    I'm interested in this second bout of precipitation due Thursday morning. The difference here is the Low over us and to our SW is being pinned just-about in situ by that NE'ly. Don't worry too much about the above-minus 5 T+850 tamperatures. I've seen snow from 850-hpa temps above this before.

    Wow, looks seriously heavy snow on that photo!

    I'm watching the area of snow over the Thames Estuary with keen interest. Particularly the part of it over Essex. Could that move westwards and clip Bristol? Running the Netweather Extra 5-minute radar for one hour animation, shows the snow flurries are moving just-about directly from the east, but maybe very slightly north of east.

    Chances still look good to me? Snow risk remains above 75% during these 9-12 hours. Seems the mild sector just skirts a fair distance to the north of Bristol, keeping us in snow.

    The Netweather 7-day forecast for Bristol, now shows all precipitation tomorrow and Tuesday as snow. Yesterday it was shown as turning to sleet - a sure indication the warm sector is now much further east or less pronounced than once predicted.

    And I think if I got hardly any snow I'd be a bit :lol: :o But if I did get inches of snow I'd be saying: !

    Just noticed the temperature plummeted greatly (can't think of the exact opposite word for skyrocketed) by about 7C in (less than?) an hour on the last 44C day.

    Well, the green for sleet precipitation type colours have appeared on Netweather Extra 5-minute radar to NW of Edinburgh already.

    I would be annoyed if Bristol got no snow at all, but the Isles of Scilly had some!

    I don't like the way the charts on the BBC totally play-down how widespread the snow showers could be. Anyway, why are the forecasts talking about snow showers, when in fact there will be more-organised bands of snowfall, associated with weather fronts?

    And the 'Craven-esque' red mac!

    opplevelse - did it thunder in Melbourne after the maximum plummeted from +44C to +27C?

    I'm not certain if this is due to how individual computers are set-up to save pictures, but I'm wondering if images of weather charts could always by default save as, for example, JPEG, GIF or PNG, rather than Bitmap. It would make sense, considering Bitmap images are not allowed in the forum posts due to their size. Ok, I can get around the problem by opening Paint and saving the Bitmap as, say, a JPEG, but this wastes time.

    Belfast must have had a big top-up to their January total. Just seen on the Netweather Extra 5-minute Radar archive, this North-South oriented band of rain kept regeneraing as it moved north along itself. Heavy rain lasting at the very least 5 hours from just before 9pm yesterday evening.

    *IF* it snows for as long as predicted, I reckon Bristol could see upwards of 4 inches (10 cms), as we seem to be fairly close to the Low pressure centre to our SE on Monday (on the colder NW side) and close to another centre of Low Pressure to our SW midweek. It all depends on the temperature ahead of this second Low Pressure. Best chance of snow for these parts since at least Feb 1991 and maybe January 1987.
  16. Thundersquall
    Unusually the Southwest seems to be one of the highest-risk areas for snow, presumably as the air to west and north of the Low Pressure is colder than to south and east.

    Many thanks for poster - think I'll have a look either tomorrow or next week, am a bit tired to make sense of formulae tonight.
  18. Thundersquall
    Wow, those temperartures have risen in excess of 50C in no time at all. I assume this is significant as well as very unusual? Could this mean not only are we to expect a very cold February 2009, but continuing into summer with very cool and disturbed conditions?
  19. Thundersquall
    Has there been a year where a UK Winter has never seen a double-figure maximum anywhere?

    How many times does London City have an ice day? Must be exceedingly rare these days.
  21. Thundersquall
    The CET is minus 0.36C at the moment, and I think was minus 0.11C either Monday or yesterday. This is 4.56C below the CET average for Janauary. When was the last time the first week of January had a negative CET? January 1987 perhaps or even as far back as January 1982, as the 1987 cold didn't start I think until mid-January?
  22. Thundersquall
    Those very warm spikes during late January and throughout February 2008 looked interesting. Did they correspond back then to any major cold outbreaks at the surface?
  23. Thundersquall
    Love this amazing photo with the setting Sun highlighting the storm clouds.
  24. Thundersquall
    Wow, the Lampeter figures are about 62 inches!

    A warm welcome on this chilly but clear winter's morning. Nice sunrise appearing here over Bristol, the Sun picking-out aeroplane contrails in various shades of ever-brightening orange. Not much cirrus about so the sunrise is not all that spectacular. Promising signs of a Scandi High trying to build around Christmas, but the charts may not be as promising nearer the time.
