East England
Becoming sunny today. Cold and frosty again tonight.
- Sunny today, after a cold start with frost for many places, with areas of low cloud, mist and fog slowly clearing
- However, the sunshine will become weaker this afternoon as high cloud arrives
- Maximum Temperature 9C
Tonight:
- High cloud will thin to allow clear conditions to develop, leading to a widespread frost and patchy mist or fog to form
- Minimum Temperature -3C
Sunday:
- Overnight mist and fog will clear to leave a dry and sunny day with light winds and temperatures slightly above average
- Maximum Temperature 10C
Outlook for Monday to Wednesday:
- Becoming generally cloudier but remaining dry, with some bright or sunny spells
- Chance of overnight frost and fog at first, with daytime temperatures gradually rising to become mild for Wednesday
UK Day 6-7 and week 2
- A split in weather conditions is likely across the UK at first during early March
- Northwestern areas will see some rain and stronger winds at times, as Atlantic weather systems arrive
- These spells of wet and windy weather will drift southeast to some degree, but will weaken
- High pressure is likely to have more influence across the south of the UK, at least at first
- However, through this period there is an increasing chance of changeable conditions becoming more widely dominant across the UK with more in the way of rain at times for all areas, even in the south
- Although, there will still be some drier interludes between these periods of unsettled conditions
- Temperatures overall likely to be above average and potentially very mild early in this period
UK Week 3 and 4
- The middle of March is most-likely going to be quite changeable and unsettled with spells of rain and strong winds in most areas, especially the north and west, with rainfall amounts probably above average
- Some drier interludes are also likely between time though, especially in the south and east, and temperatures on the whole will be a little above average
- Later in the month, there are signs that high pressure to the south could start to dominate once again, with extended dry and bright conditions perhaps developing more widely

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!
