Looking like a another nice day for Auckland to finish the month.

Some airmass destabilisation in the Bay of Plenty this afternoon with a low topped thunderstorm or two and small hail on the cards.
Possibly as far west as eastern Waikato. 500mb -28C.

Todays isolated thunder risk a bit further west than we thought. Hunua ranges this afternoon?

it looks to be building SSE towards me. However we have very dry air here unless a sea breeze kicks in soon. So I don't expect it to live very long if its tapping into dry air.

Interesting day considering thunderstorms were not predicted for the area.

Previous runs of the gfs were placing the CAPE in the Bay of Plenty. But turns out it was much further west over Auckland!
We had a 500mb vorticity lobe right over the tops of us which would have helped with lifting the air.

It's OK John :lol: we will get our turn. You can't beat a Canterbury thunderstorm day with a good severe set up on the plains.
