Areas affected...Northern Arkansas...southern Missouri...far western
Tennessee and Kentucky

Concerning...Severe potential...Watch unlikely

Valid 061643Z - 061915Z

Probability of Watch Issuance...20 percent

SUMMARY...A smattering of thunderstorms today will have the
capability of producing marginally severe hail.

DISCUSSION...A small cluster of thunderstorms persists across
northeast AR in a zone of modest instability and supported by an
elevated warm front. Flow aloft is strong out of the west, resulting
in favorably long hodographs for sustained cells. These cells have
mainly shown indications of hail less than 1.00" this morning.

Behind this activity, satellite imagery shows new elevated
development across far northern AR into southwest MO, with lighting
recently detected. Models suggest increasing lift from warm
advection across this area today with backed 850 mb flow. In
addition, temperatures aloft are cooler with northward extent which
will aid destabilization as low-level warm advection continues. The
result should be an additional rash of strong storms with a few
containing hail up to 1.00".

Alberto, por qué no haces lo mismo para Europa, África, Asia y Oceanía? Ya que subis cada maldita tormenta que hay en EEUU, podrías hacerlo para todo el mundo, y también las que están en los ocános ya que estamos.

Como era de esperarse, octubre récord en Nueva York y alrededores para la mayoría de las estaciones. Central Park tuvo casi calcada la misma temperatura media que OCBA en este mes. De locos!

Creo que lo que más me sorprende es lo alto del récord anterior en 2007. Pensé que habrían pulverizado el récord anterior.

Y para los próximos días se les viene un frío notable. Hasta -4 grados Celsius en NYC y cerca de -10 en el norte de Maine la mañana del sábado según WeatherNation.

Regresa el tiempo severo en algunas zonas del sur y medio oriente de los Estados Unidos. Viento y granizo, los riesgos más importantes. El pasaje de un intenso frente frío y su interacción con una masa de aire cálida y húmeda proveniente del Golfo van a estar formando chaparrones y tormentas en las próximas horas.

Day 1 Convective Outlook RESENT 1
NWS Storm Prediction Center Norman OK
1022 AM CST Sat Nov 18 2017

Valid 181630Z - 191200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PARTS OF THE
OHIO AND TENNESSEE VALLEYS...

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PARTS OF
THE OHIO AND TENNESSEE VALLEYS...

...SUMMARY...
Thunderstorms capable of severe wind gusts, marginal hail, or a
brief tornado will be possible this afternoon across parts of the
Ohio and Tennessee Valley regions.

...OH/TN Valley Region...
Water vapor imagery shows a vigorous upper trough moving rapidly
eastward across the Central Plains. Large scale forcing ahead of
this feature is overspreading the mid MS and lower OH valleys, and
should result in scattered afternoon thunderstorms. Storms will be
focused along a cold front - initially over central/southern IL and
southeast MO. This activity will spread eastward through the
evening hours into parts of IN/KY/TN. Wind fields are very strong,
and are supportive of organized storms with bowing and supercell
structures. However, low-level moisture and CAPE are quite limited
today with dewpoints only in the 50s to lower 60s, and MUCAPE values
below 1000 J/kg. Considerable cloud cover and slightly veered
low-level winds are also negatives for a more robust severe event.
Nevertheless, the initial storms over IL/MO and western KY/TN may
produce large hail, with the risk of damaging winds increasing
through the event farther east. A tornado or two is also possible
in early supercells, and along the QLCS(Quasi Linear Convective System, o Sistema Convectivo Cuasi Lineal) later today.

Mesoscale Discussion 1768
NWS Storm Prediction Center Norman OK
0529 AM CST Sat Nov 18 2017

Areas affected...Parts of northeast MO into central IL and central
IN

Concerning...Severe potential...Watch unlikely

Valid 181129Z - 181400Z

Probability of Watch Issuance...20 percent

SUMMARY...The potential for storms producing hail will increase some
this morning across northeast Missouri through central Illinois into
central and perhaps northern Indiana. Most of the hail should be
sub-severe, though a marginal risk does exist for a couple to exceed
1 inch in diameter.

DISCUSSION...Trends in early morning radar imagery indicated an
increase in thunderstorm development across west-central into
central IL near and just north of a warm front that was analyzed at
11Z extending to the east-northeast from a surface low in central MO
through central IL to central IN. Forcing attendant to
strengthening deep-layer ascent with the approach of a progressive
trough moving east from the Plains today should promote a further
increase in thunderstorm development near the warm front, as the
surface low tracks east-northeast along this boundary. Additional
forcing for ascent will be attendant to the exit region of a strong
(110-140 kt) 250-mb jet nosing into to the mid MS and lower OH
Valleys this morning to the afternoon. 10Z RAP soundings are in
good agreement with surface temperatures/dewpoints near the warm
front, and the forecast suggests the stable layer should persist
such that storms remain rooted in the 900-850 mb layer. Steep
midlevel lapse rates atop the shallow inversion combined with
sufficient bulk shear suggest stronger storms could produce isolated
hail, with a couple exceeding 1 inch in diameter.

Areas affected...Northeast AR to Central IN

Concerning...Severe potential...Watch likely

Valid 181624Z - 181830Z

Probability of Watch Issuance...80 percent

SUMMARY...Severe threat will increase into the early afternoon hours
ahead of progressive cold front. Severe thunderstorm watch will be
issued by 18z to account for this potential.

DISCUSSION...Strong 12hr mid-level height falls will overspread the
OH Valley and mid-south region this afternoon ahead of a progressive
cold front. Large-scale forcing for ascent will be focused across
this region but environmental capping is expected to restrict
appreciable pre-frontal convection, except for the warm advection
corridor across the OH Valley. Latest visible satellite imagery
suggests strongest boundary-layer heating is noted just ahead of the
front from central AR into southwest IL. This is supported in OA
fields where surface-3km lapse rates are now on the order of 6.5
C/km where partial sunshine is observed. Given the strong capping
observed, thunderstorms are expected to initiate along the surging
cold front. Latest radar data supports this scenario with convection
gradually increasing along the wind shift from east-central IL into
southeast MO where lightning is currently observed. Damaging wind
threat will increase with frontal convection as it matures,
potentially encouraging strong environmental winds to mix to the
surface with stronger downdrafts.

URGENT - IMMEDIATE BROADCAST REQUESTED
Severe Thunderstorm Watch Number 516
NWS Storm Prediction Center Norman OK
1205 PM EST Sat Nov 18 2017

The NWS Storm Prediction Center has issued a

* Severe Thunderstorm Watch for portions of
Southern Illinois
Central and Southern Indiana
Western Kentucky
Southeast Missouri
Western Ohio

* Effective this Saturday afternoon and evening from 1205 PM
until 600 PM EST.

* Primary threats include...
Widespread damaging wind gusts to 70 mph likely
Isolated large hail events to 1.5 inches in diameter possible
A tornado or two possible

SUMMARY...A fast-moving line of thunderstorms will sweep across the
watch area this afternoon, posing a risk of locally damaging wind
gusts. Some risk of hail and a tornado or two also exists.

The severe thunderstorm watch area is approximately along and 80
statute miles east and west of a line from 45 miles north northeast
of Muncie IN to 45 miles south of Cape Girardeau MO. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU6).

PRECAUTIONARY/PREPAREDNESS ACTIONS...

REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for 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. Severe thunderstorms can and occasionally do produce
tornadoes.

&&

AVIATION...A few severe thunderstorms with hail surface and aloft to
1.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A
few cumulonimbi with maximum tops to 400. Mean storm motion vector
26040.
