East England
Dry with sunny spells but remaining cold.
- After a sunny but frosty start, a mostly dry day is expected with light winds
- Sunshine could be hazy at times and it will remain cold throughout
- Maximum Temperature 3C
Tonight:
- A dry but cold evening with clear spells, leading to an early frost
- Wind strengthening, with some wintry showers moving south in the early hours
- Minimum Temperature -1C
Friday:
- Dry for most with sunny spells on Friday, but remaining cold
- Isolated wintry showers possible in western 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 rain or showers in places, and perhaps also some strong winds for a time
- Temperatures back towards average for most places, but still mild in the southeast
- High pressure is likely to build for a time, particularly across northern areas, bringing an increased risk of some fog and frost
- However, this is likely to migrate eastwards during the second half of next week, potentially allowing some outbreaks of rain to move into some western and perhaps southern areas
- 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
- 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

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!
