This is a Weather Monitor running on the system tray. OK, there were already quite some examples on the forum but this one is working worldwide as far as I know.
It's a pretty old script that I wrote last winter and it's running on my test server since almost 7 months without any interruption, and is still doing fine. As it never crashed, it's obviously stable.
So, it could be the right time to publish the code now...

What does it do:
Displays the weather from right to left in the currently active Windows Title bar:
Actual weather Brussels: Mostly Cloudy 16°C - Relative Humidity: 57% - Visibility: 9.99 km - Wind: WNW 6 kph - Pressure: 1023 mb, steady...
Afterwards, it restores the original Windows Title

Or if there is no Actve Window open, it displays a TrayTip containing slightly more information:
Actual weather for Brussels, BE:
Conditions as of 8:00 pm CEST
Mostly Cloudy 16°C
Relative Humidity: 57%
Visibility: 9.99 km
Wind: WNW 6 kph
Pressure: 1023 mb, steady
Sun, 21 Jun 2009: Low 10°C, High 18°C, AM Light Rain

If HistoryFile=1 in WeatherTray.ini, each time the temperature, cloud cast or humidity changes, it will register the change in a csv file
11/06/2009, 04:31, 12°C, 94%, Fog
11/06/2009, 05:47, 12°C, 94%, Mostly Cloudy
11/06/2009, 06:02, 12°C, 88%, Light Rain
11/06/2009, 06:47, 11°C, 94%, Heavy Rain
11/06/2009, 07:17, 12°C, 88%, Mostly Cloudy
11/06/2009, 07:47, 12°C, 94%, Mostly Cloudy
11/06/2009, 08:03, 12°C, 88%, Light Rain
11/06/2009, 08:48, 12°C, 94%, Cloudy

Tested on Windows XP and Vista
On Vista, the scrolling message doesn't function as there is no identifiable title bar, the traytip always works.

Source of the weather data:
RSS Feed of Yahoo
where BEXX0005 = the code for Brussels, Belgium

More information at

How to find your City:
Example for New-York
- Goto http://weather.yahoo.com/
- Search for New-York
- Select Brooklyn
Resulting url:

USNY0176 is the code for New-York, Brooklyn

The RSS Feed is:

How does it function:
The script has been designed to consume as less memory as possible.
In sleep mode, WeatherTray consupmes about 980K-1.300K
In fetch and display mode, it requires 2.500-4.000K (just take a look at what your MSIE is eating from your resources)
It can thus stay on your tray without effect for your other apps.

Any defined number of minutes, the script will wake up and fetch the latest weather from Yahoo RSS and display it.

With a mouseclick on the icon, you can also force the TrayTip if you like
You can also exit via the icon.

The csv file will always contain the name of the City as shown on Yahoo:
Weather History Brussels.csv (for Brussels)
When you change the City in the ini file, a new csv will be created.

Content of ini file:
There is no editing module of the ini file. So you will have to take notepad and edit it. I have no intention to write

[Yahoo_RSS] ==>this is the Yahoo sections header
url=http://weather.yahooapis.com/forecastrss?p= ==>The url of Yahoo RSS without the city code
Town_code=xxxxxxxx ==>The City Code
Degrees=x ==> C = degrees in Celsius, F = degrees in Farenheit
will also convert respectively km to mi, kph to mph, mb to in
Display_frequency=## ==> Display The Weather every x Minutes
HistoryFile=# ==> 0 = Do not keep, 1 = write history to csv file
If option is set to 1. a csv file will be created in the script directory.
Every change (Temperature, Relative Humidity, Sky) will be saved
Show=Wind,Visibility,Humidity,Pressure ==>Show items in title bar scrolling message (the longer, the slower
Country: display country code
Humidity: display humidity information
Wind: display wind wind information
Visibility: display visibility
Forecast: display forecast next day
Pressure: display Pressure information
This last items is also optional in the tray too because 'sometimes' the result will be 0 if degree Celsius is selected (due to a bug in Yahoo!)


Useful? Probably not :huh:
Funny? Only when it rains ^_^
Should you put it on your desktop? If you can't lift your head and look outside the window, maybe you should... :lol:

Enjoy it
