Upper North Island
Morning showers clearing then sunny areas increasing, southwesterly winds tend gusty southerly then ease later.
Lower North Island
Morning showers and a chance of small hail in the west clearing then sunny areas develop, breezy southerly winds. About Wellington expect wintry showers for much of the day with a chance of small hail and snow flurries to 300m, clearing in the evening. Winds strong to gale from the south about the Capital. The east coast sees very coastal wintry showers with gusty cold southwesterlies, snow flurries to 300m. Some parts tucked in away from the coast like Napier and Hastings may see a mainly dry day, spots away from the coast about the Wairarapa may see shower activity for much of the day however.
Upper South Island
A sunny day for the West Coast and Nelson with south to southwesterly winds. Fairly cloudy in the east however shower activity will be very coastal, sleety showers right on the coast or perhaps even only Banks Peninsula for much of the day with the chance of a snow flurry or two to sea level this morning, snow flurries sticking above 200m otherwise. Expect gales on outer parts of Banks Peninsula.
Lower South Island
Cloudy areas with cold southwesterly winds, the odd wintry shower about with a few low level snow flurries, possibly to sea level this morning. Dry areas during the day also.

Wellington forecast wrong – as is Metservice’s, though they may be amending it now. It has turned SW/SSW, winds much lighter, clear and sunny. Now that there is a stong El Nino developing the “southerlies” often do that trick, which occurred only rarely in the previous 4-5 years.
