Brightest in the northwest. Cloudier further southeast.


A largely dry day for most. Northern and western areas will enjoy the best of any sunny spells, especially through the morning. More cloud will affect southern and eastern parts, with the cloud thickening later. Staying very mild. Maximum Temperature 16C.


Turning mainly cloudy overnight, with hill and coastal fog developing in places. It will be generally dry, but the odd spot of drizzle is possible. Remaining very mild. Minimum Temperature 10C.


A dry but rather cloudy day. There will be some limited brightness, particularly to the north and west of high ground, with thicker cloud further southeast. Remaining very mild. Maximum Temperature 16C.

Outlook for Saturday to Monday:

Mainly dry through the weekend with increasing amounts of sunshine developing, before cloud increases again by Monday. Turning colder through the period, accentuated by strengthening winds.

Day 6 to 15

For much of next week it looks mostly cloudy with the best of the brighter spells in the west. Showers may affect eastern and some central areas, and these could turn wintry over hills. It will be cold, especially in the south, with this accentuated by the brisk wind. Night frosts are likely and could become widespread at times. Although many places should stay dry, some showers or even longer spells of rain could affect some southern and central areas, perhaps with hill snow. Similar conditions will probably continue into the following weekend and the last week of November although it could become more unsettled from the west or south. There's also a small chance that wintry showers may develop more widely across northern and eastern areas for a time.

Day 16 to 30

This period is likely to begin with a continuation of the mainly dry conditions, with variable cloud and some sunshine, once morning fog patches clear. However, there will be an increasing chance of some more unsettled interludes developing, with showers or longer spells of rain spreading to many areas at times. Temperatures are likely to be below average overall, with a greater incidence of frosts than usual and any milder interludes likely to be short lived. With more generally colder temperatures, there will be an increased chance of snow during spells of unsettled weather, especially for the north.
