This Evening and Tonight:

An unsettled picture for this evening and overnight with heavy, possibly thundery, showers and strong winds. Showers will start to ease through the early hours leaving most places dry by dawn. Staying very windy with severe gales around south coasts. Minimum Temperature 5C.

Monday:

Aside from a few early showers, Monday will be dry and bright with plenty of sunshine and easing winds throughout. Turning unsettled overnight as heavy rain and strong winds arrive. Maximum Temperature 9C.

Outlook for Tuesday to Thursday:

Heavy rain and strong winds Tuesday with coastal gales. Rain clearing overnight to leave a cold and windy day on Wednesday with some heavy showers. Showery Thursday with lighter winds.

Day 6-7 and Week 2:

Staying unsettled throughout Friday with blustery showers and spells of rain. Some drier or brighter interludes may develop in the afternoon before further rain arrives later. Staying windy, particularly in the south, with a risk of coastal gales. Temperatures near average in the south, but turning colder further north. The changeable theme looks to continue over the next few weeks with showers or spells of rain throughout. Any drier interludes are likely to be short-lived in any one place. Temperatures look likely to fall below average with the risk of wintry showers in the north alongside a low risk of snow along northern edges of rain bands. Some possible frost and freezing fog at times, mainly across northern regions. Strong winds and a risk of coastal gales throughout the period.

Week 3 and 4:

A more changeable spell is expected towards the end of December, with the greatest potential for heavy rain in the south and east at first, with any snow becoming confined to northern hills. A more typical northwest/southeast split looks likely to develop into the New Year bringing rain to the northwest interspersed with showers, and drier periods further south. This could be accompanied by a general upturn in temperatures, as well as the risk of strong winds at times.

Notes

  • The moon's phase or fracillum (percentage of the moon illuminated) doesn't vary much with location.
  • A full moon is not just bigger, its much brighter. A half moon ('50%') give less than 5% of the illumination of a full moon. You can walk with a half 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, and, (ii) if there are hills on the horizon.
  • Of course, you need a cloudless night as well!
