Colder Weather ahead – Thursday 18th November 2021 – Sunday 21st November 2021

Hi all,

Autumn is drawing to a close and with winter approaching everyone’s daily weather chat turns to when will it snow; especially after the annual media articles begin to circulate about snowfall and plummeting temperatures. Truth be had, it is very hard to predict snowfall accurately in the UK, more than 5 days ahead, even 3 days in some cases. Our complex weather set-up can see the potential for snow and cold in the coming days, but, like the butterfly effect, a minor shift in the weather systems can mean a cold plunge from the Arctic, gets shifted into mainland Europe. You will be surprised how often this happens in winter and our hopes of some snowy scenes are dashed as milder Atlantic air takes hold. With winter a couple of weeks away, it is looking like the end of November will see it turn much colder and perhaps wintry, but this is subject to change for the very reasons mentioned above.

Thursday: Cloudy, very mild and breezy. The cloud might be thick enough for some local drizzle/light rain during the morning and low-cloud on the hills. Max 14°C

Friday: Still very mild with a south-westerly airflow feeding in around a high pressure. This high means it will be mostly dry but cloudy with some bright spells. Max 14°C

Weekend: Eventually colder and sunnier.

Saturday: Another mostly cloudy day with some brightness. Light rain is expected late-evening and overnight as a weather-front moves in. Max 12°C

Sunday: A cold-front will have moved through the region introducing colder air from the north-northwest but plenty of sunny spells after a ground-frost to start. Odd shower can’t be ruled out, which could be wintry on the highest hills. Max 7°C

Monday: A dry day with plenty of sunny or bright spells on offer. The day is likely to have started with a touch of frost and some isolated mist or fog patches. Max 8°C

Outlook: A lot of dry weather with high pressure close by to our west. Cloudy spells at times but equally some sunny spells. Cold nights with some frost where clear spells last the longest. Towards the end of the week it looks like low pressure will arrive disrupting the settled conditions. The position of the low, i.e. what wind direction we encounter, is uncertain. Just favourable is a cold air-mass, so we would be likely to see bright spells and wintry showers. So, just as we near winter, some sleet or snow showers, especially on the higher ground, becomes a possibility. No sign of the -11°C and widespread snowfall that those media articles promote though – just a standard late-Autumn/early-Winter cold-snap.
