Hi Kris,
I would consider running the web site off a page seperate to your business. In time as you get more confortmable with the technology you may be able display weather information on your business page(s).
Weather Display may apear complex however with some time and patience you can create professional looking webs sites (not claiming mine is at all). Additionally, there are a number of templates to get you started. Try the following:
http://www.carterlake.org/" onclick="window.open(this.href);return false; or
http://www.tnetweather.com/" onclick="window.open(this.href);return false;
The weather display software can be configure to upload the data directly to your hosting provider however I prefer a little more control by using and FTP program.
Cheers
Damian
