Well the overall synoptic for the next 10 days is very uncertain.
However there is growing consensus that it will turn colder and much more settled. There is chance as the period progresses that a pulse of very cold air from the east could force west across Ireland. Southern England will be more at risk of the intense cold.
A massive Siberian block is forcing west and as early as Sunday is making its presence felt by pushing an initial cold pool west. After this there is growing uncertainty but a good chance that the block will advance further during Wednesday February 1st and slowly an extremely cold flow will push first into England and slowly into the east of Ireland. At present it appears it will remain rather settled but there will be increasing chances of snow if the synoptic is allowed to develop.
Meanwhile, the block as early as Sunday is showing signs of upgrade, with the initial cold blast pushing further west, just pushing into the east coast of Ireland by Sunday afternoon/evening.
Frontal bands will be attacking from the west with heavy moderate to heavy rain developing countrywide during Saturday night and Sunday. The rain will make painstaking progress eastward during Sunday and as the cold air from the east undercuts the rain it is possible it will turn to snow, at first over far eastern districts but then moving west.
The precipitation is expected to stall over the country for up to 48 hours, and we will be watching carefully the output in the coming hours and days to see whether the cold pulse from the east will be enough to turn this to snow.
I just thought i would throw this out there as is less than 72 hours away and could prove to be very interesting.
