Radar Screenshots and GOES-19 Satellite in Snowball
Pull a live radar screenshot for any US location or browse GOES-19 satellite imagery by region, product, and view type — all from Discord.
Snowball gives you two ways to see what the atmosphere is doing right now: a radar screenshot pinned to the nearest WSR-88D station for your exact location, and GOES-19 satellite imagery covering the US, surrounding oceans, and beyond. Both commands work entirely inside Discord — no browser required.
The radar command finds the nearest WSR-88D Doppler radar station to your location and returns a screenshot of the current scan. A View Interactive Radar button lets you open the live, interactive radar at radar.xtremewx.com for real-time animation and panning.
Radar coverage is limited to the United States. Snowball also requires a WSR-88D station within 150 miles of your location — areas farther from a radar site will not return an image.
The satellite command fetches the latest GOES-19 imagery from NOAA’s NESDIS CDN and posts it directly in Discord. You can choose a product (what the imagery highlights) and a region (which geographic area to show). Snowball can also infer the right region automatically from a location name or state.
Snowball supports a wide range of GOES-19 products:
GeoColor (default)
True-color visible imagery during the day and multi-spectral infrared at night. The best all-purpose view for seeing cloud cover, storm systems, and overall weather patterns.
GLM Flash Extent Density (Lightning)
Lightning flash extent density overlaid on GeoColor. Shows where lightning is occurring across the field of view.
AirMass RGB
A multi-channel composite that highlights different air masses using infrared and water vapor bands. Useful for tracking fronts and upper-level dynamics.
Sandwich RGB
Infrared Band 13 blended with visible Band 3 for enhanced contrast on cloud tops and storm systems.
Derived Motion Winds
Wind vectors calculated from the movement of clouds and water vapor features. Available for CONUS and Full Disk views.
Day Night Cloud Micro Combo
Highlights cloud-top phase during the day and detects low clouds and fog at night.
Fire Temperature RGB
Designed to identify active fire hot spots and estimate fire radiative power.
Dust RGB
Detects and highlights tropospheric dust plumes.
Individual spectral bands (Bands 1–16)
All 16 ABI spectral bands are available, from visible blue (Band 1) through CO2 longwave infrared (Band 16). Each band highlights different atmospheric and surface properties.
You can specify a region directly, or let Snowball infer one from a location name or state abbreviation. Available regions include:
CONUS — Full continental United States
Full Disk — The entire Earth disk as seen by GOES-19
Meso M1 / Meso M2 — The two live mesoscale sectors (updated every minute)
Regional sectors — Northern Rockies, Upper Mississippi Valley, Great Lakes, Northeast, Southern Rockies, Southern Plains, Southern Mississippi Valley, Southeast, U.S. East Coast, Canada, Northern Atlantic Ocean, Caribbean, Gulf of America, Puerto Rico, Tropical Atlantic Ocean, Eastern Pacific Ocean, Mexico, Central America, and both northern and southern South America
