Today's look of the GFS 00z, UKMO 00z and ECMWF 00z Model Output suggests that we have Tuesday 3rd Jan., to Thursday 5th Jan., less cold air, but by Friday and Saturday 6th and 7th Jan., we get more Cold NW to Northerly type Arctic cold plunge, with widespread night frost and chance of hill snow, and for lower levels in the North. After that the North Atlantic Blocking High should move back from our West and NW, by Sunday 8th Jan.
Low Pressure diving SE from Central N Canada at 192-216- through NW Atlantic join with a Low from Mid W N Atlantic merge together with WAA going up as they merge in NW Atlantic even at 240hrs.
NE Europe Sunday 1st to Thursday 5th looks set for very cold Cyclonic Arctic Polar Vortex Cold wintry spell of weather.
At 192-216hrs the High over NW Atlantic intensifies and merges with the Greenland High, a Mid N Atlantic set of two Low Pressure systems that head to 500 miles South of Iceland by 4-5 January merged with SE tracking Newfoundland far NW Atlantic Low with cold NorthNW plunge formed in it as cold NW Atlantic High and Greenland High merge. Another chance for a second round.
NW to SE Tracking PV Express C and E Canada to NW half of Atlantic latter part of 1st week NY 2017!!, the ECMWF and GFS I hope that next five days this prediction keeps maintained.
😃☔🌞⛈❄️🌊. There could be wet and Windy weather on Thursday to Saturday as well, with wintry conditions up in NW and North UK by Friday-Saturday.🔚.
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.
