The Aviation Digital Data Service provides a wealth of useful information. I start with the TAFs on this page. In the lower part of the page, below the map, you can input your destinations and obtain the current METAR (if you check the box) and the TAF. You can also obtain both graphical and textual compilations of area TAFs around the particular region. Note also that if you pull up the ADDS METAR page here, you can pull a set of recent METARs, up to 36 hours prior if you wish to study the trends.
