GFS handled today's storm set up well, apart from the fact it came a bit further south than it was showing and ruined my outdoor work day! 13mm here this morning.

Thunderstorm walloped us here, unusual for us to get one this strong... Thunder is house rattling volume! Also had a gust of 76 km/h with heavy rain and small hail :D

Not a lot to report from here. Pretty much a single short sharp shower at 4.30am. No thunder lightning, strong wind gusts or hail observed.

In the North Island a low risk of thunderstorms extends east of the moderate risk to include Bay of Plenty, the ranges of Gisborne and Hawkes Bay, and the Tararua District.

A trough is expected to brush past southeast Wairarapa mid to late morning and there is a low risk of thunderstorms associated with this trough.

No thunderstorms expected elsewhere in New Zealand during the period.

Got woken by the thunder overhead at midnight. I had my camera and tripod already set up to go but by the time I got outside the storm was moving on. Nothing else to report from overnight. Looks like the cold pool largely passed south of Auckland.

I was a bit annoyed I fell asleep last night and missed the bulk of that storm! My intention was to stay up for it.

Yes, it was pretty willing through the southern reaches of Auckland with a short, sharp CB squall with associated lightning and instantenous thunder around 0330. Certainly an early wakeup call for the household!

Wow big hail. We had hail in the night but sounded like pea size. That size would make a racket on the roof.
