Outlook for the UK over the next 6-30 days

UK Outlook for Tuesday 28 Mar 2017 to Thursday 6 Apr 2017:

Many places will be mostly dry with sunny spells on Tuesday and Wednesday, once any early mist and fog patches clear. However, we may see the increasing chance of outbreaks of showery rain affecting south-western parts during Tuesday. Becoming more unsettled generally across the UK from Wednesday onwards. The most unsettled conditions are likely to be across north-western parts, where it will be wet and windy at times, with gales in places. Meanwhile, much of southern and eastern parts will hold onto the driest conditions, although even here some rain and windier conditions are likely. Temperatures will stay generally rather warm, and frosts becoming less likely. The start of April will see a good deal of settled and dry weather across the UK, with unsettled conditions likely in the northwest.

UK Outlook for Friday 7 Apr 2017 to Friday 21 Apr 2017:

Much of this period will see a good deal of settled and dry weather across the UK. However, we are likely to see unsettled conditions with cloud, rain and strong winds affecting the far north and west of the UK at times, particularly at the start of the period. However, such unsettled spells of weather are likely to be short-lived. Temperatures are likely to be warmer than average, but with rather chilly nights at times, with frost and fog in places. Any colder spells are likely to be short-lived, although there slight indications these may be more prevalent later in the month.
