Wales

Storm Bert to bring possible disruption this weekend.

  • Storm Bert bringing a widely unsettled and potentially disruptive day with heavy, persistent rain, hill snow and gales, severe along coasts
  • Turning noticeably milder, resulting in a rapid melt of lying snow
  • Maximum Temperature 15C

Tonight:

  • Remaining unsettled this evening and overnight with further spells of heavy rain, especially over the highest ground, and becoming persistent by dawn
  • Very strong winds but mild
  • Minimum Temperature 8C

Sunday:

  • A damp start with heavy rain clearing
  • Becoming drier into the afternoon with the odd shower and bright spell
  • Mild and windy
  • Maximum Temperature 13C

Outlook for Monday to Wednesday:

  • Sunshine and showers through Monday, these becoming less frequent on Tuesday
  • Further rain possible on Wednesday
  • Strongest winds easing with temperatures returning closer to the seasonal average

UK Day 6-7 and week 2

  • Probably a quieter interlude to start this period for much of the UK as high pressure builds across the north with a return of night frosts
  • However there is still a risk of some rain across southern parts of the country on Wednesday, although the northern extent of this is uncertain
  • The high is likely to migrate eastwards during the second half of next week, potentially allowing some outbreaks of rain to move into some some northwestern areas along with some stronger winds
  • 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

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!
