Read across a row to see how it changes hour to hour. The colored band is the flight category (VFR / MVFR / IFR / LIFR). The wind arrow points the way the wind is blowing. Sky shows the ceiling, or the lowest layer when there's no ceiling, with the cloud cover % below. Shaded columns are civil twilight (mauve) and FAA night (blue). Amber marks wind over 15 kt or a ceiling under 2,000 ft. Wind, temperature, precip and cloud % come from the NWS gridded forecast; ceilings come from AWC's GFA cloud forecast, which only reaches 18 hours out, so later hours show N/A.
