East England
A wet start, becoming dry with sunshine and showers Tuesday.
- Rain gradually clears from the coast with isolated showers following behind
- These soon fizzle out leaving a largely dry second half of the night
- Isolated patches of fog developing by dawn
- Minimum Temperature 4C
Tuesday:
- A fine and sunny start for many, any fog patches soon clearing
- Isolated showers develop by late morning and into the afternoon
- Light winds
- Maximum Temperature 17C
Outlook for Wednesday to Friday:
- A wet start Wednesday morning, becoming cloudy with isolated showers
- Dry with sunny spells on Thursday
- Mist and fog patches Friday morning followed by hazy sunshine
- Temperatures near normal
UK Day 6-7 and week 2
- Fairly changeable at first, with cloud and rain moving slowly east across the UK, probably easing and breaking into showers as it does so, with more settled conditions developing later in the weekend away from the far northwest
- Into the following week, it will most probably be high pressure dominated, with large amounts of fine weather, and perhaps the odd heavy shower, especially in the south
- Any more unsettled interludes liable to be brief and mainly affecting western or northwestern UK
- However, there is a small chance of an alternative scenario coming off, with cloudier and wetter weather more extensive, especially across the south and west of the UK
- Winds are most likely to be light, with temperatures probably at or slightly above normal
UK Week 3 and 4
- The period begins with the two alternate scenarios continuing, most likely widely dry and settled, but a lower chance of more unsettled and wet conditions, especially in the south and west
- Towards the middle of the month signals become weak and mixed, with more balanced chances of dry / settled and wetter / unsettled conditions
- But compared to the start of this period, this represents an increased chance of more unsettled / wet conditions
- There is however a strong signal for temperatures to be at or above average

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!
