URGENT - IMMEDIATE BROADCAST REQUESTED
TORNADO WATCH NUMBER 353
NWS STORM PREDICTION CENTER NORMAN OK
505 PM CDT SAT JUN 19 2010

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

NORTHERN KANSAS
SOUTHERN NEBRASKA

EFFECTIVE THIS SATURDAY AFTERNOON AND EVENING FROM 505 PM UNTIL
1100 PM CDT.

TORNADOES...HAIL TO 3 INCHES IN DIAMETER...THUNDERSTORM WIND
GUSTS TO 70 MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE
AREAS.

THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 65 STATUTE
MILES NORTH AND SOUTH OF A LINE FROM 35 MILES SOUTH OF MCCOOK
NEBRASKA TO 35 MILES SOUTH SOUTHEAST OF BEATRICE NEBRASKA. FOR A
COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH OUTLINE
UPDATE (WOUS64 KWNS WOU3).

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

OTHER WATCH INFORMATION...CONTINUE...WW 351...WW 352...

DISCUSSION...STORMS ARE BEGINNING TO DEVELOP ALONG A BOUNDARY
LOCATED IN NRN KS...AND SHOULD INCREASE IN COVERAGE THROUGH THE
EVENING. EXTREMELY UNSTABLE AIR MASS AND 40 KT DEEP LAYER SHEAR WILL
BE FAVORABLE FOR INTENSE SUPERCELLS. VERY LARGE HAIL WILL BE THE
MAIN THREAT... THOUGH PRESENCE OF SURFACE BOUNDARY...VERY MOIST
BOUNDARY LAYER AND DEGREE OF INSTABILITY MAY SUPPORT A FEW
TORNADOES.

AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
SURFACE AND ALOFT TO 3 INCHES. EXTREME TURBULENCE AND SURFACE

TREMENDA SUPERCELDA TORNÁDICA con granizos de 4 pulgadas

che che che... .... aca les dejo un videito... bueno. es del 18 ja... bueno. ... me voy a a costar... saludos.!!!!

David, si venis medio "empedado" de la joda de anoche fijate bien al menos los videos , ese video NO es del 18, sino de ayer, 19 de junio, de la supercelda que yo subi esos gráficos de la tarde, fijate que la foto que subi y las imágenes que se ven son iguales, además el video dice 19 de Junio y no 18 , larga el alcohol

Bueno, cambiando de tema y viniendo al día de hoy, TREMENDO! nuevamente, con el frente cálido posicionado en la zona de Nebraska, el cual interactuará con varias ondas cortas y creará un escenario recontra favorables para las superceldas tornádicas a media tarde.

Les dejo los 4 paneles



Y abajo de esto les dejo la discusión para el día de hoy, y noten el TAMAÑO del riesgo moderado en la zona!!! (hoy no dieron vueltas ajajajajaja )

Day 1 convective outlook
National Weather Service Storm Prediction Center Norman OK
0748 am CDT sun Jun 20 2010


Valid 201300z - 211200z


..there is a MDT risk of severe thunderstorms over parts of Nebraska...SD...IA...SW
Minnesota...northern MO...and northwest Illinois...


..there is a slight risk of severe thunderstorms surrounding the MDT risk
area...from the northern and central hi plains to the middle MS valley...


..there is a slight risk of severe thunderstorms over parts of New England and
the middle Atlantic CST...


...
Upper ridge will hold firmly over the Southern Plains through Monday as lead
impulse/jet streak associated with Oregon/Nevada upper low...now over
Utah...shears east/NE into the northern plains this evening...and across the upper MS
valley early Monday. Pattern will therefore remain favorable for numerous
strong to severe storms...with episodic mesoscale convective system development likely
throughout the period.


..cntrl/northern hi plains to middle MS valley today through early Monday...
Clusters of slightly elevated thunderstorms expected to persist through at
least midday over eastern Nebraska and southern South Dakota east-southeast into parts of NE Kansas/Iowa and
MO...supported by weakening warm air advection atop existing convective outflow.
Sufficient MUCAPE and cloud layer shear likely will exist for
sporadic instances of severe hail and perhaps locally damaging wind. Some
regenerative/upstream development also may persist on western fringe of
existing activity...I.E. Over central Nebraska and southern South Dakota.


Approach of Utah upper impulse...associated increase in SW flow
aloft...and surface heating should deepen surface low over eastern Colorado today.
This will serve to strengthen low level east-southeasterly upslope flow north of low
across the central/northern hi plains and adjacent portions of western Nebraska and
the western Dakotas. Coupled with strong surface heating... expect numerous
strong thunderstorms to form by middle to late afternoon over southeast Montana and eastern Wyoming south-southeast
into western South Dakota...western Nebraska and NE Colorado. Other storms may form a bit later
on dry line/Lee trough segments over northern/western Kansas southward into the southern hi
plains.


Potent combination of rich low level moisture beneath deep eml with
40-50 knots deep west-southwesterly shear and increasing ascent with Utah upper
disturbance should support vigorous supercells. These will be
capable of very large hail and a few tornadoes...especially from eastern
Wyoming into adjacent parts of South Dakota...neb...and possibly NE Colorado/northern Kansas late
this afternoon into early tonight.


Aided by a strengthening/broadening low level jet...rich moisture
inflow...ascent with continued east-northeast movement of upper impulse...and low
level uplift along remnant outflow boundaries/warm front...the storms
likely will merge by middle evening into several severe mcss over South Dakota and Nebraska.
The potential will exist for one or two of these clusters to evolve
into a larger scale Bow MCS/derecho...with the system initially
moving mainly east-southeast into southern Minnesota and Iowa...and then more southeastward across southern
WI and northern/central Illinois early Monday.


..nrn rockies/intermountain region...
In eastern quadrant of Oregon upper low...sufficient moisture /pw around .75
in/ should exist to support scattered afternoon/evening storms from western Montana southward
into northwest Wyoming and central/eastern Idaho...given steep low to middle level lapse
rates. With 30-35 knots southwesterly middle level flow and upper diffluence ahead of
low...expect some sustained/organized activity capable of severe
hail/wind. Some of this activity may spread into central Montana this evening.
Farther west...a cluster of regenerative/back-building storms may
persist through tonight/early Monday over central/northern Idaho and western Montana...north
of upper low.


..New England and southeastern New York/New Jersey today...
WV imagery shows a fairly well-defined shortwave impulse...now over
southern Quebec...that should drive diffuse cold front and prefrontal trough
east/southeast off the North Atlantic CST early tonight. Moderate destabilization
likely will occur ahead of front/trough this afternoon...with SBCAPE
increasing to around 1500-2000 j/kg from southern New England into ME.
This should support intensification of existing storms along
trough...and new development along front/trough by early afternoon.
Coupled with 30-35 knots westerly middle level flow and ascent with upper
disturbance...expect a few broken lines/small clusters of multicells
and possibly a few marginal supercells with locally damaging wind/severe
hail through sunset.


..Gulf CST/FL/Carolina coastal pln this afternoon...
Scattered strong diurnal storms are expected from the central/eastern Carolinas
southwestward into Florida today...along Lee trough and sea breeze boundaries.
Somewhat more widely scattered activity may occur along the central/eastern Gulf
CST. Steep low level lapse rates and high precipitable water /around 2 inches/ may
support isolated wet microbursts/locally damaging wind gusts in the very
weakly sheared environment until sunset.


..srn hi plains late this afternoon/early evening...
Isolated severe late afternoon/evening thunderstorms capable of large hail/locally damaging
wind may once again occur along Lee trough/dry line segments in eastern
nm/West Texas...where steep low to middle level lapse rates and moisture will
persist beneath band of enhanced upper flow/weak ascent skirting northwest
side of upper high.
