As many of you will have read, Scotland has recently been hit by snow and the cold snap is heading our way.
Arctic winds will be bringing a big drop in temperature.
March was the warmest month in Wales since 1957 with beach and picnic weather last week and highs of 22 Celsius but tomorrow, temperatures will struggle to reach 4 Celsius in places.
Wales is facing a wintry mix of rain and snow over the next 24 hours and strong to gale force north-easterly winds will make it feel bitterly cold with a significant wind-chill.
The Met Office has issued a weather warning but not everywhere will have snow and most will fall on higher ground, over the hills and mountains above 600 feet. Typically 2-5cm is expected but 10-15cm is possible above 1000 feet.
This could cause a few problems on the higher routes with blizzards on the mountains. The hills of Powys, the Brecon Beacons and Black mountains could get a fair covering of snow tomorrow but at lower levels and on the coast, rain or sleet is more likely.
Snow is not unusual in April. In fact it's more common to have a white Easter than a white Christmas but the cold snap will come as a shock to the system given how unusually warm March was.
Some plants, trees, animals and wildlife are likely to suffer but thankfully the cold snap will be short-lived.
Tomorrow night the rain and snow will turn lighter and slowly clear with some frost and icy patches developing. Thursday will be a much better day - drier and brighter with sunny spells with lighter winds so it will feel less cold.
At the moment, Easter weekend looks milder and changeable. Some rain and a few showers but we could see some dry weather and sunshine too. In other words, a typical bank holiday weekend in Britain!
