With a La Nina we likely won't get a very dry summer like the last two.

Convection will be more possible as well as possible lows from the north.

I hear you Richard. Was out watering the lawn and the garden yesterday. The ground is rock hard! Hoping for 15mm or so tomorrow, anything less with the very mild weather quickly kicking back into gear by the end of the week is a rather worrying moving forward.

Hopefully the La Niña happens. Was a poor thunder season this year for winter. As predicted. But we should get some this summer though

We very much need this to be the case... Went into winter with a 250mm yearly rain deficit and have ended the season with a 300mm yearly deficit.

I see niwa is predicting normal to above normal rainfall for spring, here's hoping.

nice to see some action weather for canterbury (changeable spring weather/snow)
I wonder if the late SE change here tomorrow will cause some CB's :)

easterly wind change here already
barometer rising and the temperature dropping
its a wet high in the tasman though with a upper level NW flow making for tradewind windflow type showers still
looks to be a new low forming NW of Taranaki, but it probably will roll over up and onto northland

The all-time lowest September minimum for Christchurch of -4.4C may be under real threat come tomorrow morning - all the ingredients are there with a cold air mass, clear skies and light winds all in the mix...

Christchurch Gardens, which is generally a little warmer than the airport, recorded -4.8C on this day in 1919.

Thanks for that Nev - one would have to wonder what the airport would have recorded!! the -7.1C recorded at the gardens on 19/07/45 you would think would easily translate into a -8.5C for the airport!

A fine day today after yesterday's short wintry event.
Today's maximum was 12.5c.
Here's a photo of Mt. Peel which I took today.

Just looked at the GFS model run for sunday afternoon. Looks like an upper trough to cross over Canterbury sunday evening with a chance of heavy showers/ hail and maybe even a storm. Could be one to watch for.

Gosh the English Oaks are in a hurry this year. They usually do come out in September, but it's only the 3rd.Image
