  1. Probably a good 4-6" over the moors and it was blowing about quite a bit most of the day.
    At the top of the dale you could see it moving across the plateau and showering out into the valley when the sun backlit the area.
    Just a couple of inches here and though it was a couple of degrees above freezing ground temperatures stayed so low it only thawed very slowly.

  2. I was surprised on Friday the Derwent at Malton is fairly normal for the time of year.
    This is at Old Malton which often has problems partly because a small tributary backs up if the main river is high for too long.
    It has been up to the base of the flood bank a week or so back.

    Pump (not running) sends water over the embankment as required.

    It draws from this sump-like area which drains naturally to the river when the level is below yellow paint - above that they close the sluice gate and start the pump if it stays higher for long.

    The pub and houses across the road are considerably lower than near the camera, and very vulnerable.

  3. More than 25mm since it stated and at least another 3 or 4 hours to go.
    Never very heavy but so persistent - hardly even eased off but sometimes heavier than others.

    I get the impression there's been much less even a little further north?
    Another striking feature is the gradual cooling at about 0.2C per hour, it was 8C when it started but 3.8C now, would have been very grim if not almost calm. 
    There must be some wet snow in it above about 1000 feet I think.

  4. I'd say some of the higher fellsides have better than 50-50 chance of a brief snow cover through October, Leyburn itself is reasonably high up too.
    More realistically it would be surprising if one or two mornings didn't have a touch of frost.
    Here on the moors the average 'days with snow falling' this month is probably about 2, with light snow cover expected perhaps slightly less than one day on average.
    Having said that Leyburn on Met Office site shows around 10-12C most days with cloud and light rain at times so you are out of luck, the final week this year looks more promising at the moment. 
    Hawes further up the dale is  degree or two cooler with minimums of 3 or 4C some days - that's low enough for sleet over some of the higher passes like Buttertubs.

  5. You do sometimes get these raggy bits of cloud which may or may not be rotating, to be honest the shots aren't very conclusive. 
    When a definite funnel forms it's quite a tight structure, the edges look darker and more sharply defined. 
    A strong one will often develop into an almost implausible rope-like structure before dissipating.
    From a decent elevated vantage point small funnels are relatively common and can form below quite innocuous looking clouds which aren't even producing rain let alone electrical activity.

  6. Last year we got below 1C on 31st August, with fairy dry ground and clear sky it will soon tumble if there's not much wind.
    Cool northerly flow was established yesterday with outstanding visibility this morning.
    I took this yesterday looking south from Blakey Ridge with the last pokey showers heading towards York and Leeds.
    The southern skyline main features on such a day were three large coal power stations but now the horizon is fringed with ranks of giant turbines.
