Outlook for the UK over the next 6-30 days

UK Outlook for Friday 3 Apr 2015 to Sunday 12 Apr 2015:

Many areas away from the far northeast of the UK will probably be dull and cloudy with outbreaks of rain on Good Friday. However, it should be mostly dry during the weekend with variable and often large amounts of cloud. Winds should also be light or moderate and daytime temperatures near or slightly below average. On Easter Monday and Tuesday, thicker cloud, outbreaks of rain and stronger winds may affect western and northwestern parts of Britain but most other areas should be dry with sunny spells. Temperatures show signs of becoming a little above average. Thereafter, northwestern areas are more likely to have the most changeable conditions with spells of rain interspersed with colder, showery weather. Meanwhile, the best of the drier and brighter conditions should be to the southeast.

UK Outlook for Monday 13 Apr 2015 to Monday 27 Apr 2015:

During the second half of April conditions are considered most likely to be broadly typical for the time of year. As such some spells of fine, dry weather are likely, the best of these probably over southern regions, but occasional bouts of more unsettled weather with rain or showers should also be expected, perhaps more especially in the north. During fine spells maximum temperatures are likely to be near or a little above average, whilst during showery spells daytime temperatures may well be below average, especially in the north. Some cold nights, with localised frost, are also likely at times.
