Friday is a day to watch

Monday may still be interesting as well.

Have a look at the developing storm off Newfoundland in this satellite image, this is the one heading for northern Britain on Friday night, and it looks like a pig of a storm now:

(for later readers, this image will update, as of 23z Wednesday it had the look of a pig in the cloud pattern) ;)

It's looking more like a horse now, perhaps a sea-horse, and it's got its eyes on France, but soon it will spot the British Isles and head that way.

March in like a lion, that's for sure ... I think this one will be very windy, it is on that sort of track where wind speed can continually increase due to forcing between the low centre and the resistant jet keeping milder air over the south. This is why on another thread I mentioned that it could become very mild in southern England, the winds go around to about 270-280 deg which is off the warmer land surface for the south coast. The thickness values also resist erosion despite a turn of winds to the WNW then NW. Also in the J-field analysis, J-I overtakes J-III near transit, which often leads to gustiness along the J-I energy track even in the absence of convection. For all these reasons, I would speculate gusts to near 90 mph in the usual exposed areas across N Ireland, s Scotland and n England, but this will get windy in other districts too.

The winds will howl on and off for several days, it will turn a lot colder by Monday and snow could be in the picture for some by then. A secondary storm that forms in the lee of this Friday-Saturday low, then moves southeast into the North Sea and that looks very windy for eastern England by Wednesday, with a rain-snow mix indicated by the thickness values (snow at elevation inland).

A very active start to March which can often be the windiest month.

T+120 I know ,but this baby looks pretty evil to me and maybe wintery?

well lets just say if that pulled off, virtually all of the uk would be in the grip of a snow event. the heart of the low is enough to give whiteouts with the tight isobars,in scotland and even the southern uk is at risk for strong winds. possibly a little overplayed, but we shall all see what bbc weather predicts for monday by eight pm.

The east coast could be the place to go to get your weather shots on Good Friday. The seas should be good enough anyway.

Winds up to 60 mph here averaging 34 mph. Like I said most likely the most noteworthy event of the weekend. This is lasting longer than the "Other major storm" we had earlier this month.

You can keep that sort of speed, although I know someone not too far away from me that wouldn't agree, would you Cookie!! :o

Calmed down up here now, average of 25 knots and the sleety squallys we had earlier seem to have passed through.
