Bye-bye High hello Low

June 7, 2016

The area of high pressure that has been bringing frosty mornings and sunny days to the majority of New Zealand is moving away to the east of the country today and Wednesday. The next lot of weather in store for the country is going to be warmer but wetter as air from the sub-tropics is forecast to move over the country on Thursday and Friday.

“Expect to see the temperatures increase from mid-week, getting into the mid-teens for most, and I wouldn’t be surprised to see some places up north and in the east of the North Island reaching 20C,” said meteorologist Emma Blades. Overnight temperatures are also going to be mild, with cloud cover trapping the warm air in.

Areas of low pressure and frontal features within the sub-tropical air mass will be bringing bursts of rain for most northern and western areas during Thursday and Friday and for the South Island into the weekend. “We are forecasting the first lot of heavy rain to hit the west of the South Island overnight Wednesday into Thursday, and heavy falls are also likely for other exposed locations such as Northland, the Bay of Plenty, and the Tararua Ranges towards the end of the week,” said Ms Blades.

In relation to winds, sustained northeasterlies are on the cards for Auckland for the rest of the week. “For eastern areas we are forecasting bursts of strong northwest winds on Thursday and Friday, especially for Wellington and the Wairarapa, so do check in on our severe weather updates,” added Ms Blades.
