Weather forecast
Thursday afternoon's highs will remain in single digits for most, with afternoon highs expected to range from 6 to 10C. Overnight lows will widely fall below freezing, potentially dropping to -7C. Strong winds will bring a significant wind chill, especially on northern and eastern coasts, so it will feel colder than the reading on the thermometer would suggest.
The strongest winds will be in north-east Scotland where gusts will touch 50-60mph for a time. Blustery conditions will also affect the east coast of England and it will remain breezy elsewhere. Showers will be blown into northern Scotland, falling as a mix of rain, sleet and hail, with a little snow possible over high ground. Scattered showers will also affect Northern Ireland as well as northern and eastern England, although the majority of these will be of rain.
Thursday night will be one of the most widely cold of autumn so far, with temperatures forecast to drop below freezing in many areas. As well as a widespread frost, a few icy stretches are possible, especially in northern Scotland. Friday will bring more sunshine for many and generally lighter winds, although parts of northern Scotland will remain blustery. Showers are most likely in Northern Ireland, Wales, north-west England and Scotland, where cloud amounts will tend to increase during the afternoon.
