Yesterday's changeable weather of heavy showers followed by brilliant sunshine should calm today with a southerly change.

Today more rain was expected - but not of the intensity much of the region experienced yesterday, said MetService meteorologist Emma Blades.

This week is predicted to bring a lot of rain to the region but there would be a a respite midweek, Ms Blades said.

A southerly change would bring cooler conditions with temperatures of 18C or 19C, which Ms Blades said was "really chilly" for summer.

Today is expected to be cloudy as more rain falls across the country but conditions are expected to improve this afternoon with showers becoming isolated and southerlies easing around the coast.

She predicted there would be cloud cover tomorrow as a few early showers are on the cards, followed by fine spells with southerlies dying out.

Wednesday would see a welcome respite from the wet weather and the day should be mainly fine with developing northerlies.

Thursday is likely to see cloud cover increasing with northerlies freshening, and a potential for the wet weather to return.

By Friday there would be a high chance of rainfall as northerlies strengthen.

Black Barn events manager Francis de Jager said they did not let the weather dampen their 12th Open Air cinema. "Generally unless it's torrential rain we will continue. On Saturday night it was raining and we still had a lot of people turning up."

With another three showings this week, Mr de Jager said those attending the cinema should keep an eye on the weather, and if in doubt could ring Black Barn's cellar door after 5pm for updates.
