Stu's Weather Thumbrules

Stu's Weather Thumbrules

These thumbrules are intended for the Flagstaff, Arizona area.
Mondays and Thursdays
Weather forecasts shift on Mondays and Thursdays. Especially in the winter. Particularly in the afternoons
Southern Storms
Low pressure systems approaching from the south leave much of their moisture on the Mogollon Rim. Thus, they produce less than forecasted precipitation.
Wind and Snow
If it is windy, snow will not start to fall. If it is snowing, the wind will not increase by much. If the wind significantly drops, the snow can begin. Drifting of snow may occur after it is on the ground.
Lingering Snow Cover
Although recent history (prior to 2007) has been to the contrary, accumulating snows can remain on the ground for weeks. In the past, the lore has been that it snows and the snow disappears after a few days.
