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.
