Two low pressure systems are affecting New Zealand this weekend but neither are overly troublesome, but on top of the wet winter isolated slips may still continue in some areas with the most set in rain.

The low in the South Island is dredging colder air and gloomy conditions into the eastern side and also the lower North Island.

Meanwhile the other low in the Tasman Sea is tracking towards Northland bringing much milder weather to the upper North Island.

The low in the Tasman will cross Northland on Saturday bringing a period of rain and showers to the North Island, while conditions dry out more in the east of the South Island (but remains cool). Sunday sees drier weather in many areas, although rain or shower may linger in the east of the North Island.

Next week starts out mainly dry ahead of a classic spring cold front arriving in the South Island on Tuesday and the North Island on Wednesday bringing a several day blast of windy westerly quarter winds.
