Tomorrow quite a bit of moisture will be coming in off that Northerly to NW flow pre front, could pop up some isolated Thunderstorms in the Waikato mid/late PM if sufficient heating occurs.

Might be a chance of a thunderstorm for eastern LNI Friday? Cold 500mb temps, surface convergence and daytime heating once the front clears? I have Friday off and wouldn't mind going for a drive

Yes, looking chilly upstairs across the North Island tomorrow with icy cb across the ranges and eastern areas.

I am heading for the South Island tomorrow and might catch a storm?

500mb prognosis 1pm Thursday.

You can see the moisture in Auckland this morning with some low based cumulus.

The set up over the South Island looks as far north as Timaru by 7pm and heading north into the evening.

Yes tomorrow actually looks better then today now. Models all over the place this year

"Cloudy mild and humid" here this morning, only 20-odd degrees but possibly because one has been busy (bright idea! get into town early!

) it feels a lot warmer.

Nice big Thunder clap just now, with a storm just north of Cambridge.

GFS nailed the convergence over the North Island today.

Today fairly useless. Too much upper stratus layers hindering the ground heating development.
Looks doubtful about any precipitation prospects as well ?

Just observed several flashes of lightning

to the west of us from home

Loud thunder to our east now! Frequent flashes and booms echoing round us.

Loud thunder over new Brighton here 10 mins ago. Three strikes and thunder coming from the west/nw. Just starting to spit with rain. Cloud bank going from nw to se. Overcast, light airs here. Wind starting to pick up from south as I type.

I see those flashes towards chch city and port hills from rolleston. Quite a keen SE wind to so probably that convergance the models were suggesting today. NZstorm got it bang on though! As he said at night.

Wind picked up a bit now. Very heavy rain shower passing through.

Richard · Unread post by **Richard** » Thu 22/12/2016 23:38

Had a flash here too along with a huge downpour.

petem8nz · Unread post by **petem8nz** » Thu 22/12/2016 23:41

Huge downpour now. Lightning activity still to west

Richard · Unread post by **Richard** » Thu 22/12/2016 23:55

25mm in the last 40mins,

Interesting developments in North Canterbury. Don't think we'll be so lucky to see a thunderstorm here but has started raining. Good call NZStorm.

Nice thunderstorms for about an hour in Rangiora, 18mm from it and up to 6mm this morning.

What incredibly good timing to get such a big dump of rain, ended up getting 47.6mm, will be interesting to find out 'who got what' in and around this area, i would say that it was a real hit and miss event going by the radar.

Very turbulent crossing of the Alps and also approaching Chch when returning from Australia last night. The aircraft windows were very iced up until mid-descent.

Quite nice to see lightning at night, just shows with it being December storms can fire up at anytime without heating and provided the right convergences are there.
In contrast weve had about 1mm here, spitting off and on today but 17c so with abit of afternoon heating there could be some beafy showers thunder and hail even across the plains not just inland.

Nothing observed from here. Wasn't expecting anything because of the boring conditions so went off to bed after posting on my blog
