sure is a nice unstable picture over the tasman today, which is slowly moving towards us
remember when whangerie got deluges of rain from orographicly forced CB lines in warm and very humid northerlies some years ago?
something similar could happen?
very high DP here now for the time of year!

16/17C dewpoints , feels like summer .

Some showers to cross the area shortly, looks like the heavy stuff will pass west of us.

doubt we will get 25 today

doubt we will get 25 today

Has clouded up with the Front moving across but with the high dewpoints the temp will move up very quickly in any afternoon sunshine.

Few showers about this afternoon.. dewpoint up to 19C!!

Man its hot!!! It's 28C in my part of town!!!!

Just between you lot and me, I spotted some Castellanus clouds up around the lower - mid deck at about 1.30 pm.

From what i understand this form of alto/cu is a precurser of instability etc etc.

Yes, there was some Altocu castellanus there today. I think that was part of the warm front which brought a few heavy showers to Auckland this morning.

i can see a nice looking CB top in the last of the setting sun out to the west....reminds me of that distant CB at sunset in the midwest we saw!

Upper air is more stable over NZ today than it was yesterday with warming aloft over the North Island and cooler surface temps over the South Island. Still looks to be a low chance of thunderstorms along that frontal boundary though.

Been on this forum 2 years as of today .
Humid,warm,and moist out there at the moment overcast at times but some sun making breif appearances with occasional spits of rain.
Light NE wind after a strong SW wind came through around midnight last night also currently 19C.
Certainly quite a few ingrediants there for thunder at the moment just unfortunate models disagree.
There was a Tsunami warning in place yesterday for Japan and the Pacific a magnitude 8.1 quake occured but was then cancelled later on.

Probly explains all the 4 and 5 quakes on the scale across NZ in the last 48hrs.

the caifornia coast did get wave surges that caused strong rips and caused some damage in some locations..

Warm enough here to melt an Iceberg.
Temp only in the low twenties but our dewpoint temp is 18C, very sticky.

looks like they are getting usefull rain in north and east otago.....which is a good thing to see in developing el nino at this time of year
(maybe it wil be another claytons elnino?)

And that rain has reached here now was light all of a sudden turned heavy with some quite large drops so more a west coast rain really.
Temperature is up and down too went down from 19C to 13C before now back up to 16C with heavy rain.
EDIT.. Not sure but I think I just heard thunder to the west sounded like it but nothing on tracker probly just hearing things .
Edit again.. it is thunder just had another rumble in the same direction rain getting heavier too.

Rain eased back now to just light falls and the sun is trying to come through still a light NE too.
Few strikes here and there on tracker now even a few in the canterbury region in the direction i heard it from before.
The latest radar below shows how isolated to the north it is not sure if it is heading south or out to sea I would say out to sea.
6mm of welcome rain in about 40mins.
Thunderstorm near Westport too at the moment.
Cheers
Jason.

Thunderstorm inland now going by tracker and certainly more active out there now.
Still getting some heavy bursts of rain off and on.
There was a blue patch in the sky before too I could see towering CU towards the west .
Where is everyone .
Cheers
Jason.

Looks like a concentrated storm there Jas... Going off?

Yes there seems to certainly be a storm out there only thing is I can't see the storm due to middle layer cloud and some lower clouds.
Certainly saferics on the radio and the tracker is picking it up well too perhaps as it gets abit more darker i will be able to see flashes.

That lightning is in the Alps, north of Mt Cook through to the Kaikoura ranges.

Lightning visable in the sky not far from here to the sw
Cheers
Jason.

I dont think so! Some thunder heard here over the last 2 hours, but as Jason says, too much lower level cloud to see any storms. The odd heavy shower passing over, rainfall rates peaking at 40mm/hr, 16mm total so far.

Really?, thunder must be able to travel a long way since I am hearing thunder in christchurch. Wrong this time, mr know-it-all.

Sorry, the lightning is through the main Alps but also looks to have been a storm over the Culverden area or there abouts. Nothing in the Kaikouras.

It doesn't matter anyway, there isn't much to it.
