The Mountainwatch Detailed Forecast is provided by our resident meteorology sensei "The Grasshopper". The South Island analysis is issued around 7am every morning (maybe later on weekends) 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.
7:00am Saturday 25 June 2016
It is a clear and cold start to the day with moderate winds and temperatures between -1 and -5c.
We are still yet to hit the big time in the South Island (apart from The Remarkables 100cm from last month which is becoming a distant memory) while our friends across the pond will enjoy good conditions this weekend after a recent storm. Closer to home, a weakening low in the Tasman moves towards the Cook Strait today. As it homes in this afternoon it’ll become increasingly cloudy. A period of rain will cross the Canterbury High Country early tonight before pushing into The Southern Lakes and Wanaka later. It won’t give us bucket loads of rain, we are only talking about a few millimetres. The low will spin across the Cook Strait and weaken significantly on Sunday before heading out towards the Chatham Islands on Monday. It will flick a dusting of snow onto the Canterbury High Country as a brief period of southerly winds kick in just before it disappears to the east. This is less than what has been suggested in previous days. The low is weaker than previously thought and quicker to move offshore.
Tuesday will be sunny and mild as a weak high build in from the north.

Saturday 25 June:
Sunny start. Increasingly cloudy later this afternoon with moderate easterly winds. Light rain developing overnight.
Sunday 26 June:
Strong winds during the morning may cause wind hold. Rain early on in Otago will clear to leave a partly cloudy afternoon.
Monday 27 June:
Partly cloudy and colder with 2-5cm of snow in Mt. Hutt.
Tuesday 28 June:
Sunny. Light winds.
So by this point you must be thinking, please Grasshopper, tell me there is some snow on the horizon!? Well, there is something on the horizon... Wednesday and Thursday will be mostly fine under a high. Easterly winds will pick up in Canterbury as a low way to the north edges south kicking our high out of the way. As the low moves over the North Island and then tracks to the south-east it could give a period of heavy snow above 1600 to Canterbury resorts such as Mt. Hutt on Friday. However, this event is still quite a way out and I wouldn’t be surprised if the lows track changes so it’s one to keep an eye on.
