Well done on the halo picture Graeme. I must have a try at capturing a Halo myself. There has been quite a few halos lately.

I see NIWA are predicting a disturbed W to NW flow over NZ for spring with wet conditions in the west and dry in the east. I guess this is just the usual spring regime for NZ. I'm not sure about the prediction for dry in the north though. Auckland has a West Coast climate. The rain will always make it north in a disturbed westerly pattern. Average spring rainfall would be a more likely estimation for AK. I think the summer will be dry in the north however.

That photo makes me wonder - when does a cumulus turn into a cumulonimbus?

Ben,
The cuform is defined as Cumulonimbus as soon as it shows signs of glaciation. The glaciation process is associated with the precipitation formation process (atleast in our lattitudes).

Any cuform that is precipitating is also defined as Cumulonimbus. Hense it is possible to get some very low topped cb's, especially in cold polar airmasses.

They dream down in Wellington that we are so far north (it would be wonderful if we were 15-20 S latitude)to miss the westerly belt and probably generalising it to the BOP and central regions like Taupo that is ok in WSW streams ;)

Month(S)!? I thought it was warm at the end of June and the 1st few days of July down that way when NW conditions prevailed?

One News got the high right for Ashburton today a chilly 7 degrees,with low cloud and drizzle.
Yesterday Ashburton missed out on the low cloud that plagued the coast,it was almost a scorcher for winter.It was a great day for a Bbq.
Are hoping for some snow on Mt Hutt tonight and tommorrow morning!.
Cheers.

They seem to be able to say when our hottest week is of the year and theyre right and it cools down but in the likes of Britain currently they probably said that 2 or 3 weeks ago but its gets hotter
