recien salidito del canal de youtube de reed, increible lo rapido que se mueven los sistemas alla

Otro videito!

Sabes Lisan que recien me levanto y me quede asombrado de ese video y los múltiples tornados que estuvieron capturando, que seca es esa zona de Minessota, ideal para cazar te digo, y que impresionante como los tornaditos rotaban alrededor del mesociclón, debe ser una locura analizar esa tormenta en detalle, debe de haber máximos de rotación por todos lados

che matute... vos decis que esos multiples vortices se deben a la seca de la zona????.... por eso aparecen?

si yo entendi bien... esos no es asi... las multiples vortices se deben a la severidad del tornado!!!!!!!! creo

Tornado en Wadena .... Daños!!!

nooooooooooooooooooo, ajajajajaaja, cuando dije ideal es porque al ser bastante seca ni arboles tenes, y tenes un horizonte espectacular que te permite ver casi todo, a eso me refería, ajajajaja

Nooo, el aire seco en niveles bajos le juega en contra siempre a los tornados, porque hace que haya bases elevadas!

Riesgo MODERADO (tarde amanecimos.....)

Day 1 convective outlook
National Weather Service Storm Prediction Center Norman OK
0759 am CDT Friday Jun 18 2010


Valid 181300z - 191200z


..there is a MDT risk of severe thunderstorms over parts of Iowa...MO...and
Illinois...


..there is a slight risk of severe thunderstorms surrounding the MDT risk area
from the lower MO and middle MS valleys into the upper Great Lakes...


...
Active pattern will persist this period. Southern mb upper low will
continue east-northeast into southern ont as broad upstream trough/low lingers over
the west and Flat Ridge persists over the S central/southeastern U.S. In wake
of shortwave impulse associated with mb system now moving northern
Minnesota...satellite and model data suggest that impulse now over the western
Dakotas will sweep east-northeast later today...reaching eastern Minnesota/northern WI by early
evening.


At the surface...lead cold front associated with mb low should continue
NE across the upper Great Lakes and weaken as a new cold front evolves
today over the eastern Dakotas/MN. The new front should accelerate east/southeast
across the northern half of the plains and upper MS valley tonight/early
Sat...serving as a focus for storms. Farther S...outflow boundary
from overnight mesoscale convective system in the middle/upper MS valley...and remnant warm frontal
segment will help initiate storms over parts of the lower MO valley/middle
MS valleys.


..upr MS valley/upper Great Lakes through late tonight...
Strong wind field with vertical shear favorable for supercells will
develop over WI/Upper Michigan later today as Dakotas upper impulse approaches
region. Sufficient low level destabilization should occur ahead of
developing cold front to support late day storm development from NE
Iowa northeastward through central WI into Upper Michigan. Strength of wind field /40-50
kts at 700 mb....with 50-60 kts at 500 mb/ suggests a risk for
strong tornadoes given likely enlarged low-level hodographs. In
addition...setup eventually should support broken line segments or
qlcs structures...with high wind from embedded supercells/bows. The
threat should diminish later tonight as the storms/forcing outrun
low level instability axis in lower Michigan.


..lwr MO valley to middle MS valley through late tonight...
Mesoscale convective system now developing over eastern Nebraska may persist and possibly
strengthen...moving east-southeastward through midday as surface heating destabilizes
region partially affected by yesterday's storms. Outflow boundary
from this activity and/or existing outflow boundary/warm front
should serve as foci for additional...intense storm development this
afternoon as SBCAPE increases to around 4000 j/kg over parts of Iowa/northern
MO/NE Kansas. Although deep shear will be modest relative to that
farther north...given degree of instability on edge of eml and rich
moisture availability /sfc dewpoints around 70 f/ will be ample for
sustained storms and a few supercells before activity congeals into
one or more large clusters. Embedded forward-propagating segments
will be capable of damaging wind/hail east/southeast into Illinois. Some very large
hail could occur over western portions of this region during the early
stages of storm development.

increibles los videos!!, me encanta ese tipo de tornado que antes de formarse completamente forma pequeños toranditos que terminan uniendose (muy tecnico lo mio jaja) .. excelente el aporte lisan

Impresionante el video Lisan !
