How much do people see evaporative cooling coming in to play and from generally which areas? After the 12z, I was quite confident about my chances of snow, being at 200m but now after looking at all the factors on the 18z, I am a lot more doubtful. I can only see it being a rain to snow event for most places north of the wash (apart from the very northern extremeties of the precipitation) with very little chance for the snow to accumulate due to the already extremely wet surfaces. Would this be a fair assessement for places from the Wash northwards?

Would this be one of the scenario's where snow could fall, even with 850's of only -3, due to the sheer intensity of the precipitation? This event is looking very marginal, however I do feel that the BBC are being a little optimistic. It looks by the end of the precipitation that it may turn to snow but the ground may already be too wet for any signifcant accumulations. It also could be a possiblity that any extra little bit of altitude could make all the difference. If I were to stick my head out, I would expect snow from about the wash northwards with at least 200-250m altitude? Are those reasonable predicitions are even still a little too optimisitc for snow lovers?

Looks like a cm or two though at best. The PPN band is very narrow around us, unlike further south in the midlands again.

Snow cover being topped up very nicely here I would estimate that another 3cm has fallen here so far this morning and hopefully it might stall leaving us with light-moderate snow for a longer period.

Hope you get the heaiver stuff my friend ! Its only moderate here but settles so easily as the temperature is still -2 ! It started to get heavier about 45 minutes ago and there is now about 2cm on top of what we had before. I then took the decision to not go to sixth form as the roads in Sheffield will be appauling as there have been little, if any, gritters around and any snow just sticks to the ground. PS. Good to see you got the snow you deserved in the end TEITS ! ! !

It's been many years since I have witness the temeprature being a steady -2oC and snowing at the same time! Covering over the few inches we had from the other night's falls.

Do not think this is going to add much snow here in SE Sheffield looking at the radar. All of the heavier bursts seem to be fizzling out just south of here

I am posting here because this thread is much more busy and Sheffield is counted as the North Midlands from time to time Is it likely that the PPN will reach the south of Sheffield with at least a little bit of intensity intact? Even perhaps stalling slightly as the morning wears on? I think this shunt eastwards means more favourable conditions for snow to fall as surely it means that the colder uppers from the weat have pushed further east Good luck too all ! The ppn is not far away from many who are reading this thread !

Would you say this bodes better for the very south of South Yorkshire TEITS? Also, as it is further east, does that mean that the colder uppers are further east too, which will make it less marginal for certain places now?

How much weakening can I expect before it reaches Sheffield. The ppn currently looks quite heavy and will undergo frontogenesis as it moves north and approaches a steeper thermal gradient but will it have fragmented apart by the time it reaches here? The reason I ask is that the main band of snow on Monday was not very heavy at all but still managed to produce about 5cm of snow, so could this ppn produce even more than that?

Quite right. It wouldn't surprise me if they just didn't have any grit left as they are only doing the city centre. There is still a good inch or two on my pavements with a layer of compacted ice/snow in some parts of the road with snow still deeper on my back garden etc. I don't think we will get much from this band, perhaps 2-5cm at best but it would still be enough to cause some problems here. Do you think 2-5cm is a good estimation PIT?

http://www.metoffice.gov.uk/corporate/pres...pr20090204.html I have just read this on the MetO website about the snow event for tonight into tomorrow and I am honestly thinking ''WTF''. Why would snow in the southern belt of the country and a wintry mix to the north of it? and especially rain in the north west where it remains sub -5 850's? I honestly do not get this.

Hope the schools are closed PIT ! Would you know if Granville Road is still bad as it was apparently very treacherous earlier with cars just sliding down it. The maximium temperature today was 0.4 and it is now down to -0.8 oC, so only a very slight thaw. Personally, I think the attempts of the city council was poor, very little effort made at all and I think they just left it too late. They gritted Sunday night/Monday morning but not afterwards and I think were caught out by the heavy snow through the morning which inevitably settled and left some of the quite major city roads (City, Prince of Wales) in a treacherous state.

I wish I was up near lodge moor, I bet the conditions are terrific Perhaps I am a little more borderline here as although the temperature is -0.1, the flakes are extremely small, more like ice pellets.

I know I am 150m higher but that surely doesn't bode well for me either Which is quite disappointing as there is still quite alot of new PPN prepping up! The mild sector must be more widespread as the GFS shows that it should be getting back to about -4 to -5 now.

The southern portion of the PPN seems to be prepping up quite considerably still and seems to be moving more in a WNW track, which would keep the snowfall around for longer. Was this expected?

Does it look like the band could still intensify/expand slightly on the back edge of the band or perhaps even stall slightly?

It seems like the precpitation type on the NW Radar is based upon the models rather than what is actually ocurring as earlier it had a straight edged block of green which didn't move whilst the snow moved around it. Hopefully the heavier band over lincolnshire will make it's way around here within the next hour or so. What do you think PIT? I can't see MetO's and BBC's predictions of 15-20 cm here tonight though, not really a chance unless some drastic intensification occurs.

Does it appear now that the PPN seems to be pivoting slightly and the more intense bursts will move more towards the pennines?

What is the thing you noticed? ... That's good to here Thankyou for all of your input today on this thread.

I'm at Intake, just down from the Manor Top It's really coming down heavily now with bigger flakes. Temp at -1.1 oC

After being in the slightly wrong position for last nights snow showers, now I currently find myself in a near perfect position

Is this all of the main band or will the PPN out to the east and south east intensify and track ne'wards. If not, there doesn't seem enough precipitation to last until the early hours of the morning.

I couldn't understand some of the reports too. Although there was only about 1-2cm here last night, it has snowed alot of the morning with the depth now at a good 5cm after quite a heavy shower at about 13:00, it is now snowing lightly now and we are on the periphery of the heavier, more organised band of ppn.

Is the band over midlands/lincolnshire the main band or is that just a breakaway band forming ahead of the real energy still to come up from the south east? What would a good prediction of snow be for SE Sheffield at 200m?
