Stornoway (Na h-Eileanan Siar) weather

Headline:

Showery rain for a time otherwise dry and bright

Today:

It will be largely dry with bright spells, but remaining quite cold. A band of cloud and some outbreaks of showery rain spreads south through the middle of the day. Freshening northerly winds later. Maximum temperature 7 °C.

Tonight:

Showers feed in from the north, wintry over hills. Staying dry with clear spells towards Wester Ross allowing a widespread frost to develop. Freshening northerly winds Minimum temperature -3 °C.

Monday:

Feeling cold as showers feed in from the north, mainly into Caithness and Sutherland with perhaps the odd shower towards Inverness-shire, these wintry over hills. Drier in the west. Breezy. Maximum temperature 5 °C.

Outlook for Tuesday to Thursday:

A cold few days. Persistent rain, sleet or snow on Tuesday. Scattered wintry showers on Wednesday and Thursday. Cold and strong northerly winds, gradually easing through Thursday.

A widespread and in places sharp frost to begin Friday. Then a transition during the day to less cold and more generally unsettled conditions as Atlantic weather fronts make inroads into the UK. These will bring spells of rain potentially quite widely, though the wettest conditions through the latter part of November may occur across more southern areas. There is also the potential for some windy weather to develop at times, again this perhaps more likely further to the south. Compared to the preceding few days, a reduced likelihood of snowfall, though some upland snow remains possible in the north. Temperatures probably returning closer to average, generally speaking, for late November, and perhaps becoming mild at times in the south.

Whilst there is a lot of uncertainty as to the flavour of weather affecting the UK into December, there is a greater chance than normal of slower evolving weather patterns. This could bring rain or showers with hill snow also a possibility, mainly in the north. However, there are also likely to be periods of high pressure at times, bringing more in the way of dry weather, which would increase the chance of overnight fog and frost. Overall, temperatures close to average are most likely, but some colder spells are also possible, especially should any prolonged settled spells develop.
