Model output discussion - after the beast, what next?
ScottishSnowStorm replied to Paul's topic in Forecast Model Discussion
GEFS 0z has more members than the 18z going for sub -10 uppers at 850hpa in fife scotland so a step forward on there and ECM looking better Hopefully we can keep seeing upgrades and the block getting into Greenland and not collapsing as there is plenty cold uppers to tap into over russia by this point -

UKMO 144hr 850 temp chart we see the 0c line move well away and lots of scope for prolonging the cold spell further- 1,198 replies

The low definitely looks further south on the 12z Cold air looks further south as well and the cold pool looks to be just a little stronger- 1,198 replies

ICON 12z has the 0c temp line a little further south over northern spain than the 6z so hopefully an early good sign- 1,198 replies

Model output discussion - here comes the beast!
ScottishSnowStorm replied to Paul's topic in Forecast Model Discussion
Hopefully this just turns out to be the same as the easterly is going too far south incident we had and over the next 24hrs things get back to how they were looking earlier on -

ScottishSnowStorm replied to Paul's topic in Forecast Model Discussion
Is what we are seeing in the output now because the whole of the PV has been shunted into russia and placing too much pressure on the blocking to allow any easterly winds to exert thereselves on our side of the hemisphere? -

Strange how it can be the milder option down south but one of the colder here in scotland till nearer the end of the run how often can that happen? -

The 18z ensembles don't even look to keep the cold here in the scottish central belt -

The UKMO fax charts yesterdays 12z 96hrs todays 0z 84hrs and todays 12z 72hrs all for this tuesday and the high over scandinavia is being upgraded every chart and so is the bank of sub 510 dam air spreading through europe -

ECM snowfall charts from just the operational (master) and the control at day 10 and from the looks of the control it takes the low into france so a big change just between them and hopefully the control is right with this one -

I wonder what the spread is in the ens from cold v warm perspective maybe 25-13? -
Model output discussion - here comes the beast!
ScottishSnowStorm replied to Paul's topic in Forecast Model Discussion
More spread at the end of run compared to the 0z and mean a little less cold but the op is way off towards the end -

Isn't there going to be a point in the models once the block pattern is in the reliable they start to look for the breakdown but it doesn't mean they are right? -

ScottishSnowStorm replied to Paul's topic in Forecast Model Discussion
That because they are both a day apart -

The GFS and GEFS showing quite a few warmer runs for the south next week but the ensembles and tabluex for here in fife central scotland show a different picture Wouldn't need much correction to keep the colder air further south and hopefully it goes that way and not further north -

ECM day 10 mean and a complete circle of easterly winds over the northern hemisphere Would be a bit better if it was further over our side of the hemisphere to keep pulling those deep cold uppers across the land and into europe -

Been watching the models for 8 years and seen a lot of great charts but to see all sorts of ridiculous charts this past week from easterly winds stretching from alaska to florida to complete reverse zonality it has to be said this chart tonight is just an utter thing of beauty and would be awsome to see something like this verify in my lifetime -
Model output discussion - here comes the beast!
ScottishSnowStorm replied to Paul's topic in Forecast Model Discussion
Isn't that because alot of time they get really cold air moving through it is from a high pressure already sinking and moving through the country where as this is an actual block setting up -

It's amazing how consistently this model is showing that deepest cold air heading straight for us How reliable is this model? -
