Bearing in mind the GFS 12z run from today 15th January to the end of this month, today's GFS has for the areas that matter.
Hugely Positive NAO Oscillation, with waves of both cold and mild Airmasses, brought in from the North and Mid NW and the East N Atlantic Seas, affecting the UK and much of West and NW Europe, areas of PV Low Pressure bringing regular rain and showers mild West and SW winds, and some Cold Low Pressure from same areas bringing some sleet and snow showers to the aforementioned areas.
High Zonality, with some two day spells of Azores High pressure Ridging also in attendance to bring some relief.
Cold NW flow's with brief northerly's also showing up.
I am commenting about GFS out to 348hrs or higher up.
Now I shall see UKMO and the ECMWF updates in half hour and further 1 hour after that!.
Climate is warming up, Scotland and N Ireland and North England still often gets some Winter frost, ice and snow, November to March, but the SE and South UK including S Central England and Wales, together with the West and North through the year, they sometimes get more rain than London and S SE England, where some longer dry fine spells without much heavy rain is seen every year.
The North Atlantic Sea often gets some much Colder Wintry conditions from November to March Months, and Mild SW and South winds tend to be more frequent over the East and SE of North Atlantic Sea, as the Azores High tends to stay in charge.
With this warmth and heat, the Central and South UK has become mostly free of snow and frost.
