Subtropical airflows and windy nor’westers are about to move through New Zealand over the coming days and weekend and this will bump temperatures above normal for this time of year, especially at night. 

Low pressure in the Tasman Sea means some rain and shower activity is likely this coming weekend.

The mild airflows looks to giveway to Antarctic air on Monday for the lower South Island. This is not locked in but is showing up in both your local forecasts and long range computer modelling. We’ll keep tracking it – but today we take a look at what is possible. It looks short lived too – with likely more windy westerlies arriving next week across NZ.
