It will be quieter and generally settled today and tomorrow, compared to yesterday where we saw quite a few lively showers with hail and thunder across the southern half of the UK. The reason for the weather calming down is a ridge of high pressure building in from the west today. This high pressure cell will drift SE onto the near continent on Tuesday, which will allow Atlantic frontal systems back in from the west, heralding a change to more unsettled weather towards the middle part of the coming week.
On to today, it was a clear and frosty start over many areas with a widespread frost and it will be generally fine and dry for the rest of the day for most parts with good sunny spells, though scattered showers will affect northeast Scotland and down the east coast of England through the day. There will be a strong and cold northerly wind towards the east coast of the UK at first, which will bring a noticeable wind chill, lighter winds elsewhere. Temperatures will reach 12 °C in the south, 9-10 °C in the north. Tonight, any reamining showers near eastern coasts should die out, with much of the UK cold and clear with a widespread frost by dawn. Perhaps a moderate frost in northern areas with temperatures falling as low as -5 °C in sheltered Scottish Glens, a few fog patches may also form in places.
Into the new week, after a frosty and maybe foggy start - Monday will be a fine and dry day with long sunny periods, temperatures similar to today though light winds everywhere. Tuesday will see another frosty start away from the NW, but it will turn milder as cloud and rain spreads eastwards across the UK during the day, accompanied by a strong southwesterly wind. Wednesday perhaps seeing a further band of rain move east followed by blustery showers in the NW. The rest of the week continues on an unsettled theme, with further showers or longer spells of rain accompanied by strong winds at times towards the northwest, though remaining fairly mild.
