incorrect. No-one has forecast rainfall today. You are getting mixed up with tomorrow.


i saw plenty of forecasts that said today.

im guessing they didnt know if he rain was going to be here before or after midnight.


If you go by WZ's forecast, it will often forecast the rains the day before. Not sure why they do it but it's something I have found over the years.

This is going to be a real drought breaker in some areas on the north and mid north.

Perhaps less so in the riverland, but fingers crossed.

The forecast was correct. The city got 40mm of rain before 9am today. Rainfall is measured from 9am-9am, not midnight.

I'd never even realised that haha.
It is a weird system when you look at it, given only 9 hours of rainfall are actually included in the actual "days" rainfall numbers, and the remaining 15 hours are included in the next day. I suppose its really just a 24-hour total, but we are trying to assign it to a specific day.

I'm guessing the reason 9am was originally used was so that people didn't have to go an read gauges at midnight, before automatic gauges were introduced.

it appears when tweaking GFS someone had their hand on the
wrong knob.
maybe it's what things will look like with exessive global
warming.
lots of pretty colours though......

hey TH.... its due to the old GFS being phased out... the model is struggling with the changeover to Fv3.

ok thanks tek, there was obviously something going on, be
interesting to see how much of an improvement this will be,
surely it would have gone through extensive in-house tesing.
so a couple of more points, will BSCH still be ok? and what
about the gfs high resolutiin website?

some pretty classy zombie showers out in the gulfs atm.
slowly heading se with the emphasis on slowly.
maitland in the firing line of one and the fleurieu another.
they appear to be somewhat convective in nature.
be interesting to see if they hold their integrity over land,
if they do someone is going to get a good drink.

Yeah, I noticed the odd "not moving" rain radar echo in the morning, was still there in the late afternoon after I finished work and had a look. Just hanging out over the middle of St Vincents Gulf. Is there a meteorological explanation?

Lack of shear aloft which is lower in wind speed than what is normally seen. A bonus if you are directly underneath one and can pick up a healthy total.

Probably some flash flooding in the creeks near Cape Jervis today. A pity the cell missed parawa aws.

Very cold here these last few days. Keep seeing heavy cloud cover in the arvos capping temps around 10-11 and then rapidly clearing in the evenings with frost before midnight most nights. Plenty more cold nights to come as well. Relentless. Bring back the rain

hit Naracoorte just before sunrise, all the grass verges
and lawns were covered in 'snow'.
-ve 3.8 not too shabby, even the fog was thin and looked
like frozen smoke. more like smog from all the wood fires
around. even this time of morning the only breeze to be
had is from the odd clandestine sparrow fart, the smoke
from blackened chimneys lingers like a pub patron at
closing time. another plant killing mongeral tonight.
happy days
