After a cold start, frosty in the south, Wednesday will be a generally fine, dry and sunny day across England and Wales as high pressure begins to build in from the west, just an isolated shower risk towards western coasts. Scotland and N. Ireland will also remain mostly dry, but after a bright or sunny start, it will turn cloudier from the northwest, with rain arriving in the far northwest by evening. Temperatures reaching highs of 10-12C generally.
High pressure builds in from the west for the rest of the week, settling the weather down, but with it, some cold nights.
Another cold start on Thursday, with a frost likely and also some fog patches across parts of England and Wales at dawn. Fog maybe slow to clear across parts of the south, due to little wind, where it lingers temperatures staying in single figures. Otherwise a dry day for most, with a good deal of sunshine across England and Wales, more in the way of cloud across Scotland, N. Ireland and far north of England – which may be thick enough to bring the odd bit of drizzle. Temperatures will actually be lowest in the south, where they’ll reach 10-11C, in the north, where there will be a brisk westerly breeze, 12-15C.
Fog perhaps more widespread to start Friday, staying chilly where fog lingers, otherwise another fine and dry day for most, with light winds and sunny spells in places. Temperatures reaching 9-12C.
Another mainly dry day on Saturday, after a bright start, perhaps turning cloudier across the south with an easterly wind picking up, northern areas staying generally sunny.
High pressure retreats east by Sunday, allowing low pressure to the southwest to have increasing influence across the south, perhaps bringing showery rain north across England and Wales through the day, but also milder air with temperatures returning to the mid-teens. Scotland and N. Ireland probably staying dry and bright.
