7cm in the end in favoured spots (grass, cars) more than the previous event, well forecast here… Not so much for the met office 😂

[Kasim Awan]

Thanks for the comments.

Chris did a good job.

I think the snow map verified quite well, maybe a slight underestimation. What I’m interested in is did the cut off point of runcorn / Liverpool for the main snow area verify?

Well done Kasim and Chris 3-4 inches of snow here… still coming down… we’ll done 👍👌❄️❄️❄️❄️

[Chris in Bramley, Rotherham]

Snowing in Rotherham now! Started to settle on cars and grass. Amazing transition. Temp here went from 9c to 0.5c in less than 2 hours.
Shame it’s at night and I can’t watch lol!

Some marginal wintry showers. I’m taking a few days off. Might check in a few times but will be back on Friday night ready for the weekend’s interest.

I would love to know why exactly snow was so widespread when temperatures were only around 2c at lower levels, was it the intensity? The fact is was a frontal feature? Etc.

Snow here at 1.30 am in EAst Yorkshire at only 50 m asl ( and beginning to settle on cars and grass )

[Jeremy S]

Just like others the temp went from 10 c at 11pm to 0.8 c at 1.30 am .. remarkable

[SouthYorks]

Other than a couple of moderate snow showers starting around 11pm, we had nothing overnight. Somehow the whole band of snow missed South Yorkshire seemingly skipping from the Pennines to East Yorkshire!

[Weather Enthusiast]

About 1cm on grass and none on roads or pavements here in Queensbury. Turned to snow around 10:15pm but the intensity was less than further south west, so on this occasion elevation didn’t help. No further over night and rain showers this morning.

The intensity means it takes longer for the snow to melt. As a result it falls further from the freezing line than light snow would given the same dew point etc. Light winds also helped and cold air aloft increased the lapse rate meaning the slice of >0C air was only quite short.

Potential for a streamer within fairly conducive conditions tomorrow night. Tonight lacks much interest.
