Met Office forecasts ‘considerable and extensive snowfall’ across Wales

The Met Office has predicted the likelihood of “significant and widespread snow” as temperatures are expected to drop across Wales.

Their extended forecast for the UK anticipates the possibility of “significant snow” in the middle of the month. Between January 11 and January 20, the forecast suggests a cooling trend with “snow showers” likely across the country.

Presently, temperatures are poised to decrease notably in parts of Wales. Some regions experienced temperatures as low as 0°C at midnight on Sunday, reaching -2°C in the coldest areas.

The Met Office’s long-term weather projection for the UK spanning January 11 to January 20 indicates the persistence of high pressure, predominantly positioned to the north or northwest of the UK. While many areas may remain dry but fairly cloudy, occasional light rain or drizzle could occur, particularly in certain east-facing hilly terrains.

“The best of any sunshine in sheltered western and perhaps southern areas and still rather chilly for most. Towards mid-month, the high will likely decline or reorientate itself to the west or northwest of the UK, potentially allowing colder air with snow showers to filter south across the UK and/or for frontal systems to approach from the southwest. The latter scenario would also bring the potential for significant snow and also perhaps some heavy rain to parts of the south. Either way a more unsettled outlook towards mid-month looks probable.”

The Met Office also forecasts ‘extensive snow’ in the following period. From Sunday, January 21 to Sunday, February 4, the forecast indicates “Through this period, compared to normal, there is an increased chance of colder conditions along with the associated impacts from low temperatures, ice and snow. Whilst colder weather is more likely to dominate, there is also the possibility of further frontal systems at least encroaching from the west or southwest, bringing the potential for more widespread snow to parts of the UK as they butt up against any cold air in place. These would also increase the likelihood of wetter conditions redeveloping, at least in the south, where occasional milder interludes are also most likely.”
