Warm to hot weather will spread across all of New Zealand today, reports WeatherWatch.co.nz.

Under mostly clear skies and light winds highs will reach the 20s for most main centres with late 20s or even 30 possible through inland parts of the South Island.

Yesterday Alexandra again reached 30 degrees.

The crown forecaster is today warning of possible thunderstorms across the South Island interior.

“Inland areas of the South Island are likely to experience another warm to hot afternoon with quite humid conditions” says the government forecaster. 

“This is expected to assist the formation of convection over much of the higher land and inland basins and there is a low risk of thunderstorms being produced during the afternoon and early evening. If the thunderstorms occur, they should be accompanied by localised heavy rainfall with intensities of 10 to 20mm/hr”.

No other areas of severe convection or thunderstorms are expected.
