Forecast Summary

  • Regional
  • UK 5 days
  • UK 6-30 days

Regional forecast for Wales

A cold start, then another dry and fine day.

A cold start this morning, with a few localised mist and fog patches. Then a fine and dry day with patchy cloud and sunny spells. Feeling pleasant in the sunshine with just a light breeze. Maximum Temperature 19C.

Tonight:

Dry with clear spells and light winds overnight, so another chilly one. Once again, a few rural mist and fog patches may develop. Minimum Temperature 3C.

Tuesday:

A largely dry and fine morning, but cloud will tend to thicken from the north, with some outbreaks of rain spreading into northern and some western parts through the afternoon. Maximum Temperature 18C.

Issued at: 0500 on Mon 22 Sep 2014

UK forecast for the next 5 days

Dry and fine for most, but rain in far northwest.

Today:

A cold start this morning, with a few localised mist and fog patches, then dry and fine for most once again. However rain will edge across northwest Scotland, then into Northern Ireland and the rest of Scotland into the evening.

Tonight:

The cloud and rain will continue to push southeastwards overnight, possibly just about reaching northern parts of northern England by dawn. Elsewhere, dry, clear and cold once again.

Tuesday:

The band of cloud and occasional rain will continue southwards, across the rest of northern England and north Wales by evening. Largely dry and fine either side.

Outlook for Wednesday to Friday:

Cloud and rain clearing southwards on Wednesday with the odd shower following. Largely cloudy on Thursday and Friday with outbreaks of rain or drizzle for many. Breezy throughout, especially Thursday.

Issued at: 0500 on Mon 22 Sep 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Friday 26 Sep 2014 to Sunday 5 Oct 2014:

Fairly cloudy at first, though some sunny intervals developing for central, southern and eastern parts of the UK. Outbreaks of rain are expected for northern and western areas, more persistent for parts of Scotland and Northern Ireland, although clearer, showery weather should follow for a time. It will be quite windy here too. Temperatures generally near or a little above normal. Into the following week, the north and west are likely to remain the windiest and most unsettled parts of the UK, with the best of the weather further south and east. However, a little rain is to be expected here at times. Temperatures should be a little above normal for most. This general northwest-southwest split in the weather is then likely to continue into the start of October.

UK Outlook for Monday 6 Oct 2014 to Monday 20 Oct 2014:

The broadly northwest-southeast split in weather conditions expected to become established for late September and early October is then showing signs of persisting into mid-October. This pattern would leave southern, central and eastern parts tending to see the best of the weather with conditions often fine and dry. Occasional bouts of rain should still be expected, and mist and fog patches may be a problem during morning rush hours but under fine weather it should feel pleasant. Further northwest, conditions are likely to be more unsettled with more frequent outbreaks of rain, perhaps accompanied by strong winds, temperatures here then often closer to average or perhaps even just below at times.
