Today sees plenty of thick high cloud, morning fog possible about the Waikato then breaking away. The North Island is mainly dry although there is the low risk of a light shower or two during the day about some northeastern exposed coastal areas from Bay Of Plenty through to eastern Northland.

Some rain or showers for South Westland, easing by evening. Spill over rain or showers spread into Southland and Otago for a time in the afternoon / evening.

Rain or showers for most regions on Friday, heavy for a time in the morning about the northwest Nelson area then later in the day about some parts of the upper North Island. Areas of rain in the east tend to be a bit more scattered and comes in the form of “spillover” rain from the west.
