General December Weather

[Razor]

Looks like a volatile start to the last month of 2020

A picture tells 1000 words...

Wow

[Chris W]

Into December and...back into spring - the PV making its presence felt with a few bouts of westerlies before it allows La Nina control later in the month.

Yes. It's a bit like winter into spring, this year.
The last day of winter it got to 24C, then the next day, the first day of Spring, it snowed.
Climate change going insane

[melja]

Some short memories guys, early in the month we had over 25C 5 days in a row in chch.
19C in Auckland this time of year would be about a normal average.

Timing there, Mikey,
Today's maximum was just 17.8C. NE winds developing this afternoon and cloud moving in more to the along the foothills.
Easing this evening.

[Storm Struck]

Indeed I'm seeing about 3 thunder set up days coming in the models , a much better scenario we like to see for this time of the year.
It has been wet and changeable but not all that much for the city and the penninsula, just a measly 5mm yesterday while other areas got 15mm+.

[spwill]

Nothing for us but some dying fronts, humid next week which may support a better rain chance mid next week.

[mikestormchaser]

Latest for saturday shows thunderstorms set up Canterbury plains

[Orion]

Nor'west arch today and feels cool in the shadow of the overcast.

Blustery at times, observed dust flying around the foothills.

Presently 18.6°C.

Same here. up to 25C.

[NZ Thunderstorm Soc]

It was nice and clear and blue once the NW cloud cleared but now it it hazy looking towards the west.
Probably strong winds whipping up the dust?

[Chris W]

Wee shower in Kaikoura just now.

Saturday looks interesting, guessing heating is the main element at play as change looks afternoon-ish at a quick glance.

Editing as I walked outside half an hour ago to this overhead and in the distance:

No wind yet

[Razor]

Was a good blow here in ChCh for a couple of hours this evening. Off down country tomorrow to Paradise Station, then Kepler Challenge Saturday and home via Alexandra after that. Expecting a lot of wind.

[NZ Thunderstorm Soc]

A NW sort of day with NW Arch cloud moving across from noon to a fine sunny day, however as the afternoon wore on the sky becoming hazy with probably higher wind development. Today's maximum was 25.5C. NW winds picking up this evening from 9pm.

[NZstorm]

Very steep lapse rates over the east of the South Island on Saturday point to hail, possibly large. A limiting factor may be the moisture, need a proper onshore wind to bring it in.

Looks very warm for the north of the country early next week with high 20's temps possible. GFS indicates the warm advection will produce a lot of elevated storms in Tasman which will affect upper western South Island early week.

[spwill]

Temperatures in the mid to high twenties for a few days next week will combine with 18C dps upper North Island to give us the first real taste of humid weather for this season.

[Chris W]

Not a breath of wind in Kaikoura all night. Very warm start to the day, not a cloud in the sky.

[NZ Thunderstorm Soc]

A fine and sunny day with blue dome skies and a moderate to fresh westerly blowing for much of the day before turning more East/SE from late afternoon and then dying out this evening. Today's maximum was 24C.

[Chris W]

Looks a decent chance storm chance eastern SI tomorrow with time for heating, cold uppers and favourable DP. Moisture/southerly change from mid-late afternoon into evening.

[Orion]

Very pretty scarlet sunset sky in the south-west at the moment

16.0°C.
