Second Child of Nadine Coming?
There is the threat of very wet weather for the southern half of the UK during the latter part of this week. Believe it or not, the low forecast to track somewhere across the southern half of Britain on Friday looks to be born from the remnants of Tropical Storm Nadine, which is still wallowing to the southwest of the Azores Islands before drifting to the north of the Azores later this week, before becoming ex-tropical. Nadine’s ‘second child’ will form as a wave along a frontal zone separating warm moist air of tropical origin and cold air sinking down from polar regions. So where the two contrasting airmasses clash, we can expect to see a lot of rain forming, with the potential for up to 40-60mm to fall in a 36 hour period over a wide area of southern Britain from late Thursday through to early Saturday, perhaps locally as much as 90mm. So there may again be a risk of flooding in places, given already saturated ground.
Before then, we have another cool, blustery and showery day in store across many areas. Showers, mostly in the north and west at first, will spread across other areas through the morning. There is a risk of hail and thunder with some of the heavier showers. Though there should be some sunny spells in between the showers and hopefully they should become fewer through the afternoon away from the northwest, where the showers may merge into longer spells of rain. Temperatures will be on the cool side, ranging from 11-13C in the north to 13-15C in the south.
After a chilly start, Thursday is looking to be the best day of the week, with most places dry, sunny and feeling a little warmer too. Though still a risk of a few heavy showers towards western coasts. Later in the evening and into Friday, rain will spread east across much of England and Wales, heaviest across central and southern areas. Scotland, however, should be bright or sunny on Friday with scattered showers in the west.
Then for the weekend, it’s not looking too bad – with mostly dry and bright conditions likely - courtesy of a ridge of high pressure building across the UK, though the far south of England maybe cloudier with some rain at first. Sunday is looking mostly fine and dry with sunny spells, though it looks like it may cloud over across the west Sunday afternoon, with rain arriving here in the evening.
