Today is a transitional day as much colder weather arrives for the rest of the week with widepread frosts, icy roads and some snow in the forecast.
This afternoon a band of rain clears south eastwards to leave scattered showers and some brighter spells.
It's a cold front though, so colder conditions will follow it with temperatures dropping to single figures and highs of between 7 to 10℃.
Tonight, we're into much colder air so any showers could be wintry, falling as snow in Snowdonia, the Cambrian mountains, Brecon Beacons and in higher communities.
The Met Office is advising that ice could be a widespread problem as temperatures fall around freezing overnight.
So, first thing on Tuesday morning we'll see an early frost and ice with some slippery surfaces followed by plenty of sunny spells, especially further east.
The west will experience a few showers, again wintry on higher ground with a brisk northerly wind bringing in Arctic air on Tueday.
Temperatures will remain low with highs of just 4℃ in North Powys and 7℃ in Conwy but the wind chill will make it feel much colder.
On Tuesday night and into Wednesday morning, another weather system pushes in from the north west, bringing a mix of rain, sleet and some snow on higher ground.
Wednesday morning will start wet and windy with any early rain clearing to showers.
It will be fairly overcast, not quite as cold as Tuesday but with much stronger north westerly winds, possibly reaching gale force on the coast.
Thursday will be a brighter, breezier day, with some sunshine and the odd wintry shower.
High pressure will be building again later in the week bringing more settled weather but also colder conditions and more widespread frosts.
