Chilly weather is in store for much of the country as a cold front sweeps over much of New Zealand from late Sunday and into Monday.
MetService says, "this front is forecast to deliver a cold and showery south to southwest flow across New Zealand, with snow lowering to 200 to 300 metres over the South Island, and possibly 500 to 600 metres across the lower North Island."
But New Zealanders should expect a fine Saturday with the exception being the northern tip and the east coast of the North Island.
With Auckland getting to 20 degrees and most places in the South Island getting to 15-16 degrees.
MetService says late Tuesday, another front is forecast to approach the far south of New Zealand, and the west to southwest flow ahead of this front should strengthen.
Some say it's a stony smell, others say sweet. But we all know what it is: That distinctive earthy scent in the air just before and after fresh rain.
It's a phenomenon called petrichor, and we're instinctually programmed to love it, MetService meteorologist Georgina Griffiths told TVNZ1's Breakfast today as she answered a question from a viewer.
"A lot of people can't describe it but they actually really like it," she said. "And it's historical, we have an affection for this smell because originally it was survival. We relied on rain to live."
The smell, which is especially distinctive when the rain is just about to break a dry spell, is the result of oil in rocks that becomes an aerosol when humidity in the atmosphere reaches just about the same point that causes rain, she said.
The term petrichor, a reference to the blood of Greek gods, was coined by Australian scientists in 1964 who did a series of studies about what caused the smell.
"Basically, they tested in the lab -- they steamed distilled rocks from the Australian outback or somewhere nice and dry to see what would happen," she said. "And they identified what the smell was. It was actually a yellow oil that came out of the rocks."
Since then, some enterprising amateur geologists have tried to bottle the oil in attempts to make money off our natural affinity for the smell, Ms Griffiths said.
"I'm not sure if they were successful," she said.
