I use the meteograms as a guide to weather conditions at Siding Spring Observatory (Coonabarabran NSW), every few months or so (when I get telescope time). Last time I looked (July) the meteograms showed the US 7-day and I think BOM 3 and 7 day. Now only the US 7-day chart is available. Is this permanent?

Probably the best guide to likely clear skies is RH - it is frequently foggy on top of the mountain even when not down in Coona. Failing that, likely rainfall. What's now the best place on WZ to look for RH forecasts (or rain) over the coming several days?

Thanks

Hi Fracto

For discussion and information on the meteogram issue, please see this thread

In the meantime, you can access the computer model forecast charts here

Thanks, I had seen both, though it wasn't clear to me exactly what will eventually be available or when. At the moment the BOM charts at http://www.bom.gov.au/australia/charts/viewer/index.shtml provide better information - at least for RH - (found via the thread you mention).

Fracto, try this ECMWF site. ; Siding Spring mountain
Or select "Advanced map".

Cancel all "European" boxes and select required R.O.W. box

No idea if it will be of any use to you!

Timed out with edit!

For meteorograms go to;

NOAA's Air Resources Laboratories

Enter Lats and Longs ie; "Siding Springs" Lat and Long [ Southern Hemi Lats require a minus sign before them to be viable and not be located in the NH.]

Follow through from there and you will get the required WV / Humidity and etc, meteorogram by canceling "Default" and selecting the required meteorogram or a multiple of meterograms.

Wednesday should see them ready. You might also care to check out the WZ Opticast forecasts for Coonabarabran at http://www.weatherzone.com.au/nsw/cw-slopes-and-plains/coonabarabran/detailed-forecast - this gives 3-hourly forecasts for DP from a weighted average of all models.

Fracto, once you get to the URL above, click on "Detailed hourly forecast" and it brings up an even more detailed meteogram which includes cloud amounts at low, middle and upper levels based on humidity at various levels. The text section below the graph also gives more cloud information than I've seen in any other meteograms on the web.

Fractonimbus,
Another very detailed weather map which is used by many glider pilots is Dr Jack's Blip Map which as it is winter and no flying down here with cold, wet winter [ at last after 15 years of bloody dry and droughts! ] i clean forgot about this particular forecasting tool.

This is the NSW version

You will find local cloud forecasts and all sorts of wondrous goodies here and with your background you should be able to sort this lot out.

Blipmap home is ; http://www.drjack.info/
