Outlook for the UK over the next 6-30 days

UK Outlook for Monday 27 Mar 2017 to Wednesday 5 Apr 2017:

Monday and Tuesday are expected to be dry, fine and settled as high pressure dominates. Most places will become rather warm by day, although there will be overnight frosts and early morning fog for some. Predominately light winds, but southernmost parts becoming windy, with a brisk north-easterly wind, which will make it feel cold. It will stay mainly dry, fine and settled throughout the rest of the week. However, the far west and northwest will most likely see cloudier and wetter conditions, accompanied by strong winds. Temperatures will stay generally rather warm, and frosts are less likely later in the week. The start of April will probably stay mainly dry and settled, though there is an increased chance of some unsettled spells, mainly in the north-west.

UK Outlook for Thursday 6 Apr 2017 to Thursday 20 Apr 2017:

Much of this period is likely to see high pressure remaining close to or over the UK for the most part. This will bring drier and somewhat warmer conditions than normal for the time of year. If this is the case it is likely that we will see a greater spread in temperatures from day to night, with the risk of overnight frosts continuing for some. However, there may be bouts of unsettled weather at times too, most likely in the west or north-west of the UK, but these will probably be short-lived, as will any colder spells.
