I spy with my little eye something beginning with the letter "T" for the end of this week.

The GFS prognosis (cooor dont i sound flash!!!) indicates some very cold air aloft for thursday and friday and this should lead to some action i reckon.

Action looks to be likely along a very sharp cold front followed by a SW pattern.

thoughts anyone?

Will be interesting to see what develops in the eastern Tasman over the next 12 to 24 hours with the pool of cold air moving through.
I see the Cold Front west of Buller this evening is very active just now with a good line of Thunderstorms along it.

Cool and drabby this morning.. SW change has arrived but this afternoon may tend interesting for something atleast with the trough line moving northwards from Buller at the moment.

Yesterday's strong northerlies turned to the south just before midnight here in Tawa, and brought much-needed rain. Nice and steady too, allowing the parched ground to make use of it before too much runs off. 21 mm since just before midnight. Last rain was 3 mm which fell on April 4th. Bit nippy, though!

Just had a heavy squally shower here with hail ( small)

Sat pic shows some larger Cb clouds developing out to the west.

Some good lightning activity and probably hail in this next incoming shower to auckland..

Saw a few strong flashes (east of Manukau) on my way home

A Thunderstorm passed just south of Auckland.

Also looks like some Thundery action over Northland and BOP currently.

Well we've had some very brief periods of heavyish rain in Kerikeri, but no thunder so far
