  1. Hi all, hope you had a good day. :)

    So after this morning's snow which gave about an inch, it remained largely cloudy with an odd sunny break, until around 12:30pm. Some heavy snow at times this afternoon though was falling on wet surfaces. Perhaps 3-4cm on the grass, but looking lovely and wintry. Hopefully dew points should start to fall soon, with the chance of more snow a bit later on, I would of thought. Could be icy in the morning.

  2. Morning all. Somehow I'm up this early (on a Sunday!) so an update on the models for tomorrow.

    NAE:

    First band of snow arriving around 6am:

    Weakening as it travels east. NAE predicting only about 1-3mm of precipitation from this first band.

    Second band of precipitation arriving during the early afternoon:

    Second band delivers about 3-6mm of precipitation.

    A look at the dew points from midday onwards. Need the DP to be 0C or below:

    Looks OK for most of the region. Perhaps the risk of marginality towards the SW of the areas covered in this thread however this can and will change.

    GFS appears to be a bit more marginal particularly late afternoon.

    First band is fine as all snow:

    http://91.121.16.5/modeles_gfs/runs/2013011300/33-574.GIF?13-0

    However more marginal in the afternoon as the second band arrives, again more towards the SW of the region but the marginality on the GFS affects more of the region too on the 0z.

    Partly down to this milder wedge of air mid-afternoon, travelling south-east.

    As for the UKMO and ECM models regarding Monday and the 850hPa temperature, UKMO would look fine to me and ECM it's difficult to say because of the 24 hour period between charts, but has -6 850hPa over the whole region between 1am Monday morning and 1am Tuesday morning, admittidly not too sure where the mild sector is on this run, but looks OK to me.

    Met office forecast for east of England for tonight and Monday:

    Tonight:

    Staying very cold. Gradually clouding over with snow spreading from the northwest to all parts. This will lead to some accumulations, especially later, also some very icy conditions. Minimum temperature -3 °C.

    Monday:

    Cloudy and very cold, the early snow clearing for a time, but then further snow arriving during the afternoon. Some accumulations and remaining icy in places. Maximum temperature 1 °C.

    FAX's will be interesting this morning to see where they place the mild sector (last night's didn't have it near this region).

    Also for further interest, 3-5 day outlook for the east of England:

    Outlook for Tuesday to Thursday:

    Tuesday, very cold, bright or sunny intervals and snow showers, some possibly heavy near coasts. Wednesday and Thursday, very cold with a biting northeasterly wind and heavy snow showers.

    Updated: 0319 on Sun 13 Jan 2013

    All to play for.

    A more general model update shows the cold spell lasting untl the end of the weekend at the earliest, so more snow potential and cold- v.cold conditions over the next week I would of thought. :)

  3. Evening all, hope you had a good day.

    Tried to keep up with the latest developments, though sadly came across 'this winter is terrible' posts in the MOD. Unfortunately my phone isn't good enough to sign in and keep up with this thread!

    Thanks to John Pike for the update. Monday isn't set in stone, it will come down to radar watching and now-casting. Don't forget, the models don't control the weather..

  4. Losing the plot here! So what has happened to the snow tomorrow? Or could it be one of those surprise days when we get dumped on

    So basically we might get a few snow flurries over the weekend but the main event is on monday late afternoon ,is that right,plz can anybody enlighten me

    Here's an amended post similar to one I made this morning. :)

    Snow possible for areas south of the M4 corridor tomorrow, with a light covering in places. Snow showers on Sunday in Norfolk, Suffolk, Essex and maybe Kent, some showers pushing inland at times too. Monday into Tuesday could provide a significant fall of snow for the vast majority in this region. Snow potential continues thereafter, cold - v.cold conditions continuing with sharp frosts overnight.
