The cold spell that I talked about in my last blog is now looking more certain as very cold air moves across Dartmoor on Monday night. The bitter N to NW wind is likely to bring a mix of hail and snow showers on Monday night and during Tuesday. Difficult to say how much snow there is likely to be, but going on past experience about an inch above 300 metres asl would be a reasonable stab. After Tuesday snow showers are likely to die out when winds swing NE’ly and it becomes mainly dry and frosty with some ice. I will be updating my weekly forecast tomorrow at http://www.lyneside.demon.co.uk/weeklydiscussions.htm .
