The MIMIC microwave satellite loops of intense tropical cyclones are always a show-stopper. What puts this page over the top for me, though, is the satellite analyses of entire tropical basins for wind shear and Saharan air layers. UW-Madison tropical cyclone satellite page: A solid page for analysis of ongoing tropical cyclones.There's usually at least a handful of impressive rain or snow totals in every decent storm due to the efforts of these volunteers. CoCoRaHS: A national network of trained volunteers taking precipitation data that supplement official NWS observations.Utqiagvik sea ice webcam: Speaking of extreme, if you want to see what life is like in America's northernmost town, Utqiagvik (formerly known as Barrow), or if you want to see what limited twilight is like in the dead of winter, this is your cam.Mount Washington Observatory: The New Hampshire mountaintop weather observatory has live webcams, current conditions and a compelling blog in one of the most extreme environments on Earth.NOAA/NOHRSC national snow analyses: You not only can pull up today's snow cover maps, but also for any day since 2003.CIRA/RAMMB tropical cyclone page: You can dive deep into analysis of active tropical cyclones worldwide, including microwave imagery, satellite-derived wind analyses and ocean heat content.

It even allows you to pull up archived imagery. In addition to conventional visible, infrared and water vapor imagery, you can also view GOES global lightning mapper data. You can choose between GOES-East, GOES-West, Himawari-8 (west Pacific), even JPSS for views of polar regions. CIRA/RAMMB satellite slider: A spectacular site for satellite imagery.
