More thunderstorms and possible tornadoes 20-21 May

I have just realised my average wind speed of 80km/h recorded last night is my station record. Not bad few days when you set new station record wind gust one night then a couple nights later max average wind speed.

the fact the baromter is a bit lower than modelled means the winds to come could be a bit worse than forecasted

Yes, I have 990 in Glenfield. 13.6 degrees, just a half-hearted breeze, very dreary-looking indeed. Must go stash the wheelie bin in the carport somewhere where it's not likely to blow into the car.

Here's a follow-up report showing the apparent tornado damage in Kihikihi, just south of Te Awamutu last night. Wonder if it might have been a microburst?

Chanced upon today some apparent further tornado damage in Puahue district, about 10km East of Kihikihi. Corner Parklands and Mockton road. In the second shot there are some uprooted pine trees in the far distance.

So you observed rotational damage? It wasn't straight line wind damage.

a narrow path of destruction like that means a tornado
and Face book posters said they could see the funnel cloud (there was a good moon light)

I didn't go so far as to try to analyse if things had fallen in differing directions, but it seemed the damage path was very narrow but severe. It wasn't like there were little twigs down all over the district.

Here is a zoom in of the background in a line behind the sign and two close broken trees. Just one or two pine trees uprooted in that grove.

all points to a tornado
not sure why members of this forum want to always say, nah, it will be straight line winds
(which do not produce a narrow destruction path that goes for a long distance)
