Convective period, NI, 25-28th January

[jamie]

i agree Tim. i have been out on the hill watching things for the past hour. Things are really trying to our south but keep dieing. nothing has developed north of about Te Awamutu. Really hoping for something to develop here between now and 6pm so i can go for a chase tonight.

[Philip Duncan]

There's a light north east breeze over the upper North Island...think that's killing the conditions a bit

[Paul Mallinson]

Only for Auckland.

The NE is quite dominant here.....
There is a cell developing to the WSW here but looking North it looks too stable.

Hey Paul (or any other intelligent person who knows ),

What prevented the convection firing around the Auckland region yesterday? We did have a sea breeze convergence...

[phildan89]

Got some decent storms developing south of New plymouth near Stratford area. Loads of CG strikes out of them. Will try to get a few pictures of them...

[borris89]

thunder heard here in hawkes bay, plenty of instability over the ranges but the onshore breeze is blowing it further into the ranges rather than this way.

I love these..

Yeah we had the bullet, didnt have the gun to fire it thought. TT, Jamie & co pinched it down there way.
Sbz came through too early, uppers destabilized at the wrong time & they again they stole the gun to create their own PyroCb down Matangi way.. unfortunately all that did was piss a lot of Aucklanders off. Nice try guys!

[dogmelon]

There are two severe thunderstorm warnings on concurrently, big day today.

[Michael]

Sea to cold? Guessing as its happening over warm land.
