The winter blast of snow that hit parts of Otago and Southland on Tuesday won't stick around, but MetService says the below 0degC temperatures will.
Those low temperatures will mean the surrounding ski fields will have near perfect conditions ahead of the ski season.
"This is the first real storm of winter, it's going to put us on track, were aiming to open on Saturday," Coronet Peak's Nigel Kerr says.
"[This is a] big storm, we've got about 36 hours of this to come, and that's going to bring a lot of snow and a lot of snow making opportunities.
"Hopefully that's going to get us over the line and we're going to have a really fun [opening] weekend."
Sleety showers are expected to whip across Southland, inland Otago and Banks Peninsula overnight Tuesday and into Wednesday.
A crippling southerly flew up most of the South Island on Tuesday bringing a nasty winter bite with sleet showers, rain and heavy winds smashing parts of the east coast.
Wind warnings remain in place for coastal parts of the east coast with gusts of more than 120km/h forecast until mid-morning on Wednesday.
It wasn't all good news - snow left some motorists stranded on the Crown Range near Queenstown while authorities issued warnings for road snowfall.
Arthur's Pass, Lindis Pass, Haast Pass, Milford Road and State Highway 1 outside of Dunedin all had warnings of possible snow affecting parts.
The snow, rain and wind will pass throughout the week but negative temperatures will suffocate some area including Alexandra, Queenstown, Wanaka, Mt Cook, Christchurch and Timaru who will all fall below 0degC during the week.
