South East England

Cloudy and rainy. Any sleet soon clearing. Drier overnight. Cold.

  • Outbreaks of rain continuing through much of Tuesday, but with any sleet soon dying away
  • Drier in the south Tuesday morning, with some showery rain
  • Slowly brightening up from the north late afternoon
  • Feeling much colder than of late
  • Maximum Temperature 5C

Tonight:

  • Cloudy evening with outbreaks of rain and drizzle continuing to slowly clear away to the south
  • Largely dry overnight, although a few showers may drift across the North Kent coast
  • Minimum Temperature -1C

Wednesday:

  • Feeling cold, but with plenty of sunshine
  • Largely dry, although a few showers may drift across the Isle of Thanet
  • Breezy at times
  • Overnight frosts
  • Maximum Temperature 4C

Outlook for Thursday to Saturday:

  • Cloudier Thursday with outbreaks of rain across southern areas, drier elsewhere
  • Brighter spells Friday
  • Very wet and windy Saturday
  • Low confidence in the risk of any snow
  • Overnight frosts

UK Day 6-7 and week 2

  • After a cold start with increasingly cloudy skies into the weekend conditions turn more to rain, sometimes heavy, with strong winds
  • On the leading edge of this some brief snowfall is possible, this more likely across parts of northern Scotland
  • Strong winds and blustery showers, especially in the west close the weekend before a more settled period develops
  • Late in the month there's still potential for more organised bands of rain and stronger winds, with some wintry conditions possible, though most snow limited to northern hills
  • Conditions remain uncertain at the turn of the month but increased signals for a resumption or continuance of more settled conditions with temperatures mostly just below average for much of the period

UK Week 3 and 4

  • Signals vary in prevailing weather patterns through early December
  • In general, there looks like a trend towards drier and more settled conditions, with high pressure potentially being the more dominant influence 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
  • Temperatures generally a little below average becoming 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.
