Just a small change I think with the polar vortex over siberia on the 18z. Looks more eager to push south instead of being swept away to the east on this run. Would be great for forcing the high to move to our Northwest, hopefully it continues.
-
Getting heavier now, would be nice if this first front was snow for the duration.
-
Leeds getting hit pretty bad, must be around 6-7cm of snow at Hyde Park.
-
Heavy now with decent flake sizes
Got around 1-2cm in city center. -
She's on her way....
Just imagine if that vortex spills over Scandinavia, would be irrelevant that it's later Feb/March, that would easily give us the coldest weather of the winter.
-
100% snow here in the city center. Only settling on cars though. Tempted to go to the park which is 50 meters higher.
-
Well let's hope round 2 lasts longer. 9pm onwards is the time the bbc expects the big area of ppn over our area.
-
Instant heavyish snow here, what happened to gradual intensification?!? Already starting to settle.
-
Big gap in the front and guess wheres that going. Sheffield. So unless that closes up in the next hour we will miss out mostly. Looking good elsewhere though.
It's intensifying on the west side of that gap
-
Metoffice showing over 32mm per hour of rain at lancashire at the moment. Imagine 30cm of snow in one hour...
-
If current map on meteoradar is anything to go by then I think Sheffield will miss this. Pennines doing its trick of killing off the front and wind blowing NE doesn't appear to help.
I could of course be proven very wrong, that and there are hours to wait yet.
If you're looking for snow before 6pm you're going to be disappointed, the main front won't get here until the evening, with the heaviest at around 9pm.

One chart that I find very useful for when the most intense precipitation will come is the 700hpa vertikalbrew chart on the GFS. This shows the negative vorticity advection (yellow through to purple) to be at it's strongest over Yorkshire somewhere between 6pm and 12pm.

SSW's are by no means fully understood, and as was mentioned before, they are no guarantee whatsoever that cold will result in the UK. I do hope, however, that the people who promised the HLB a few weeks ago will now have a long hard look at the theories behind what they said, and why HLB has failed to materialise. Of course, there is time still. I can't believe that somebody in this thread has already written off February. Pathetic!
HLB has occured, just not in our tiny corner of the world. Much of America+Canada is suffering from intense cold due to high pressure in the arctic linking up to high pressure in the North Pacific/West America. If they promised HLB exclusively to the UK then I take it back, but I'm sure they didn't.

Well Leeds is forecast heavy snow untill 11am according to met office so there must be something in that ppn around the wash. Even if we don't get it, I'm so happy with the snow that's fell, it was looking so bad at one stage earlier in the night.
-
The difference a few metres can make...It hadn't really settled here, but when I went for a walk to the park which is 50metres higher than where I live it had already got a good 3-4cm of snow, though it's finally starting to settle down here
-
I've got a feeling this could be the best snow event in years
Yep, I'm already on minus 3cm so far
-
It's almost stopped now. I've gone from having 5cm before the snow to 2cm, this snow event has been so bad that it's actually negatively accumulated.
-
Anyone around Leeds with settling snow? It's getting wasted here in the city center...
-
Gritter has gone past, though low elevation is doing the job for free.
-
Getting a bit heavier now but still not settling. I guess it will take another 30 mins/hour for dewpoints to cool down.
-
You do realize the pennines are to the west of you and the front is coming in from the east?
I know, but NW leeds russ said it's heavier snow out to the northwest of leeds, which is on much higher ground. I do admit it was a moment of panic though, happens every snow event lol.
-
Edit : Moderate now and covering bit where the kids have played on it. Wind blowing snow from moreof ENE direction with my eye.
Uh oh, looks like the Pennines ruining everything effect may be kicking in then... Here in low-lying part of Leeds it's still very light.
-
Just started here in Leeds.
-
A heavy pulse has developed over the Wash.
-
Well the snow to the south has stalled for the last two hours and it's beginning to weaken. The system is also beginning to pivoting so it may have possibly have reached the furthest point north that it will go.
Lol we would have to take a good long look at the models if they're getting things wrong at 6-12 hours away. The main band of ppn off the east coast is moving North fine. I'm guessing that light stuff ahead of it isn't part of the front and it's just some convective stuff like what we saw on Thursday.
Got around 1-2cm in city center.

Yes this might be one of the few times in history where a shortwave actually helps us instead of ruining everything.
