General December Weather

[spwill]

Some distant lightning /thunder observed here around 1.30am with heavy rain.

[Richard]

Had 37.4mm so far, still might nudge 40 by the time this clears, a very useful rain.

Now what will Friday and Saturday bring in terms of cloud buildups.?

[melja]

52mm here and just gone over 1100mm YTD

I see a downpour has popped up in Sth Auckland, airport showing 19mm in the last hour... but dry here since 6am.

[spwill]

Unstable skies here with heavy showers, the heavy stuff should be east of here shortly.

[David]

Thunder heard in Howick

[NZstorm]

Heavy rain here and thunder to north.

[David]

Lightning and only a few seconds to the boom now

[Cyclone Tracy]

That line developed nicely for here. A couple of close booms and a quick fire 5mm.

[David]

Very intense rain from that here - up to 167mm/hr on the weather station. Total came to 13.6mm in 15 minutes.

The next potentially interesting storm set up is in the South Island on Saturday afternoon. A supercell possible on the Canterbury plains given 6km bulk shear upto 50knots.

The threat of elevated storms for northern NZ late Saturday appears to be subsiding.

Better get my 50km run across Banks Peninsula out the way in the morning then!

I've been looking at Saturday for storms, still looks interesting with some NE vs SE going on, unstable air and some directional shear.

What I wasn't expecting was the risk MetService have issued for tomorrow, because I wasn't looking at it and i was distracted by Saturday!

Not Bad.
A rather cold 12C for much of the day with grey overcast skies and drizzly showers.
Huddled around the fire this evening and tomorrow at 11:23am, is the Litha, the summer solstace, which means it's the longest day of the year with sunlight.?
That's global warming for you.
Can't wait until June the 21st, when, probably, I'll be sitting around in T shirt and shorts, sitting around the barbee, enjoying a few beers or two, with it beeing bright and sunny and about 20C in NW conditions
Climate change, I love it.

Think you'll find that our summer solstice is on Saturday...
(and our next winter solstice is on June 22).

62.6mm today might be a record for my station, operating just since the start of this year. 8mm before midnight also.

Yes, sorry, Nev you are correct on this...ooops

Cyclonic warrior EX TC Owen continued ability to survive dry air onslaughts is now starting to feed the atmospheric river poleward towards NZ. EC is now taking this into consideration on this morning’s 12z run which brings moisture to the NI earlier than projected a day ago. It’s also starts pushing moisture into the top half of the SI. This Christmas might be wet in parts of the SI as well as the NI if that verifies.

Another 'claggy' overcast and wet dull day.
Not much wind, if so from the south.

[melja]

Another 13mm yesterday evening to make 65mm in the last 3days, lawn very water logged.

Another 5mms in Halswell, taking us to 30mm for last three days. You will most likely be getting another drenching today Melja!

[Richard]

Had 9mm last night, 47mm for the last few days, and yes, more today.
You would have to go back years to the last time the countryside around here has looked so lush.

[NZstorm]

Potential there for some heavy thunderstorms/flash flooding in the north of the country 24th through to 26th. Plenty of model variability but the general synopsis is a 500mb low approaching from the NW and moving across the North Island during the period with subtropical moisture.

[NZ Thunderstorm Soc]

Hopefully the above event dosen't intrude on the fine weather forecasted here from Christmas Eve and Christmas Day as people down here want it fine and sunny after all that 'claggy' weather month, so far.

[NZ Thunderstorm Soc]

Amazing.
Today is the longest day of the year and the daily sunshine period is at it's longest time period t'wixt sunrise and sunset. Today being the longest day.
From 11.32am, it is now heading back northwards.
Just went outside and saw condensation on my breath.
12C and pouring down.
Can't wait until winter to put on my shorts and sit outside with the barbee with NW and 20C
