Met Office Forecast

Wales

Rather cloudy overnight with heavy, potentially thundery, showers pushing northwards.

This Evening and Tonight:

Warm and cloudy overnight with a light breeze. Largely dry in the north, although showers will still develop here and there. Heavy, and potentially thundery, showers will linger along the south coast, pushing further inland through the early hours. Minimum Temperature 13C.

Saturday:

A rather wet and cloudy day, with heavy showers continuing to spread northwards through the morning and persisting across the country well into the night. Maximum Temperature 21C.

Outlook for Sunday to Tuesday:

Cloudy with heavy and potentially thundery downpours on Sunday, becoming more persistent on Monday. Brighter on Tuesday with spells of sunshine possible but perhaps the odd thundery shower too.

Day 6-7 and Week 2:

The beginning of this period is likely to be generally unsettled with showers and longer spells of rain at times, potentially becoming heavy in places. There is also a chance that there could be some further thundery weather, although this would most likely be confined towards the east and southeast of the UK. It is likely to be windier than of late, especially in the south and west where there is also a risk of gales. Temperatures should start rather warm for many, despite the spells of unsettled weather. However, temperatures may cool slightly by the end of this period with freshening winds from the northwest likely to create a more widespread risk of gales.

Week 3 and 4:

Although confidence is low for this period, it is likely that conditions will become more changeable with drier and brighter days interspersed with periods of rain and strengthening winds. Temperatures should be around the average for this time of year. Towards the end of this period, there are some tentative signs that high pressure could begin to dominate, especially across the south of the UK, with a return to more settled conditions.

Day length is dusk to dawn. Times will vary a little if there is a hill on the horizon.

It should still be light enough to read at dawn and dusk, so there will be enough light for walking even earlier (later).

Notes

  • The moon's phase or fracillum (percentage of the moon illuminated) doesn't vary much with location.
  • A full moon is not just bigger, its much brighter. A half moon ('50%') give less than 5% of the illumination of a full moon. You can walk with a half moon if its high in the sky (after dusk for a growing moon, before dawn for a shrinking moon).
  • Sky glow (light reflected by air or clouds) from nearby cities, and especially snow on the ground also effect light levels.
  • Times will vary a few minutes, as (i) these figures are for the centre of the county the walk is in, (ii) if there are hills on the horizon, and (iii) if you are on a hill
  • Of course, you need a cloudless night as well!

Today

Isolated heavy and possibly thundery showers with a risk of thunder at first, and again during the afternoon and evening.

Summary Isolated heavy showers with a risk of thunder during the early hours should clear soon after dawn leave a mainly dry but cloudy morning. Further heavy showers and thunderstorms will redevelop in the afternoon and continue into the evening. Whilst not everywhere will see a thunderstorm, where they do occur, large hail, frequent lightning, strong and gusty winds and flash flooding may result.
Chance of Cloud free tops 90% at first but deteriorating quickly during the early hours to 30% as broken low cloud develops near 400m, especially over the east of the Brecons. Improving to 90% or better late morning onwards as cloud lifts clear of all but the highest peaks. Falling to 20% or less late evening as cloud redevelops near 400m, mainly across the east of the Brecons.
Ground conditions
Visibility Generally very good, but falling to poor in heavy showers and thunderstorms when even nearby landmarks may become hard to make out. Very poor on the highest routes at first and during the evening.
