Wales

Staying windy with heavy rain in the south. Turning cooler.

  • Another wet day with a band of heavy and persistent rain eastwards across the region
  • Very windy, especially along the south coast where coastal gales are possible
  • Some drier spells developing in the west by later afternoon
  • Very mild
  • Maximum Temperature 15C

Tonight:

  • A damp evening with rain gradually clearing eastwards overnight
  • Clear spells to follow, however blustery showers readily developing and spreading into the west
  • Feeling much cooler
  • Minimum Temperature 4C

Monday:

  • Cooler on Monday with a mixture of sunny spells and scattered showers
  • These heavy at times with the odd rumble of thunder possible
  • Temperatures returning closer to the seasonal average
  • Maximum Temperature 12C

Outlook for Tuesday to Thursday:

  • Sunshine and showers on Tuesday with much lighter winds
  • Heavy spells of rain moving through on Wednesday and feeling colder
  • Often cloudy on Thursday with rain possible later

UK Day 6-7 and week 2

  • Probably a quieter interlude to start this period for much of the UK as high pressure builds with a return of night frosts
  • The high is likely to migrate eastwards however, potentially allowing some outbreaks of rain to move into some some western and northwestern areas along with some stronger winds
  • Whether these conditions edge east into other parts of the country is uncertain, but eastern areas especially may well stay drier and colder through the weekend
  • Into December, and while signals are mixed it looks most likely that high pressure may re-assert itself close to or over the UK, with temperatures generally near average, but some overnight frost is likely, and rather cold by day where any fog persists

UK Week 3 and 4

  • The start of this period looks like being largely settled, with high pressure close to if not over the UK
  • However as we move further into December there are signs that it will become less settled with west or northwesterly types preferred, These will bring some wetter and windier interludes with a risk of some snow, especially for hills in the north
  • These conditions look more likely to dominate towards the middle of December
  • Temperatures generally close to average through the period

Visibility in km. Above 50km is 'good'. Humidity and air pollution make it worse. Theoretical maximum is 300km/200 miles in clean dry polar air.

On the South Downs, at ~ 170m/500ft, the horizon is is ~ 45km/30 miles away. On a mountain at 1,000m/3,000ft, it is ~ 160km/100 miles away. Formula: horizon in km = √ (13 x altitude in m)

Notes

  • The percentage of the moon which is illuminated doesn't vary much with location.
  • A full moon is not just bigger, it is much brighter. A quarter moon (1/2 disk visible) give less than 5% of the illumination of a full moon. You can walk with a quarter 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!

Now would be a good time for a cup of tea.
