North West Regional Discussion 30 December 2020 onwards

[damianslaw]

Greens and Pinks over the Lake District, evidence colder air has made it. Just rain here at present temp of 3 degrees though radar shows green. Low cloud so not able to see where the current snowline is, suspect around 300m. Need heavier precipitation to cool temps to a more optimum temp for snow at low levels, however, the heaviest stuff looks further south over Yorkshire and there is only moderate rates aloft to the north. One of those set ups again where you need very heavy precipitation to enable evaporative cooling to turn rain to snow at low levels. This is turning into a case of so many near misses this season. Alas there is time for something wintry in the next few hours, but best we can hope for is a slight slushy cover, which doesn't do it for me, might as well just stay as rain. A day of rain and temps 2-3 degrees is a kick in the teeth really.. might as well be 10 degrees. Fells will be getting a new coat at least.

Next few days don't hold much promise of any snow cover, so attention turns later into next week.

Slowly but surely the splodge of raindrop on the window is being replaced by the tinkle of ice. Even if this changes to full on snow the ground is so wet I can't see it sticking. 

If the Dew points is low enough and the precipitation heavy enough then it sticks regardless of how wet the ground is.

[PennineMark]

Full on snow now and temp now below 0.5c. And weirdly enough it is readily settling.

The hill to around 300m between myself and Stalybridge has started to turn white and down at 150m its gone quite sleety.

Sleet falling on skylight in hattersley,  met office snow warning moved west to cover more of the region too

Yeah frontal intensity, daytime warming are factors against us not that I thought there was much potential right down here but I thought Windermere may have a better chance though. 

The uppers are forecast to get a little colder as the day goes on but wrong time of day really, factors against us. Still I would not give up fully in your location and you just never know.

Ice pellets and snow flakes.

Certainly was . The magic of meteorological physics ❄

[janmac]

The rain (that doesn't seem to have stopped all night) has turned into ice pellets in East Lancs! 

[raul_sbd]

3.7c and 3.1c DP here in Costa del Sale.. drying up a bit which made the RH to come down to 96% on the right direction the DPs maybe to see some sleet later on..

Give it another hour for that inversion to mix out above you and it will be proper snow all the way.

Nice steady sleet/snow here now

[severe snowstorm]

The biggest issue in Westernmost parts is probably more whether there will be any decent precipitation left in these parts by the time it gets cold enough for snow.

But never a problem when the rain arrives. Copious amounts all the way lol.

The ice pellets hitting the window are no longer melting straight away... And I can see snowflakes! Hubby is working in Waterfoot and, I quote, "it's humping it down!"

[Mountain Snow]

Has been snowing steadily for a few hours now but only just now starting to give all surfaces a good cover. Love how the world goes from green to white in what seems like a few minutes!
