Daar komt bij dat volgens ESTOFEX de squall-line zich steeds beter zal gaan organiseren boven de Noordzee:
The front should become defined as a rainband as low-level convergence increases during the morning and the afternoon when it tracks southeastward across Wales and England. The strong background wind field of 30-35 m/s at 850 mb suggests that severe gusts should gradually become an increasing risk. Some very severe gusts of over 32 m/s may occur especially while crossing the North Sea and affecting the Benelux countries.
Convection allowing models suggest that some mesovortices may develop along the line in particular when it moves inland across the Benelux, northern France and western Germany where it encounters strongly helical low-level flow (>400 m2/s2 storm-relative helicity in the 0-1 km layer) This would suggest that an enhanced risk of very severe gusts > 32 to extend inland, as well as a risk of tornadoes.
