Today it was either gloriously sunny, or overcast with little in the way, but through the evening the cloud reforms in many places. Tonight, more cloud begins to build but there will be enough breaks in the cloud to allow temperatures to get down to freezing, expect a widespread frost.
Monday starts mainly cloudy, but it will already be brighter in the west. As the day progresses the sun will break through the cloud and everywhere should see some good sunny spells. Highs of 9C but still feeling rather cool.
There's more bright weather around for Tuesday and it will be much milder too with highs of 11C. Midweek sees a weak warm front drifting over Wales bringing light rain and drizzle, with more showery rain expected on Thursday.
