MMM image archive This is probably the best "one-stop shop" for looking at archived images. It includes radar composites, satellite images, soundings, surface and upper-air maps, and much more. SPC severe events archive This is another good place to get started with surface and upper air analyses, soundings, etc. It also does have a few archived images for quick looks. MesoWest Outstanding real-time and archived surface observations from both standard sources and the various mesonets around the country. Contains a wealth of archived observations that can be easily plotted via their web interface. Plymouth State Allows you to create your own surface charts. Wyoming Comprehensive sounding archive, goes back to the s.

Past radar images tool includes several unique features that allow users to select data from —present for individual or multiple stations at varying altitudes. Radar can see things in the atmosphere other than precipitation.

This data is gathered from over a hundred radar towers located across the US. This is the highest resolution radar data available which enables you to see features such as sea breeze or outflow boundaries that standard resolution radar entirely misses. There is a notable constraint to radar data though. Because the earth is round and the radar beam is flat, the farther away from the radar tower the beam energy travels, the farther removed from the ground becomes. To see this in action, imagine a circle earth with a straight line emanating from some point on the circle if you continue this line out into space, it will gradually get farther and farther from the circle. Because of this phenomenon, the radar beam will only see precipitation falling through the mid levels of the atmosphere.

The tool includes several unique features that allow users to select data from —present for individual or multiple stations at varying altitudes. The map tool uses the Reflectivity Mosaics products and web services provided by the Iowa Environmental Mesonet. Reflectivity is available from to near-real time in five-minute increments. The raw data are not available for download and are only accessible as images on this map or from the Iowa Environmental Mesonet. The typical range of most radar products is km from the radar site. However, mountains can block the lower sweeps of the radar beam.

Use radar data with caution especially if your area of interest is far from the nearest radar location!

If satellite data shows clear skies but you see signatures on radar data, it could be anything from smoke from a fire to a flock of birds taking flight to dust particles collecting along a boundary. However, mountains can block the lower sweeps of the radar beam. Subscribe Now. Base reflectivity dBZ. SPC mesoanalysis archive Archive of SPC's objective analysis--only has the full country images in the archive, rather than the individual subregions. This signature indicates the presence of a strongly rotating mesocyclone- often an immediate precursor to tornado development.

SPC severe events archive This is another good place to get started with surface and upper air analyses, soundings, etc. Use radar data with caution especially if your area of interest is far from the nearest radar location! CSU On our site with real-time weather data, we also maintain an archive of model forecast images going back several weeks. This is especially cool in the summer when sea breeze fronts show up on radar.

Things to watch for: Bow echoes- when a storm looks like a bow as in bow-and-arrow , it signals a strong push of cold outflow near the surface. Soundings Wyoming Comprehensive sounding archive, goes back to the s. The Interactive Radar Map Tool shows map layers at the maximum distance km , as well as maps derived from geospatial models that provide views of areas blocked by mountains. Plymouth State Plot your own upper-air maps. If you require access for more users, you can create additional subscriptions. A few tips on reflectivity data:. The Weather Chaser provides access to the highest quality weather data available for Australia. You can make some simple plots right from the web page, or download the data GRIB format.
