Weekend weather: Winter is back
Strong winds, heavy rain and possibly even small tornadoes could be on the way for the north of the country this weekend, while snow is expected in the south.
Two weeks into spring, winter is fighting back.
Following this week's damaging winds and heavy rain, MetService is warning of snow showers to sea level tomorrow in Southland, Clutha and Dunedin and tornadoes in Northland.
A cold southwesterly flow was spreading over the country in the wake of a low pressure system crossing northern New Zealand tonight, MetService said.
An associated front moving on to Northland had a moderate risk of embedded thunderstorms.
"These storms may produce localised heavy rain, strong wind gusts of 90kmh to 110kmh, and the chance of a small coastal tornado," MetService said.
The moderate risk applied to Northland this evening and tonight, then eastern parts of Northland and Auckland, and the Coromandel Peninsula before dawn, spreading to the Bay of Plenty tomorrow morning.
A trough expected to move across the central and northern North Island tomorrow afternoon should bring scattered heavy showers and possible small hail from Auckland to Taranaki.
Meanwhile, the south was also due for a wintry swipe.
"A very cold southwest flow will spread over southern South Island areas on Saturday bringing a brief return to wintry conditions," MetService said.
Snow showers were expected down to 100 metres or 200m tomorrow, followed by sleety showers down to sea level in the evening. About five centimetres to 10cm of snow could accumulate above about 200m
Southwest winds were also likely to rise to gale force about the coast and hilltops tomorrow.
"Farmers and other outdoor workers are advised to prepare for strong winds and snowy conditions and shelter any vulnerable livestock," MetService said.
"Also snow may affect some roads in Southland, and eastern parts of Otago. Snow showers should clear from all areas during Sunday morning."
