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 Saturday 22 July 2017

Conditions Summary:
We have heavy snow to 1000m and gale force winds in The Canterbury High Country. Skies are mostly cloudy with a few flurries in Otago.

Synoptic Outlook:
Today is the stuff dreams are made of, at least in Eastern Canterbury. A low centred over the Cook Strait will start to track north-west today. Strong southerly winds will give heavy snow to The Canterbury High Country. We are looking at another 25-45 cm down to 800m! Taking into account the snow we saw last week Canterbury resorts are well and truly rocking it! Otago be getting a bit jealous, strong southerlies in the morning will ease as a high builds in from the west. We will have partly cloudy skies with a few flurries giving a dusting in places.

I’d imagine the snow crew will be working through the night in E. Canterbury to open tomorrow as it’ll be sunny with light winds. It will be one of the best day’s of the season. It will also be mostly sunny in Otago, westerly winds will pick up later in the day as a cold front approaches from the south-west. The front will swing across the South Island on Monday. Most of the precipitation will get caught up on the western side of The Divide. All the same there will be strong to gale force north-westerlies during the morning and a few showers, especially in Wanaka and The Southern Lakes where 2-10cm of snow will fall above 1600m. Tuesday will be partly cloudy with a few flurries about The Divide between a low way to the south and a high over Eastern Australia.

Saturday 22 July:
Heavy snow (25-45cm) down to 800m in Eastern Canterbury. Strong to gale force southerlies. Strong southerlies in the morning elsewhere will subside in the afternoon, partly cloudy with flurries.

Sunday 23 July:
Sunny with light winds in Canterbury. Mostly sunny with strengthening north-westerly winds in Otago.

Monday 24 July:
Moderate to strong north-westerly winds. Mostly cloudy along The Divide, partly cloudy to the east. 2-10 cm of snow above 1600m in western-most ski fields such as Treble Cone.

Tuesday 25 July:
Moderate to stong north-westerly winds, partly cloudy skies and a few flurries about the peaks, especially along The Divide.

Extended Outlook:
A rapidly moving low will slam into the South Island from the west on Wednesday. Winds will strengthen from the north and we will see a rain/snow mix in ski fields along The Divide. 10-25 cm of snow is likely above 1700m with a rain/sleet mix on the lower slopes. Thursday and Friday will favour snow in The Canterbury High Country again as the low moves to the east of the South Island meaning winds will swing around to the south. This could give another 10-30 cm of snow to Mount Hutt/Mt Dobson – as if they didn’t have enough as it is! High pressure will build in for Saturday giving us a mostly settled day. I’d imagine it’ll be one of the busiest weekends of the season. It will stay mostly clear on Sunday but strong north-westerly winds will develop as another cold front moves in from the west.
