  1. givingsome accumulations even to low levels by evening, especially across parts of Cheshire. Maximum temperature 0 °C

    That sounds like a forecast aimed entirely at low levels.

    I'm fairly confident that it's warm air from the low pressure system being forced ahead of the main front by the rather stiff SEly breeze. I think the correct term is instability.

    Yeah probably, summer storm setup in reverse. Forcing because of the topography of Wales and the Pennines is probably another factor, something which could cause the main band to intensify further though that's wishful thinking most likely.

  2. Still snowing here too, this area doesn't seem to be going anywhere.

    Something must be feeding warmer air in to the cold air and preventing it from dissipating, though what that is I can only speculate on. Warm air drifting in from the gulf stream, heat rising from towns and cities, a feed from the approaching system or possibly a combination of all 3.

  3. must admit I'd be somewhat sceptical reading reports of seeing lightning from 100 miles distance, so I've just popped outside, and sure enough saw 3 flashes to NNW in about 5 minutes, and I'm just 10 miles north of Wolverhampton!!...Flashes must be at least 80 miles away...astonishing!

    Indeed, lightning seems to be shooting out of the tops of these clouds as its moving closer to me now and the flashes aren't as distinct. Lower level clouds must be scattering the light more.
