A front brings heavy rain to the upper North Island today in a similar set up to last Friday so keep up to date with watches and warnings from Metservice for this front. The South Island is more settled by comparison but could see instability this afternoon about inland hills and ranges, thunderstorms in other words.

Northland, Auckland, Waikato & Bay Of Plenty
Cloudy with showers or rain, expect heavy rain for Northland then as a front slowly moves southwards becoming heavy for Auckland from late afternoon or evening, torrential downpours possible then starting to ease overnight. From late evening or overnight is when Waikato and perhaps Bay Of Plenty will start to see heavy rain. Quite humid and muggy with gusty east to northeasterly winds, perhaps strong to gale about some exposed eastern coastal areas. Northland may see a few thunderstorms from late afternoon or evening, perhaps an isolated downpour and thunderstorm for Auckland overnight.
Highs: 20-23

Western North Island (including Central North Island)
Mostly cloudy and humid, chance of a shower in the afternoon. From evening rain starts spreading down from the north, north Taranaki may see heavy falls overnight. Easterly winds, perhaps tending to the south in the afternoon then east to northeast winds pick up again at night.
