Britain is bracing for an abrupt return to freezing conditions later this month, as weather maps predict a sharp drop in temperatures, with some regions plunging to -1C. The latest forecast data from WXCharts reveals a snapshot of the chill set to grip the UK by Wednesday, April 23, at 6am.

Despite recent spring warmth, the maps show a swathe of the country waking up to freezing or near-freezing temperatures, particularly across inland and rural areas. This "arctic blast" could see frost forming in several locations, a stark contrast to the milder start to April.

According to WXCharts data, the following regions are expected to experience minimum temperatures of freezing (0°C) or below:

Central and Northern England:

• Midlands
• Peak District
• Lincolnshire
• Yorkshire Dales

Wales:

• Brecon Beacons
• Snowdonia
• Central Welsh uplands

Northern Ireland:

• Counties Tyrone, Fermanagh and Armagh

Scotland:

• Central Highlands
• Grampians
• Borders region

South-West England:

East Anglia and Surrounding Areas:

• Parts of Norfolk and Suffolk

These areas are shown in light blue and white shades on the WXCharts map, indicating temperatures ranging from -1°C to 0°C. Localised frost and chilly dawns are expected, particularly in sheltered rural spots.

While WXCharts suggests a widespread cold snap, the Met Office says otherwise. In their latest outlook from April 17 to 26, forecasters said: “Much more mixed weather conditions than of late, with low pressure systems and their associated areas of rain and showers often affecting the UK.

"Gusty winds, risk of hail and thunder, and large amounts of cloud are expected. Temperatures will probably be close to the average or slightly above for the time of year.”

Later in the period, the Met Office does acknowledge a potential shift toward “more settled, drier but perhaps cooler weather."

While a brief Arctic dip may indeed hit parts of the country next week, most areas are still likely to experience a mixed bag of weather, from chilly mornings to rain-soaked afternoons and the odd sunny spell.
