Warmer for all to start the week

November 23, 2015

The start of the working week has seen fine weather conditions across much of New Zealand, but a front brings a sustained period of rain to western parts of the South Island on Monday and Tuesday. MetService has issued a Severe Weather Warning and Watch for heavy rain for the Westland ranges south of Otira, Fiordland, and the headwaters of the Otago and Canterbury rivers and lakes.

“The ridge bringing settled conditions to the North Island today will slowly move away to the east on Tuesday, and the northwesterlies that  follow will push scattered rain across northern parts later in the day,” said Meteorologist Rob Kerr. “In fact, northwesterlies delivering warm,  moisture-laden air from the north Tasman Sea will be the theme of the week  for New Zealand, splitting the country in two: cloudy and wet in the west,  and warm and dry in the east,” he added.

“Wednesday will see a break in the severe weather for the South Island’s West Coasters, but heavy rain is expected to return there on Thursday, with  severe northwest gales possible for eastern parts of the South Island and  lower North Island into Friday, ahead of a cold front,” said Kerr.

Looking beyond the working week and into an event-filled weekend for many New Zealanders – including Auckland city’s Santa Parade and the Lake Taupo  Cycle Challenge – unfortunately the forecast is a pessimistic one.  Rain  and strong northwesterlies are expected to sweep over the North Island  during Saturday, while a colder change moves over the South Island.  Conditions ease dramatically later on Sunday as a ridge builds over the  country.
