Schauer und Gewitter am 16.04.2008
Verfasst: Mi 16. Apr 2008, 01:07
Auch heute Mittwoch sind wieder stärkere Schauer und vereinzelt (hoffentlich nicht) Gewitter angesagt. Gute Chancen bestehen wohl in der Nord bzw. Nordostschweiz (wie bereits gestern). Aufgrund einer prognostizierten Windscherung von 20 m/s zwischen Boden und 6km Höhe (sog. DLS - Deep Layer Shear) und eines steilen Temperaturgradienten in den untersten Schichten, könnte das eine oder andere Gewitter rein theoretisch auch etwas stärker ausfallen.

South-west Germany
In the range of an upper trough axis, cold and rather moist low-level air mass will likely destabilize in response to diurnal heating. Showers are forecast given weak CIN and some forcing in the range of the trough axis and underneath the cyclonic flank of the upper jet axis. Showers and thunderstorms are forecast during the day. Vertical wind shear is not expected to be favorable for severe convection, but given at least 20 m/s DLS in the range of the upper jet streak, some thunderstorms may be strong. Given steep low-level lapse rates and rather cold mid-level air mass, marginally severe hail reaching around 2cm in diameter seems the be the most significant threat
