A change in the weather occurred today, with a gradual decrease in temperature occurring from mid-day onwards, coupled with a steady onslaught of relentless drizzle (later heavy rain). This rain is falling above about 850m as snow although I have no way of knowing how wet this snow is. Given that the freezing level is probably about 1000m, it seems likely that snow is starting to build up on the highest slopes of Bidean nam Bian and the other highest peaks in Lochaber.
Freeze/thaw cycles and further blizzards are forecast over the next three days, followed by a sharp decrease in temperature, which is exactly what we need at this stage.
This development comes just in time to save what was left of the snow on Ben Nevis, which has been subject to drastic thaw over the past few days.
p.s. The Twitter weather update system is working out well. It only takes me a couple of seconds to update from anywhere in the Clachaig and I am glad to see that twelve of you have already signed up to follow the feed through Twitter itself. I find that I am also paying more attention to what the weather is doing, which is all to the good.
