Pero que buenas imagenes!!

Esas en 3D me dan la sensación de que la celda tiene forma de corazón

Dejen, dejen..ya me voy solito para mi habitación en el Borda

[matute_bow]

AJAJAJAJAJAJAJA, MAX, AJAJAJAJAJAJAJ

Si, en forma de corazón tienen los granizos que caen abajo

[arielmich]

Miren lo que es la imagen de radar... Es una encrucijada esto, parece un laberinto sin salida. Nunca vi tantas cajas rojas y ahora tambien el triangulo de mas Bermudas parece que se mudo a la zona!

[matute_bow]

No voy a agregar mas que esta discusión actual de meso-escala en la zona, sinceramente METE MIEDO

EXTREMO TIEMPO SEVERO EN USA, CAPITULO 3 (la batalla final!)

MESOSCALE DISCUSSION 0620
NWS STORM PREDICTION CENTER NORMAN OK
1045 AM CDT WED APR 27 2011

AREAS AFFECTED...FAR EASTERN LA AND NORTHERN/CENTRAL PORTIONS OF MS
INTO AL

CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY

VALID 271545Z - 271715Z

A LONG LEAD-TIME/LONG DURATION PARTICULARLY DANGEROUS /PDS/ TORNADO
WATCH WILL LIKELY BE ISSUED SOON...MOST CERTAIN ACROSS
NORTHERN/CENTRAL PORTIONS OF MS.

VISIBLE SATELLITE/SURFACE OBSERVATIONAL TRENDS IMPLY RELATIVELY
QUICK AIRMASS RECOVERY/DESTABILIZATION IS OCCURRING FROM LA INTO
MS/AL THROUGH MID/LATE MORNING. THIS IS THE CASE NOT ONLY FOR IN THE
VICINITY OF EARLY MORNING WEST-EAST OUTFLOW ACROSS MS/AL...WHERE
SURFACE TEMPERATURES/DEWPOINTS HAVE EACH INCREASED 8-12F OVER THE
PAST 2 HR...BUT ALSO IN THE WAKE OF AN APPARENT WAVE-LIKE FEATURE
SPREADING EASTWARD CROSS CENTRAL PORTIONS OF MS/LA AS A CU FIELD
OTHERWISE CONTINUES TO INCREASE/MATURE ACROSS NORTHEAST LA.

AIDED BY STRONG AMPLIFICATION/INTENSIFICATION OF AN INCREASINGLY
NEGATIVE TILT SHORTWAVE TROUGH/ASSOCIATED JET STREAK LATER TODAY...A
VOLATILE SCENARIO IS EXPECTED TO UNFOLD THROUGH THE AFTERNOON.
CONVECTIVE INITIATION OF VIGOROUS CONVECTION BY EARLY/MID AFTERNOON
IS WELL SUPPORTED BY EXPERIMENTAL GUIDANCE SUCH AS SEVERAL RECENT
HRRR RUNS AND THE 12Z WRF-NMM. SHORT TERM FORECAST SOUNDINGS FROM
GUIDANCE SUCH AS THE RUC/12Z NAM...ACCENTUATED BY VERY LONG/STRONGLY
CURVED LOW LEVEL HODOGRAPHS...SUPPORT THE NOTION OF SUPERCELLS
CAPABLE OF STRONG/POTENTIALLY VIOLENT TORNADOES THIS AFTERNOON/EARLY
EVENING ESPECIALLY ACROSS THE HIGH RISK AREA.

Me duro poco la discusión de mesoescala, ya mandaron un tornado watch, pero que Matias, un que?

UN TREMENDO TORNADO WATCH EN PDS!, con una discusión T-R-E-M-E-N-D-A, jamás leí algo asi, ajajajaja, esa zona sinceramente es una bomba de tiempo!!


URGENT - IMMEDIATE BROADCAST REQUESTED
TORNADO WATCH NUMBER 232
NWS STORM PREDICTION CENTER NORMAN OK
1105 AM CDT WED APR 27 2011

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.

Algunos sondeítos de la mañana de hoy en la zona. Impresionante el perfil de vientos, ¿cuándo se ven perfiles así por acá?, en la noche de los tornados bonaerenses del 93 nada más. Impresionante aparte tener lifted o showalter de -7 en las primeras horas de la mañana, ¿qué queda para la tarde?

[maxi_rosario_eche21]

El LLJ del sondeo de Shreveport es monstruoso! Por que esta todo saturado de 800 para abajo? estaba con lluvia?
