Sneak peak for the weekend's weather

This weekend the North Island will continue to get showers at times but there will also be sunny spells and dry weather in the mix, perhaps a focus on showers being a little more frequent in the northeast and along the east coast north of Hawkes Bay. The airflow will be from the northeast, temperatures will be reasonably mild with frosty conditions very unlikely.

On Saturday in the South Island many places look to be cloudy in a northeasterly airflow. Drizzle patches at times with a chance of rain about the Kaikoura Coast, long dry spells also in many regions. Southland and South Westland should remain largely dry though with sunny spells.

On Sunday damp conditions are more likely to shift to the West Coast and about Nelson, drier out east as the flow turns more northerly.

Tomorrow is looking very much the same as it has been today about the country, a bit wetter north of Hawkes Bay along the east coast and about the Bay of Plenty in the evening however.

Heavy rain continuing in the hills and ranges of Gisborne and Hawkes Bay through to Saturday morning
A slow-moving low to the west of the North Island is directing a moist east to northeast flow over the country.
Rain is forecast to continue in many eastern areas due to this flow, with further heavy falls expected about the hills and ranges of Gisborne and Hawkes Bay through to Saturday morning. A further 80 to 120mm of rain is possible in these areas during this time.
People in these regions are advised to be aware of rising rivers and streams and watch for localised surface flooding and slips.
The warning for the hills and ranges of the Tararua District and the ranges of Nelson west of Motueka is downgraded to a Watch, as no widespread heavy falls are expected, although further rain is likely

Thanks Derek!
