A cold southerly wind change spreads northwards over central New Zealand during the latter half of Thursday, with cold air in the upper atmosphere making conditions unstable. There is a low risk of thunderstorms over much of the South Island from Westland and Canterbury northwards during the afternoon and evening, although the risk diminishes from the glaciers southwards and south of the Rakaia River by evening, as depicted on the chart. A low risk of thunderstorms then spreads to southern parts of the North Island with the southerly wind change from evening, as drawn on the chart. Meanwhile, a front preceded by a strong northerly flow moves eastwards over the North Island, bringing a low risk of thunderstorms to eastern Bay of Plenty and northern Gisborne/Tairawhiti during the afternoon and evening. At night, a trough is forecast to move onto western Waikato from the Tasman Sea, bringing a low risk of thunderstorms there. There is minimal risk of thunderstorms or significant convection elsewhere in New Zealand during this period.
