Yesterday, London managed 15.9C at Kew Gardens wheras in the far north of Britain Fyvie Castle Aberdeenshire only reached 7.3C. By Saturday 7.3C will be considered balmy. People keep saying to me “Oh isn’t it cold!” Well no, not yet, wait until the cold Arctic air is spilling down through the UK this weekend.

No more low pressures from the Atlantic for several days. In fact the next area of low pressure to affect the UK looks to be one forming in the North Sea on Friday night/Saturday. Accompanied by 524/520 dam thickness air, we are going to have to mention snow in those northerly winds. (528 thickness line is a starting rule of thumb for looking for snow rather than rain in precipitation. Thickness is the vertical distance between pressure lines, commonly 500 and 1000 mb, cold air has a lower, thinner value).



Anyway, the blast of winter for this weekend should wait a moment.

Today

There are two main areas of wet weather this morning and a scattering of showers for western counties of Britain. An occluded front is bringing rain into northern Scotland and for SW Britain an extended front is waving up from the Western Channel. In between, there will be a lot of bright sometimes sunny weather with just the odd shower.



For N.Ireland there will be a good deal of fair bright weather but interrupted at times by lines of showers from the west. Freshening west winds will make it feel cooler, 7 in the west, 10C for Belfast.
