Greenland low temperature records to be broken?

Hi,


Greenland has never been colder at this time of year perhaps in recorded history and in a reversal of a trend that has been going on for the last two decades at least, right now, Greenland is extraordinarily cold for the time of year. -60, -65s being recorded and records may be broken in the next week or so as the landmass continues to see deep cold pooling in the region.

This will effect our weather for the winter but how is open to speculation. Be interesting to see if officially records get broken:)

WOW! If those NW Winds continue, then it's gonna get mega cold here with loads of snow... wouldn't last more than a few days, but bhoy, if a cold front comes in from the NW with that air behind, then 2 foot of snow over the majority of Ireland would be a realistic expectation IMHO. That type of air spawns "white-out" showers, where up to 2 inches of snow gets dumped in 15 minutes, as per 29th Dec 2000 and Feb 1994.

SSTs are higher in the North atlantic between us and Greenland and which means two things if a NWly from a Greenland origin where to happen.
It can be condusive to the formation of Polar Lows or a cold pool of air is warmed enough over a warmer ocean which takes the real cold from it and leaves us in a cold but not bitter biting cold air mass.

Therefore SSTs (sea surface temps) can be in favor or against on how cold it would get and how much snow where to fall if at all at low lying regions.

Is that you in disguise Weathercheck?
It would be great to have a snowfall to remember, just like years ago.
It'll be interesting to see what effect, if any this will have on our winter...

Nope! LOL! Those were two exciting times though!

It's probably a good sign for the winter for two reasons.
1. westerly snow or even south westerly snow is more common recently as Deeply cold Northerlies plunge down the Atlantic and then curl in from the west or south west to us.

We get snowy south westerlies or westerlies as a result due to the bitter origin of the air.That scenario gave the south west and west a very white Xmas a few years ago.Bitter cold Greenland sourced air is conducive to making showers and has an especially long sea track to make if you will the mother of all "lake effect" snow scenario's.
That usually means a dry East coast though ie not much snow there.

2. The deep cold over Greenland is also conducive to building high pressure and the famed northern block which,starting this early could see us with an Easterly in mid to late december or january(rather than late feb/march as in the last 2 years) and that would/should mean snowy conditions in the East but a dryer than normal west.

Hope Dublin gets a good sprinkling at some stage, can't wait to see the school run 4x4's panicking
