  1. Well after this morning almost blizzard type conditions this afternoon has been a bit of a let down. The snow generally has stood firm to the 2 degree temperature we have had here, only really melting where the sun has got to work, mainly roofs. Hope to get a bit more tonight and tomorrow, just hope we get below freezing again this evening, its been quite a challenge at times. Could someone explain to me how during the december cold spell we managed ice days here, but now we are hovering around 2/3 degrees. Would love to know why.

  2. Morning everyone, Been snowing here, on and off, since around 5.30 - nothing substantial here, but some places to the west

    of me have been badly affected.

    Taking a look out of the window, I'd estimate that there's been around 2cms of fresh snow - so far :clap:

    We have a few inches here at least and still falling. Extremely pleased.

    Its going to get very server south of our region.

  3. it should still stick though shouldn't it ?

    If i'm right, the closer the dews and temp, the better the saturation. So they could be some fairly heavy falls. Also if history serves me right, you get better falls when its big fat wettish flakes. As long as the surface is at 0c or below (which it will be)

    It would stick and would be deeper compared to dry snow. Between York and Malton about 5 inches fell in 1 hour new years day, the impressive depth was partly due to the massive flakes that where falling.

  4. I wouldnt worry about warm sectors tonight. Bear in mind this front is coming up against bitterly cold air entrenched at the surface, which will be further enhanced by clear skies for some time before the cloud arrives. Temperatures at 850hPa level look pretty favourable too, never rising above -6C. The thickness at 850-1000hPa level is a more important pointer (essentially the distance between the ground and 850hPa level), which over this area rises to a maximum of 1290-1292 (under 1290 is preferred and indicates 70% chance of snow I believe) so also pretty good. The zero degree level is also around 100-200 metres or so, which pretty much guarantees no melting will occur on the trip to the ground.

    It suggests to me big wet snow flakes rather than finer dry snow. Rain away from the beach would be very unlikely.
