It was a dry St. David's day across much of Wales yesterday although it wasn't sunny everywhere and like today, many places woke up to fog making for some tricky driving conditions during rush hour.

Last week we were shivering with cold easterly winds from Russia but this week it's a different story.
High pressure over the Atlantic means north-westerly winds for the UK so it's going to be milder than recently with temperatures staying above freezing.

Much of Wales has had a wintry mixture of rain, sleet and snow over the last 24 hours, with most of the snow falling on higher ground.
