What models are you reading? the latest GFS run i just looked at has the THK levels down to as low as 521 overnight sunday/ early monday with -7C for the 850mb temp.
Problem being of course the lack of moisture and low dewpoints #-o .

from here: http://wxmaps.org/pix/aus.fcst.html It was the 12Z update, they have the 0Z update up now

It only has 24hr steps but I like it as it covers such a large area, I know there are better ones out there for NZ but I still like my old links. :B You can see even at 0Z on Sunday they are now going for -6C over a large area of the East Coast of the SI. Lets just hope it comes off! Moisture is going to be low but still with temps that low you can't expect that much, still I don't want much! and I know I wont get much here. ;-) :lol:

Seems like another low is coming up after this dominating high, LOL
Why couldn't we get these lows greeting us in the summer? Then our thunder chances would have sky rocketed!

I am crossing my fingers that this spring coming will be a very unstable 1, LOL

I thought frosts would be likely in many places Wed/Thu mornings, even light frosts in parts of Auckland, but the forecast temps seem to suggest even Hamilton won't get down to 0? 0_o

Yes, thats the thing that irks me about NZ's climate. The summer months are heavily dominated by anticyclones.
And when we do get summer instability there is no shear.

We may be heading for a La Nina. If that happens it points to a settled mild spring but an unsettled summer.

A moderate to strong NW has started to blow here, a sign that a SW change might be on its way,

Had a hail shower here this evening but that should clear away as the incoming anticyclone moves closer to us with some fine frosty weather for much of this week.
Should be mild this WE but not much weather coming up according to models, but then that could change, as another low lurks in the seas in northern waters.

Heavy showers here throughout the night, rather persistent at times looking at the line developed on the radar. 13mm since midnight. Backyard is completely saturated now as infiltration has stopped occurring in some areas which doesn't normally happen there. That would be done to such a wet May and start to June. Hints that a subtropical low will form early next week. I have a very impressive model run that popped up a day ago that ill post later today sometime cause I thought it was rather unusual

This subtropical low due on Fri/Sat looks pretty impressive on MetVUW's GFS map this morn. ECMCF now also in agreement. ...

The latest run just through shows the possibility of that 2nd subtropical low meeting up with the southerly front early next week which Blue skies have had snow forecasting to very low levels ("200m or lower") for a few days now

Good. The next anticyclone could be quite severe, ie.1040hpa plus so it could push up the severeity of a cold blast from the south as it moves towards the south of NZ.

If it givesus yet more substantial rain - the last thing we need after a lengthy wet cloudy spell - it's not good in any way at all.
