I also use the BOM's Forecast Explorer for Vic (it's not available elsewhere yet). The predictions there are based on forecasters not simply an ensemble of model runs.

For satalite images I use MODIS. The 250m resolution great for snow extent (and floods) if there's not too much cloud cover although the quality seems to vary with every second day being better. You can down load the images with geo-referenced files so you import them in GIS as well.

There used to be a private AWS a little south of Jindy (possibly along the Barry Way?). Does anybody know if this is still working and have a link?

.

not entirely true, they use a program called Graphical forecast editor (GFE) , it imports weather model data, then they can change it based on what they think might happen, the text you see is automatically generated by GFE.

The best resource for MAP ARCHIVES is http://www.australianweathernews.com ...daily synoptic, satellite images and maps back to 1996 plus temperature extremes etc. Good to see the classic weather charts. So many links within this link also

Plus there is an unbelievable amount of information on the weather bureau's http://www.bom.gov.au in relation to historical records that no doubt gets overlooked... Go to Climate link on front page, fill in the record element u are looking for at any site in Australia and up comes the data set

Seriously cool; I like all that fine detail, which is unavailable from other representations of model data.

Going the other way (model data from satellite images) one of the prettiest images on the web is Jaxa's global real time rainfall estimate plot (here):

One to watch for those far-off systems is the NCEP GFS ensemble, here, including the famous spag plot (broken again...).

EDIT: Working again. I see we already had that one (in OP), but mislabelled.

I dare you to try and find that page by navigating from the base EC page.

Been looking at TWC Mesocast lately. It looks pretty good, but people don't really mention it ever? Is there something wrong with it?

I always look at mesocast..being the first model to update

It actually predicted the epic queensland floods very very well

The NCEP GFS ensemble 500z Spaghetti Plot listed in the OP draws a lot of queries. Here's a layman's attempt at an explanation:
<ol style="list-style-type: decimal"><li>Crudely put, this is a plot of atmospheric thickness. It shows two contours of the thickness of the bottom half of the atmosphere, starting from sea level - that is, contours of the height from sea level to 500mb pressure. (Atmospheric pressure is ~0mb at the edge of space and ~1000mb at sea level; but that varies across the planet, so &quot;thickness&quot; is a bit imprecise here. The so called &quot;thickness charts&quot; implement a more precise definition.)</li><li>The light blue lines are 5820m height contours and the red lines are 5940m height contours.</li><li>There are lots of each because this is a plot of an ensemble of runs. It shows the results from the GFS model run 42 separate times: 21 starting at 00z (midnight universal time) and another 21 starting at 12z (midday). The 21 runs comprise one using a best estimate starting condition (the &quot;control runs&quot;, plotted in brown for 00z and grey for 12z), plus another 20 starting from very slightly differing starting conditions.</li><li>This approach gives an indication of the chaotic nature of weather systems. Strongly divergent behavior over time would suggest highly chaotic conditions and therefore low predictability. It has been shown that appropriate consideration of ensemble behavior increases overall prediction skill.</li><li>Because our atmosphere is a free column of gas bound only by gravity, its thickness is proportional to its average absolute temperature. That is, PV=nRT (approximately, subject to the effects of atmospheric flow dynamics).</li><li>So contours of thickness are also approximate contours of average lower troposphere temperature. That's why the blue ones are mostly closer to the pole than the red - it's colder there, so the half-atmosphere thickness is less.</li><li>It turns out that a red contour extending to well north of our alps means it's usually cold enough to snow; a blue one means it definitely is. Of course, that doesn't mean there's moisture and appropriate instability to make that happen. But if there's a nice shape to the contours, there may well be.</li><li>The green lines are the average positions of the two contours for the time of year.</li></ol>
Feel free to correct...

This is a near real time wind model. Not sure what it's based on, but it's a cool rendering and allows you to move around/zoom in which is neat.
Found a great visualizer - multiple overlays - projections - global or local view - Google Earth like controls.

Very cool. Also does currents and SST anomaly.

Can step back up to one month (currents and SST, more for weather), and forward 7 days (weather only; click "earth"). Also can display the overlay value (e.g. SST) for a selected location (click map).

Data is from GFS / OSCAR / EMC; SST anomalies are vs 1961-1990. (Still incredibly warm off the south coast...)

Would anyone know what's happened with this site - ie the loop hasnt updated this year - SatAnim

Perhaps there is an equivelant view showing cloud development over a 24 hour period in a loop?

No, a few other people were asking about the weatherchaser and it seems he's disappeared.
