It's 2/3 of the way into the month, and temperatures are below normal over the greater part of NZ. Warmer weather may change that by the end of the month, but otherwise we could be looking at the first cooler than normal month this year.

Some thunderstorm risk showing for Friday, see how this looks in the modelling tomorrow. Bay of Plenty/Coromandel to Auckland up to Northland might be where the main risk is going to be.

Nice lightning shots on the TVNZ news this evening, possibly taken with the lightning app you can download on your phone. :smile:

Report of someone injured by a lightning strike in Dannevirke yesterday afternoon. There was a video on the Herald that captured a decent flash and thunderclap in Dannevirke too, wonder if it was the same strike?

A couple of photos of the storm over SE Auckland yesterday afternoon, formed on the convergence between NW and NE flow. More instability showing for northern NZ today, the instability more widespread across the NI tomorrow with the upper level cold trough.

Tomorrow looks like an interesting day around here with unstable conditions under cold upper level air and convergence setting up from Northland across Auckland down into Waikato.

A fine day here but with a bit of an NE wind blowing.
Today's maximum was 17.4C.

The dew point in Auckland is a moist 13C. See how good the convergence is today.

Looking ahead it is interesting the lack of westerly pattern in the model outlook given we are in full Spring now.

I guess the instability wasn’t strong enough today. Some evening drizzle/light showers here

It looked as though that there was thunderstorms in the North Island today??
Nothing on here.
Was there?
The Blitz showed some strikes. I don't know about MS/Transpower as you have to pay about $999.99c to join their site?? :rolleyes:
