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.

National Sky Awareness Week
Pennsylvania State University E-Wall
This site has its weather 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 also 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.

NOAA NCEP (CPC) – High and low temperature maps and departures
This page shows high and low temperatures (observed and departure from average) across the U.S. Unfortunately, the images are 36 to 48 hours old.
NCEP/CDC Temperature Maps
Aeris Weather
Site contains much weather information, including “departure from average temperature” maps. You’ll just have to do some clicking of the many links provided.
NOAA (NCEP – NOAA Centers for Environmental Prediction) – analyzed surface weather maps
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.
