There is the National weather web-site
http://forecast.weather.gov
Once on the site you just type in the zip code for your area. On the upper right hand side of the page you'll see a "past 3 days" tab, click on it.
Good Luck

I use weather underground.
http://www.wunderground.com/wundermap/?lat=33.46122742&lon=-81.97173309&zoom=8&pin=Augusta%2c%20GA

Click on one of the temperature circles in a city near you.

You can click on a weather station id int the upper left of that pop-up screen.
The next screen will have tabs for daily, weekly, monthly, yearly history of rain, pressure, wind etc.

Wunderground, perfect! They keep all the data on a calendar for easy reference. Thanks!

I will ONLY use weatherunderground; I've been using it for a number of years now. It provides all the weather information I need for monitoring and making daily decisions.

Wunderground.com is my favorite choice.
