A spell of severe weather is expected to affect parts of France overnight and through Wednesday morning as an area of low pressure makes its way in from the Bay of Biscay.
The area of low pressure highlighted in the satellite image above is expected to deepen and develop before affecting parts of France this evening and overnight.
Pressure chart for 1 am Wednesday 13 August
Forecast rainfall for 1 am Wednesday 13 August
This brings the risk of severe thunderstorms across western, then southern France overnight and during Wednesday morning. This will bring the potential for flash flooding and will give squally winds, with disruption to local infrastructure and to holiday makers in the region. Very strong winds and high seas are also likely for a time overnight along the western coastline of France. Meteo France currently has severe weather warnings in force.
This area of wind and rain should then move quickly across Switzerland and southern Germany during Wednesday afternoon.

Reblogged this on the WeatherAction Blog and commented:
France seems to have taken a bit of a battering this year.
Sorry, this can’t be true – according to your guru the “pressure pattern has recovered to Weather Action forecast” with high pressure over France. I don’t think that bothers you though? Shame.
I’ve put together some overnight rainfall totals for central Europe on my blog if anuone is interested:
