"It's a fairly typical weather pattern for this time of year.
"We're not expecting for it to be anywhere near as severe as last week," he said.
"It is looking like there's quite a bit of fine weather, it's not going to be perfect ... there are a few showers about but that should be mixed in with quite a few fine spells as well."
The severe weather last week brought multiple mini-tornadoes, including one near New Plymouth that ripped the roof off a petrol station on Tuesday and another in Mt Maunganui that damaged houses, cars and schools on Thursday.
Wellington was also hammered by torrential rain and flooding.
But everything was returning to normal now for this time of the year, Mr Glassey said.
The cool temperatures over the last few days should rise and remain "pretty reasonable" until Wednesday.
After the front moved through on Friday, there was another southerly sitting behind it so people should rug up, he said.
"It has been a little bit colder than what it was earlier in the month because we had a southerly over the country but it is still pretty normal for this time of year."
