Latest 00Z NZWP soundings shows unstable air to about 3000m, which explains the passing showers.

A few heavy showers around Ak, I see any storm activity over Waikato has been very isolated. I think this cloudy showery weather is killing our thunder chance.

Did a small local chase. Got some torrential rain. Couldn't drive in it. Torrents of water running down the hills. Got some good structure. I'll post the photos soon.

Sharply contrasting temps in upper/central NI this afternoon between warm northwesterly and cool southerly change, no doubt a big reason for the storms.
