Feeling bitterly cold at present with a slightly different set up to the first time the "Beast from the East" came to bite us. High pressure is over Scandinavia promoting the E/SE flow. As the air blows across the North Sea it picks up showers BUT it doesn't come from as far east as last time, so it won't feel quite as cold as a couple of weeks ago, and it won't last as long with a return to milder air and more average temperatures for the time of year by Wednesday of the new week.
Wind chill is a big factor on Saturday. On Friday, we were into positive double figures, up to just shy of 11c in parts of Yorkshire...but today, Saturday, feels more like minus 8 or minus 9c in the wind.
Throughout Saturday, the wind begins to ease but as it does, the snow showers are likely to start banding together and become more prolonged. The snow is dry and powdery so there will be lots of drifting and poor visibility, and even though winds ease, we still expect gusts of 35-40mph on Saturday evening and overnight, so take extra care if you need to traverse higher routes, especially Pennine routes.
Saturday night into Sunday morning is a key period of concern. 5-10cm snow possible to lower levels, with up to 15cm / 6 inches over higher ground. With strong easterly winds and powdery snow, drifting is likely and could cause considerable disruption.
The snow showers continue throughout Sunday, with an increased chance that longer spells of snow will affect some areas. However, snow showers become more isolated on Sunday.
Risk of snow and ice everywhere on Saturday night into Sunday, bitterly cold with a penetrating frost.
Winter continues unabated and the following Amber weather warnings have been issued by the Met Office.
Amber "Be Prepared" Warning for snow and ice - valid: 16:00 Saturday 17th March until 09:00 Sunday 18th March 2018
Snow showers are expected to become more frequent through Saturday evening and night with icy patches also developing on some untreated roads, pavements and cycle paths. Strong easterly winds will lead to some temporary blizzard conditions and drifting of snow. Travel delays on roads are likely, stranding some vehicles and passengers. Some delays and cancellations to rail and air travel are likely. There is a chance that some rural communities will be cut off. Some injuries from slips and falls on icy surfaces are expected.
Snow accumulations will be variable across the area as showers are expected to organise into bands. Whilst some areas will receive relatively small amounts of snow, narrow bands of 5-10 cm of snow are likely, with a chance of 15 cm over higher ground. Strong easterly winds will result in some drifting of lying snow, and lead to a significant wind chill. Showers are expected to become more isolated through Sunday morning.
Amber "Be Prepared" snow warning - valid 00:05 Sunday 18th March until 21:00 Sunday 18th March
A spell of snow will move west across many parts of southwest Britain on Saturday night and Sunday. Snow will turn heavy in places on Sunday, and may last for much of the day across parts of southwest England. Strong east or northeasterly winds will lead to some drifting of snow, especially over hills, with significant wind chill. Travel delays on roads are likely, stranding some vehicles and passengers. Delays and cancellations to rail and air travel are likely. There is a good chance that some rural upland communities could become cut off. Disruption to power supplies is possible, especially in parts of southwest England, due to wet snow bringing down branches or other structures. The warning has been extended west across Cornwall, and also until 2100; this later clearance most likely in the far southwest.
