This week will be dominated be an east to southeasterly airflow between a departing low that is currently moving over Northland and an incoming anticyclone to the south of the country. Generally speaking eastern areas of both Islands will get cloudy wet weather for the week and the better weather will be out west.

In saying the above Otago and Southland should remain relatively unscathed as the main area this southeasterly will flow is north of these regions, Wednesday looks to be the day where it may be a bit damp in the far south.

Tomorrow is the start of this pattern but it won’t be in full swing yet meaning western areas of the North Island will still experience a few showers during the day, sunny breaks to however. Most of the lower half of the North Island should be wet. Also western places north of Greymouth may also get some wet weather which should clear early Wednesday.

Needless to say from East Cape right down through to Mid Canterbury it is looking damp tomorrow for sure. Heavy rain at times along the east coast of the North Island and possibly about Marlborough and along the Kaikoura Coast. Rain will ease off a little on Wednesday but it will be another wet day north of Mid Canterbury along the east coast of both islands, rain clears north of Mid Canterbury for the South Island on Wednesday evening.
