In comparison with the last few days it was slightly more comfortable today, although still warm for a south westerly on 25C.
Some mid level instability this evening too, and also drove through a steady shower around Motukarara.

Should be some patchy welcome rain tomorrow but also very humid I bet with temperatures in the late 20,s.
Tuesday afternoon still looking ok for thunderstorms from early afternoon.

A fine day after a fine night and not as warm as yesterday with today's maximum being 24.8C with an easterly sea breeze.
Clouding up later this afternoon and evening.

Thunder over rolleston at 4am this morning..surprise wake up call. About 5 flashes observed and very loud thunder

Maybe an isolated storm for Waikato today, more active south of there like yesterday.

We got quite a few good CGs out of this cell yesterday afternoon as it came out to the coast at Tongaporutu. Today has much the same feel about it, so we might get a repeat show later on. Right now it's already too warm and humid to be outside & there's not a breath of wind. Feels almost tropical.

Up to 28.5 here a moment ago during a sunny spell, reckon 30 is easily achievable this afternoon if the cloud cover can reduce a bit more

Must reach 30 on my station today, surprisingly have not so far this summer. I did clear and repaint the screen in October and a flowering climber has blocked off direct line of sight to neighbour's roof which I suspect was radiating heat at times, the new neighbours have not cut it back like the previous ones did every spring.

The official sites must see some change over time with trees growing and new buildings going up etc in a bigger version of what I might be seeing.

Today certainly is very muggy with the rain this morning, and still the odd spotty shower now but 26C.
We might see some isolated heavy showers return from late afternoon.

MS seem to have a focus on the risk of storms for Canterbury for tomorrow morning rather than afternoon. The SW does arrive around 8am but most of the surface moisture isn't there until lunchtime onwards.
Isolated thunderstorms should form but it might not be until 12 to 1pm.
Also picking hail to be in the 10-20mm range, just with such an abrupt shift in upper temperatures and lingering humid air.
Snow down to 1500m even Tuesday night.

Has reached 31.0 on my station despite some cloud cover. Warmest day since 2022. Hamilton aero was up to 29.8 now. New Plymouth 28.8 with a Westerly wind is notable.

29 degrees now in CHCH with a 30kmh NE. Humidity high at 60%.

We will be holding out for some rain next couple of days as everything is parched around here!

Impressive storm developing just west of Waimate here. Constant thunder.

Starting to rain.

The air feels like it's made of steam.

Maxed at 29.1 here at 1.30pm then became really cloudy. Dewpoint was up around 23 at the time and less wind than yesterday so certainly felt hot outside

Cloudy with some rain overnight but easing before dawn with a NW Arch and sky this morning.
Becoming a warm day with light winds and some stormy looking cloud forms along the foothills this afternoon, probably resulting in that thunderstorm near Waimate. 30C the maximum for today.

I hot humid day for Canterbury plains temperatures around the 29 degree mark. Some mid level instability around this afternoon and reports of thunderstorms in south Canterbury.

Tomorrow If there's still enough surface moisture around with the southerly change may trigger a thunderstorm on the wind change but I'd warrant it a low risk.

Here is a collage from a friend of mine of the thunderstorm that hit at 4 34am on Monday. Right over the rolleston township

Southerly just beginning to drift in the windows, cloud filling in, lowering and approaching.
17.2°C now, 63% humidity.

And the first drizzle arriving with a brief gust from the south-east.
17.2°C, 64% humidity.

The end of the current hot spell, Auckland airport with an average temperature of min19.5C-max 28.1C for the previous 7days, dewpoint was often around 20C.

We didn't get another thunderstorm yesterday in the end but instead saw this very cool example of iridescence.

That's a great example

Hopefully an interesting day coming up being smack in the middle of a moderate risk area, sun now coming out and winds are light.

Sunny and windy from the NW here so far, the wind change to the south and east not making any progress inland.

Nothing of interest here, just rain, Off the Barkers shortly.
