Cold Outbreak behind a Low, 6th-9th

Low set to come off E'n Aus and only deepen really as it gets close to NZ, off about Farewell Spit. A high south of Australia looks set to be unusually strong and stationary.. will enable the jetstream to amplify nicely just west of NZ by Tuesday.

Snow to 300m at this stage over Coastal Otago.. flow looks a bit sheltered to effect Canterbury.. but the thunderstorm potential is there i'd say!

Certainly a week to watch for after a peaceful 2-3days latly.
Actually wasn't too bad today got to 24.7C under blue skies and a NE breeze shows it must have been NW inland not NW here yet though.
I can see atleast 2-3 thunder chances for us this coming week here's hoping atleast one pulls off 8) .
Wed,Thurs prob has a better chance but Tuesday night is one to watch for mainly heavy rain and strong winds though really.
Cheers
Jason.

looks like drought areas of NSW getting rain from the slow moving trough/low system over Aus ?
also looks like as it comes our way its going to stir up a bit a hornets nest in the way of beefy W/SW winds for a few days!

An interesting week ahead here's hoping 8) should be ok for fireworks I think the rain won't set in until atleast 11pm as latest radars don't depict too much to the south.
Warm and muggy day today under that thick high cloud sun breaking through at times with a few spots of rain. Was 26C at lunchtime now hovering around the 23-24C mark with a gusty NW wind.
Cheers
Jason.

We're now getting to the time of year when cold outbreaks are more likely to deliver major thunder and hailstorms as cold air air crossing warmer ground.
Southwesterlies are rather 50/50 for Chch, so we could get something interesting, or we might not. The far south, however, looks like returning to winter in a big way mid week.

If the sea breeze induced NE gets in the thunderstorms/hail will develop. Wednesday or Thursday. The central Otago fruit/wine growers might need some protection from the frost/hail!

May see a squally thundestorm as far north as Auckland although Taranaki south looks like getting most of the action when the cold air arrives mid week.

Fine night here for Guy Fawkes.

I think lack of moisture is usually the limiting factor for storms along eastern SI .
It will be interesting to see where TS develop this week.

Looks like a high risk of thunder/hailstorms about Southland extending into inland Otago on Wednesday.. risk of a few storms up north about Wed morning too. Still looking good for Canterbury I would think.. a cool easterly breeze may be enough to support tstorms ahead of the gusty southerly change.
500mb temp down to -36C Wed morning over Southland.. that's healthy! :)

Could be something up this way Wednesday night/thursday morning. Upper air getting around to a cool -35°C and 850 about -7°C. Tuesday will bring steady rain from mid morning, then ease during the day wednesday and return again during the evening.

Yes, should see some Thundery weather along SI Coast Lines Wends into thursday, air might be too dry inland.


Rather humid up this way today, our dewpoints have come up to 15C.

yeah totally, muggy as anything and summer hasn't even started!

apparently Bob McDavitt was saying that we're in for the hottest summer in a decade, anyone else heard this?

i hope by 'hot' he doesn't mean humid.....drives me up the blinking wall!

It's unseasonably cold and wet (about 8C with persistent rain) in Chch this morning, and it's not even a southerly. (airflow is northeasterly) There's even a road snowfall warning for the Porters and Arthurs Passes.
