A weekend of two halves

October 5, 2012

The weekend is shaping up to be a cold one for most places, according to MetService.

On Saturday, the southwesterly flow that sweeps across the country is expected to be unusually cold for this time of year. Showers over the west and south of the South Island are expected to fall as snow above 500 metres, lowering to 300 metres for a time in Southland and Central Otago.

“The combination of strong winds and wintry conditions spells significant wind chill, which can be hazardous for young livestock and is just plain cold to be out in,” commented Peter Kreft, MetService’s Chief Forecaster.

The North Island, while not expected to be quite as chilly as parts of the South Island, still has a windy day on Saturday, with lots of showers in western areas and snow over the central high country.

On Sunday, the southwesterlies die out and the showers clear away. For most places, it should be a fine day with little wind.

Monday’s weather is likely to be rainy in many places, as a low advances onto New Zealand. “Northwesterlies persist in the north while much of the South Island will be in an easterly flow,” commented Kreft. “Because the wind and the rain are coming from another direction, the wet conditions over the South Island will switch to eastern parts.”

“Right now, there’s a Severe Weather Warning, a Severe Weather Watch and a Special Weather Advisory covering the severe weather expected today and on Saturday,” said Kreft. “These are updated regularly, and it’s important to keep up with them if the weather is likely to affect your plans.”
