On Tuesday we see heavy rain and possible thunderstorms in parts of both islands – as the week really fires up, weatherwise!

Rain and thunder is in store for the morning in the Bay of Plenty and other parts of the North Island, though the thunder risk is higher in the BOP than elsewhere. 
There’s a front moving from west to east, so Taranaki and Wellington will see easing rain first thing just before day break, but rain may not ease for the Central North Island until midday. 
Eastern Parts of the Bay of Plenty may not see rain ease till late afternoon or evening, while Northland and Auckland keep away from heavy rain in the morning.

In the East Coast of the North Island, there may be some heavy rain in the morning about the Wairarapa.

Early heavy rain eases in Marlborough from the morning.

Canterbury and parts of Marlborough – especially in the south – sees showers become heavy in the afternoon, before easing and clearing away later in the evening. 
For parts of Canterbury, from Banks Peninsula northwards through to southern Marlborough, there may be thunderstorms from afternoon also – then easing and clearing later in the day.
