Front, Lightning possibilities West NI/SI, 12-13th Jan.
Looks like theres going to be plenty of lightning out to the west of the country tonight, it could well affect Taranaki as it moves SE.
Also, I'm wondering about the possibility of elevated storms with that warm front crossing Northland this evening.

500mb chart for midnight. Upper ridge over the north will steer Tasman Sea convection SE away from Auckland. Notice the contrast in upper level temperatures between Auckland-9C, New Plymouth-17C.

Re: Front, Lightning possibilities West NI/SI, 12 Jan.
I see that M/S has put a Mod risk for severe thunderstorms in the mid coastal region of the NI which carries the potential for a damaging tornado.
New Plymouth would be the hotspot I would imagine....
Id expect a severe thunderstorm watch to be issued this afternoon.
I have attached the 12 Z sounding from WP, very strong upper level winds going on atm..
It seems any storms in the coastal regions will be quite fast moving..

Hi, does anyone know of any online webcams located near the areas likely to be affected by this system? Cheers.

Niwa's Raglan Webcams might be good, although they are 2/3 ground: http://www.niwa.co.nz/cam-era/raglanRogue wrote:Hi, does anyone know of any online webcams located near the areas likely to be affected by this system? Cheers.

Re: Front, Lightning possibilities West NI/SI, 12 Jan.
So that dropped like 13mm in about 10mins. Just beat a 2008 rain rate record by over 10mm/h.
Have not had a night time squall like this since jan or feb 03 or 04 when the big floods were.

Re: Front, Lightning possibilities West NI/SI, 12 Jan.
Lost a tree last night and also 1/4 of my giant pumpkin plant. Might have said goodby to my chances of winning biggest pumpkin this year.
the tree also fell ontop of a parked up digger which is no good

Re: Front, Lightning possibilities West NI/SI, 12 Jan.
I would suggest that heavy rain like that sort of adds force to the wind behind it for trees
plus the ground is relatively wet

Re: Front, Lightning possibilities West NI/SI, 12 Jan.
Woke at just on 3am to a distant roll of thunder to the north east of Wellington. Looking at Trevor McGavin's site in Lower Hutt, he detected a significant number of strikes around 2-3am

Have not heard anyone else mentioning the thunder and lightning though. Maybe it passed though north of the Hutt?
Would be great to have access to the data from MetService to be able to see the track of the storm, both after the fact, and ideally in real time. We can only but dream it might happen one day!

Re: Front, Lightning possibilities West NI/SI, 12 Jan.
Yes Lightning did well increase on the squall line down further south around 2 AM but rapidly disintegrated when it hit land. Does look like it was north of the Hutt, seems that oregraphic lifting might have played a fact in squeezing out the last bit of lightning due to extra forcing there.BeaconHill wrote:Woke at just on 3am to a distant roll of thunder to the north east of Wellington.

Re: Front, Lightning possibilities West NI/SI, 12 Jan.
Just had some heavy showers pass through Palmy and a thunderstorm that developed to the SE, with five claps of thunder heard. This thunderstorm only seemed to start firing as the band of showers were being lifted across the Tararua ranges, which ties in with what Tim was saying earlier.Tornado Tim wrote: ... seems that oregraphic lifting might have played a fact in squeezing out the last bit of lightning due to extra forcing there.

If this front hit the north island at peak day time heating then wow it would have been a cracker.

Re: Front, Lightning possibilities West NI/SI, 12 Jan.
T-storm Warning for Kapiti Coast:
Not very lightning active but oh well its what M/S considers to be a severe thunderstorm.
Courtesy of M/Sissued by MetService at 05:10 pm Friday 13 January 2012.
Valid until 06:00 pm Friday 13 January 2012.
This warning affects people in the following local government areas:
KAPITI COAST, UPPER HUTT CITY, PORIRUA CITY and SOUTH WAIRARAPA.
At 05:00 pm, MetService weather radar detected severe thunderstorms near OFFSHORE KAPITI COAST.
These severe thunderstorms are moving towards the southeast, and are expected to lie near UPPER HUTT and KAITOKE at 05:30 pm and near THE AORANGI MOUNTAINS, TUTURUMURI and RUAKOKOPUTUNA at 06:00 pm.
These thunderstorms are expected to be accompanied by very heavy rain and damaging wind gusts.
Very heavy rain can cause surface and/or flash flooding about streams, gullies and urban areas, and make driving conditions extremely hazardous.
Very strong wind gusts can break branches from trees, damage roofing, and make driving hazardous especially for high-sided vehicles and motorcycles.
A Severe Thunderstorm Watch remains in force for KAPITI-HOROWHENUA, MANAWATU, TARANAKI and WANGANUI.
Not very lightning active but oh well its what M/S considers to be a severe thunderstorm.
