Changes to the web-site! I have moved most of the routine graphics that had been at the bottom of each forecast onto a set of tabs on the homepage. Additionally, many of these tabs now update automatically with the latest graphic, rather than a manual process.

All the information (and more!) you have come to expect is still here. Here are permanent bookmarks for animations, the short-range graphics (what had been attached to each forecast) and the medium-range graphics.

The daily forecasts will now be much lower bandwidth and have many fewer graphics. Those graphics will be targeted to specific weather situations of interest for that particular forecast. Let me know what you think of the changes!!
