Each mountain shows five days from left to right. Only 7am–7pm is plotted; shaded gaps skip the nights. Scales match across mountains. Bars show hourly liquid-equivalent precipitation (including snow); purple means snowfall is also forecast, not snow depth. Hover, tap, or focus a time for exact readings. On phones, swipe a chart sideways.
Temperature °F · Wind / gusts mph · Precipitation chance and amount for the preceding hour. Amount is liquid equivalent, including snow; snowfall depth appears separately when forecast. Red = precipitation chance >50% or sustained wind >15 mph. Yellow = precipitation chance >25%, cloud >50%, or sustained wind >7 mph. Green = the rest. Red takes priority; gusts do not affect shading. Sort uses all hourly readings from 7am–7pm, including hours between the displayed readings. On phones, swipe sideways to compare times.
