It was a chilly day today with a few showers around and it will be a chilly night tonight. Temperatures drop to around zero in many places, any showers could fall on cold surfaces to cause icy patches on untreated roads and pavements. Later on some more showers arrive in the north. These are likely to be wintry in nature, even at lower levels.
There is cold air behind the showers but clearer weather too. Some lovely winter sunshine for Wednesday but again more showers which could be wintry. It will feel even colder than today.
Thursday could be a rather interesting day. A low pressure system is expected to bring a spell of wet weather but because it's coming up against cold air, it may well fall as snow. And significant amounts, possibly at lower levels too.
