# Snazzy Weather server script v0.2
# As of writing, the script only runs early in the morning
# to get the morning version of the NOAA weather data,
# since the afternoon/evening report does not include
# morning data. I'll eventually make a version that
# keeps things more up to date. Probably.
# I have this script set to run via crontab -e
# Example to put in cron job file on your server:
# cd /home/user; ./getweather.sh > finalweather.txt
# Snazzy weather then downloads http://old.jojo2k.com/finalweather.txt
# for its weather data.

# Go here for more info about the NOAA/NWS weather API and find your own location
