For the weather create an image screen with this url:

file:///tmp/weather_map_satelite.jpg

Then create a separate script with one of these:

Weather radar NY

curl --silent "http://www.weather.com/weather/map/USNY1265" | grep "mapImg" | sed 's/^.*src="//' | sed 's/".*$//' | xargs curl --silent -o /tmp/weather_map_satelite.jpg\

Weather Radar TX

curl --silent "http://www.weather.com/weather/map/USTX0617" | grep "mapImg" | sed 's/^.*src="//' | sed 's/".*$//' | xargs curl --silent -o /tmp/weather_map_satelite.jpg\

Weather radar MA

curl --silent "http://www.weather.com/weather/map/ USMA0102" | grep "mapImg" | sed 's/^.*src="//' | sed 's/".*$//' | xargs curl --silent -o /tmp/weather_map_satelite.jpg\

Weather Radar LA

curl --silent "http://www.weather.com/weather/map/ USCA0638
