This Evening and Tonight:
Very cold with a brisk and bitter easterly breeze and temperatures falling quickly below freezing. Scattered snow showers will develop giving slight accumulations by daybreak in the east but more isolated in the west. Minimum Temperature -3C.
Further scattered snow showers, mainly in the east, will be interspersed with some bright or sunny intervals. It will feel very cold with a brisk and bitter easterly breeze. Maximum Temperature 2C.
Outlook for Tuesday to Thursday:
Bitterly cold, becoming windy with penetrating night frosts. Occasional heavy snow showers in the east giving locally significant accumulations on Tuesday, less frequent Wednesday. Perhaps heavy snow later on Thursday.
Day 6 to 15
Northern areas will be bright with further snow showers on Friday, but we could see heavier and disruptive snow developing across southern and some central areas, combined with strong to gale force easterly winds, leading to blizzard conditions. However, there is a an element of uncertainty with this. Thereafter, it is looking increasingly likely to be unsettled with a north-south split in temperatures across the UK. The coldest and driest conditions are likely in the far north and northwest. We may see areas of rain moving northeastwards from the southwest at times, which could well turn to snow across central and northern areas. It will be often windy with gales possible at times. Remaining cold for many, but nearer normal temperatures at times in the southern half of the UK.
Day 16 to 30
A blocked pattern remains most likely across much of the UK, with colder than average conditions, but possibly milder at times in the south and southwest. Further bitterly cold easterly winds are probable, giving a significant wind chill. There will continue to be a risk of snow across some central and northern areas, but in the far north and northwest it should be drier. Frosts will continue to be widespread and severe in places. As we head towards the middle of March it may turn more unsettled and less cold with milder and wetter weather spreading up from the south or southwest. This may lead to further significant snow in places although this remains very uncertain. Northern areas may hang on to the colder weather well into March.
