5 tornado warned cells in MS right now. The one SW of Yazoo City looks most menacing.

Kinda just sitting here waiting for the upgrade to HIGH, really - cells getting to the business end of things much quicker than yesterday.

That was long, long overdue. Considering the SPC themselves said that Tuesday looked to be the most potent of all the days, it made no sense to have slight there.

I leave my buckle undone so I fly off the rails when something happens.

We're already at 5 TOR warnings right now so this is a much faster start than yesterday. I'm amazed since there was so much pre-convection too in that spot. Area's not affected will be a power-keg. Its to the point that we should only start posting confirmed tornadoes now.

That Yazoo signature is scary.

#286 Postby **Alyono** » Mon Apr 28, 2014 2:07 pm

Yazoo's signature looks to have weakened based upon the latest scan

#287 Postby **ronyan** » Mon Apr 28, 2014 2:08 pm

Yep it is headed straight for Yazoo, they probably have 10 minutes or so.

Let's hope it stays that way.

REPORT via TWC: Very large tornado on the ground with that cell.

Cyclenall · #289 Postby **Cyclenall** » Mon Apr 28, 2014 2:10 pm

Wow, look at that! :eek:

The Yazoo supercell is looking like monster already with a defined hook meaning a tornado is on its way or is already on the ground :double:

. New sups might be forming south with appendages already showing, could be very explosive and dangerous.

No surprise here.

MESOSCALE DISCUSSION 0455
NWS STORM PREDICTION CENTER NORMAN OK
0209 PM CDT MON APR 28 2014

AREAS AFFECTED...CNTRL AND NE MS...NW AL

CONCERNING...SEVERE THUNDERSTORM WATCH 108...

VALID 281909Z - 282015Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 108
CONTINUES.

SUMMARY...TORNADO THREAT IS EXPECTED TO CONTINUE TO INCREASE LATE
THIS AFTERNOON AS NUMEROUS TORNADIC SUPERCELLS DEVELOP ACROSS PDS
TORNADO WATCH 108. THE AREA FROM CNTRL MS EXTENDING NEWD INTO NW AL
WILL BE UPGRADED TO HIGH RISK AT THE 20Z OUTLOOK.

DISCUSSION...SUPERCELL THUNDERSTORMS ARE CONTINUING TO DEVELOP
ACROSS CNTRL AND NRN MS THIS AFTERNOON IN RESPONSE TO STRONG UPLIFT
AND DESTABILIZATION. THE ENVIRONMENT IS CHARACTERIZED BY MODERATE
INSTABILITY...STRONG DEEP LAYER SHEAR AND SUBSTANTIAL LOW-LEVEL
SHEAR. THE WSR-88D VWPS IN CNTRL AND NRN MS SHOW LOOPED HODOGRAPHS
WITH 0-3 KM STORM RELATIVE HELICITIES IN THE 450 TO 500 M2/S2 RANGE.
THIS SHOULD SUPPORT A THREAT FOR STRONG TORNADOES AS SUPERCELLS
CONTINUE TO INTENSIFY. DUE TO THIS IMPRESSIVE SHEAR ENVIRONMENT...AN
OUTBREAK OF TORNADOES APPEARS LIKELY AND THE AREA FROM CNTRL MS
EXTENDING NEWD INTO NW AL WILL BE UPGRADED TO HIGH RISK FOR THE 20Z
OUTLOOK.

of course, it could have cycled before moving through Yazoo City, dualpol was not showing any debris SW of Yazoo

The moment they saw those new cells firing along with the Yazoo one, they pulled the trigger in their minds. Using very strong wording in that one, moreso than the rest today too.

I think he means the supercell is a beast, not that the tornado is strong...for now.

#298 Postby **Alyono** » Mon Apr 28, 2014 2:24 pm

given the dual pol, I wonder if the tornado was even on the ground with the Yazoo City storm

Cyclenall · #299 Postby **Cyclenall** » Mon Apr 28, 2014 2:26 pm

I see some type of radar hole with that Yazoo supercell on the Wunderground radar ...not sure what its showing as of 2:23 CDT.

#300 Postby **ronyan** » Mon Apr 28, 2014 2:27 pm

The rotation has intensified now with the latest scan, not sure how Yazoo city fared. They may have escaped the worst with a cycling of that storm.
