A level 1 was issued for north-western France and the Bay of Biscay mainly for severe wind gusts.
A broad region of weak geopotential and rather cold mid-levels is situated across Europe. To the west, an Atlantic ridge is surrounded by two strong mid-level jet streaks that turn to the south-east when entering Europe. They will affect the British Isles, France, and the Bay of Biscay region on Thursday. At lower levels, rather cold and dry air will limit thunderstorm potential over most places. Moisture gradually increases to the west, but rich low-level moisture is not expected. Best moisture is forecast across the Mediterranean Sea that also overlaps with steeper lapse rates.
