LUX  Thanks for this very nice app.   
(Version 2.1.6)

DEMORAY  The developer's link is currently broken, even when I try to download it from their own site.

I've tried to get this app several times over the past year and every time there's been a problem with the download link.

Is it just me, or has anyone else had this problem?

IBEME  I really like this application and have had it sitting in my menubar for quite awhile now. Weather Vane is a good example of software that does what its designed to do, and does it very well and unobtrusively. Unfortunately, updating to OS X 10.6 seems to have damaged it. Specifically, once the preferences are initially set, they can't be changed. Likewise, the "About" and "Quit" commands at the bottom of the menu no longer seem to work. Since the program does display and update the weather and temperature this isn't a huge issue since I almost never change my preferences after setting them the first time--but I do hope this fixed in the next release.

HANDYMAC  Well, I like it. I've been using WeatherDock for the last couple years, and it's great, but it's really more than I need (with a really huge menu, even on a 17" MBP display), so I was happy to find WeatherVane, which provides the basic info in a small menu (and looks tasteful in the menu bar). If I need more, I can go to a weather service's homepage. WeatherVane does what it does well; if it doesn't do what you need, there are alternatives, but don't pan it just because it isn't as huge as other weather apps.

The only thing that puzzles me is that WeatherVane, which accesses its info from AccuWeather, consistently shows temperatures for my city up to 5 degrees higher than WeatherDock, whose info comes from Weather.com. (Don't have a thermometer at my house, so I don't know which is closer to my actual situation.) Of course, this discrepancy isn't the developers' responsibility, but it does seem odd.

JEFFREY HARRIS  Lame at best.

This is extremely limited. It seems that you're only able to display ONE city at a time... unless I'm missing something. The interface is poor.

If you're looking for a free, well featured and flexible weather app, check out WeatherDock.

FORMICA  I agree with PCHARLES67 -- Meteorologist offers more weather data (if you choose to display it) and superior control over that data. Weather Vane does offer a fair amount of data, but it only displays it in a tooltip box with tiny writing, and like almost all tooltips everywhere, it doesn't display long enough to read all of it (or perhaps I'm just a slow reader!). Furthermore, Meteorologist can show the radar image for your location, but I'm guessing that few people use that function because it's buried a little deep. You have to open the Preferences, select the Cities tab, double-click your city's name, select the Weather Items tab, then put a check mark in the Radar Image checkbox, even though the word "None" in the "Unit" column is greyed out, giving the impression it's not yet implemented.

Anyway, Weather Vane is nice, but Meteorologist is superior in every way.

PCHARLES67  This is an attractive application, but on a small screen it takes up too much space. I prefer Meteorologist because I have a lot more control over what I can display.  
(Version 2.0.1)

WEASELBOY  Just installed this on Mac Pro with 10.5.4 and it works well. I like the simplicity of the interface.  
(Version 2.0.1)

IDJSTER  Works well. Has Canadian weather, sits out of the way in the menu bar, it works as advertised. I really like this app! Very nicely done!  
(Version 2.0.1)

HAZMAT  Looks very nice, but the menu in the menu bar looks grayed out, as well as the days of the week in the menu. Very odd.
