Polar southerly coming in again this weekend
Snow flurries are being forecast for the Desert Road this weekend as another polar southerly moves up the country.
WeatherWatch.co.nz says Friday is warmer than average in a number of regions, but it's ahead of another polar change arriving Friday night in Southland and spreading up the South Island over Saturday.
Later on Saturday it moves into the North Island with a cold Sunday on the way for some areas, especially those in the east.
Snow levels in Southland on Saturday morning may be as low as 100 or 200 metres. Otago sees snow levels of about 200 or 300m and Canterbury should have snow to 500m lowering to 300m later in the day, possibly to 200m for a time.
6pm on Saturday.
"Please note lower level snow won't accumulate to much and in some areas it will be mixed in with rain.
"Wellington gets the cold southerly change on Saturday afternoon, after lunchtime. It will be a wet and windy Saturday night with snow to 400m around the Capital," says the weather organisation.
The cold marches on northwards overnight Saturday and into Sunday morning. Snow flurries to 500m may affect SH1 the Desert Road for a time and also potentially SH5 between Napier and Taupo.
"Daytime temperatures look miserable on Saturday in the southern and eastern South Island with single digit highs.
"The North Island has some pockets of warmer than average weather on Saturday but colder south east winds drop temperatures on Sunday.
"A good example is Napier which has a high of 17 degrees on Saturday but just 9 degrees on Sunday.
"Places warm back up again by Sunday in the South Island and Monday in the North Island."
