Dixie Chicks fans are optimistic that the weather will favourable when the American music country band plays at the Mission Estate on April 8.

With the long-range weather forecasts for this weekend looking reasonably good, many are harbouring the notion that weather tends to run in seven-day cycles.

"Oh I wouldn't go with that," Metservice forecaster Andy Best said when that forecasting angle was broached.

"We are a bit beyond old wives' tales these days."

Mr Best said Hawke's Bay was caught up in the typical "changeable season" and the earliest stage they would likely have a fairly strong idea on how April 8 would turn out was at the end of the coming weekend.

He said the changeable nature of autumn, coupled with the unpredictability of building low pressure systems, made it difficult get a completely solid handle on weather patterns.

It was a "complex" spread of low pressure systems currently around the country which had brought the rain in, and while there would be an easing of it on Tuesday showers were set to return, and increase, on Wednesday.

But from there on things were looking good with sunshine returning on Thursday along with temperatures in the mid-20s as the main low edged southeast off the North Island.

The weekend, at this stage, is forecast to be a combination of clouds and sunshine.

"Although there is another low approaching off the Tasman," Mr Best said, adding that meteorologists would be watching its progress accordingly.

The temperatures were mild due to weather systems being drawn from the northwest and the tropical waters of the coral seas.

Mr Best said he would like to put the minds of the estimated 20,000 people holding tickets for the Mission Concert at rest but at this stage could not.

It was a case of "wait and see."
