Well after all the uncertainty of the past week over where the block will
sit, if indeed it wouldd. The models now seem to converge on the idea of a
Scandi block with a substantial deep vortex over eastern Canada. The die is
cast for a battle royal. Cold air will establish over the UK after today
forming a wedge. The deep vortex over Canada will help spawn deep lows in
western Atlantic with extremely cold air pushed SE into the Atlantic slowly
warming. As the lows approach the UK numerous trough disruptions look set to
take place with warm air occluding out and fronts edging into the west,
especially SW. These obviously bring the threat of widespread frontal snow
perhaps turning to rain before the cold comes back after each disruption.
Now, with phase 2 of the SSW expected soon and yet more uncertainty, it
would clearly be imprudenet to suggest how long that regime will continue.
All very interesting, and for meteorologists could be one of the most
fascinating winters for a while. Cold lovers will get satisfaction this
week, folk in the SW and Northern Ireland will be biting their nails "will
it, won't it" LOL.
COME ON ! :-)
