South Island Detailed Forecast

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 Friday 26 August 2016

Conditions Summary:
We have mostly cloudy skies, light south-westerly winds and temperatures between 0 and -2c.

Synoptic Outlook:
I am happy to report that most areas of the South Island should see significant snow over the next few days. On top of what we already have on the ground this additional snow should secure the season and give us some excellent skiing/boarding over the next week.

There are three features to watch out for, yup, three! The first is a juicy low which will move across the Cook Strait this evening before heading for the Chatham Islands tomorrow morning. Snow will develop through this morning and intensify this afternoon and overnight as cold southerly winds kick in. We are looking at a heavy fall of 25-40cm down to 1200m in Eastern Canterbury which is closer to the centre of the low and tends to do well off a southerly. Much less will fall in Otago (2-5cm). Tomorrow will be partly cloudy in Otago under a weak ridge of high pressure. Snow showers will taper off around midday in Canterbury with clearing skies during the afternoon as the low waves goodbye out East.

The second feature is a cold front that will slide in from the west on Sunday bringing strong north-westerly winds and snow to The Divide and The Southern Lakes. Another cold front follows in quickly on its heels on Monday bringing further snow and strong winds to the same regions. In total we are looking at 8-15cm in Wanaka and The Southern Lakes with 2-6cm in Canterbury.

Friday 26 August:
Strengthening southerly winds. Partly cloudy in Otago with light snow showers intensifying for a time this evening. Cloudy with heavy snow developing in Canterbury. 25-40cm by midday tomorrow.

Saturday 27 August:
In Canterbury snow showers will fizzle around midday, skies clear in the afternoon when southerly winds will ease. Partly cloudy in Otago, moderate westerlies.

Sunday 28 August:
Strong north-westerly winds. 4-10cm of snow in Otago to 1500m. A dusting in Eastern Canterbury.

Monday 29 August:
Strong north-westerly winds. Another 2-8cm of snow in Otago, a dusting in Canterbury.

Extended Outlook:
What better way to enjoy all of the fresh snow than a couple of sunny days with light winds. Well, nature has your back - a high will drift in from the Tasman providing exactly that on Tuesday and Wednesday. Winds will strengthen from the north on Thursday as a weak low spins in from the west. The northerlies will import milder air bringing the possibility of rain along The Divide. A heavier dose of rain is possible later in the week between a high out east and a low moving down from the Tasman but it’s still a long way out. I will keep you updated.
