Another day of frustration in central Vic. Shower popping up as they head over the ranges, or dying as they approach. Bit over this pattern which has been so dominant since May.
Tomorrow looks better, but said that before. Still looks like snow or sleet a good chance here Friday arvo into Saturday. We should see at least 30mm here by Saturday...
That 145mm at Perisher and temps in the positive must surely have destroyed their snow cover? Imagine if it hadve fallen as snow.
Looks like this may well be the highest August rainfall in the snowies in August. There was a big rain event July last year (about 120mm of rain) and a big event in June 1997 (175mm). I suspect that big rainfall events like this are very rare in the historical record as they require unusually warm rain events which are fed by the warming trend in the oceans. You can get them in early winter from east coast lows, but these rarely happen from mid winter.
The snow pack seems to have lost about 30cm last few days. My experience in the alps has been that rain really hammers the snow cover in dips but is less an issue on slopes. It leads to wash outs and holes, and then increases future melt as the snow pack is warmed to 0C and has lower albedo and so absorbs more sunshine.
Thankfully, looks like a good few days of snow up there. Should get at least 30cm to patch the cover.
