A slack pressure gradient could lead to some unstable weather over the upper North Island today meanwhile a series of fronts push northwards over the South Island during the day. Southwesterlies ease over the country on Tuesday after a windy start for some.

Anywhere from Auckland through to the Central North Island and across to East Cape may be in store for heavy showers this afternoon, perhaps even a thunderstorm then clearing away this evening. Mainly dry elsewhere. The South Island sees rain or showers in the west and south, dry in the east Canterbury northwards although a few showers may sneak into coastal Canterbury later in the evening / overnight Banks Peninsula southwards.

Shower activity clears for most on Tuesday morning however there may be a light shower or two continue through the afternoon and evening about coastal Southland / Otago and along the east coast of the North Island.
