Rain now stopped so still some snow left. Warning should have been for ice not snow so another weather front off NO as per normal.
Yep, very very poor ... and the kick in the teeth will be that it shll be like an ice rink in the morning and no doubt I will be the first to slip over !
-
Nice to see other people getting snow ... merely frustrating when I know areas to the south of me will see a decent covering as the band looks like intensifying for them.
-
All you can do is laugh at the way the ppn arks around my area and the heavier stuff shuttles east and west .... Same thing as what happened two years ago ... think maxdamage had the image up earlier
-
Even if any of the ppn that does arrive is snow, will not amount to much, weakening around here with the heavier stuff all to the east and no going south west.
-
-0.4 here and snowing very lightly from a rogue shower that has crossed the pennines ... is somehow managing to leave a light dusting though over the pavements.
-
Gap forming on the front and I can guess where that gap will track. Striaght across here. Dew point stopped rising still having the odd snow flurry as well.
Yep PIT, looks that way ... been looking at the ppn charts for the last day or so and it has consistently shown the band weakening considerably down the spine of the country, leaving us with only a short period of lightish snow. This has been my biggest concern, was always confident everything else was conducive to snow for us.
-
Temps still hovering around the 0 mark here - beautiful crisp winters day so far, wall to wall 'dazzling' sunshine.
Approx 0.0000009 mm snow has so far fallen - hoping the warm sector in the front currently leaving Scotland doesnt spoil things later..
Text from a few lads at the SUFC vs QPR game say it was an 'interesting' journey down the country earlier this morning, navigating through sub zero temps & black ice!!
Off topic but I hope they're warm, it does seem to catch a biting breeze at Loftus Road ! (coming froma QPR fan who is from sheffiel lol)
-
also there is a risk that the heavy snow showers could make their way into our areas from the NW flow?
Hopefully they will, the isobars look pretty tight. As the runs have got closer to the time, the ppn it shows has spread further eastwards with alot more convection ... it's only the pennines that can stand in our way really.
-
A new streamer is setting it's self up near me, should see some heavy and more prolonged snow shortly
But still even the earlier runs today did not show a warm sector of 850's yet dews remain the same in + figures on the 18z, there's no modification from the N sea as the wind direction is more of a NNW, so maybe the gfs is just over cooking things?
I hope anyway

Looking at the NMM model, it shows more clearly that there is only a very thin wedge of -5 upper air before the ppn, but that doesnt reach completely across the region, with in eastern areas, such as yours, the 850's only drop to -6.
-
thats what happend with that march easter event as sheffield only had 3cm and here in doncaster had 7cm.
Hope that doesnt happen!
I hope so but c'est la vie if it does ! ... I remember quite a few of the more marginal times when I've got some significant snow here due to my elevation and you've been stuck with a slushy covering that quickly thawed. It's all swings and roundabouts ! But let's hope we both get a good solid covering for a change.
-
at least sheffield and doncaster will finaly get a covering!
Exactly ! only managed a "sugar coating" last night ... the only thing thats worrying me is that from looking at the NMM model, the ppn seems to split and pull away eastwards around the humber. Hopefully this will not be the case, and the bbc and MetO seem pretty bullish about it making its way down the spine of the country.
-
I agree, and i just hope lady luck is on our side.
Come to think of it i remember the Easter snow event, i think we had -3 to -4 uppers here and it showed the dewpoint's here at 1-2c @ one point, and we had like an inch or two of snow.
Lewis
Yeah, I do hope so. It seems like sometimes you can get situations where the uppers and dews don't seem that favourable if we saw them on the models but have still produced some quite memorable snowfall events ! ... Hopefully what could help the eastern end of the region is that the band looks like it may be heavier the further east you go, so may help to compenseate for the other areas of marginality.
-
yeah but think about it, temps rising to around 3-4c with the warmer uppers, precipitation at its heaviest is when the higher 850's are here and +2 dew points, you really think we'll see accumulations from that?
Lewis
Admittedly, places on or near to the coast may struggle to see any settling snow, but you could expect this due to the warm north sea nearby. However, for other places, dew points max out between 0 and 1 in the very east of the region, and less the further west you go, we are all sub 528 dam quite easily, and the uppers raise to about -4 for a short period of time and with cold surface air entrenched, and the ppn arriving at night time, I feel it should be enough to give most areas a decent amount of settling snow.
-
Not as good, the northerly is a toppler, introduced warmer 850's to -4, think it's gunna be too marginal.
Dews also on the plus side when the precip hits at 9pm, then half way through they sink below 0..
Lewis
How is the northerly a toppler? ... the 850's it brings in are not around -4 to -5 for long, maybe an hour at best if at all.
-
Although quite an IMBY post, I think that tomorrow night front will give a much better chance to those areas who haven't recieved, much, or anything in the way of snow yesterday and this morning. It is looking quite good for the central strip of the region, with more favourable dew points, temepratures and in some other areas elevation (which may also help to provide more ppn the higher up you are).
I'm thinking maybe 2-3 cms on low ground and towards the coast, with around 5cm for many areas above 100m, and perhaps upto 10cm in some lucky areas with some decent elevation (250m+).
-
Once more, another different varaiton of the output from the GFS, this time with the HP only centered over us until FI. Hopefully, one of the tiny things we can take away from this is that maybe the models still are undecided with the pattern that will take hold, and sometimes this uncertainty can sometimes be good as the models are not used to such synoptics.
-
I dont think it will mate, to be honest its just raining now, if further south are seeing snow and most up here seeing rain, it must mean were on the wrong side of marginal ?
The only thing which is helping further south is due to the evaporative cooling effect of the heavy precipitation, the other factors are indeed even more marginal.
Hopefully the temperatures will begin to peak shortly, so let's hope we see some heavier precipitation to give us some evaporative cooling effect to counteract the increasing temp and dp's :lol:
-
The updated next 48 hour forecast showed the dew point rising through the night and peaking about midnight. This is taken from the NMM model. As i said though its supposed to be 2.2c dew point now when in actual fact 0c. I'm just hoping we get something a little heavier later as at the moment its just going to be a sugar dust coating. Not complaining though considering i was expecting mostly rain tonight.
Sorry, my mistake, I didn't check the dewpoints ! I'm presuming mine must be around -1 at the moment with a temperature of -0.3. Hopefully because I have a tiny bit of altitude, I might just be able to stave away the effects of the rising dew points, even when they peak.
Do you think that is possible or as the charts are already wrong that it could look a little more hopeful of the dp's staying low enough?
-
According to the updated NMM model its meant to get more marginal, then again the dew point is meant to be 2.2c when in actual fact its exactly 0c and is still dropping ever so slowly. Best thing to do now is watch the radar and the all important temp
Just checked the NMM model and it looks to me that the most marginal time for snow has passed, the highest 850's and thicknesses were between about 6pm and 7pm, which has obviously passed, and both the 850's and thicknesses decline from then throughout the night.
-
Doesn't be playing by the book at the mo does it. Snow certainly getting heavier see it quite clearly under the lamp post at the bottom of our garden now.
No it does not, I think that perhaps that little low that appeared on the south coast earlier may have reduced the warm air advection brought in by the low and allowing the colder uppers to remain intact. I thought things were a little strange when at 5 o'clock the temperatures hit 0.
Still, lets not get out hopes up too much but things could look good for this evening.
I think our snow shield must be out for repair at the moment !
-
Temperature of -0.4 here in SE Sheffield at 200m with light snow that has covered all surfaces, including the roads. I didn't think that it was meant to be this cold at this time? ... and aren't the thickness values and 850's supposed to become more favourable from about 9 o'clock too?
The band of intense ppn finally has started moving north eastwards, hopefully I will see some slightly heavier ppn here by around midnight towards the early hours? Is this possible?
-
LOL
Just started snowing a bit here as I put the wheelie bins out. Now 0.4C and dew point of -0.6C.
Yes, it's like snow mist lol Temperature dropped to 0.0 now. I didn't think the temperatures where meant to be this low.
-
Wish things looked more positive maxdamage but the general concenus seems that the low is further south and the ppn will not reach here now
-
Temperature here of 1.2 and light rain.

few flakes starting to fall now ... may well just get my sugar coating back to its previous levels
... what a night haha
