UK forecast for the next 5 days

Mostly fine overnight, but patchy fog developing in east.

A mostly fine and dry evening and night, however patchy low cloud and fog will spread into eastern counties of England. The far north of Scotland will also see patchy cloud and some showers, which could be locally heavy.

Tuesday:

Low cloud across eastern England will clear through the morning although may persist along the coast. Northern Scotland also seeing further cloud and showers, but elsewhere dry with warm sunshine.

Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 25 Apr 2015 to Monday 4 May 2015:

It is likely to be unsettled throughout Saturday and Sunday with spells of showery rain and breezy conditions affecting many regions. During the rest of the period, most areas will be affected by bouts of unsettled weather with showers and longer spells of rain. Some heavy showers are possible, and during the last few days of April, some of the showers may also be wintry over hills. In spite of the rain and showers there should be some brighter periods too. Conditions are also likely to turn cooler than of late during late April, more especially in the north, and this change may happen as early as next weekend. Windy at times too, especially in the north.

UK Outlook for Tuesday 5 May 2015 to Tuesday 19 May 2015:

The unsettled conditions that will become established during late April are likely to persist into early May. Beyond this, there are no strong signals regarding likely weather types. As such, the most likely scenario is for weather conditions during this period to be fairly typical for the time of year with spells of fine and bright weather interspersed with occasional bouts of more unsettled and changeable conditions. Daytime temperatures are likely to be above average when conditions are fine and near or a little below average during unsettled weather. As is common for the time of year, spells of settled weather may be accompanied by chilly evenings with isolated overnight frost in rural areas.
