Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 154 AM EST Thu Nov 16 2017 Valid 12Z Thu Nov 16 2017 - 12Z Sat Nov 18 2017 ...High wind, heavy rain and mountain snows to persist across the Pacific Northwest and California... A multitude of hazards will affect the Western U.S. on Thursday as a storm system comes ashore. Persistent onshore flow behind a cold front will stream pacific moisture into the Sierras and Cascades, reaching the Great Basin and northern Rockies later in the day. Heavy rainfall is expected from Washington southward to central California where the brunt of the heavy rainfall is expected in the lower elevations of the central Sierras. High winds and heavy snowfall are expected from the Cascades and Sierras to parts of the central and northern Rockies. Winter storm watches, warnings, and winter weather advisories are in effect across the region. Record high minimum temperatures will be possible across parts of the southwest, Great Basin, and central Rockies on Thursday and record high maximum temperatures will be possible across parts of the southern Plains on Friday. Light precipitation will spread east across the Rockies into the adjacent High Plains as a weak cold front passes through the central U.S. The cooler, post-frontal airmass will linger over the central CONUS as high pressure returns.
