East England

Mostly cloudy with the odd spot of drizzle possible.

  • A damp and murky day with light winds and with the extensive low cloud perhaps producing a little further drizzle at times
  • Temperatures near normal
  • Maximum Temperature 10C

Tonight:

  • Clear spells developing in the west allowing areas of mist and fog to form, remaining damp and murky in the east
  • Light winds
  • Minimum Temperature 6C

Thursday:

  • Mostly dry, but with variable, often large amounts of cloud and perhaps some patchy overnight frost and fog
  • Temperatures much cooler than of late
  • Maximum Temperature 7C

Outlook for Friday to Sunday:

  • Mostly dry, but with variable, often large amounts of cloud and perhaps some patchy overnight frost and fog
  • Temperatures slowly trending downwards to become rather cold into the weekend

UK Day 6-7 and week 2

  • This period is expected to see a transition, possibly lasting over several days, between the settled, dry, and often dull conditions expected over the next few days, to something more unsettled
  • Sunday itself is likely to be rather cloudy and cool, with outbreaks of rain in the west drifting slowly eastwards
  • The start of the following week will most likely see more settled conditions with light winds becoming re-established, with a chance of rain in both the far north and the far south, and a smaller chance that the rain could become more widespread
  • Later in the week, periods of much wetter and windier weather will most likely become more prevalent, from northwest to southeast, alternatively there is a very small chance of colder, drier, but perhaps wintry, easterly winds

UK Week 3 and 4

  • A dominant flow from the Atlantic looks likely through this period, resulting in an unsettled, milder and windier than average period
  • This is likely to result in areas of rain and periods of stronger winds affecting most if not all parts of the UK at times, though with the wettest and windiest weather probably occurring towards the north and west
  • However, the potential for brief colder spells with associated frost, ice and snow remains, following any deep lows crossing the region

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

  • Max Height (solar noon) is when the sun is highest in the sky.
  • Day length is dawn to dusk as there is enough light for walking for at least 30 minutes before sunrise and after sunset, even on an overcast day.
  • At 'Light' (nautical dawn) the horizon becomes visible. At 'Dawn' (civil dawn) there is enough light to read, and drivers can switch their lights off. Finally the sun rises.
  • After sunset, there is still enough light to read until 'Dusk' (civil dusk) or lighting up time for drivers. The horizon is still visible until 'Dark' (nautical dusk).
  • Times will vary if there is a hill on the horizon.

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
  • Sunlight is ~ 1,000,000 times brighter than moonlight.
  • Of course, you need a cloudless night as well!
