Severe Weather Outlooks FAQ

SYNOPSIS

An upper ridge is centered over N Atlantic and W Europe, while a deep trough moves across NE Europe. An associated short-wave trough moves across Belarus towards Russia. Another short-wave trough continues south across the Balkan peninsula and Mediterranean. A large upper low intensifies over Morocco and Algeria. A new deep trough develops over Greenland and results in tightening pressure gradient towards Iceland.
