Forecast Summary

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

Regional forecast for Wales

A cold start, then another generally dry and fine day.

This Evening and Tonight:

Dry with clear spells and light winds overnight, so becoming chilly once again with a localised rural grass frost possible. Light winds and clear skies will also allow a few valley mist and fog patches to 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.

Outlook for Wednesday to Friday:

Cloud and rain clearing on Wednesday afternoon with the odd shower following. Largely cloudy on Thursday and Friday with a little drizzle possible, especially over hills. Quite breezy at times.

Issued at: 1700 on Mon 22 Sep 2014

UK forecast for the next 5 days

Dry and fine for most, with rain continuing in northwest.

This Evening and Tonight:

Cloud and rain, in the northwest, will continue edging southeastwards overnight, possibly reaching northern parts of northern England by dawn. Elsewhere will be dry, clear and cold with a rural grass frost and a few mist and fog patches likely.

Tuesday:

The cloud and occasional rain will continue southwards, across the rest of northern England and north Wales by evening. Largely dry and fine elsewhere, though further rain in northwest later.

Outlook for Wednesday to Friday:

Rain clearing southwards Wednesday with the odd shower following. Largely cloudy on Thursday and Friday, windy with outbreaks of rain or drizzle in northwestern areas, drier with some brightness elsewhere.

Issued at: 1700 on Mon 22 Sep 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 27 Sep 2014 to Monday 6 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-southeast split in the weather is then likely to continue into the start of October.

UK Outlook for Tuesday 7 Oct 2014 to Tuesday 21 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.
