Actual Precipitation:

Image below shows precipitation in the area. Green areas change/move like you'd expect with areas of rain/snow.

	Geocolor Good for viewing smoke, general cloud cover, snowpack Can use daytime or nighttime Faster loading/less detailed image here.
	Infrared with Lightning Good indicator for height of clouds Colder/higher cloud tops are blue Can use daytime or nighttime Lightning "flashes" indicate include in-cloud, cloud to cloud, or cloud to ground flashes.
	Fire Temperature Good indicator for wildfire location and movement Brighter reds indicate hotter fires
	Day Cloud Phase Distinction Helps determine if clouds include ice or not Clouds transitioning from white shades to green and yellow shades indicate stronger showers
	Water Vapor Imagery Used for tracking winds and moisture in the middle troposphere, as low as around 18,000 feet, or 500mb. Surface features are usually not apparent in this band.
