A week of two halves, first stormy then becoming settled

Yes a low pressure system offshore to the east of New Zealand will provide some stormy weather from today through till Wednesday, mainly for the east of the South Island and lower parts of the North Island. Then on Thursday and Friday a ridge from an anticyclone in the Tasman Sea brings more settled weather to the whole country, a weak front on Friday moving around the edge of this ridge brings some cloud and the chance of drizzle to the east of the South Island
however.

For today’s outlook in your region check out this morning’s
forecast here.

Tomorrow a low to the east of the South Island deepens a little and tightens up bringing rain or showers to eastern regions north of about Dunedin through to
Wairarapa. Rain may be heavy at times about the coast in Canterbury especially
Banks Peninsula and this could cause flooding issues into Wednesday about low
lying areas.

Little River comes to mind as a place that can be affected by flooding at times with these type of set ups so if your planning a trip over to Akaroa later tomorrow or on Wednesday it would be wise to keep up to date with
road conditions through the likes of AA Roadwatch or the NZTA’s Highway info page. Expect strong south to southwesterly winds, gale force about the coast, gales move into Wellington during the evening.

Southland and Central Otago can expect cloudy periods with brisk south to southwesterly winds. Mostly sunny on the West Coast and about Nelson with southwesterly breezes.  Mostly sunny for much of the
North Island also although a few morning showers clear about Auckland and
Northland.

The low pressure system still hangs about on Wednesday but this will be it’s last dash. Rain for Canterbury though to southern Marlborough, also Wellington and Wairarapa; expect a few heavy falls especially about Banks
Peninsula in the South Island then easing to showers in the afternoon with
strong to gale southwesterlies easing.

Mostly sunny on the West Coast and about Nelson with light winds, Marlborough sees sunny spells for inland northern areas with showers about the Sounds and right on the coast. Cloudy periods about
Southland and Central Otago with southeasterly winds, occasional showers about
coastal Otago clear in the afternoon.

Sunny areas and some cloud for much of the North Island with west to southwest breezes, a few further morning
showers about Northland and Auckland clear. In the afternoon strong southerlies
push into the Hawkes Bay and Gisborne bringing showers.

Thursday sees a sunny day dawn for all of the South Island as a ridge moves in, there is a
chance of some early cloud north of about Banks Peninsula however; winds will be
light. In the evening a weak front moving in from south of the country brings
cloud and drizzle to Southland. Mostly sunny weather for the North Island with
southwesterly breezes, a few morning showers clear about the east coast then
becoming sunny in the afternoon. There is the chance of a few straggler showers
hanging around into the afternoon about East Cape.

On Friday the ridge is mostly in control. Sunny weather for much of the North Island with light winds
and afternoon sea breezes, cloud later in the evening about the east coast with
a drizzle patch or two possible there overnight. In the South Island cloud and
drizzle patches spread north during the day along the east coast, mostly sunny
on the West Coast and about Nelson. Morning drizzle clears Southland with
afternoon sunny spells.

Just checking up on the latest on the ex-tropical due to make its way south near the end of this week.  I’m assuming its now heading away from us and less likely to affect us at all?

Correct.

Phil mentioned this in a video last Friday which you can view here: http://www.weatherwatch.co.nz/content/weather-video-autumns-cool-change

There
doesn’t appear to be any developing in the near future that may affect
the North Island, around mid March some lows get going in the tropics
but they look to stay up there for now.
