Superwaardes volgende week donderdag zware complexen uit frankrijk mogelijk beetje Lt maar de trend gaat naar nog warmer weer ook de pluim laat dit zien

there can be only one
Kaart van estofex staat al in het forum hier de tekst:
A level 1 and level 2 were issued for North-Central Europe mainly for excessive precipitation and to a lesser extent for severe wind gusts.
SYNOPSIS
A complex upper-level low still governs the weather over much of Europe. Its individual centers move from the Channel into Southern France, from Bosnia into Western Romania and from Lithuania into Northern Poland, respectively. The former two also induce weak surface cyclogeneses ahead of their paths in response to travelling vorticity maxima aloft.
While cool air is present in the range of these upper-level low centers, very warm air from Turkey spreads over the Black Sea, the Ukraine and Belarus. A moderate mid-level jet surrounds the upper-level low to the South and stretches from Southern Itay across the Eastern Mediterranean to the Black Sea.
Anticyclonic influence dominates from Iberia across the British Isles into Scandinavia.
. Central Europe ...
Setup is very similar to the day before in the enclave of warm and moist air that is centered over the Netherlands and much of Germany. CAPE up to 1000 J/kg will quickly build again in response to diurnal heating, and widespread thunderstorms will form in the afternoon and evening. Weak vertical wind shear will mostly preclude a better organization, but upscale growth into numerous large clusters is likely. With very slow motion and precipitable water in excess of 30 mm, another round of quite numerous flash floods is suspected. Cold pool formation in large clusters may also result in a few swaths of severe wind gusts.
Highest coverage of storms can be expected along the main convergence zone which runs from the Central Netherlands across North-Central Germany into Bohemia and the bordering region between Austria and Slovakia, only very slowly moving towards the Southwest. Especially along this convergence, also one or two non-mesocyclonic tornadoes may spin up.
The advection of drier and cooler air will gradually start to quench activity from the Northeast towards evening.

Noordhorn(GR) strak blauwe lucht, wel een beetje 'melkachtig' en temperatuur die nu al 25 graden aanwijst! Luchtvochtigheid is momenteel 73% en er staat matige wind(3-4 bft.). Echt benauwd is het niet mede door de wind, ik denk dat we net aan de goede kant zitten van Nederland, net als gisteren zullen de buien ten zuiden van ons ontstaan. Heb vannacht nog richting Apeldoorn/Arnhem gekeken en ik kon vanaf hier de CB oplichten om de seconde, prachtig gezicht!
Weekend gebaseerd in Drenthe & doordeweeks werkzaam in Antwerpen.
