This link takes you to weather maps and forecasts prepared by NASA’s Global Modelling and Assimilation Office (GMAO). The most important map display involves atmospheric aerosols (e.g., African Dust). It can be found under “Chem Maps” and shows Atmospheric Optical Thickness. After clicking on the map to obtain the larger image, you can animate the maps by clicking the “Animate” button at the bottom of the page.

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.
Plymouth State University Weather Center
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.
Pennsylvania State University E-Wall
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
COD’s 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.
College of DuPage
Created by students at OU, the site features lots of real-time weather data.
