The next system to arrive in southern Oregon and northern California will bring low elevation snow all the way down to the valley floors. The wind pattern with this system will favor snow accumulations on the northwest aspects of mountains, including along the Umpqua Divide near Canyon Mountain and the southern Rogue Valley near Ashland, where snow amounts will be a little higher than in other places with similar elevations. Snow could start as early as 4 AM, but the peak snowfall rates will occur around 10 am, then should lessen in the late afternoon into the early evening as snow levels drop to the valley floors. Showers may linger through Monday morning and could produce additional light accumulations.
A second system will arrive Tuesday and remain in the area well into Wednesday. This will be a more potent system, but with more southerly flow ahead of the front. This pattern favors moderate to heavy snow in the Mt. Shasta area, with snow levels in western and southern Siskiyou County likely dropping to around 1500 feet. The duration of this event is key, as it could persist for up to two days, leading to significant accumulations of wet, heavy snow.
