US Radar MapGo to the link and bookmark it.. This is the CONUS map (Contential US) and from here you can link to sectional maps and even other types of maps.
I visit the CONUS radar map every day and if there is anything "interesting" the sectional map (Currently S.E. Loop)
Now do not do this once, Do it every day and with time you will see how the patterns on the map affecdt what you plan for the day or at least the next couple days.. I'm getting to where I can often predict storms. especially big storms, 2 or 3 days out.
