Not sure if this has been posted today but for anyone thinking of driving in the SW then check conditions before you do - this is a photo on various news web sites of a gritter between Torquay/Teingmouth this morning

Snow still coming down thick and fast in Stroud :)

I use my hill test lol, if it comes in enough to obscure the view to swifts hill I know its decent lol.

Must be another few cms down in the last 90mins.

Just went for a little urban walk around Uplands with the dog, no lead needed as no cars, and the drifting was pretty impressive in places.

All in all a fantastic snow event.

 

Same here with hill test! Hills around Rooksmoor look like they are shrouded in fog. Snow much heavier than last night, not a whiteout but have 6 inches as an average with foot deep drifts on any slope. Great!

Anyone seen this amazing bus driver avoid the car? she essentially power-slides the bus around the car, incredible!

On the basis of the driver filming it having kittens, I wonder what the driver in the way of the bus was saying!???

After this spell of snowfall this afternoon, looks like there could be a few heavy snow showers later tonight and possibly a few light ones tomorrow morning.

I have about 50 red wings sat in the big tree at the front of my house. The're just part of an even bigger flock! Beautiful birds.

I nearly read this too quickly. I thought it said 50 red warnings on Saturday :D Sorry, I'm suffering from posting fatigue.

While I'm still waiting for the edge of the new snow band to hit, I'll knock out a few charts but with few comments this time:

It seems that what I said (an hour ago in my post on page 293) about the slightly more favourable and less marginal conditions is helping to keep this second precipitation wave as an "all snow" event (at least for now at 1430). Although it is generally rather less cold, the surface cold has yet to be fully displaced and may take several more hits or a very slow and gradual rise in temps. Most of the region seems to be around -0.5c to -2c and about 1 c lower than before the snow band moved in. The dew points are still pretty low. The 850s rose just above zero last night but have fallen back to sub zero levels (not normally cold enough for snow but the other factors are all just in our favour right now). At least the uppers keep it as snow up there and the mixed middle layers may be playing ball this time - we'll see. The main thing is the flow direction. The Scandi HP is still there in situ, albeit a lot weaker now. Emma has changed trajectory as she is trying hard to push through the block but has not yet succeeded. The precipitation bands are now coming from northern France on a more south-east to north-west trajectory rather than yesterday's south to north path. In fact that secondary LP centre that has just developed over northern Italy is assisting with this and Emma herself may well be pushed north-west where she will do much less damage. There are other LPs in her rear which need to be monitored. Each push weakens the block a fraction more. If this trend continued (Emma to NW and north ital LP pushes further east and deepens) we could bring the easterly back in (not as cold as before but cold enough) although other factors are involved too. Very much one to watch now.

With the flow becoming more east-south-easterly, the winds are more due east (winds blow slightly across the isobars away from HPs and towards LPs). This means that instead of crossing the whole of the Channel (with its modifying effect to the near surface layers) it is coming more from north France and Belgium with a shorter sea crossing to the UK and then across the far south of England on its way to the south-west. The cloud and precipitation associated with this second band is continuing to pivot slightly and more favourably, hence the snow area moving further west than had been predicted just a few hour ago. South and south-west Devon (including me in the middle) are right on the south-western edge of all this. Just a few flakes so far (-1 c at 1500). Like yesterday, this is an evolving situation and the snow area has been expanding. Just how much and how far is very difficult to say. You can see in the infra red that the area of thicker cloud (the brighter colours usually represent precipitation but not necessarily so) is still expanding and developing as it moves into the UK. There is still some undercutting going on with the incoming less cold air still being forced to over ride the denser surface cold. Just how much longer can our faithful block hold on for? The forecast is for the less cold conditions to slowly move in - meanwhile let the battle continue.

More snow falling.

I've experienced some of the deepest (drifts) of my life today.  Some were in excess of knee deep.

Only downside, it slowly disappears from tomorrow onwards.

Bitter pill to swallow lol :cray:

I've spent the last few hours setting up a PHP gallery on my website. I'm still configuring it at the moment, but i'm going to add all of the weather photo's that I have, including some from yesterday. I'll post the link the later.

ps: just started raining, so that'll freeze again!
