A low pressure system over the North Island and stretching down off the West Coast of the South Island brings an increasing southeasterly airflow over the country tomorrow.
Showers for the east of the South Island bring snow flurries to low levels, perhaps even a chance of near sea level snow flurries at times for Canterbury. Marlborough sees a few flurries to 300m. It must be noted that snow is fairly light and accumulations are small if not non existent for some. The biggest totals will be inland about hills and ranges naturally.
The West Coast of the South Island has a reasonably sunny day due to the sheltering nature of the Southern Alps, it’s like a reverse northwesterly airflow but this time the east coast gets the cloudy and showery weather. Not particularly warm in the west despite the sun with high’s only just getting into double digits.
The lower North Island sees some snow to 500m, perhaps 400m about the ranges near Wellington. The Central Plateau sees flurries to 700m lowering to 600m in the evening. Snow to the levels mentioned above may be heavy for the ranges of Wairarapa and Hawkes Bay.
Rain heavy at times for the East Coast of the North Island afternoon onwards. An area from Auckland and down through the Waikato may see isolated heavy showers in the afternoon with a chance of small hail then easing evening.
Southeasterly winds strengthen about the lower North Island and top of the South Island from afternoon also.
