The Mountainwatch Detailed Forecast is provided by our resident meteorology sensei "The Grasshopper". The analysis is issued every morning and is intended to provide an additional human element to the automated forecast data provided above. Sometimes we won't agree exactly with the model data - but if we ever call something significantly different we'll do our best to explain why.
It is partly cloudy. We have light north-westerly winds and temperatures between -3 and -5c.
South-easterly winds will develop today between a high out over Western Australia and a low which is forecast to pass near to Sydney. We’ve been following this slippery low for some days now. A few days ago it looked like we were going to get slammed with bumper snowfall. Then, the models shifted it away from the Aussie Alps increasing the probability of a total miss. Now, on the morning of the event it looks like we will scrape 4-10cm down to 1400m in NSW (With Perisher/Thredbo just on the edge of the precipitation band) before the low clears off to the east tonight. VIC will be cloudy in easternmost resorts with clearer skies further to the west – but it will miss the snow.
A weak trough of low pressure will give a few additional light snow showers or flurries tomorrow afternoon giving a dusting in places. Friday and Saturday will be mostly fine as a fat high builds in from the west. Night-time temperatures will be low so we will have perfect conditions for snowmaking.

Wednesday 24 August:
Cloudy in NSW with light to moderate south-easterly winds and 4-10cm of snow. Partly cloudy in VIC.
Thursday 25 August:
Mostly cloudy with light snow showers/flurries in the afternoon giving a dusting in places.
Friday 26 August:
Saturday 27 August:
Sunday and Monday will be sunny under the influence of a high. Watch out for strong north-westerly winds which will pump in increasingly mild air as the high slides east and a low marches in from The Bight. Unfortunately, it looks like we are going to end the month on a wet note. Rain will develop on Tuesday and continue into Wednesday as the centre of the low spins by to the south-west. Rainfall amounts could potentially be damaging. It is still a long way out but I’d say 15-30mm is likely. I will update you on this tomorrow.
