Brief Cold spell today and tomorrow but then a very mild week

A band of heavy rain and gusty winds is currently moving SE across the UK and this should clear most parts by late afternoon but maybe not until late evening in the South East. Behind this is much colder air which will bring snow/sleet/hail showers to Scotland, Northern Ireland, North West England and parts of North and West Wales. When the front has passed through, temperatures will plummet from around 8-10c to 3-5c in many parts with a biting North Westerly Wind with a very cold wind chill. So today will bring a wet day for many and windy too and cold in the north from early morning but the cold doesn't reach the South until late afternoon/evening. Once the front clears, wintry showers across Scot, N.I, NW England and N & W Wales but mainly dry and clear elsewhere and a widespread frost tonight. Max Temperatures Today - 4/5c North, 8/9c South but 3-5c once front has passed through. Low Tonight generally 0c to -3c but probably above freezing in any coastal areas. If anyone has a weather station, the temperature drop today will be huge and quite quick aswell. The temperature has dropped 2c in 35 minutes here.

For Pembrokeshire, showers of hail/sleet/snow will affect the county for the early part of tonight and may lead to icy stretches first thing tomorrow. Tomorrow will be sunny but windy and cold with a max temperature of 7c. 

The radar picture below highlights the front moving through with the wintry showers following behind. The other charts below show the huge difference in surface temperature once the front moves through. (Click on the charts to expand them)

                                Saturday 15:00
                                Saturday 21:00

Sunday will then bring a sunny cold winters day to many after an early frost and any wintry showers will die out during the die but staying cold with a strong NW wind with a Real feel of around -5/-6c. Another Frost in central and Eastern areas tonight.

Next week is all change again with very mild and mainly unsettled conditions affecting much of the country. Highs could reach 15c in the south by the end of the week.
