Introduction and event overview

A series of at least three Pacific storms moved into Washington State and Oregon from Thursday February 11 through Sunday February 14, 2021. The storms dumped widespread heavy snow, sleet, and freezing rain through most of the western half of both states. Areas affected included the Puget Sound region of Washington State, the Portland, Oregon metro area including Vancouver, Washington on the north side of the Columbia River, and even the immediate coastal regions.

The reference to at least three storms is to account for weaker waves of low pressure that were embedded in the atmospheric flow between the stronger storms and produced light scattered precipitation between the periods of heavier snow and ice. The storms interacted with cold air from a strong Arctic high pressure system covering Canada including the Yukon and Northwest Territories and extending south through British Columbia and Alberta and then into then into the Plains of the United States. In fact the cold air mass extended all the way down to the Gulf Coast. The Arctic high pressure system remained in place through most of the stormy period so that cold air could continue to bleed south and west into Washington and Oregon.

The initial shot of precipitation in the form of snow started around 8 AM PST on February 11, 2021 in Olympia, Washington and Tacoma, Washington, then spread north during the late morning and early afternoon to Seattle on Feb 11, 2021. Precipitation started as mostly rain in the Portland, Oregon area around 6 AM, then gradually mixed with sleet and snow late morning and early afternoon, then changed to all or mostly snow. For those interested in the details of the reported weather conditions, such as precipitation type and winds, the surface observations from the Seattle-Tacoma International Airport (SEA) and the Portland International Airport (PDX) are listed after the "References" section at the end of this article.

Snow and ice totals

The Seattle/Tacoma National Weather Service Forecast Office reported that a total of 9 inches fell at the office itself and a hefty 12.4 inches at the Seattle-Tacoma International Airport. Important to note was that the boundary layer winds maintained a strong easterly component, initially from the northeast early in the event, then from the east for the rest of the event. National Weather Service forecasters emphasized in their discussions that the warming and drying effect of the winds off the Cascade Mountains to the east would erode the cold air that was already in place and limit snowfall amounts. The erosion of snow would be stronger east side of the Seattle metro area. If it had not been for this downslope wind action snow totals may have been even more impressive. The persistent east winds were due to the pressure gradient between the approaching storms to the west and high pressure to the east.

The National Weather Service Forecast Office at Portland reported that 9.6 inches of snow and sleet fell at the Portland International Airport but the more eye-catching reports were the ice accumulations from the freezing rain. Accumulations ranged from 0.5 to 1.5 inches thick across Portland and south into the Central Willamette Valley. Ice accumulations were a little less in the 0.25 to 0.5 inch range to the north in Vancouver as more precipitation fell as snow compared to areas farther south. Even Astoria very near the Pacific Coast reported 0.2 inches of ice accumulation. The same pressure gradient mentioned earlier helped to draw cold air west through the Columbia River Gorge and lock the cold air in place at the surface for an extended period of time. Occasional intrusions of warm air above the surface resulted in precipitation switching back and forth between snow and freezing rain or sleet. Once rain or mixed precipitation changed over to snow, the snow dominated the first half of the event, then freezing rain dominated the second half. The cold air was so persistent that freezing rain continued to fall at the Portland International Airport through Sunday evening February 14 and into the predawn of the 15th.

Winter storm warnings and advisories

The following maps show the warnings and advisories issued by the National Weather Service during the event. The first map covers Northwest Washington State. The second map covers Southwest Washington State. The third map is a United States view to see the full extent of what was happening across the country. Quite a busy map showing snow, ice and low wind chills occurring or anticipated over most of the country. Winter Storm Warnings are coded pink, Ice Storm Warnings are in violet (or very dark pink), and the weaker violet or purple indicates advisories for lesser amounts of snow and ice.

Atmospheric support

As stated earlier, a strong arctic high pressure system was supplying cold air from the north and the east. What was not prominent was a strong upper-level trough covering the Pacific Northwest of the United States, southern British Columbia, and the adjacent Pacific Ocean. A prominent trough over the area is favorable for allowing cold air to move into the region. Given enough time, cold air was able work to its way south and west especially through the river valleys and mountain passes such as the Fraser River Valley, the Columbia River Valley, and other pathways. The Winter Weather Processes page on this website examines cold air outbreaks in the Pacific Northwest in greater detail.

The North American surface map at 4 AM PST February 11, 2021 shows the extent of the high pressure system. The first upper air map at 500 mb valid for the same time shows a polar vortex centered south to southwest of Hudson Bay. Strong flow extends northwest to southeast across Washington State and Oregon but a well defined upper-level trough is not in place. Compare this somewhat zonal flow to the second 500 mb map. This second 500 mb map is from the beginning of a period of successive snowstorms that affected Seattle from February 3 to 12, 2019. A strong trough with a closed circulation was sitting just offshore of Washington. Through time this trough moved east and weakened but was then replaced with another similar trough five days later to keep the pattern in place to support more cold air for snow.

Storm evolution

A series of weather maps shows the progression of the storms moving into the Pacific Northwest. The first set of maps is a regional surface analysis for Washington and Oregon to show the movement of the low pressure systems that produced the wintry precipitation. The second set of maps shows the upper level structure of the storms at 500 mb. The third set of maps is a radar mosaic showing the periods of greater precipitation coverage and intensity.
