Severe Weather for the South Feb 24-25...

[Gorky]

Geez... that couplet looks every bit as bad as the first one to hit Dumas earlier. Looks like it is going to track right over the town again.

I hope they were just somewhere taking over. We watch these storms and people get excited when they see something really intense on radar and I know that nobody wants anyone to get hurt as it's easy to forget someone is likely going through hell when you hear about these tornadoes. I pray nobody was/is killed.

The Dumas Storm moved through here, much weaker.. it did cause warnings to be hoisted though.

[Lindaloo]

Oh my Lord. My prayers going out to the people of Dumas.

[MyrtleBeachGal]

Can someone please tell me what all of this means? I don't think I've ever read this long of a discussion from NOAA before... and I cut the last two paragraphs out...

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON NC
300 PM EST SAT FEB 24 2007

.SHORT TERM /TONIGHT/...UPDATED
ONCE AGAIN BASICALLY A TEMPERATURE AND CLOUD COVER FORECAST FOR
THE SHORT TERM.

MID TERM/SUNDAY THROUGH MONDAY NIGHT/...UPDATED
EARLY SUNDAY ISENTROPIC UPGLIDE IN THE LOWER MID LEVELS OF THE
ATMOSPHERE WILL BEGIN TO PERMEATE INTO THE BOUNDARY LAYER AS A SFC
WARM FRONT LIFTS NORTHWARD OUT OF SC. EXTENSIVE MID CLOUD WILL
LOWER/THICKEN AND THE COLUMN WILL BE ABLE TO SUPPORT PRECIPITATION
FROM WEST TO EAST. IN FACT...SUPPORT FOR PRECIP WILL PROBABLY RAMP
UP VERY QUICKLY DURING THE LATE MORNING AS THE WIND SHIFT FROM ESE
TO SSW ALONG THE BOUNDARY ADVECTS IN MUCH HIGHER SFC DEWPOINTS.
SEVERAL HOURS OF RADAR RETURNS IN THE FORM OF VIRGA WILL BE LIKELY
DURING THE MORNING HOURS.

IMMEDIATELY FOLLOWING THE PASSAGE OF THE WARM FRONT THE KINEMATIC
FIELDS WILL STRENGTHEN DRAMATICALLY IN THE LOW LEVELS AS A 50-55KT
H8 JET STREAKS IN FROM THE SW. BIGGEST FCST CHALLENGE IS DIAGNOSING
THE POTENTIAL FOR SVR WX DUE TO CONFLICTING SIGNALS. INSTABILITY AND
FORCING ARE DEPICTED DIFFERENTLY BY GFS/WRF WITH THE LATTER
INDICATING NEAR NIL POSSIBILITY OF SVR BUT ALSO NOT THE PREFERRED
SOLN. GFS SHOWS GOOD ASCENT THROUGH A FAIRLY DEEP LAYER MAXING OUT
IN THE H8 TO H6 RANGE...MAINLY DUE TO AGEOSTROPHIC CIRC ASSOC WITH
THE LL JET BUT ALSO SEEMS TO BE OVERFORECASTING INSTABILITY IN ITS
DEPICTION OF ALMOST 1500J/KG BY EVENING....HALF OF THOSE VALUES SEEM
MORE LIKELY. HIGH MID LEVEL LAPSE RATES ARE CONFINING MOST OF
THIS INSTABILITY ALOFT...VERY PRONOUNCED IN THE 0 TO -20C REALM
FAVORING SVR HAIL IN STRONGER UPDRAFTS AS FAR AS PROBABLISTIC SVR
THREAT BREAKDOWN GOES. SVR WIND AND MORESO THE TORNADO THREAT WILL
BE MUCH MORE CONDITIONALLY BASED UPON THE STORMS ABILITY TO BECOME
SFC BASED WHICH GIVEN FCST SOUNDINGS SEEMS RATHER UNLIKELY.
HOPEFULLY THIS WILL STAY THE CASE SINCE SRH VALUES IN THE 0-3KM
AND MORESO THE 0-1KM ARE SO HIGH (APPROX 300 AND 160 M/S
RESPECTIVELY) AND ANY SFC BASED STORM WOULD BE ABLE TO INGEST
THESE VALUES.

[Brent]

Basically they aren't totally sure about a severe weather threat, but as of now the main dynamics aren't that impressive right now.

[HarlequinBoy]

I'm a bit concerned now. My family and some friends are in Oxford, MS at a swim meet and I just got a call saying they were being evacuated down into the lower levels of the complex..


...A TORNADO WARNING REMAINS IN EFFECT UNTIL 715 PM CST FOR LAFAYETTE
COUNTY...

AT 650 PM CST...NATIONAL WEATHER SERVICE DOPPLER RADAR CONTINUED TO
INDICATE A TORNADO. THIS TORNADO WAS LOCATED NEAR OXFORD...MOVING
NORTHEAST AT 60 MPH.

OTHER LOCATIONS IN THE WARNING INCLUDE BUT ARE NOT LIMITED TO
ABBEVILLE AND CAMBRIDGE

[Brent]

OMG!

* AT 658 PM CST...NATIONAL WEATHER SERVICE DOPPLER RADAR INDICATED A
TORNADO 11 MILES SOUTHWEST OF COFFEEVILLE...OR ABOUT NEAR GRENADA...MOVING NORTHEAST AT 95 MPH.

I have NEVER seen one move THAT fast.



AREA FORECAST DISCUSSION…RETRANSMISSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
645 PM CST SAT FEB 24 2007

.UPDATE…MESOSCALE UPDATE.

ALL EYES HERE FOCUSED ON DEWPOINTS. SEEING SURGE OF MOISTURE COMING
UP INTO CENTRAL MS NOW. EXPECTING MOISTURE TONGUE TO SLIDE
EASTWARD…MAYBE NOT AS FAR NORTH…AS ENTIRE UPPER SYSTEM BEGINS TO
LIFT. OF COURSE ALL OTHER DYNAMICS WILL BE IN PLAY. JUST TO SPOUT
SOME EYE POPPING EXPECTED NUMBERS…800+ 0-3 KM HELICITY VALUES…
4 TO 5 0-3 KM EHI…50 KT WINDS AT AROUND 1500 FT. OVERALL THE
QUESTION REMAINS HOW FAR NORTH AND EAST WILL WE BE CAPPED? THE NEXT
QUESTION WILL BE…IS THERE ENOUGH FRONTAL FORCING TO OVERCOME THE
CAP? (MORE THAN LIKELY) THERE IS NO DOUBT THAT EVERYTHING ON THE
SCOPE TONIGHT WILL BE SPINNING. THAT DRAWS THE QUESTION…WITH
DEWPOINTS IN MIND…SURFACE BASED VS. ELEVATED. THAT WILL BE HARD TO
DISCERN TONIGHT. ANOTHER QUESTION IS…WILL THERE BE TOO MUCH SHEAR
ALOFT TO LOP-OFF TOPS…LIMITING GROWTH AND TORNADO THREAT?
(POSSIBLY) EVEN IF…DAMAGING STRAIGHT-LINE WINDS ARE STILL ON THE
TABLE. SOUNDS LIKE I HAVE MORE QUESTIONS THAN ANSWERS. TIMING STILL
LOOKS GOOD ON THE LINE. THIS BROKEN SQUALL LINE SHOULD SHOOT ON
THROUGH. THINGS TO LOOK FOR…ESPECIALLY THE FURTHER SOUTH YOU
GO…ARE TRAINING SUPERCELLS. IF THE NORTHERN PORTION LINE LAYS OVER
(SW/NE ORIENTATION) AREAS COULD SEE A COUPLE OF ROUNDS IN A SHORT
TIME.

SPC Day 1:

THOUGH INSTABILITY DECREASES SUBSTANTIALLY WITH EWD EXTENT INTO ERN
MS/AL…PERSISTENT LOW-LEVEL SLY FLOW SHOULD CONTINUE TO ADVECT
MOISTURE NWD. THIS COMBINED WITH COOLING ALOFT SHOULD ALLOW AT
LEAST WEAK DESTABILIZATION TO OCCUR OVERNIGHT — PARTICULARLY ACROSS
SERN MS/SRN AL/THE WRN FL PANHANDLE. THEREFORE…THOUGH NRN PORTION
OF THE LINE MAY WEAKEN AS IT MOVES ACROSS MIDDLE TN/NRN AL LATER
TONIGHT…SEVERE THREAT WILL LIKELY PERSIST THROUGH THE END OF THE
PERIOD ALONG SRN PORTIONS OF THE LINE AS IT MOVES ACROSS LA/MS/THE
SRN 2/3 OF AL/THE WRN FL PANHANDLE. GIVEN DEGREE OF SHEAR AND
DEWPOINTS IN THE 60S…THREAT FOR TORNADOES — AND POSSIBLY A
SIGNIFICANT ONE — WILL CONTINUE…ALONG WITH POTENTIALLY-DAMAGING
STRAIGHT-LINE WINDS AND HAIL.

[HarlequinBoy]

Me either Brent. The local mets kept saying 90 mph and then 95 mph and I thought they had just made a mistake.

Good news, Oxford seems to be okay. They called and said they were being allowed back up and the sirens had stopped.


On a side not, there's been some signifcant flooding with homes with up to 6 inches of water in them about 5 blocks from here.

[CrazyC83]

95 mph makes you wonder are you sure that is a tornado and not a developing derecho?

[HarlequinBoy]

No, I don't think it's a derecho.

The storm that was moving at 95 mph wasn't part of a line. Well, it was in a line, but the line was broken and the storm had strong rotation on it's southern flank.
