Revellers should make the most of a mostly dry New Year's Eve, because the weather is set to "go downhill'' tomorrow, forecasters say.
MetService meteorologist Daniel Corbett said things were looking fine in most places until about midnight.
"The brief fine and dry spell across much of the country during
the day on Tuesday and into the midnight hour will be short-lived as the next active trough spreads more rain and thunder across the country during the day on New Year's Day.''
There was a moderate risk of thunderstorms in Auckland tomorrow afternoon and small tornadoes were possible.
Strong to severe thunderstorms could also hit many western parts of the country during the day, with downpours possible in Northland.
