Wat de wind betreft, dit staat in de tekst voor het zuidelijke deel:
Further South, equally high nighttime temperatures are expected but better mixing will lower the dewpoints to close to 0°C towards the Alpine rim, where a forming barrier jet with 850 hPa winds up to 25 m/s will form overnight. Downward mixing of momentum and evaporative cooling might suffice for isolated severe wind gusts as well when the cold front comes in after midnight. A low-end level 1 was extended Southward for that reason.
