Re: The Mother of all Snow Ramping Threads 2...
Seems fairly good cross model agreement for the week ahead too, albeit the UKMO which seems to be going off on its own completely different to the others.
ECM +24
GFS +24
Moving onto Tuesday at the +48hr marker we have the following from the models.
ECM +48
GFS +48
As we can see, the colder upper 850s are starting to drop down from the North, By Tuesday lunch, GFS predicts the entire Scottish highland to be under -8c, whilst the ECM keeps them a hundred miles or so further North.
Into Wednesday, at +72hrs we have these.
ECM +72
GFS +72
Again, fairly good agreement between the two, give or take 50miles or so each way. -10c 850 temps to the north of Scotland. Both models agreeing on the -8c uppers across whole of Scotland.
Onto Thursday +96hrs, the charts are very similar to Wednesdays in terms of 500 and 850hpa.
Into the weekend, 850hpa temps should rise a touch to 0c only briefly before the cold drops in again from the north as said in my post above.
I could be wrong with the above, but next week 'should' see a noticeable drop in air temps
