Re: General July Weather
Yes that dropped global temperatures by 0.5C in the few years afterwards, that small decline in temperatures could have made all the difference in Christchurch getting 30cm of snow or hardly any in the August event...

Re: General July Weather
How many decent high pressure systems have we had this winter. 1 to 2? There seems to be a big absence of them so farm. The next 10 days looks warmish and wet across the country. In other words more of what we have already had so much of.

Re: General July Weather
There were some great looking winter CBs out to the west / northwest of Auckland during the afternoon yesterday, produced only a couple of light showers out my way.

Re: General July Weather
Last couple GFS runs have suggested some big falls for Canterbury ski fields Sunday - Tuesday..

Re: General July Weather
Interesting in tonight’s run that EC now has snow down to 100m on Thursday for Canterbury, only a few cms but still quite a surprise ![0_o 0_o](./images/smilies/0_o.gif)

Re: General July Weather
A few flashes to the west this evening driving home along Thompsons Track after attending a funeral in Christchurch, sadly dwindling away thanks to global warming or climate change whatever you want to call it.

Re: General July Weather
This morning observed a few branches down under trees in the Ashburton Domain: guessed the wind has been stronger than usual. It certainly sounded strong late yesterday.

Re: General July Weather
EC, UKMet and GFS are becoming quite volatile, trying to compute the flow on effects from the upcoming cold breach in the tropics this weekend. Fascinating to now watch how individual models comprehend the tropical disturbance. So far, from when the butterfly flapped its wings in the stratosphere a week ago, it has had all the ingredients of an upcoming major bomb cyclone in the region. We'll probably know if it will all come together by this time next week IMO.

Re: General July Weather
BOM, GFS and ECM all manage to keep the coldest air away whilst the latter two are bringing that nasty-looking low early next week. Volatile is definitely the word for the outputs CT!

Re: General July Weather
With the MJO also predicted to take a significant drop into negative territory over the next few weeks do you think August is ripe for a setup for something major to happen CT?Cyclone Tracy wrote: ↑Mon 23/07/2018 19:52 EC, UKMet and GFS are becoming quite volatile, trying to compute the flow on effects from the upcoming cold breach in the tropics this weekend.
