East England
Cloudy and windy with heavy rain during the afternoon.
- Outbreaks of rain are possible across western areas through the morning, before a band of sometimes heavy rain gradually moves south-eastwards through the afternoon
- Very mild
- Windy with gales for eastern coasts
- Maximum Temperature 16C
Tonight:
- Periods of heavy rain slowly easing from the northwest with most parts dry by dawn
- Winds easing overnight but staying very mild
- Minimum Temperature 8C
Monday:
- Early rain clearing the far east leaving sunny spells and mainly dry with lighter winds, and only isolated showers
- Temperatures generally close to average
- Maximum Temperature 11C
Outlook for Tuesday to Thursday:
- Sunny spells and mainly dry with lighter winds on Tuesday
- Wednesday wet and windy weather is likely to arrive
- Thursday dry and fine, light winds
- Temperatures generally close to 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 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!
