Monday’s weather outlook

Not a lot is going on in New Zealand weather wise for most of Monday, conditions will deteriorate later in the day however as a low in the Tasman Sea moves towards the western side of the country. This low combines with a cold southerly airflow which moves onto the South Island overnight.

For the upper North Island expect a mix of sun and cloud, a few showers move through during the afternoon pushing in from the west. Winds from the westerly quarter and afternoon temperatures in the low twenties.

A few showers affect Taranaki down through to the Wairarapa during the day, some may see plenty of dry also. Winds mostly from the west although tending southeasterly for Wellington and the Wairarapa. Overnight rain moves into western parts of the North Island with building west to northwesterly winds. High’s in the mid teens for Wellington, Wairarapa and the Central North Island. Jumping into the high teens for Taranaki.

Gisborne and Hawkes Bay is looking more promising with mostly sunny conditions and highs in the low to perhaps mid twenties. There is the chance of an isolated shower later in the afternoon or evening however.

A mostly cloudy day for many in the South Island especially along the east coast, there may be a light shower or two about with light winds from the southerly quarter. In the evening light showers turn to rain then becoming heavy overnight Canterbury northwards, the heaviest rain will likely be about North Canterbury and Marlborough. Temperatures across the South Island will be a bit cold tomorrow, most only seeing highs in the low double figures arena, Nelson however gets into the high teens.

Snow lowers to 1000m overnight for southern Marlborough, down to 500m or perhaps even 400m for Mid Canterbury then down to low levels for Southland and Otago (100 to 200m).

The lightest snow falls will be in the far south then progressively getting heavier the further north you go, but on the same token the snow level rises also as noted above.

A large high ridges deeply into the Southern Ocean on Monday ready to force some cold air out towards New Zealand overnight.
