Spring versus winter – the battle continues
Yesterday, I was passing through suburban west London on the train and one thing really stood out as I looked across the landscape. The trees are still bare. Not a blossom in sight.
I can’t remember the last time that trees lacked foliage so late into March – especially in London where the urban warmth normally spurs the buds to life even when a slight spring chill lingers in the air.
I took to Twitter to ask people across the UK whether they were experiencing the same lack of plant growth. Alas, responses were laden with struggling daffodils and shoots that were only just managing to get above ground.
Despite a very brief burst of warmth around ten days ago, much of March has seen a continuation of wintry weather.
Further snowfalls have blanketed the normally green landscape, hard frosts have frozen the ground solid and there’s been wind chill more akin to mid-January.
As I explained in my blog last week, the jet stream is unusually far south at the moment – over Iberia and northern Africa when it should be across Scotland and Scandinavia.
The result of this has been cold air sitting persistently over much of western Europe, keeping us firmly within winter’s icy grip.
What can be expected this week?
This week, the UK is going to be the battle ground between winter and spring, with milder air sitting to the south west and colder air lurking to the north east.
During the next five days, the colder air is going to have the upper hand, with the coldest weather across Scotland, Northern Ireland and northern parts of England.
In these areas, further heavy snow is likely at times – especially for eastern Scotland and north east England (mainly north of the Humber), where 5-10cm could fall at low levels and 10-20cm over the hills and mountains.
Adding to this will be the effect of a brisk and raw easterly wind, drifting the snow around giving poor visibility.
For the rest of England, along with Wales, whilst chilly, it won’t be as cold as further north. However, heavier showers could still be wintry at times with a covering of snow possible – mainly overnight when it’s colder.
When will it get warmer?
As a result, it would bring warmer air in off the Atlantic and push winter across the North Sea into Scandinavia, with temperatures closer to average at 8-12C.
This would mean that rain would be more likely than snow and night frosts become less likely.
However, the caveat is that winter will still lurk relatively near by with the chance that it could pounce back at any time.
