Wednesday’s national forecast – Unstable North Island (+8 maps)

A low pressure system brings potentially unstable conditions to the North Island today meanwhile a ridge means it’s calmer for the South Island with a few clearing showers.

The South Island sees a few clearing showers about the place today otherwise it’s mainly dry, the North Island on the other hand has heavy showers and possible thunderstorms with hail for western regions. These clear away this evening, the east coast sees a few showers also.

No particularly strong winds today although about northern Northland westerlies become a little gusty then changing southwest this evening. Temperatures in the late teens or early twenties for most, mid teens for some inland areas.
