Very high STP over all AL for this evening.

Will probably have a derecho for GA later on as the MCS / QLCS moves east.

...and the sun just came out in Huntsville...looks like an interesting day for north and central Alabama...

[Dave]

Cleared two tornado warnings out up here for Northern Ky, south of Cincinnati this morning. The Greater Cincinnati/Northern Ky airport was shut down and evacuated until the northern most warning was cleared. No damage...1 report of 65 mph wind gust only. The sun is out now but I'd preferred to see it stay cloudy today. May be an interesting afternoon.

Tonight's set-up looks nasty yet again. What's worrying as well is that it looks like the weekend might be quite eventful, too. UGH.

THE NWS STORM PREDICTION CENTER HAS ISSUED A
TORNADO WATCH FOR PORTIONS OF

EXTREME SOUTHEAST ARKANSAS
NORTHEAST LOUISIANA
MUCH OF MISSISSIPPI

EFFECTIVE THIS WEDNESDAY MORNING AND EVENING FROM 1105 AM UNTIL
700 PM CDT.

...THIS IS A PARTICULARLY DANGEROUS SITUATION...





DESTRUCTIVE TORNADOES...LARGE HAIL TO 4 INCHES IN DIAMETER...
THUNDERSTORM WIND GUSTS TO 80 MPH...AND DANGEROUS LIGHTNING ARE
POSSIBLE IN THESE AREAS.

THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 65 STATUTE
MILES EAST AND WEST OF A LINE FROM 45 MILES EAST SOUTHEAST OF
NATCHEZ MISSISSIPPI TO 50 MILES NORTH OF TUPELO MISSISSIPPI. FOR
A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH
OUTLINE UPDATE (WOUS64 KWNS WOU2).

REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
TORNADOES AND SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
AND POSSIBLE WARNINGS.

OTHER WATCH INFORMATION...CONTINUE...WW 229...WW 230...WW 231...

DISCUSSION...A VERY VOLATILE SETUP IS DEVELOPING FOR PORTIONS OF MS
LATER TODAY AS A MOIST AND VERY UNSTABLE AIR MASS RETURNS INTO AN
AREA WITH IMPRESSIVE LOW LEVEL AND DEEP LAYER VERTICAL SHEAR
PROFILES. ACTIVITY IS CURRENTLY DEVELOPING OVER SOUTHEAST
AR/NORTHEAST LA. HOWEVER...IT APPEARS THE PRIMARY CONCERN WILL
START BY EARLY AFTERNOON OVER CENTRAL/NORTHERN MS WHERE DISCRETE
TORNADIC SUPERCELLS ARE LIKELY. ALL PARAMETERS SUGGEST THAT
STRONG/VIOLENT AND LONG-TRACK TORNADOES ARE POSSIBLE. VERY LARGE
HAIL AND WIDESPREAD DAMAGING WINDS ARE ALSO A CONCERN.

AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
SURFACE AND ALOFT TO 4 INCHES. EXTREME TURBULENCE AND SURFACE
WIND GUSTS TO 70 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO
550. MEAN STORM MOTION VECTOR 25040.

The STP in MS is insane.

This should advect into AL later as the shortwave goes negative tilt.

This could be epic.

So, GCANE, you think, James Spann better taking a nap, or ?

So, GCANE, you think, James Spann better taking a nap, or ?

LOL, that's a politically loaded question.

Actually, I am working an idea that all this severe weather could be related to ionospheric effects.

[Bunkertor]

Yeah, why not. You gotta find a way to fire a sonde there and how to print the hodographs then...

My problem is, that the Clasico sicks off in 1,5 hours...

Wow, I can't ever remember tornado probs this high here ever. I'm southeast of the 45% zone thankfully but still.
