The Met Office has been looking into the possibility of a "beast from the east" weather system striking the UK as temperatures have started to drop again. Cold weather is expected for much of the rest of this week and there is a possibility of snow in some parts of the country by Wednesday next week.
Parts of Mid Wales hit -1C overnight, with temperatures expected to drop to 0C across the country in the early hours of Friday morning. Looking at the Met Office weather map, temperatures are forecast to be around freezing in parts of the country on Sunday night.
But the real cold spell is expected to hit later in March, and the outlook from March 9 to March 23 says: "In this period, spells of rain or snow, are more likely than earlier in the month, with a low chance that some wintry episodes could be disruptive, though northwestern areas most likely to see the driest conditions. Winds could often be from a northerly or easterly direction, and temperatures are more likely to be below-average than above-average overall, but later in the month, colder air will be fighting against a strengthening sun."
