Best Hiking Window

Friday morning offers the most viable window, when the high pressure crests midday and winds drop off. Plan an early morning start to take full advantage of the brief calm and clearing before the next storm system's clouds and snow return Friday afternoon. Avoid Thursday entirely due to extreme wind chills and the active wind chill advisory. Saturday and Sunday look increasingly poor with heavy snow showers forecast.
