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.
7:40am Monday 6 July 2015
The winds should ease a little but will remain bitterly cold. About 15-20cm fell last night, and it should continue throughout the day.
The westerly flow continues with winds expected to ease slightly from the gales we’ve been seeing but will blow at around 50 km/h from the west. Snow showers will be heaviest closest to the divide and strong winds about the upper mountain could cause some wind hold. The wind will tend southerly from Tuesday afternoon and remain cold, but I still can’t see enough moisture for anything more than a few flurries.

Monday 6 July:
Snow showers continue and winds will ease from the west.
Wednesday 8 July:
A few flurries as winds strengthen from the south.
Thursday 9 July:
Southerlies ease, mostly fine.
The area of high pressure that is sitting to the south-west of the South Island will drive a brisk southerly from late on Tuesday into Wednesday. This won’t necessarily bring snow, but it will keep things cool, enabling the resorts to make snow wherever possible. Looking further ahead, it’s looking like there will be some more snow developing from next Wednesday as a cold front moves across the Tasman and brings a wet north-westerly flow, we’ll keep an eye on it.
