Scandinavian high to bring colder weather but how cold?

yeah, it looks like we'll have to wait till Feburary again for snow.

it'll be worth if we get a polar low coming down from the direction GL - well maybe not for the east and south east of the country!!

The air is not cold enough over the country for it to snow,at best it be cold rain if and when the mild air breaks through.

Could be worse,could be mild dank drizzle. Atm some of the models sink the HP into the continent,some split it and which stalls the atlantic moving totally across the country.See what the 18z brings later on.

Still a long way off and there is confusion in model agreement,it could upgrade but also downgrade further.Some would like the HP out of the way,id prefare it to take up residency over Oslo.

Yup fupping unbelievable etc
However what I meant by "recent definitions" is that lately FI is any model output predictions for weather more than 96 hours past the runs starting point.
FI usually stands for fantasy island in that people only bother looking at it and using it in threads when it shows charts that hint at snow or whatever it is that is their favourite weather.
Thats something I've always found pointless except for discussing theories or trends.
Mind you the best way lately to discuss trends is by comparing variations between runs inside the 96hr timeframe.

True.As posted earlier in a thread,90% of the time a zonal forecast would be accurate within 4 days,apart for precip totals and temperature at 4 days away but based on wind direction,a general mild or cold zonal would be guessed.Obviously more accurate closer to time.

In the recent HP setup,it is near impossible to be accurate in a forecast for a given region even in close proximity on a daily basis for sun,cloud cover and temperature for that particular area but yes the majority of the time it will be dry.As it was an Azores high it will contain moisture and result was cloud cover or the stratus muck we all know it as.
It be a different story if it was an Arctic high with the crystal clear air and lower temps with precip dependant on other factors.

Now with the models and FI,this was not recognised in the zonal flow we had just gone at 5 days out,so who can call it in 7 days.FI will always make for good reading but be taken at face value with room for upgrades or downgrades or just the direct opposite.
Whats christmas going to be like? Well i could not tell you nor anyone else,but with a glimmer come the 18z on the 20th and more defined come the 23rd.

Latest from Met Eireann:

Present indications are that it will be relatively mild on Christmas Eve with rain gradually spreading from the west during the latter part of the day and then drier, brighter and cooler weather following slowly from the west on Christmas Day.
