US Blizzard NOT UK-bound But Turning Colder With Moisture Plume Extending Back To Caribbean

The next front pushes across the UK today bringing a spell of wind and rain followed by blustery showers of which turning increasingly to snow over high ground. Certainly a much cooler feel for all.

It was mild out ahead of the front yesterday as temps climbed to 18.4C at Gravesend, Kent.

The big blizzard which hit the interior Northeast US hard WON’T impact the UK as some media sources suggest but what we are going to see is an increasingly unsettled and colder theme here across the UK TOMORROW INTO SATURDAY.

As you can see from the GFS charts below, we’ve a broadening low (once the blizzard) lifting out of Newfoundland into the NW Atlantic, broadening the trough over eastern North America while we’ve a large Azores high pretty much covering the entire eastern Atlantic extending into the southern UK.

In between the trough/ridge, we’ve somewhat of an atmospheric river developing with plume of moisture taking aim at Northern Ireland, Scotland and N England/Wales which extends all the way back to Central America.

The moisture plume may bring a sustained period of heavy, wind driven rain which shall take aim from Central Highlands to Southern Uplands with precipitation falling largely as snow above 150m north of the Central Lowlands tomorrow into Saturday.

As for next week, well the GFS has an interestingly colder solution as low pressure leaves Greenland and dives towards the southern UK all the while heights build north over the Atlantic.
