South East England

Rain, sleet and hill snow in south. Fine elsewhere. Cold.

  • A mostly cloudy start, especially across southern and western areas
  • Breezy with rain and sleet in southern parts, turning to snow on hills
  • Brightening up during the afternoon
  • Elsewhere fine, with sunny spells
  • Staying cold across the region
  • Maximum Temperature 4C

Tonight:

  • A largely dry night with clear spells, perhaps the odd wintry shower in northern parts
  • A cold night with icy stretches possible where it has been wet
  • Wind strengthening overnight
  • Minimum Temperature -2C

Friday:

  • Dry for most with sunny spells on Friday, but remaining cold
  • Isolated wintry showers possible in northern areas
  • Wind easing
  • Maximum Temperature 5C

Outlook for Saturday to Monday:

  • Becoming very windy Saturday with much milder air arriving and bringing heavy rain, this clearing later Sunday
  • Remaining windy on Monday with showers, but slightly cooler than Sunday

UK Day 6-7 and week 2

  • An unsettled start, with strong winds and some showers for many parts, these most frequent in the north
  • Temperatures easing back towards average for most places, but still mild in the southeast
  • The strong winds will make it feel rather cold though
  • It then looks like turning colder for all parts, with a return of wintry showers for a time, especially in the north
  • Conditions then look like settling down as high pressure briefly builds across the country, this bringing a risk of some stubborn fog patches as winds ease
  • It may turn unsettled and milder again later next week
  • Into December, high pressure may re-assert itself, with temperatures generally close to 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
  • there is also a chance of more changeable weather patterns, which would see Atlantic weather systems periodically move across the country
  • 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

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.
