The South's week of summer weather is set to come to an abrupt end tonight with a southerly change forecast to bring snow to some roads.
Temperatures are expected to drop across the South and snow is expected on some mountain passes.
The forecast southerly has prompted the MetService to issue road snowfall warnings for Lindis pass where flurries are possible above 800m between 6am and noon tomorrow.
A warning was also in place for the Crown Range Rd where flurries were also possible above 800m between 4am and 10am tomorrow.
In both cases little if any snow was expected to fall on the road.
During the spell of warm weather Alexandra crossed 20degC seven days in a row and is forecast to cross it for an eighth time today.
The rest of the South has also basked in warm weather, including Wanaka which reached 26degC yesterday.
