Corrigan said the Whanganui region would instead have a pretty dry week ahead, with very little if any rain expected.
He said the weather would likely be colder than last week, with overnight lows generally around four, five and six degrees for most of the week.
Corrigan said this was due to a southerly weather system moving up through the country.
"We've got a colder air mass coming up from the south and southerly or southeasterly winds flowing across New Zealand."
Especially low temperatures were expected over Thursday night, with a potential frost and temperatures as low as two degrees forecasted.
During the daytime, high temperatures were expected to be around 15 degrees all week.
Corrigan said these temperatures were expected for this time of winter, but they would be around two degrees cooler than the previous week's abnormally high temperatures.
He also said Whanganui residents should expect southeasterly winds, with the potential for the winds to be quite strong on Monday morning.
