Covering period of Monday 30th June- Friday 4th July – It’s a settled start to the week for much of the country, with fine conditions expected across most regions, a great opportunity for some outdoor school holiday activities, making the most of the dry weather.
However, conditions are expected to deteriorate by midweek. A developing low in the Tasman Sea is set to bring widespread rain to Aotearoa. Stay informed and keep an eye on the latest forecasts as the system approaches.
Today (Monday), a cold front is currently sweeping across the South Island, bringing scattered showers and patchy frost. As the day progresses, this system will gradually shift northwards, delivering showers to parts of the North Island by the afternoon. The southerly flow behind the front will continue to drive precipitation across the south, along with keeping the overnight quite chilly.
Tuesday through to Thursday will bring more settled conditions as the cold front exits the country, making way for a dominant high-pressure system. However, a developing low-pressure system over the Tasman Sea is forecast to bring wet and unsettled weather to the North Island on Wednesday, with rain spreading into the South Island as the system intensifies on Thursday. Periods of heavy rain and strong winds are likely, particularly in northern parts of the North Island, including flood-prone and exposed areas, where thunderstorms are also possible.
MetService Meteorologist, Kgolofelo Dube adds “The possibility of a tornado associated with damaging winds should not be discounted, so make sure to keep an eye on MetService.com for updates.”
Heavy rain may also affect the upper South Island, potentially causing further impacts in already saturated areas such as Tasman and Nelson, where the risk of flooding and slips will be heightened.
Temperatures will continue to hover below 10°C in many areas, with overnight lows near or below freezing. This will lead to widespread frosty conditions and snowfall in several regions. Most mountains are already blanketed in thick layers of snow, and the upcoming falls will add to this, creating ideal conditions for ski enthusiasts. However, it may also pose challenges for travel, particularly on snow-affected roads.
The week is expected to end on a more settled note for much of the country, as the rain bands associated with the low shift off to the far east.
