Weather Timeline - Nov 16th through 20th

Another round of beneficial rain/low impact weather is expected through early Monday. Rain will develop first in NE California and east of the Cascades tonight, then also along the coast, eventually pushing inland across all of the area Sunday into Monday. Snow levels will remain high through the heaviest precipitation, around 7000-8000 ft, then lower to around 5000 ft early Monday. Light snow is expected in the Cascades with limited winter impacts. Gusty winds return Sunday, mainly in the Shasta Valley and over the East Side, but remain below advisory criteria. Gusts of 20-30 mph will be common, but up to 40 mph in the Shasta Valley could make for challenging driving conditions for high profile vehicles.

A cold front will bring chances of rain showers across the area from this afternoon through Monday night. The highest amounts are expected over Curry County, western Siskiyou County, and the Mount Shasta region. Snow levels of 5000-6000 feet will limit snowfall to higher terrain. Gusty southerly winds may be present in the Shasta Valley and over east side terrain. Activity eases on Tuesday, but lingering cold air behind the front will bring lower overnight temperatures Tuesday night into early Wednesday morning. Frost/freeze conditions may be present in the Rogue, Applegate, and Illinois valleys, and frost conditions may be present in the Umpqua Valley. East side areas and Siskiyou County will also see lower overnight temperatures. Another weak system may bring more showers to west side areas Wednesday afternoon into Thursday, but hazardous conditions are not currently expected.
