Weather report.

Notice: this site was working last week, but now it is disabled. 07/04/2018



My stepfather was into meteorology. In fact, he was a weatherman in the military, He got us into it. So I like to look at a minimal weather report. Batch files make it easier for servers to display data as needed. Have an nslu2 running linux with very low resources. So a batch file is perfect for grabbing data off the web. You can also use it for mobile devices.  That also means you can insert the data grabbed into a database for later research,






Actually I have been doing weather scraping for a while, This is probably almost the tenth script I have written.  From the command line it might look like this:

~$ ./gwp2.sh 22546

The script to grab the data is fairly straight forward.  You pull the whole page off the web and then extract data as needed.

[code]
zip=$1
tmon=$(date +"%b")
tday=$(date +"%d")
echo "The weather for $zip on $tmon $tday:"
lynx -width 1000 -dump "http://m.wund.com/cgi-bin/findweather/getForecast?brand=mobile&query=$zip" > weather
cat weather | grep "Updated"
cat weather | grep "Observed"
cat weather | grep "Temperature"
cat weather | grep "Humidity"
cat weather | grep " Dew Point"
cat weather | grep "Wind" | head -1
cat weather | grep "Wind Gust" | head -1
cat weather | grep "Pressure"
cat weather | grep "Conditions" | head -1
cat weather | grep "Visibility"
cat weather | grep "UV"
cat weather | grep "Clouds"
cat weather | grep "Yesterday's Maximum"
cat weather | grep " Yesterday's Minimum"
cat weather | grep "Sunrise"
cat weather | grep "Sunset"
cat weather | grep "Moon Rise"
cat weather | grep "Moon Set"
cat weather | grep -A1 "Moon Phase"
cat weather | grep "Raw METAR"
[/code]

Note on arch linux use he -a argument on all the grep commands. example:

cat weather | grep -a "Raw METAR"

Hope this litte program helps someone.
