Awesome :D _b

Nev are able to explain to me what conditions causes and/or creates the fog (or is low cloud) to come in like it did suddenly today over the bay, I still find it amazing how quickly it came in the way it did... and is not something I see to often, anyway will welcome any explanation, thank you.

if it was anything like what we saw at brians place at the auckland area meet, it was probably just a very humid incoming air mass. the cloud layer essentially lowered to the surface.

I can only hope 2010 doesnt pan out like this with the "thunderstorm events"
All of this stupid cloud cover is doing my head in....... :banghead:
I think this year was even worse than 2008, LOL
I may end up watching storm chasers to compensate on the lack of thunder i have been receiving. :lol:
I think im getting withdrawal symptoms >_<

Yeah quite a let down. Drove up to Huntly and all we had was one heavy-ish shower. It's pretty disappointing that a moderate risk of severe thunderstorms doesn't even deliver a single weak thunderstorm.

Todays sounding from Whenuapai. Some good low level instability with a lifted Index of -4.1 at ob time.

I think the issue today has been a lack of surface heating with too much lower level clouds.

I drove down to Bombay early afternoon , heavy rain/ surface water Pokeno to Mercer with a line of development running across the area giving the occasional heavy shower and thunder/ lightning for a time. Current radar shows more clouds building up down that way. A lot of cloud cover so not good for photo's today.

Took this snap on the way south early afternoon.

I noticed a photo of a landspout funnel on TV1 news tonight. I didn't catch the exact location it occurred.

The Met Service new website is fabulous. Easy to navigate except I can't find my favourite maps. Is it my blondeness or are there no thunderstorm forecast charts? I can't find them.

Below the 'rural' banner there is a small weather warnings link. Click on that.

Could be a very wet and cool day tomorrow, I don't think we'll get 20C. GFS is forecasting 50mm for Auckland.

Saw this in the Manawatu Standard tonight:

http://www.stuff.co.nz/manawatu-standar ... -farm-shed

There were heavy showers that passed through Palmerston North, around this time, with a wind shift from E -> S -> W. It looks like this was when one of the surface fronts passed through.

We also had moderate thunderstorms yesterday, on the SE wind change, which passed through mid-afternoon.

where is all this rain and thunderstorms for auckland and neighbouring areas going to come from?

good to hear tomorrow has better potential than today. i had a hunch the early convergence would stuff our chances by blocking the sun. oh well. ya win some and ya loose some.

A frontal zone slow moving across North Auckland is forecast to become more active during the day and drift south toward AK City.

Wow! Thanks Gregg. _b That's one of the best eyewitness tornado reports I've read for a while. Shame they didn't manage to snap a pic. :smile:

P.S. Just noticed the very last line on that story - must be a typo :-s
Most New Zealand tornados occur in the east of the South Island, or the west of the North Island.
