end EF-4.

[Extratropical94]

Tornado emergency up for Athens, AL and Northern Huntsville, AL
