Winter may officially be over, but it appears there is still some snow left over, which MetService is predicting will fall in parts of Otago and Southland on Wednesday.
A front is expected to move from the Tasman Sea on to the south of the South Island late tomorrow or early on Wednesday.
A MetService spokesman said a low associated with the front was expected to cross over the central South Island on late Wednesday or Thursday, and a larger low to lie west of the country late on Thursday.
He said there was moderate confidence that enough rain to prompt warnings could fall in Fiordland tomorrow and Wednesday, and in Westland on Wednesday.
"As the first low crosses the South Island, it is expected to lower the snow level in the east, with significant snow about the higher ground and some falls as low as 400m to 500m."
However, he did not believe the front would cause significant disruption to the region because insufficient amounts of snow would fall at 500m or below to justify a warning in either northern Southland, Otago or Canterbury.
MetService meteorologist Karl Loots said the fine weather of the past few days would persist today and tomorrow for most places.
"The story of today is just a few odd showers scattered about the place, but most areas will be fine."
Whangārei, Auckland and Hamilton were all in for a day of light winds, a high of 19C and the odd coastal shower. Coromandel, Bay of Plenty around the East Cape down to Hawke's Bay would also see temperatures in the late teens, with some showers mostly about the ranges.
The high pressure driving the fine weather spell would hang in there until tomorrow evening, before a strong, cold front arrived at the bottom of the South Island.
"That will be the start of the significant weather for the week," Loots said.
By the end of Wednesday most of the South Island would be doused in rain, with the West Coast in line for the most.
Temperatures were forecast to plummet - halving in places from the start of the week - with snow possible down to 400m.
This weather pattern would persist about the South Island through to Friday, with a low pressure system arriving from the west bringing potentially more rain.
The North Island would continue its fine spell through Wednesday before the front made its way north on Thursday. Rain was forecast for most places later in the week.
Loots said at this stage the heaviest rain mid-week would affect the "usual suspects", along the South Island's West Coast.
But when the low pressure system arrived Thursday it could bring heavy rain to parts of the South Island's east coast, central parts of the country, and the North Island into Friday.
