If only it were winter, THIS pattern would be perfect for cold and snow lovers. [s2If current_user_can(access_s2member_level1)] Nice strong blocking high over southern Greenland which the core of this pretty deep trough is centred over the North Sea! The blocky nature of the current pattern means a slow eastward progression with N Atlantic ridging building in mid […]
As pointed out in recent days, we’ve got the chilliest air flow driving south over the UK in several months and it sure is a shock to the system following a mild May, June and July. While chilly with frost and even hill snow across parts of the North as well as Iceland, Scandinavia and the […]
Finally it would appear the African wave train is becoming more pronounced as the Azores high (eastern part of the mid-Atlantic) is weakening and easterly trades are weaken, thus more upward motion! Notice the plume of Saharan dust is further north and west where ridging and large-scale sinking is more prevalent. There’s a lot more […]
The latest CFSv2 weeklies (through Sep 12) shows Greenland ridge/western Europe trough dominance through mid Sep. [s2If current_user_can(access_s2member_level1)] This NORTH ATLANTIC blocking trend is something WE DIDN’T see at this time last year. However, for all you snow geese out there like myself, let’s not get over excited but merely watching this pattern as we head into autumn […]
There are interesting changes going on in the upper atmosphere with blocking becoming more and more of a feature over the North Atlantic. [s2If current_user_can(access_s2member_level1)] For the first time in a fair few months, the NAO is tanking. May this be a reaction to the shift from west to east in the QBO and this being a […]
By driving an autumnal Great Lakes low within an overall warm air mass and you’ve got the recipe for some wild weather. As most of us know, warm and cold do not mix but add TROPICAL moisture into the mix and you’ve got trouble. The perfect ingredients came together for not 1, 2 but 3 MAJOR and historic […]
After a brief respite from the blustery showers and longer spells of rain yesterday, today has seen the return of wetter conditions. [s2If current_user_can(access_s2member_level1)] As we head into the weekend, the GFS has another deep low close to the UK (just off NE Scotland) which looks set to bring another dose of coastal/high ground gales. Windy elsewhere. The more […]
The title says it all. It ain’t happening! [s2If current_user_can(access_s2member_level1)] Current SST’s CFSv2 projections. On par with the modoki Nino or central Pacific based Nino which supports in itself a colder N America and Europe for the winter ahead. Jamstec sees it!

With the exceptions of the West and perhaps surprisingly, East Coast, it’s been a cool, wet but comfortable, low energy summer with a distinct lack of 90 degree heat. The East Coast itself has been average to slightly above average but that’s largely down to warm water keeping the air more humid thus keeping nights warmer. Unsurprisingly, July was […]
Going to take a look at the ECMWF perspective on the next 7-10 days as I’ve focused a lot recently on the GFS. Bertha certainly left her mark and is slowly winding down over the North Sea but unfortunately, her cool, showery farewell looks to linger into Thursday and Friday before a low near Iceland […]
