Will be snow chaos in London if the ECM comes off! All models showing some significant snowfall for most of our region. Hard to contain excitement..

ECM is towards the top of the 850hpa spread for London

Yes, a good set of models runs. Nowhere near as immense as yesterdays 6z GFS, but still good enough for plenty of snow chances (and not all convective). Some runs are better than others for widespread snow showers (GEM and UKMO), but on Tuesday most develop a small feature traversing south west which delivers a more organise period of snow. One to keep an eye on as we head towards the weekend.

So to summarise the 6z GFS Sunday: Light snow showers in the east Monday: Widespread snow showers Tuesday: Widespread snow showers Wednesday: Widespread snow showers Thursday: Show showers Friday: Heavy snow Saturday: Heavy snow Sunday: Heavy snow... Monday: Snow showers Tuesday: Snow flurries Wednesday: Dry An insane run for snow, with very significant accumulations in flaoured areas. Although just for fun I'd suggest 20-30cm as a minimum (widely) Subject to change of course, but shows how crazy some of these runs are!

Is less good for widespread snow showers, albeit good for the south coast etc..

There is a longer fetch. It will require the likes of the NAE, NMM etc.. to provide more accurate forecsts (especially for our region). The current graphics are based on the mesoscale models. In any case shower and trough activity is hard to predict, in most cases it will be nowcasting. Only thing to be weary of is winds veering SE.

Won't be doing that next week.. ?

Ignore the metoffice and bbc apps. They'll significantly underestimate the shower activity (especially at this range). Every model would give significant accumulations in the east of our region, with decent falls elsewhere.

Speechless - look at 204 http://www.meteociel.fr/modeles/geme_cartes.php?ech=6&code=0&carte=0&mode=0&archive=0

4.8c please

Moderate snow here, and sticking. Report's of snow in the West Midlands are promising

Same here, although only on top of the cars. Everywhere else is to wet. Still, it is very light. Lets see what the heavier precipitation brings, i suspect heavy sleet!

4.6c please

After a morning of heavy sleet, it has finally decided to turn to snow. Unfortunately just a slushy covering in places. A shame as Bramley (similar elevation) / Dronfield are under 10 miles away from me!

Turned to heavy rain after 40 mins. Ah well. Good luck to everyone else!

Not expecting much here, other than some transient snow. Would like to be western Sheffield though!

Was sleety in Harrow. Didn't last long though

Seems to be turning sleety in NW London. Still lots of snow / slush on the pavements. Can see a bigger risk of ice tomorrow morning!

Possibly an extra couple of cm's tomorrow

Yes pepping up here - may get a good dusting before it clears!

Very light now - snow melting on the paths. Plenty more opportunities to come at least

Yes getting a little heavier here. Can't see more than a cm or two though, which is still good.

Same here, constant light snow. Funny as i wanted to stay up north yet they have a good few cm's down in Harrow!

Yes, Sheffield, Doncaster and Rotherham still in the orange. Although it is really now down to radar watching. A reasonable covering for South Yorkshire, maybe a bit more than a dusting further north. For those that miss out, remember we are only on December 9th!

Yes - was in response to posts on the EURO model. ECM has some big depths across the Midlands associated with Mondays low
