“Summer wants you to know it’s not gone just yet, but autumn is coming with a bang with this southerly coming in.”
He said Sunday’s temperatures were above average for this time of year.
Hastings hit a high of 26.4C, Napier 24.4C and Wairoa at 25.7C.
“Those temperatures are pretty warm for this time of year, the average temperature for the daytime max that you would expect in early March in Napier, Hastings is around 23C, 24C.”
He said Monday’s cold air originated from the southern polar regions and the Southern Ocean (Antarctic Ocean).
“The southerly wind is almost like an express for that air to come right up to New Zealand and be in charge of the weather for the first few days this week.”
Corrigan said the weather on Tuesday was expected to reach a high of 15C to 16C, and Wednesday, 20C.
He said it wasn’t typical for a southerly to bring air from that far south as quickly as what is being seen.
“If this type of weather situation were happening in winter, it’s likely that we would be seeing snow to relatively low levels, more than just a frosting on top of the higher ranges.”
Corrigan said Thursday and Friday would see temperatures climb back up, with Thursday expected to be 22C to 23C and Friday 25C.
