Hawke's Bay residents will need extra blankets this weekend with particularly cold overnight temperatures.
A high pressure system with southwesterly flows will bring fine but cold weather to the region.
MetService meteorologist Sarah Haddon said showers that have been hanging around Hawke's Bay over the last few days had slowly eased and were expected to die out today due to a low pressure system moving away.
This meant that most of the southern parts of the region experienced sun yesterday, she said.
There will still be a little bit of cloud, rain and wind off the coast but this would improve by the end of the weekend.
"There's strong winds in some exposed places getting up to 50km/h.
"Most of the region will be fine . . . there will be a little bit of cloud hanging around the Wairoa district."
The southwesterly flows today and tomorrow would be bringing some really cold temperatures with highs only between 10-12C and a low of 1C tonight and -1C tomorrow night, with probably even lower temperatures inland.
This cold air and clear skies will also bring frosts, Ms Haddon said.
On July 16, Napier recorded 0C overnight, but it was not common to get that low at this time of year.
"We do get temperatures like this sometimes when there's clear skies.
"The average minimum for July is 5C so it is definitely much lower than the average."
On Monday, a developing northwesterly will bring warmer temperatures and some high cloud to the region with highs increasing to mid to late teens until Wednesday.
"It definitely makes a different where the air is coming from."
A complex low was expected to develop over New Zealand on Wednesday.
This was still a long way off so it was hard to tell how it would affect Hawke's Bay but the weather should start to deteriorate, she said.
