Met Office Forecast

Yorkshire

Dry with increasingly hazy sunshine after a frosty start.

Today:

A cold and frosty start, but with long sunny periods through the morning. However, sunshine will be increasingly hazy in the afternoon as high cloud increases from the northwest. Maximum Temperature 7C.

Tonight:

Staying dry overnight with some clear spells, but breezy at times on the Pennines. Becoming frosty again, with some patchy freezing fog by morning. Minimum Temperature -3C.

Monday:

Patchy freezing fog may be slow to clear, but another dry day with some sunny spells. Breezy at times, especially across the Pennines. Maximum Temperature 9C.

Outlook for Tuesday to Thursday:

Early frost on Tuesday, then cloud and light rain or drizzle spreading southeast. Wednesday and Thursday milder but mainly dry with some sunny intervals, especially in the east.

Day 6-7 and Week 2:

Into the weekend it is expected to be largely dry and settled with bright spells and light winds, although staying cloudy for most. This will continue for the south further into the following week, whilst the north could be wetter and windier at times. Later on in this period, some rain may briefly spread further southeast across the UK, although the most unsettled weather is likely to remain in the north and northwest, where some hill snow is possible. Further southeast drier spells will be accompanied by the best of any brightness, along with the greatest risk of fog and frost. Temperatures will generally be near average, although a little below at times in the north.

Week 3 and 4:

Through the first half of February, we are likely to see a north/south split continuing; with the north being more unsettled than the south. The heaviest of the rainfall and strongest winds are likely to be seen across the northwest. The south is more likely to see drier, brighter conditions with light winds. There is potentially a greater risk of frost and fog patches developing towards the south. During colder, showery interludes, any snow will most likely be over higher ground in the north, but it could fall to lower levels at times. Temperatures will remain close to or above average through the period, though will likely fluctuate as frontal systems pass through, especially in the north.

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!
