RainWatch – Tuesday 02nd January 2018

A light northerly airflow lies over New Zealand today, flowing around a large high centered well east of New Zealand in the Pacific Ocean.

Most parts of the North Island have the chance of a shower today, but there will be many dry areas also. The chance of showers increases for inland areas during the afternoon / evening where heating and converging winds could lead to heavy downpours and possibly even thunderstorms. Showers ease later this evening. I would try to be more specific but the nature of these showers is often quite random and hard to narrow down too much.

Most of the South Island is dry this morning, just the chance of a light shower for North Westland and parts of Nelson / Marlborough. This afternoon the shower risk increases for inland areas north of about South Canterbury, showers will be quite isolated in nature so many parts may remain dry. But for areas that do see showers there is the risk of a downpour and perhaps even a thunderstorm. Showers activity clears later in the day / overnight.
