  1. Four miles from the North Sea in NE Norfolk  I recorded three consecutive ice days from 28/2 to 2/3. 

    Lowest minimum was -6c on the 27th and lowest maximum -2.5c on the 28th.

    Snow was lying in the morning on 7 days. Depth approx 3” level with 2 foot drifts. Now gone.

    Windchill and freezing of exposed soil in fields which was blown as a brown stain onto the snow after it had eased was notable.

    Most interesting feature to me, who has only lived here a few years, was the influence of upper air temperatures on convective precipitation. Around here -8c with wind off the sea produces every form of iced precipitation except snow. At -12/13 each shower was preceded by a brief fall of ice pellets before it became all snow. Not before -15/16 was it all powdered snow. Frontal snow I know is possible with much lower uppers, but that has been in short supply these last few years around here.

    I remember Bill Giles talking often about snow showers pecking away at the east coast. I don’t think he could have lived this way!

     

     

  2. I am offering a simple and not very scientific analogy as to the conundrum faced by the models in working out where we go from here. Run a hot bath add cold water and mix. Burnt fingers, hidden hot spots just when you think it safe. How can models address that on a global scale. Give them a chance? Fiw I have a feeling that the high will migrate to Scandinavia SSW or not. ?

    Whilst nothing exceptionally cold is being shown in the models, its great to see the mean barely getting above -5c on the 850hpa temp ensembles (North Yorkshire) all the way out to 384hrs.

    Hopefully all members will see something wintry as we head into an interesting looking month for coldies.

    What I find interesting about that chart is the spread at +192. The op is one of the mildest. One or two go close to minus 10. Having looked at weather charts since the 60’s, I feel this winter has a few cold surprises in the tank.?
