Horncastle (Lincolnshire) weather

Headline:

Becoming cloudy later

This Evening and Tonight:

A dry night with plenty of clear spells to start the evening, perhaps allowing for a an early frost and a few misty patches to develop. Cloud cover then increasing later in the night, with winds becoming breezy by dawn. Minimum temperature 0 °C.

Friday:

Sunny spells to start, but cloud cover increasing through the day. Risk of a few light wintry showers in the afternoon and overnight. Feeling cold in the brisk easterly wind. Maximum temperature 5 °C.

Outlook for Saturday to Monday:

Cold and mostly cloudy through this period, with rain or showers at times, these sometimes wintry especially on higher ground. Occasionally breezy, accentuating the cold feel.

High pressure is expected to be slow moving and centred to the northeast of the UK over Scandinavia during this period. As a result, east or southeasterly winds will dominate, these bringing cold conditions across the UK from mainland Europe. Some light rain and hill snow is likely at first, particularly across the south of the UK. Dry conditions will probably become more prevalent later in this period with some spells of sunshine or clear skies. However, there is a continued risk of some wintry precipitation at times, particularly along southern and southwestern areas. Temperatures are expected to be below normal during the day with some overnight frost. Brisk winds will exacerbate the cold feel, particularly in the south of the UK.

Weather patterns in the UK are most likely to be slowly evolving. It is most likely that high pressure to the east or northeast of the UK will dominate at first in some form or another, but with time this may decline, allowing an erratic transition to rather more unsettled and less cold conditions. During this transition there is the possibility of periods or rain or snow, at least for a time, but confidence in these details is currently very low.
