A spell of colder weather is set to move into North Wales this week, bringing a noticeable change after recent mild conditions.
According to the Met Office, conditions across Conwy County and the wider North Wales area will turn sharply colder from Tuesday, as heavy rain moves through before being replaced by brisk north-westerly winds.
By Wednesday, temperatures are expected to drop significantly, bringing a mix of sunshine and blustery showers — some of which could turn wintry, particularly over higher ground. Snow is most likely on the hills and mountains, including Eryri, where forecasters say a covering of up to 5cm is possible on the peaks.
At lower levels, including coastal areas such as Llandudno, Colwyn Bay and Rhyl, the likelihood of settling snow remains low. However, the Met Office says there is still a chance of brief sleet or wet snow showers, especially during heavier bursts, though these are unlikely to accumulate.
The coldest conditions are expected on Wednesday into Thursday morning, with overnight frosts and icy patches developing widely. Temperatures on the highest ground could feel as low as minus 10 degrees Celsius in strong winds.
Looking ahead to Thursday, it will stay cold with a widespread frost early on, followed by brighter spells and the risk of further scattered wintry showers.
The sudden change comes after parts of Wales recently saw temperatures close to 20°C — making this return to near-freezing conditions feel particularly stark.
The Met Office is advising people to stay up to date with the latest forecasts, as conditions can change quickly — particularly when it comes to snow risk.
