Relief from pollen-laden wind arrives this weekend and dry weather is predicted for the Magpie's first Mitre 10 Cup game today.
MetService meteorologist April Clark said before dawn scattered rain would lift to a cloudy day, with the inclement weather returning for a late afternoon encore, by which time McLean Park in Napier would have emptied after a 2.30pm kick-off against the Southland Stags.
A complex low-pressure system was moving across Hawke's Bay from the west over the next two days, leaving low-pressure systems behind it, she said.
Sunday would start off fine but rain would develop in the early afternoon as northeasterlies swung to the south as the front departed.
The maximum temperature would be 15C on both Saturday and Saturday with a minimum of 7C.
"It is cooler, because there is more cloud about during the day, but also pretty mild overnight because the cloud helps keep any heat from radiating away," she said.
"This is quite different - the low sticks around until Monday when you will have scattered rain with southerlies."
Monday's maximum temperature would be 13 C.
"Tuesday is looking a little bit better - we are predicting the rain will ease and the southerly with it."
While the chill wind was gone the winter temperatures were not - Tuesday's maximum temperature would be 12C with a chance of frost overnight thanks to clear skies.
The overnight ambient air temperature was predicted to be 3C which could mean zero ground temperature for some areas.
"We usually say if it is 3C or below there is potential for frosts - so it is possibly a light frost overnight Tuesday through to Wednesday morning."
But before the Bay breaks out its bud burst protection she said to recheck the weather forecast.
"With these dynamics - a complex low - things can change so we definitely recommend people check back because there is uncertainty with a complex system."
On-and-off rain is the very definition of spring for other parts of the country while Hawke's Bay usually experiences dry north westerlies. Those same winds carry pollen clouds to Napier and Hastings from upwind forestry blocks.
