Very strong wording in the latest SPC D1 Outlook!:

"THIS IS AN UNCOMMON, UPPER-ECHELON PARAMETER SPACE. IN SUCH AN
ENVIRONMENT, ANY RELATIVELY DISCRETE SUPERCELLS WILL BE CAPABLE OF
MULTIPLE TORNADOES, SOME LONG-TRACKED AND STRONG TO VIOLENT (EF2-5
POSSIBLE), WITH CONSIDERABLE DESTRUCTIVE POTENTIAL. A VERY MOIST
BOUNDARY LAYER ALSO WILL REDUCE POTENTIAL COLD-POOL/OUTFLOW STRENGTH
VIA LESS SUBCLOUD EVAPORATION, SO THAT EVEN CLOSELY SPACED STORMS
MAY HAVE SUBSTANTIAL TORNADO THREATS. FORECAST WIND FIELDS AND
MODEL SOUNDINGS REASONABLY SUGGEST ANY SUSTAINED SUPERCELLS AND
THEIR TORNADOES WILL BE FAST-MOVING (45-55 KT), WITH INDIVIDUAL
TORNADO PATHS NEARLY AS LONG IN MILES AS THEIR DURATION IN MINUTES."

One of the most strongly worded SPC discussions I have ever read for sure.

I have NEVER read a wording like that. This feels like when I was living in Memphis. During the Super Tuesday outbreak, I heard Dave Brown say "folks, I've just been handed a Tornado Emergency for Shelby County." The first time he said he ever said that.

I think this is a very important statement.

Edwards is one of the best.
