Back-to-back powerful Pacific storm systems to impact the Pacific Northwest and northern California through the end of this week with heavy rain, flooding, strong winds, and higher elevation mountain snow. A strong, long-duration atmospheric river will accompany the Pacific storms, bringing excessive rainfall and flash flooding to southwest Oregon and northwest California through the week. Read More >

Overview

A powerful mid latitude cyclone made landfall over the western United States and eventually made its way into the central and northern Plains over the Thanksgiving Holiday weekend. Freezing drizzle and some light snow began to fall across parts of western and central North Dakota on Thanksgiving evening, continuing through much of the day on Friday. As the brunt of the storm continued to slowly push north and east, snowfall rates increased across the south on Friday evening, with heavy snow developing across most of the southern half of the state late Friday night and through much of the day on Saturday. Further north and west, the atmosphere was slower to saturate and a prolonged period of light freezing rain and freezing drizzle continued through much of the event. When all was said and done, much of the south saw 6 to 15 inches of snowfall accumulation while portions of the west and north saw ice accumulations of over a quarter inch.
