I'm very happy with the GFS 12z. Although its into FI it is very nice to see -10's reaching the SE at 180 rather than 240.

It brings heavy and widespread snow in over the weekend.

I really hope the SE corner , and other lowland eastern and far southern parts get in on the action so that in years to come we can all agree this winter has been better than most!

Are people enjoying the rollercoaster ride? It will be interesting how mild the further reaches of the 12z GFS op get based on the last couple of runs.

Quite a mega easterly a few hundred miles north of the UK in the latter stages of the GFS. Eastern Iceland would feel pretty brisk.

I agree with what Brian is saying. 30 years ago this winter probably would have been up there with some of the best. Even in this modern climate 20/21 has bucked the trend to some degree.

The short stage (pre 192hr) -10°C t850hPa count here on the 12z GFS ensemble set was a noteworthy 28.

The GEM is also living up to its name for some on its op run this evening,

Meanwhile on the GFS the op seems pretty good for cold, better than the 6z.


However an early glance at the ENS shows wide fluctuations at 192hrs. GEFS members will be throwing a great deal of doubt into the mix, and have me concerned more now than in the previous few days

Worthy of mention - GFS actually conjures up a blizzard here next weekend. It won't happen, but it's the first time in many a year I've seen one forecast. Image from xcweather.

It's a fine line to tread though.


Are there examples of charts from "back in the day" that show warm plumes like that in early Feb?

Just dropping in this evening as although I’m more a heatwave person than a snow fan I do enjoy a good beast.

Looking reasonably positive I think. Let’s see what the Euro says. Will it let us have the snow we ordered or ban snow exports and demand we make best reasonable efforts to send it South into the continent while we get some cool dry high pressure?

Spot on. Great set of 12zs so far. The only fly in the ointment is the 12z GEFS. They are all over the  place mid-run with only a small minority showing an Easterly. On the plus side the Op, control and para are fine.
