These drizzly days are keeping the rainfall totals ticking over, but not really sure if they're doing much to help those that really need the rain. I haven't been up to my property near Mannum to see how I've fared up there, so no idea what has fallen out that way. Probably not too much due to the rain shadow effect of the Mt Lofty Ranges. Hope to get there July 27.

Yer I'd say not too much rain in that rain-shadow area Werner, few showers getting over the hills once in a while and a few from up the river south at times there in the past month, but would be struggling a bit I'd reckon...let us know how you go

Oh..,A little bit of action for the SA ers'

Late sunday the 28th July a precipitation signal appears on ACC g over the southern region.
And intensifies into monday the 29th July

A tropical dip in isobars at the surface layer.
Combined with support from a weak 500hpa trough
at the 200 hPa layer above ,a tad of convergence as some minor sub polar wind streams converge with a strong sub tropical jet.

Bit of a dry period now before the SAM crashes negative again - large slow moving high, good gardening weather at least. SST's warmed a little off NW WA and cooled in the western Indian whilst warming in the central Indian....dare I say Indian modoki like...but may cool again when SAM goes negative. At the same time the giant high will at least push moisture into QLD but how far west that gets is the question...it would be nice to have a big front push in and be able to grab some pacific moisture at the end of the cycle.

TS :cool:

HO HO Ho.. Something cold brewing..
re..ACC G 160hr forecast

http://www.bom.gov.au/australia/charts/ ... fresh+View

Agreeing with 'JS' and 'didjman' in the VIC thread. We have a decent cold pool forecast to arrive around the 8th August for South Australia, Adelaide vicinity. This will be its first port of call.
532 thickness encroaches on to the mainland , as far north as Port Augusta later in the evening.
A deep low centred off west Tassie, jam packed' with moisture.
Tighter isobars on this western flank likely to bring strong on shore winds.
This should be good. :D . 8-)

Low level snow quite likely.

Mount Lofty is the coldest location in the Adelaide area; during winter months the temperature may not exceed 3-4 °C on some days. The summit is the most common location for snow in South Australia; rare snowfalls sometimes occur in other parts of the Mount Lofty Ranges, and in Northern South Australia.

Possible..Grampians western VIC as well
