West Wales set for cold snap with frost and fog forecast

Rain is expected to ease on Wednesday morning as brighter conditions spread across much of Wales.

Forecasts indicate temperatures will fall during the second half of the week, bringing cold mornings to Pembrokeshire, Ceredigion and Carmarthenshire.

Daytime temperatures are expected to stay near average on Wednesday, with a regional maximum of about 8C.

After sunset, however, temperatures are forecast to fall quickly, producing widespread frost.

Thursday is expected to start with frost and patchy fog before becoming dry and bright.

Brisk winds could initially make conditions feel colder than thermometer readings suggest.

In Pembrokeshire, coastal influence may keep exposed communities slightly less frosty than sheltered inland areas, but wind chill may still be sharp.

Motorists travelling through rural areas should prepare for frost on untreated roads and reduced visibility where fog forms.

People setting out early may also need extra time to clear frost from vehicles.

Nationally, forecasters expect the UK to feel markedly colder from Thursday through Saturday, with frosty nights and plenty of autumn sunshine for many places.

Wintry showers are chiefly forecast for the far north rather than West Wales.

The Met Office has challenged dramatic claims of an approaching Arctic freeze and snow blanketing dozens of counties.

Its current outlook does not indicate a widespread or particularly significant cold spell.

For West Wales, frost and fog are more credible concerns than disruptive snowfall.

Drivers should allow extra time for journeys and take care on untreated roads, especially where visibility falls.

The cold, dry spell is unlikely to last particularly long.

The longer-range forecast covering Sunday, November 15 to Tuesday, November 24 points to a return to unsettled Atlantic weather.

Areas of low pressure are expected to bring periods of rain and stronger winds, broken up by brighter and showery spells.

The Met Office says the period is likely to be wetter than average for much of the UK.

Although colder episodes remain possible, temperatures are expected to be near or slightly above the seasonal average for much of that period.

West Wales is therefore preparing for a sharp but relatively brief cold snap, with frosty mornings and localised fog the main concerns before wetter Atlantic conditions return.
