...Spain and France...
A solid 20 m/s or higher 0-6 km shear region develops east of the shortwave trough, in the same area as the large CAPE. The 00Z GFS predicts capping until about 15Z. Supercells are likely to be the mode over (north)eastern Spain, with clustering likely in northern Spain and southwestern France, where GFS and various WRF models agree on a large MCS during the evening and night. These storms are capable of producing very large hail, as well as severe convective wind gusts. Furthermore, excessive rain sums can result, mostly along the south slopes of the Pyrenees where upslope moist winds provide fuel for long-lasting storms.
No lo tengo tan claro, polvo en concentraciones medias tirando a altas, salvo al final de la tarde:
Los modelos mesoscalares apuntan a una elevadísima cizalladura en Navarra, las SP que se formen se quedarán en el sitio, las células que logren formarse, se desplazarán muy rápido.
