Chilly UK? Current Air Mass Traced Back To Canadian Arctic, NAO Really Tanking!

We have late season arctic air draped across Ireland and the UK today, feeling distinctly cool, particularly if exposed to that stiff westerly breeze. This air mass can be traced all the way back to the Canadian Arctic where originally it supported temps of -10 to -30C, thankfully crossing 3,000 miles of Atlantic Ocean and SST’s at 6-10C SE of Greenland, it’s warmed significantly.

However, when adding ocean warmth to a cold airmass at this time of year, you get a lot of turbulent, convective shower activity and that will be the story throughout today and the next couple of days.

Really you can expect sun and showers across many areas not just today where they’ll contain hail, thunder, lightning, sleet as well as snow, all dependant upon elevation. Winds will be particularly gusty beneath these showers and can turn colder by several degrees then rise after it passes.

The next 24 hours will see winds over UK veer northerly.

There’s a void (high pressure) in our weather late Thursday into Friday which may support frost if skies are clear ahead of another approaching CF.

It gets somewhat more interesting through the weekend (meteorologically speaking) as we get an enormous height rise from central Atlantic up into Greenland while a large and cold trough spins lowsover Ireland and the UK. This will keep us unsettled and cool.

According to the GFS, that monster high leans eastward across Iceland, forcing the mean low SW’ward early next week.

This essentially pushes the disturbed weather to our SW and we get into a chilly NE air flow dragging some pretty cold air in off Norway.
