Report of a 'Tornado' in Rahotu
Funnily enough I was thinking the possibility of tornadoes due to the low level NNW being over run by a 50kt WNW aloft.
You tend end up with good low level helicity in that wind pattern. I think the lack of instability put me off commenting on it.

Heavy shower here atm. I wonder whether some sea breeze interaction with the front over Northland this afternoon could trigger something thundery. A bit of a long shot but the moisture is there with 16C dp.

You had similar to us David. We had a rate of 110mm/hr but where i am milking it was even heavier. Heaviest rain i have ever seen in my life and ive seen some bloody heavy rain in my time. Wish there was a station on that farm to see what rate it was falling at. This farm is just out of Taupiri towards Orini.

The cold upper trough finally starts to depart NZ today but will have a final flick at the east of the North Island with a higher risk of thunder/hail in the Gisborne region today than yesterday. A few storms also possible in the eastern BOP given the development of an onshore flow there.

A warm airmass spreads onto the country Friday with 30C temps possible in the east Friday/Saturday. And then another polar trough heads for the South Island at the weekend but thunder potential looks uncertain atm.
