Thursday 1st March 2018 – Sunday 4th March 2018

Hi all,

Thursday sees a change of season in the Weather World. Spring has sprung! Well not quite! Although our winter ends today [Wednesday], the weather has gone back in time, as the much-promised Beast From the East arrived bringing snow, tumbling temperatures and a severe wind-chill this week. So when will it all end? In fact, when will we get above freezing again?

Thursday: Like yesterday, one of the coldest days for years. An extreme wind-chill making it feel like -12°C. A mostly cloudy day, there could be some brightness from time-to-time, but equally some more snow showers. These should ease later. Winds strong, gusting to 40mph. Max -2°C

Friday: Bright spells and a few snow flurries. Then later in the day, the forecast is not set in stone, but there is a risk of some snow coming up from the south-west, accompanied by a strong south-easterly wind making it feel like -10°C and gusting to 45mph. As I say, the track of the low pressure, which has been named Storm Emma by the Portuguese Weather Centre, is uncertain, so the snow event might not happen and this is confirmed by the GIF below. The snow tries its best to arrive across the region towards the evening, but fizzles out. The forecast could change so watch out for tweets. Max 0°C

Snow on Friday

Heavy snow will cause disruption in southwestern parts of the UK but will it make it here

Weekend: Still very cold but less so into Sunday. Some snow.

Saturday: Still Baltic but not as windy as Friday. Cloudy with some snow flurries then perhaps a spell of snow for a few hours. Max 1°C

Sunday: Less cold air will push across the region which will recover the temperatures a little and after days of sub-zero values, we will sneak above 0°C. Again, mostly cloudy with a cold wind and the potential is there for some snow showers. Still very cold. Max 3°C

Outlook: Remaining colder-than-average with some wintry showers, so the risk of some snow remains. No sign of our first taste of spring. Don’t thank me, thank Sudden Stratospheric Warming. 

A huge thank you for all your photos, road updates and interactions this week.

Bitter Cold and Snow Update

Hi all,

Just a ‘quick’ blog to keep you updated on the up-and-coming coldest weather for years.

The Met Office have issued a Level 3 Cold Weather Alert for this week. This is one short of a National Emergency. This highlights the severity of this week’s cold.

Cold Weather Alert

For the past few days we have been dragging in cold air from the east (as mentioned in last week’s blog) but during this week, even colder air (aka The Beast From The East) will filter westwards all the way from Siberia, with some extreme wind-chill values for the UK. As this air comes across the relatively warmer North Sea, it will develop snow showers which will be heavy and possibly thundery. The strength of the wind will move them well inland.

The bitter weather is set to last all week with some uncertainty from Friday. During Thursday night into Friday it looks like a low pressure will come up from the south. This is going to bring widespread snow and blizzards to southern parts of England and Wales. It’s too early to say how far north this will come but there is a chance we will see some snowfall from it. After that milder air will try to arrive from the south-west but it might not succeed, or, if it does, it’ll take several days for temperatures to recover. One thing that seems certain this week is that there will be some significant and disruptive snowfall for parts of the UK.

Snow: I’m expecting all of us to see snow at some point over the week. There won’t be any rain falling, anything that falls will be snow, even to sea-level as it will be so cold. The snow showers could easily bring 3-5cm for most of us, with the chance of 10-15cm over the Pennines and surrounding hills as they take a direct hit from the showers firing in on a, at times, gale-force gusting easterly wind. Warnings are in place and more could follow.

Snow Tuesday morning

Snow showers will start to feed in from the NE in the early hours of Tuesday morning

Temperatures: Daytime highs will struggle above freezing and are expected to remain below freezing on Wednesday and Thursday at least. There will be hard penetrating frosts all week with lows down to -7°C, and -10°C in rural spots, especially over snow-cover.

Weds Maximums

Wednesday’s maximums – add on the wind and it will be Baltic

Wind-chill: All week the wind-chill will be sub-zero and midweek it is likely to start to feel like -12°C or lower.

 

Severe Windchill Thursday AM

Severe wind-chill this week – values as low as -12°C to -14°C in places by Thursday

Sunday: Sunny spells but feeling cold in the wind. Remaining dry. Max 4°C

Monday: The much colder air has arrived and with it more cloud than recent days. Sunny spells, a biting wind and perhaps some snow flurries later in the day. Max 2°C

Tuesday: During the early hours and into the morning there is a risk of some prolonged snow arriving from the NE, especially so in eastern parts. After this clears it’s a day of bright spells and scattered snow showers. Feeling very cold with a -7°C wind-chill. Max 1°C

Wednesday: A bitterly cold day with frequent snow showers from the east filtering well inland. Heaviest of the showers in eastern areas. Some of the showers could be thundery and there will be drifting of any lying snow as winds gust 30mph. Max 0°C

Thursday: Mostly cloudy, some light snow showers but there should be less than yesterday. Severe wind-chill (-12°C) and the coldest day for years. Max -1°C

Snow Event Friday

A significant snow event looks possible next Friday which will cause disruption

Friday: Much uncertainty but likely to be cloudy, freezing cold with light snow arriving from the south. It will also be very windy with 40mph gusts. Again wind-chill values down to -10°C or lower. Further updates during the week. Max 0°C

Just to note: Snowfall is difficult to predict when it arrives in the form of showers. Some areas will see a lot more snow than others as showers produce localised amounts.
