We enjoyed a fine weekend across most of Wales - the first one after the spring equinox and it felt like it, with plenty of spring sunshine.
There's a much more unsettled week to come though - cooler, often cloudier, with some sunshine, but wet and windy at times.

Monday afternoon is rather cloudy with some patchy drizzle clearing south-eastwards. It will eventually turn a bit brighter from the north-west later, with highs of 8-10°C with a chilly north-westerly breeze.
Tonight, there will be a few lingering showers but will generally turn clearer and colder with some frost patches forming overnight.
Tuesday is a changeable day - with scattered showers, some quite sharp hail and thunder, possibly feeling wintry in the hills, with sunny spells in-between and variable cloud. Temperatures will be slightly lower than recent days at 7 or 8°C - with brisk north-westerly winds making it feel chilly.
Showers will slowly ease on Tuesday night. High pressure will build, with clearer skies and lighter winds, temperatures will drop away - so there will be some frost patches forming overnight, away from the north and west coast.
Wednesday is probably the driest, brightest day of the week with lighter winds and decent sunny spells - but it could turn wet and windy later on Wednesday and overnight into Thursday, potentially with some snow on high ground.
Rain should clear by early Thursday, turning brighter and breezy later. However, there's further rain in the forecast on Friday, with winds picking up too.
So it's a very changeable week! It will be colder than the last few days, and although we're officially into spring, we'll still see some frost by night.
