Animate forecast ceiling, surface visibility, and combined VFR, MVFR, IFR, or LIFR conditions for the United States and every state.

Open United States Forecast

One forecast, three practical views

This aviation ceiling and visibility forecast helps pilots, skydiving operators, and weather-sensitive flight teams follow changing conditions hour by hour. Compare forecast cloud ceilings, forecast visibility, or the combined flight rule category on national and state maps. Smooth color-filled contours make broader weather trends easy to recognize while unshaded locations remain unclassified.

Ceiling Forecast

Track the lowest forecast broken cloud layer, using the 5/8 (62.5%) sky-cover threshold, and see where ceilings may cross key aviation categories.

Visibility Forecast

Follow forecast surface visibility and identify areas approaching MVFR, IFR, or LIFR visibility thresholds.

Flight Rule Forecast

View the more restrictive result of ceiling and visibility, with VFR drawn first and progressively lower categories layered above it.

Animated aviation weather by hour
