"Oh, I wouldn't go with that," MetService forecaster Andy Best said when that forecasting angle was broached.
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.
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 today showers were set to return, and increase, tomorrow.
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.
"Although there is another low approaching off the Tasman," Mr Best said, adding that meteorologists would be watching its progress accordingly.
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".
