There is a chill in the air again today and it was certainly cold in Mid Wales.
Last night at Tirabad in Powys, the temperature dropped to -4 Celsius, 25 Fahrenheit - making it the coldest May night there since 1996!
Gardeners need to be on their guard again tonight because more frost is expected.
Tomorrow night, though, will be different; cloudy and milder with outbreaks of rain.
And then over the weekend, some ground frost is likely in places but next week will become warmer with south-westerly winds.
