![]() "Graham Easterling" wrote in message ... Not knowing what to expect after seeing or hearing a weather forecast is something I'm used to nowadays. Anyway, 7C sounds about right for a "bitterly cold" day these days - i.e. temperatures about normal. The long track of northerly winds over warmer than usual water brings surface temperatures up to normal by the time the air gets here. -- Graham P Davis, Bracknell, Berks., UK.

[Chic Murray, 1919-85] Which I why I cannot understand how weather warnings for the SW have consistently given a 60% chance of disruption on Scilly due to snow, when the SST around the islands, which barely poke above sea level is still close to 11C, and there own forecasts have shown minima in the islands never lower than 6C. I would give the chance of disruption on Scilly (due to snow) as pretty close to 0. Rough sea commonly causes disruption to services there, but that never qualifies for a warning. Graham Penzance It is a fundamental problem with the warning system in that the resolution is too coarse. There could well be a significant chance of disruption over the moors which then is applied to the whole of the SW. Alan St Albans |

Alan St Albans- Hide quoted text - Agreed, but why specifically include Scilly in the warnings?, it's not part of Cornwall after all. It was quite a talking point here - with people expecting not just snow on the Islands, bit a lot of it (as 60% chance of disruption implies). Minimum of 6.3C in Penzance last night, despite fairly clear skies at times. Currently 7.4C, force 3-4 NW wind & sunny spells. I notice there's plently of showers over the sea. Graham Penzance |

I thought I had posted a reply, but I think I may have emailed it somewhere instead. I think the problem is that the MO have chosen a sub-region of SW England called "Cornwall & Isles of Scilly", so any warning for any part of that sub-region will have that title. I don't believe the intention was to specifically include Scilly in the snow warning. This just my guess; how anyone is supposed to know for sure, I don't know. I believe an overhaul of the warning output is in progress? -- Steve Loft Sanday, Orkney. 5m ASL. http://sanday.org.uk/weather Free weather station softwa http://sandaysoft.com/ |

It was quite a talking point here - with people expecting not just snow on the Islands, bit a lot of it (as 60% chance of disruption implies). Our main 'warning' area is Strathclyde which is subdivided when there are area variations into 'counties'. We are in Argyll and Bute but sufficiently close to E Dunbartonshire to make it worth looking at that for a forecast. Last night we were due to have 'severe' winds from 21:00 onwards. Again, it didn't happen. Why bother to forecast at the county level at all when it would be quite adequate to talk about 'some places' in W.Scotland? -- Alan White Mozilla Firefox and Forte Agent.
