UPDATED: Prepare for snow Deeside – Met Office issues a yellow weather alert

The Met Office has changed the weather warning:

Weather alert cancelled for Wednesday – but snow warning remains in place for Thursday and Friday

Temperatures are set to take a significant dip this week as an Arctic air brings snow to many parts of the UK.

Strongs winds and snow showers are expected to develop from Wednesday evening lasting into Thursday.

The Met Office has issued a yellow ‘Be Alert” warning for Flintshire as snow COULD lead to very poor travel conditions locally.

Chief Forecaster’s assessment:

Cold air originating over Arctic Canada will affect the area from Wednesday evening through Thursday, bringing snow showers and strong winds. Wind gusts up to 55 mph are expected in exposed coastal areas and on hills in association with snow showers, leading to temporary blizzard conditions.

As well as reduced visibility, 2-5 cm of snow could accumulate anywhere within the warning area, with 10-20 cm possible above 300 m.

Lightning may accompany the heaviest showers, with potential disruption to power supplies as a consequence
