Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 4 Apr 2015 to Monday 13 Apr 2015:

Probably a fair amount of cloud around Saturday and Sunday. Also most likely a good deal of dry weather, though some southern and western parts may see some early rain Saturday and some eastern parts may catch isolated showers this weekend. Winds will be mainly light, and daytime temperatures most likely near or just below average. Into Easter Monday, outbreaks of rain and stronger winds are likely to affect northwestern parts, whilst other areas remain largely dry and bright. The unsettled conditions then look likely to spread further across the UK by mid-week, many parts breezier then too. Thereafter, northwestern areas are likely to have the most changeable conditions with spells of rain interspersed with colder, showery weather, with the best of the drier and brighter conditions to the southeast.

UK Outlook for Tuesday 14 Apr 2015 to Tuesday 28 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.
