After a non-winter, all of a sudden old man winter gets here 3 months late and doesn’t want to leave. A +AO/NAO low pressure dominated winter has abruptly flipped to a -AO/NAO high pressure dominated spring.
We’ve went from 200% of normal rainfall widely back in February to just 20% of normal rain during April.

A simple wind shift and you go from June to March within 24 hours.
What a difference a windshift can do to maximum temps over south/east England in mid April. Highs Easter Sunday vs Easter Monday! pic.twitter.com/4RW0fNsZ0x

Big Diurnal Swing
The drying out of the soil beneath a blocking high and in a landlocked location has led to big diurnal temperature swings, especially beneath the core over eastern Scotland.
Near stationary front and associated cloud has made quite the temp contest over Scotland. 6C Loch Glascarnoch vs 17C at Charterhall. Inverness 7 vs 15 just 25 miles away at Aviemore. pic.twitter.com/a8xxVR4c1l

Coldest since May 1997? So what happened then?
With a cold plunge of Arctic air arriving this weekend, I thought I'd look back in the Met Office archives for previous cold May days with snowfall…
On 6th May 1997, over 200 weather stations in the UK reported falling snow.
Halkyn in North Wales had 15cm of lying snow! pic.twitter.com/OlyzvmhAj9
