LATEST: MetService has issued a snow warning for the Desert Road, as parts of the country woke to a chilly morning on what is often considered to be the last day of spring.
Summer may be beckoning but a disturbed southwesterly airflow has interrupted the move to warmer weather.
Showers on the Desert Rd over the central North Island's central plateau may turn to sleet or snow this morning near the summit, MetService said.
It did not expect any snow to accumulate on the highway.
MetService also warned of a low risk of thunderstorms about the North Island east coast from Tolaga Bay to southern Wairarapa, and for Hawke's Bay, Gisborne and possibly eastern Bay of Plenty.
In Wellington the temperature was not expected to top 13degC today, after managing to get above 20degC on the five previous days.
The forecast maximum for Christchurch was 14degC, for Timaru it was 13degC and for Dunedin just 12degC.
Along with showers, Hawke's Bay was also in for a drop in temperatures, compared to the highs in the mid-20s the region had previously this week. Today Napier was not expected to get above 17degC, with Hastings to get no higher than 15degC.
MetService duty forecaster Peter Knudsen said the lower temperatures were due to an outbreak of cooler air coming in from the south of the country.
Such events were not unusual at this time of year, and the cooler air was expected to be gone overnight.
