General November Weather

[Richard]

Yes Jase there will be a severe drought if this heat keeps up,great for the garden though

Cooling down now 23C,cant see it going any lower 18 with this NW blowing.

[Orion]

13.6 degrees, the lightest possible drizzle blowing with the fresh to strong southerly breeze; overcast low uniform grey cloud; visibility maybe 800 metres. One of those days that's neither "useful, ornamental or diverting" so far.

[snowstormwatcher]

Overcast here as well sitting on 14.5 degrees. Should be much cooler today than the last few days. Fine up in Tekapo and Twizel so should be warm inland today.

[Tornado Tim]

Looks like a Low-Mod risk of some storms popping up tomorrow around Western Waikato (Waitomo).

Seems to be some shear too

Upper air temps are bit fickle though......

[Tornado Tim]

I looked at the radar and a storm developed over the Gisboune ranges with pink at its core!

A Thunderstorm Warning has now been issued on it:

Keep an eye on the Tokoroa Boltek as that is the closest, he needs to bring in his ranging a bit more but yet it can see the storm well.

I can see that cb from Auckland! The trop is still around 12km, so very high topped.

[jamie]

wow that thing looks nasty on radar. popped in on the 55" HD tv and zoomed in.

[tgsnoopy]

Doh, I was working at Whakatane Hospital and had no idea. Never mind, too busy to chase anyway. In any case, my desire for storms should be satisfied in just a few days time.

[jamie]

looks to be weakening now. hopefully someone out there got some photos. i imagine it would have looked very nice from the highway.

looks like i need to reset the lightning detector at my parents place. has not picked up a single strike in days.

[spwill]

Looked a very nice Cb from Auckland, too distant for a photo.

[Philip Duncan]

Shame radars aren't free so we can all watch

[Manukau heads obs]

could see it from here at one stage too (in between passing cloud)
but was hard to make out through the salt spray haze etc

[tich]

Could be interesting (or should I say dangerous) for trampers in the Ureweras.
A bit of drizzle overnight/tomorrow morning should be the grand total of the southerly front moving over us in Chch.
