Another Groundhog Day for New Zealand with a repeat of weather conditions: Coastal clouds and warmer than average airflows leading to inland deluges later in the day with the risk of localised flash flooding, hail and thunder.

Generally speaking high pressure dominates New Zealand but a humid nor’east flow is helping spark inland downpours.
