SYNOPSIS
Low pressure areas at the surface is found over Spain and develops over the English Channel and France. A trough extends eastward over the Alps to Ukraine. Blocking high pressure is present over Scandinavia and Russia. A strong easterly flow develops north of the French low and the trough.
There are three important shortwave troughs around the main mid level low. The most dynamics are associated with the trough over the southern UK where an occluded front will linger for a while. The other two affect southern Iberian Peninsula and central Europe, Poland in particular.
