Día desapacible en París, sobre todo por el viento que sopla con rachas sostenidas de 50km/h, del oeste.
Además, cada 2x3 caen chaparrones o xirimiri, aunque también con mini ratos de sol.
No hemos superado los 20ºC,como ha ocurrido en casi toda la fachada atlántica europea. Ahora tenemos 17ºC.

Aqui teneis el satelite, guardarme imagenes por favor que tengo que marcharme

Como suele ser habitual, Austria pillando el grueso de la tormenta.

Hola a todos.
Aquì hoy amanecemos con fresco temperatura min. de 17,4°C.
Por la noche hemos tenido temporal fuerte con lluvia pero durò poco, total 4mm.
Un saludo

Bueno, nadie comentó nada. En el resumen de ESTOFEX podeis ver como han añadido numerosos iconos referentes a granizo grande e incluso un par de tornados.

Ha helado en puntos de Finlandia esta "noche". En Ylivieska -0,9ºC (con una máxima ayer de 12,7ºC), a sólo 56 msm.

Hola buenas dia a todos.
Aquì en Cesate hoy amanecemos con fresco, temperatura miniuma de 18,5°C y cielo un poco nuboso.

Dublín vuelve a ser la capital más fresca en Europa, con lluvia y sólo 13ºC entre las 2 y las 4 de la tarde.

Hola a todos.
Aquì en Cesate(Milàn) amanecemos con fresco temperatura minima 18,4°C y cielo sin nubes.

Hola buenas dia a todos.
Aquì en cesate (Milàn) amanecemos con vielo nuboso  y temperatura minime de 20,5°C.
Por el fin de semana esperamos pertubarciòn frìa con temporales y lluvia fuerte y viento fuerte.

Hoy las mínimas no han sido, en conjunto, tan bajas como otros días en Suecia, pero ha helado en una estación oficial del instituto sueco, con -1,2ºC, estación situada a 577 metros de altura. No sé si estas heladas suecas se pueden considerar las últimas de la temporada, o las primeras del año. Rarezas del clima sueco.

Temperaturas europeas hoy  a las 9 de la tarde. A destacar los valores anormalmente bajos en ciudades del norte de España para esas horas.

Por delante otro dia extremadamente tormentoso...



SYNOPSIS

*** Active severe weather day expected over the N Mediterranean and portions of east-central Europe ***

Deep and quite intense, quasi-stationary upper long-wave trough is covering the western parts of Europe, slowly beginning to evolve into an upper cut-off cyclone over the Alpine regions late in the period. Several smaller-scale vorticity maxima are imbedded in the strong SSWLY upper flow at the eastern side of the large-scale trough. A well-defined low-level baroclinic zone is stretching from SW Iberia diagonally across Europe via the Baltics into NW Russia at the beginning of the forecast period ... and will become more north-south oriented by the end of the period. At the surface, two high pressure areas over the E Atlantic/W Europe and over E Europe/W Russia are surrounding a weak low-pressure region aligned with the main low-level front. The air mass immediately to the E of this frontal zone is exhibiting rather strong low-level moisture variations, so that profiles range from Miller-type I soundings (E Spain) to inverted-V (N Balkans). GFS predicts mean 0-1 km mixing ratios in excess of 10 g/kg on the immediate warm side of the front in the afternoon and evening hours.

DISCUSSION

... N Italy ... extreme S Austria ... extreme NW Balkans ...

00Z ascents from N Italy and the N Balkans suggest that depth of low-level moisture is rather low, though continued evapotranspiration along with mesoscale convergence may at least locally lead to appreciable depths of boundary-layer moisture. Still, some variability in LCL height as well as CAPE strength might exist today. Where moisture has accumulated, CAPE may increase to 2000 J/kg.

Impressive deep-layer shear is present over the region, exceeding 25 m/s throughout the period. LLS is initially expected to be rather weak, but to increase over NE Italy and the extreme NW Balkans in the late evening hours, exceeding 10 m/s per GFS.

An upper vort max is currently crossing the region, but WV imagery suggests that a dry slot is overspreadign the unstable air over N Italy, increasing confidence that unimpeded insolation will be realized over N Italy during the next few hours. QG-forcing for ascent should increase again in the late afternoon and evening hours upon approach of the next vort max.

Convective initiation may be delayed somewhat in the wake of the first vort max, aiding in the buil-up of instability and suppressing widespread storm development. Isolated storms should initiate in the afternoon hours, however, given sustained low-level warm advection and suspected mesoscale regions of LL convergence associated with orography or mesoscale boundaries laid out by earlier convection. Coverage should increase later in the day as large-scale forcing for ascent overspreads the area.

The cells that form should immediately become supercellular, main threat being large hail and damaging winds. It seems that the hail threat will be maximized where low-level moisture will be deepest, and very large hail, well in excess of 5 cm in diameter, may occur. As coverage increases, storms may merge into linear segments/bow echoes.
In the evening hours, it seems that rich low-level moisture/strong CAPE and quite favorable shear profiles will coincide, which suggestss that an additional threat for tornadoes will exist. Anticipated storm coverage and degree of severity necessitate a level-three threat.

... N Czech Republic ... NW Slovakia ... Poland ...

Steep mid-level lapse rates and rich low-level moisture should persist over Poland, and thunderstorms should develop in association with a frontal wave, propagating northeastwards along the front during the period.

CAPE should rise to about 1500 J/kg during the afternoon hours, while DLS should be in the 15 to 20 m/s range. Most striking is the simulated LLS which increases to 15 m/s in the afternoon and evening hours. Any storm developing in this environment will likely become supercellular ... with a distinct threat for tornadoes - apart from large hail and damaging straight-line wind gusts.
