*Monthly outlook* The stratospheric polar vortex will survive all attacks and is coming at us with a vengeance! Late December and January are expected to be milder, with only brief cold episodes!
The stratospheric polar vortex is coming at us with a vengeance! It was under a lot of pressure lately and was fighting for its existence. Being attacked by many pressure and temperatures waves, it survived them all and is now ready to power up. We were monitoring the stratospheric warming event as it was developing. […]

A ‘bombogenesis’ cyclone travels across Iceland – a life-threatening situation with a significant amount of snow (100-200 cm) and hurricane-force winds across the northern half of the country, Dec 10-11th
As we discussed earlier – an active pattern across the North Atlantic – continues this week. A monster cyclone with pressure near or below 940 mbar will develop over Iceland and significantly enhance severe weather threat as an extreme amount of snow, dangerous winds and major snowdrifts develop. The result will be many impassable roads […]
