Storm Forecast Valid: Sat 24 Aug 2013 06:00 to Sun 25 Aug 2013 06:00 UTC Issued: Fri 23 Aug 2013 15:46 Forecaster: PISTOTNIK
A level 1 area was issued for parts of W Russia mainly for excessive precipitation.
Level 1 areas were issued for E Spain, parts of France, Switzerland and N Italy for excessive precipitation, severe wind gusts and large hail.
A high pressure system temporarily establishes over Scandinavia, flanked by an upper-level low over Belarus and a second upper-level low that cuts off over Northern France Saturday night. This results in a transient omega-like pattern. Cool air digs southward along the Western flanks of these lows over the Baltic States, Poland and over the British Isles and France, respectively, separated by a thinning warm sector over Central Europe. The Mediterranean region sees a mostly quiescent day in-between, but the nose of a jet streak that extends from Ireland via Southern France towards the Ligurian Sea already promotes a beginning Genoa cyclogenesis and presages more turbulent days again.
