Possible Storms South Island 3/1/13
Considering there's potential for storms for both the east and West Coast today and that its not associated with the resent wet NW flow,a separate thread is needed.
The signs look promising for my area with a NE wind blowing,if a westerly was to come up the chances of storms would then be zero,fingers crossed.

Re: Possible Storms South Island 3/1/13
If theres going to be a storm it needs to hurry up and happen as the upper level airmass is progressively warming over the South Island today. I am yet to see a good storm day when the afternoon upper level temperatures are in a warming trend. There looks to be a window over North Otago for some isolated lightning this afternoon but it doesn't look great.

Re: Possible Storms South Island 3/1/13
I would have thought convergence would be enough for todays set up, NE onshore winds against the colder southerly change later on.
I am actually surprised to see the NE this morning, i thought the SW would be still blowing especially up here but we have general main ingrediants anyway.

SEVERE THUNDERSTORM WATCH Issued by MetService at 02:33 pm Thursday 03 January 2013
Valid until 08:00 pm Thursday 03 January 2013
This watch affects people in the following weather forecast districts:
Canterbury Plains
North Otago
Dunedin
Onshore winds have triggered showers over the foothills in South Canterbury and North Otago. These are expected to continue and turn thundery from mid to late afternoon until early evening, and may spread into the Dunedin District. Any storms that form in this areas this afternoon have the potential to bring locally heavy rain and large hail with diameter 20mm or more. Large hail can cause significant damage to crops, orchards, vines, glasshouses and vehicles, as well as make driving conditions hazardous. Should severe weather approach or if you feel threatened, take shelter immediately.

Re: Possible Storms South Island 3/1/13
I'm in agreement with SteveW. Not enough oooomph today as the upper atmosphere warms.
Some Cu going up but only mediocris.
I noticed that most of the snow has melted off the ranges too on the way home from work this afternoon, that was there this morning.

20.7 degrees here at present; fresh south-easterly breeze; sunny; other clouds crossing from west.

Yes, that cloud is looking nasty! More frequent lightning-static, big drops of rain, just on the edge of it at the moment I think. Ha! A hailstone or two by the sound of it on the roof. (posting from phone )

Re: Possible Storms South Island 3/1/13
There is a fairly sharp upper trough just moving across the east coast of the South Island as this is written. Some storms have been generated in Canterbury, as noted here with medium size hail. There have also been some lighting strikes in the vicinity of Dunedin. Once the trough moves away, which should happen soon, everything will die down.
