The Heat Is On
MetService is forecasting settled conditions this weekend with soaring temperatures.
After
the severe weather experienced in the South Island last
week, more stable conditions are forecast. MetService
meteorologist Andy Best says, “The more stable conditions
will no doubt be welcomed by Cantabrians who experienced
severe thunderstorms, accompanied with hail and a small
tornado earlier in the week. Those in western parts of the
South Island also experienced significant weather, recording
between 50 and 60mm of rain along the West Coast on Tuesday
and a small tornado which was reported at Ngakawau (north of
Westport).”
Looking ahead to Friday, a broad
ridge of high pressure which covers much of the country
today, becomes confined to the North Island, making for fine
weather and light winds. Farther south, a front approaching
the bottom of the South Island brings increasing
northwesterlies in the east, pushing temperatures up to
around 27 degrees in Blenheim and Ashburton. Late on Friday,
the forecast is for a few showers in the south on a weak
southwest change.
High pressure covers much of
Aotearoa on Saturday, spreading the warmth over the North
Island, although, brisk southwesterlies over Auckland bring
morning and evening cloud to an otherwise fine day. Some
centres are expected to rise to around 6 or 7 degrees above
average for this time of the year, for example expect a
maximum of 27C in Masterton and Tokoroa, and 28C in
Rotorua.
The reason for these high temperatures is that we expect hot air over southeastern Australia to be transported across the Tasman Sea over the next few days towards New Zealand.
Settled conditions are forecast over the North Island on Sunday, with once again temperatures in the mid to high 20’s in many centres. It will be hot in some eastern parts of the South Island with a maximum of 30C expected on Sunday in Blenheim, and 28C in Christchurch. Later in the day, a cool southerly change spreads up the south of the South Island, bringing a few showers reaching as far north as Kaikoura in the evening.
