Site contains much weather information, including “departure from average temperature” maps.
The Next Generation Weather Lab features many great weather analysis tools. In addition to the usual suite of satellite and radar imagery, surface and upper air weather maps and NWP output, the site also has pressure change maps, cross sectional analyses and isentropic charts.

This site features an array of surface weather maps for the U.S., North America and the globe. If you click on the Unified Surface Analysis (hyperlink near top of page), you’ll get a global view of surface highs, lows and fronts. Click on the map and you’ll zoom into that area and see plotted surface weather reports.

This is an easy-to-navigate and interactive site with an incredible array of data. You can “make your own” of almost anything; and you can retrieve a large amount of “archived data.” Most of the maps you can create allow you to define location, zoom, change font size, and other attributes. The national map plot with station model data is a bit crowded, but regional maps are close to “perfect”. There’s so much stuff here that I’m still learning what is available.

This site has its information arranged as one huge “wall.” But, if you look to “nooks and crannies” and capitalize on the left margin menu, you’ll find radar and satellite data and the best 24-hour temperature change map on the web. You can use this map to track how cold and warm fronts are moving across the U.S. This site requires a lot of self-learning to ensure you know what is posted.
