I did the same with GFS from 6th Jan which was also very good.If only people would read between the lines at general trends an not the vaguries of each run
Early 2009 many occasions occurred of slack dense cold over UK.Streamers set up dumping 9" snow regularly off the Irish Sea through Lancs into Yorks.
Chart not exactly to the day but you get my gist
There will be streamers off the Irish sea which output cannot detect so far out.Do we never learn to get a cold pool in first.
As in "Fry crisp and dry"
Thank god someone else reads it like that.We were doing post mortems earlier and looking to February.Very cold next week and impossible to predict snowfall yet.
And slack does NOT mean no snow with very cold air off the Irish sea
My back garden drivers are telling me January 26th for a convective Easterly.
The canoes have set off from Eastern sea board and tell me depending on shuffling high and currents 25th looks good.
Easy peasy this forecasting lark
