Home fires have been lit and heaters turned back on as Nelson wards off chilly spring weather, which is expected to linger into tomorrow.
Nelson forecaster John Mathieson said a large high-pressure system with origins "from chillier oceans well southwest" of New Zealand had established itself over the region.
A layer of much colder air lay above it and was expected to influence conditions, before the system headed east tomorrow.
It was responsible for the current unstable weather, Mr Mathieson said, with showers expected to form inland this afternoon and evening.
Tomorrow and Friday were expected to be fine and mostly clear, with a slow recovery from the recent cooler temperatures as the high shifted towards the upper North Island.
"Nelson will stay dry and mild on Saturday, with westerly winds developing, elevating temperatures a degree or two," he said.
Sea breezes on Friday would give way to inland westerly breezes, which would freshen from Saturday afternoon. Fine weather with patchy high cloud was expected later on Saturday, while Sunday was expected to bring a fine or partly sunny morning and firm sea breezes from mid-afternoon, with a cooler temperature as clouds gathered about the south and east hills.
The risk of showers would increase towards evening, with the chance of isolated thunder inland," Mr Mathieson said.
Monday was expected to herald a more settled phase of weather.
