Saint Snow
17 January 2015 22:23:04


Finally having a wet snow shower that started as hail. Not holding my breath as the next shower could be anything, but there's a slushy dusting at least! Think unfortunately the 850s are just a degree or two too high for a good setup close to the coast. Could be quite impressive further east though looking at the radar.

We struck lucky on Boxing Day with conditions aloft not that dissimilar.


 


EDIT: the 850's here are supposed to have been around -6c for most the day, so I'm not sure what the issue is. Anyone?

On the plus side, convection over the Irish Sea still looks active and, with temps falling, we may just get a snow shower or two before the night's out.


Although probably not

I know you've had a few streamers that have delivered over your way in the past but I really can't remember anything other than that icy/slushy covering from Irish Sea showers around here. I'd love to see a polar low make a visit one day but I'm starting to think they're just an urban legend!


Winds are definitely helping shift the showers down a bit further south now but they're still largely heading into the Lancs Plain and into GTM.

Been waiting all day for the wind to shift more WNW and it's finally delivering with the streamer off the Irish sea making it this far.
Moderate snow falling and settling here in sheffield.

The high-res radar shows the shower train along the M62 nicely, with snow falling Oldham to Sheffield for the last 90 minutes.
Also the area in N Scotland is moving in and expanding and it's pretty much all snow.
Rain showers in the South.

The lane is rather slushy here, if that snow freezes over it will be a hazard by morning

Another top up, big huge flakes too  could be one of the last of the night looking at the radar.

Is that large area of heavy ppn pushing through Wiltshire into Berkshire now anything other than rain?

The period of rain from that weather front on the northerly flow has now cleared. Might see some sleet later?

At last proper snow in north Cumbria courtesy of a narrow through moving south from Scotland.


with a temperature of -1.7c the snow is dry and pure, non of that sleeting stuff so everything has gone white.


More coming out of Scotland on the radar, not a blizzard but for once someone has taken the fuse out of the Penrith snow shield.

Got a meeting in Inverness on Tuesday so looking forward to some good views as I travel north, I think I have to go through Aviemore but not sure, either way it's a 5am start!


I love my visits to Scotland the people are so friendly, I thinking coming from Cumbria they regard me as part Scottish anyway lol.

It has been 2 years since we have had measurable snow here Andy.

I think it may have snowed for a few minutes in the middle of the night before changing to rain. Wouldn't surprise me if there was nothing but rain today (as that is what the raw model output shows).

Hoping we can get some more snow from that band moving out of the far north of England that seems to be delivering the goods for Cumbria. Problem is that it may break up and if arrrives too near the middle of the day as patchy stuff it might be too warm. -3.0c currently.

Look like it's been drizzly here, but not much falling from the sky at the moment so cannot verify whether or not it had a wintry flavour.

Yeah had a look at my weather app overnight - it showed the forecast was 1C and snow, but gave the actual temp as 4C and drizzle. Something went wrong somewhere!

Yes the moist plume aloft mixed to shallower levels and raised surface WB and dp above 0. Lighter ppn didn't bond and therefore readily melted on it's way into air which is above freezing and not able to support snow. There was a bit around early hours but I didn't see it.
For these very marginal set-ups you really need heavy ppn so that evaporative cooling can swing the pendulum. I've seen drizzle at 0C and heavy snow at 4C (to start) in the evap cooling set-ups.
