General February Weather

The humidity will rise in Auckland today.

Looking like the Aussie heat wave has triggered some elevated storms over the western Tasman, often see this from heat waves in Aussie. Perhaps some elevated storms could reach the west of the NI tomorrow but they can be hard to predict.

500mb chart for tomorrow showing a big thermal gradient. Bay of Plenty 500mb-4C, Southland -26C.

Could be the odd clap of thunder down south for my birthday tomorrow, but seems unlikely

Gusty SW came through around 6:30pm, from the gusty NW.
Not much change.

And with that warmth is smoke from Australia, a very brown looking sky this morning.

You never know: some odd clouds around Ashburton at present - low grey shreddy things to the west, "explosive"-looking one to the south-east; occasional spots of rain falling from goodness knows where

Big, dark cloud going up west of Chch now. Should be a good shower, maybe a rumble?

Cool cam.

A low overcast all day but Grey Lynn still managed 28.7C.

Could of looked interesting this afternoon but the NW kicked in and stuffed everything up

Low overcast and still to be that warm is something so foreign to us down here, never get it anything like that.

I think I heard thunder in the last few mins. Not sure what it was but was a rather loud rumble.

Yup Elevated Thunderstorms over the west..... might keep an eye out west as they will be quite spectacular if the carry into the night......

Flip the base of those Elevated storms in Tasman is 4.5 KM ASL, Almost 500hPa!
The Blitzortung Amplitudal Waveforms are very strong, Lightning not so frequent, but with 4.5KM of air acting as an insulator, one heck of charge builds to overcome that.

Would be quite the sight to see a strobing cg coming from the base of the cloud to the ocean (providing its rain free).

Looking like some elevated storms heading for Waikato.
Some nice photos from Dunedin today.

Your post from last Wednesday there, Razor - just wondering how things are today?
