Display of the wrong number of columns of wttr.in weather report using bash.rc

I am using Ubuntu 16.04 with the Unity Desktop.
My bash.rc includes some lines at the end of it as follows:
...
cowsay -f $(ls /usr/share/cowsay/cows/ | shuf -n1) $(fortune -ace /usr/share/games/fortunes)
echo -ne "${LIGHTGREEN}" "Hello, $USER. today is, "; date
echo -e "${LIGHTGREEN}"; cal -3;
curl wttr.in/Valladolid

I do not know why this happens. Please, some help would be appreciated. Thanks.
