In the extended forecast submenu, the text says "Mostly cloudy" (which I assume is correct), but the accompanying icon is a "Partly cloudy" icon. See attached image...
Can you provide the zip codes for the locations that are displaying the incorrect weather?
Assuming the PollockPines listed is referring to Pollock Pines California, Meteorologist is displaying correct information, it looks like OpenWeatherMap may have some bad data.
Just to be clear on what I was logging as the bug: The text and the icons
don’t match. The text says one thing (mostly cloudy) but the accompanying
icon indicates another (partly cloudy). Not sure which is right…

Also, I think the PollockPines reference is from someone else? A different
bug? That’s not from me; don’t know anything about PollockPines...

Hi, Harvey. Sorry for the confusion. The bit about PollockPines was meant for BobG.
OpenWeatherMap doesn't make a distinction between partly cloudy and mostly cloudy, so when I was making the new icons for Meteorologist I didn't bother to create separate ones and I rolled both icons into just the mostly cloudy icon for Yahoo Weather.
As it stands, that is actually the correct icon for mostly cloudy; the icon for partly cloudy just has one cloud (see attached screenshot).
I'll go ahead and re-enable the partly cloudy icon in the code.
OpenWeather is not responding to bad datta reports--can't even be sent.
But you can go to their world location map and zoom in on your area of interest.
There are actually very few locations.
But there is indeed one for Pollock Pines, CA.
At this moment the symbols look pretty good.
I think they may be using their own algorithms for forecasts. Their "radar map" is not actually a radar map.

The barometric reading from OpenWeather are apparently not corrected for mean sea level, so are usless as comparative weather data .
Currently South Lake Tahoe, elevation 6400', is shows 23.78"Hg-- it should be showing 30.83 "Hg.

Bob, good observation. It turns out that OWM reports both ground and sea level, YW reports ground level, while WU reports sea level. Up till now, I had not considered how they are used for comparison. For those of us who are not meteorologists, could you give a layman's explanation how the comparison is useful? I am very curious, thanks.

As one ascends into the atmosphere, the air pressure drops.
That is how altimeters work.
Landing aircraft contact airports for the current pressure to set their altimeters--so they don't come in to high or too low.
For weather forecasting purposes, all barometric readings must be mathematically reduced to standard sea level pressure for comparison with other areas-- as if all locations were at the same elevation. Weather maps are made that way.
In summer, I check the corrected barometer reading on the coast with our inland pressure. If my pressure is lower by a few hundreths of an inch, I know the sea breeze will come in and cool us down.
Otherwise, the heat hangs on into the night.

I have been watching Meteo with OpenWeather for a few days, but have shut it down again, because the data is completely whacky, and not consistant.
If OpenWeather's forecasts were 30% correct, CA would be out of an five-year drought and taking to the boats.
Barometric data is raw station data, and not corrected for mean sea level--so useless for comparison with other stations.

Thanks Bob for the explanation; I learned something today. Well, OWM does have both ground and sea level pressure, I just need to enable them. However, I wonder if sourceforge is becoming flaky (including the disappearance of the discussion forums). I am having trouble posting the updates, and I would really like to push out another version soon with fixes for the recent issues.

See here NOAA data of a few minutes ago for South Lake Tahoe, about 6400' el.
Setting pressure is the observed Station Pressure converted to standard sea level for comparison to other areas at different elevations. Pressure is always reported in this manner-- not the raw observation.
HG means inches of mercury, more correctly "Hg
SourceForge admins claim that I deleted the forums. I asked him what is the procedure for deleting them so I could be sure and not do it again. When they showed me, there is no way I did that without knowing it. They were trying to restore but I'm about to give up and start the forums over.

What a few clouds more or less amongst friends?
I'll see if something is wrong or if the data was just bad.

This afternoon it is NOT RAINING in ANY of these places.
Can you provide the zip codes for the locations that are displaying the incorrect weather?

Given the state of OpenWeather, Apple's built in side panel provides better current data and forecasts.
