A northwesterly airflow lies over New Zealand today, therefore temperatures in the east are warm, says a WeatherWatch spokesperson.
"An occluded front passes over New Zealand today moving in from the west meanwhile a cold front pushes onto the far south. Warm in the east today."
In summary, the weather for today is basically wet in the west, dry in the east.
On Sunday a ridge of high pressure moves in bringing mainly settled conditions.
"We still see some cloud in the west with a few showers although they will become few and far between from afternoon. Eastern regions are mostly sunny after any morning cloud clears," says a WeatherWatch spokesperson.
"Partly cloudy skies for the upper North Island with a few showers, winds from the north or northwest, morning rain for Bay Of Plenty eases.
"Winds change to the west late afternoon or evening. A few showers or maybe even some rain about Taranaki and Kapiti, a bit drier elsewhere in the southwest but there may still be a shower or two with northerlies.
"The east coast has high cloud, perhaps morning spots of rain then drying out, northerly winds," says a WeatherWatch spokersperson.
WeatherWatch advise that morning rain for the West Coast will ease to showers, with rain continuing about Fiordland before easing in the evening.
"Morning rain moves through Nelson and Marlborough then easing to showers in the afternoon and clearing. Dry in the east with high cloud and north to northwesterly winds, warm temperatures," says a WeatherWatch spokesperson.
"Some rain moves into Southland around midday, perhaps a few showers reaching Otago in the evening then rain or showers clears away."
In the week ahead
WeatherWatch advises that a low may bring strong winds and heavy rain on June 29
"A low moves near the upper North Island on around the 29th June, this could bring strong southeasterly winds with a chance of gales about some coastal parts,'" says a WeatherWatch spokesperson.
"Heavy rain could be an issue too, if this occurs eastern Northland, Coromandel and East Cape are the most likely candidates to receive the heaviest falls."
