Forecast issued at 4:30 pm EDT on Thursday 30 October 2014.
A high pressure system lies over the Tasman Sea and extends a weak ridge across much of the state. During Friday the high is forecast to strengthen while a cold front approaches from the southwest, with hot, dry northwesterly winds developing between these systems over most inland areas. The front is expected to move through southern, western and central districts on Saturday with hot, strong and gusty northwesterly winds over much of the northeastern half of the state prior to the change. Some fairly widespread light rain is expected over the southern inland with this front, but only isolated shower and thunderstorm activity is anticipated for the remainder of the state with little rainfall and potentially squally winds associated. The change should move through the northeast on Sunday with milder southwest to southeast winds extending throughout. Current guidance suggests temperatures will increase through the west of the state again next week.
Forecast for the rest of Thursday
Fine and mostly clear. Fresh northeasterly winds near the coast before a weak southerly change in the south. Generally light and variable winds inland though tending moderate southwesterly in the south.

Freshening, dry northwesterly winds inland before a southwest change reaches the southwest border area at night.

A cooler, gusty southwesterly change extending through southern and western and central districts.
