Impresionante!!!
Miren la discusión de riesgos de tiempo severo y tormentas hoy en la zona. Traten de leer detenidamente y acuerdense de lo que discutíamos nosotros hace 15 días atrás, con el tema de la humedad / inversiones / etc etc, y miren como ellos también presentan los mismos problemas para determinar bien las cosas!, esta muy bueno, se aprende mucho!
Les copio la discusión y les dejo la página nuevamente, así miran también como siguen los eventos de nieve fuerte actuales en la discusión de mesoescala, debajo de la que les estoy haciendo referencia. Es impresionante como miran y analizan todo, COMO DEBE SER, para llegar a los resultados que llegan, y NO SOY EXTRATERRESTRES, SON UNICAMENTE METEOROLOGOS, quizás hasta con menos grado de enseñanza que nosotros (ya que la teoría de la carrera en Argentina es muy amplia y fuerte), pero sin embargo lo aplican todo como debe ser!, ojalá alguna día nosotros podamos aunque sea poder hacer estas cosas PERO DESDE EL ORGANISMO OFICIAL (me agarra escalofrío de pensar que ya tienen un formato de alerta, aca me refiero, para todos los eventos y le hacen copy past
)

Day 1 convective outlook
National Weather Service Storm Prediction Center Norman OK
0629 am CST Tuesday Dec 08 2009
Valid 081300z - 091200z
..there is a slight risk of severe thunderstorms across the lower MS valley/middle
south into central Gulf Coast states...
..OH valley into the central Gulf Coast...
Models and overnight observational data consistent in lifting
significant middle/upper level trough and associated wind fields across
a large portion of the southern/central U.S. Through the period. Surface
low will become better defined over the Southern Plains and lift across
the lower MO River Valley by late today...before undergoing
significant deepening into Lake Michigan and vicinity overnight. Broad
warm sector will attempt to become defined over a large area from
the central Gulf Coast states into the Ohio Valley by this
evening...although degree of boundary layer destabilization beneath
strong warming in the 850 mb-700 mb layer remains uncertain across the warm
sector. Regardless...shear will become substantial over the whole
region with significant values of low level shear/helicity which
poses a threat of very organized moist convection including
low-topped supercells/lines.
Early morning surface analysis indicates only a small area along the
la coast experiencing marine influx...with broad area of leading
deep moist convection inhibiting northward return of Gulf moisture early
today. This activity will likely continue east-northeastward and weaken through
the morning and begin to allow erosion of coastal front as
strengthening south-southeasterly low level winds begin mixing to the surface.
This should support northward influx of at least middle 60f surface dew
points across the lower MS River Valley...with near 50f dew points
developing across the middle south late today. This should support a
relatively Low-Cape but high shear environment with substantial
severe threat dependent upon quality of surface-based instability
today. Forecast soundings support general erosion of cap by late
today coincident with general veering low level wind fields as
system deepens well to the northwest.
Expect increase in thunderstorms...some rotating...through the afternoon
along the lower MS River Valley with diurnal heating.
Low-topped...fast moving supercells and small lines should evolve
from parts of the middle south into the lower MS River Valley which
will spread east-northeastward overnight across the central Gulf Coast states.
Wind damage and tornado threat will be persistent with these
storms...although questions about boundary layer destabilization
tend to lower confidence/coverage forecasts at this time. Elevated
supercells may be capable of hail as middle level lapse rates steepen
northward into the Ohio Valley...with additional threat of isolated
strong/damaging winds from low-topped...strongly-forced line of
moist convection ahead of cold front overnight.
..coastal Carolinas into southeastern Virginia...
Overall transition to south-southwesterly flow from the southern/central Appalachians
eastward during latter half of period should allow modified boundary
layer to overspread this area overnight. While the greater air mass
destabilization is forecast to remain confined to the coasts...it
does appear that sufficient instability may be present to support
the development of isolated/scattered nocturnal storms within
strengthening warm air advection regime...especially in vicinity of and east of coastal
front. Although low and deep layer shear will become quite
strong...overall instability remains weak at best with near moist
adiabatic lapse rates evident on forecast soundings. Expect a few
rotating updrafts will evolve overnight with at least low
probability threats of strong/damaging winds and possibly a brief
tornado. However...questionable instability may tend to limit
overall severe threat.
