Would love that band of precipitation over Cumbria and County Durham to maintain its intensity and give us a covering as it pushes south. Unfortunately most of the modelling breaks it up and fragments it.
-
Some light snow very early this morning but nothing substantial.
Moors look white above about 300m past Bradford.

My Grandma lived at Woodford, remember I was concerned with how cold it got there. Might have been Jan 10 it had the lowest temps?

High ground over here can be cold though. As well as lower ground. Shap sits at 249m and got down to -11c last Dec and -18c in Dec 2010. Interesting how that's often not the case on the other side of the hills.
Yep Shap is a good frost hollow. Often beats anywhere else in England for overnight temps. It is in a bit of a valley though with 300m asl ground on most sides so the cold air can drain and get trapped at Shap. At LBA the cold air cannot sit as it drains down on 3/4 sides down to 70-100m asl. More about the geography and shelter rather than strictly elevation .

More to do with intensity. I noticed on the radar a lot of yellows and even some speckles of oranges (heavy stuff) over that side but over this side more greens (much lighter). It's generally not any colder over that side, in fact under cold clear conditions it's far colder this side for some reason. If you look at the December cold spell on the below graphs that I've attached it shows Manchester airport was much colder than Leeds/Bradford airport and that's often the case during our harshest winter spells, we got down to -10c and Leeds was barely scraping -5c. I remember those on this forum east of the hills moaning how they wasn't as cold as us. This was the same in 2010 too, plenty of dark blues this side of the hills but lighter blues over the other side.
Manchester
Leeds
I generally agree with you that the NW seems to be slightly colder overnight in many cold spell situations but I wouldn't use Leeds/Bradford as the comparison as that makes the difference seem more than it is. LBA is 210masl at the top of a hill so cannot get low overnight temps as nowhere for the cold to drain from. Like LBA I have never recorded a temp below -9c back to 1994 as I am similarly placed but it can be and is much colder in the valleys and Vale of York. Places like Church Fenton and Linton on ooze .
As an example it was -15c for two nights at Linton on ooze (York) in Dec 2010 but on the same nights -9c and -7c at LBA

Heavy snow , an extra cm cover so far. Settled on the road no problem.

Heavy snow here now 0.5c and dropping. Settling on raised surfaces and obviously the existing snow cover but also starting to lay on the cleared drive.
-
Some melt today, inevitable in the March sunshine but still looking great now as the temp drops below freezing again.

Lots of snow in the night. There was 9cm when went to bed and now average measurement of 21cm on grass and patio. Lots of variation due to the wind though.

Pic is taken on night setting so light is exaggerated but always love how it isn't dark outside due to the orange glow and snow on nights like this.

It's about to really ramp up soon for you lot NW leeds, can tell from radar!
Does seem heavier now.
Would have bit your hand off for this last week, it is a good snow event, just probably not an amber warning for here at the moment. Amber warning for me is heavy snowfall probably during the daytime too that cuts an area off like 8 and 15 Jan 2021 should have been here.

Measured average of 9cm here , as others have said it's building up really slowly though at the moment.

Hmmmmm since 3pm we've probably had about 3cm.
I'm feeling a touch less optimistic than I was earlier.
Seems a bit heavier now and more greens on the radar.
-
No temp issues here now as -0.3c and full snow cover . Steady fine snow building up, but would prefer it to be a bit heavier if we are to get some special totals.
Heavier pulses are appearing spreading from Harrogate, so hopefully that is the orographic effect kicking in. Not really possible to track much radar wise anymore, seems to all develop in situ and be quite static apart from the stuff moving up towards S Yorks. A complicated picture.

Horsforth train station is a different world from here at 110m asl, proper snow line about 150m now, everything covered above that.
-
Decent heavy snow and temp down to 0.0c.
Starting to lay on the road for the first time today

Good to hear positive reports further south, Back to sleety rain now in North Leeds with a temp and dew of 1c. Heavier stuff should hopefully land within the hour. Fingers crossed!
Lets hope so, it has gone darker. 0.7c here with drip drip but that stuff to the South looks very interesting...perhaps it will cause rush hour carnage. A know a number of people who think that it is and have started venturing out. Lets face it drip drip normally means the end of a snow event but not today.
-
The temp has risen a bit to 0.5c and there is some dripping now, but it isn't really because milder air has come up from the South (still 1c across the Midlands) but because the snow has gone very light and it is the middle of the day in March.
March 22 2013, there was a lot more snow on all surfaces, but there was a period for an hour or so in the middle of the event when it starting slowly thawing even at 200m, then it re-froze and everything was lethal. Don't really want to compare the events but March daylight is always an issue.

5cm on patio, maybe a bit more on grass. Same with trees , soil and raised surfaces .
Strangely some bits of pavement have a good depth and others are completely wet and bare.

12.16 is the time the sun is the highest, so daylight should diminish from now on, hopefully helping marginal conditions.

Heavier snow now at 0.0c.
Road still clear , cover gradually increasing on pavements and drives but remains patchy.

So it’s meant to ramp up later? This current stuff will wash the salt off the roads as it’s just melting.
Yes, all the models show very little for now and accumulations later (although radar watching is the best bet as it's hard to forecast)
-
Worth noting that most models don't show any significant accumulations until later.
We have 4cm on the grass/natural and raised surfaces now.
But as the snow gets heavier it is sticking to more areas of the drive and pavement. Some big flakes now. Also though the temp is rising , up to -0.1c now from -1.2c earlier so unsure what the next few hours will bring.

Could be some big depth differences between grass/raised surfaces and roads/pavements by the end of this.
Anyway snow cover looks fantastic away from the surfaces that we humans have put in. Go to an open field or just look at the back garden and it is a winter wonderland.

Yeah it's started settling in places too. Just need it to get a bit heavier.
