air from the previous system, bringing heavy snow to parts of western Washington. Eleven inches of snow fell at Olympia airport and almost seven inches fell at Seattle-Tacoma International Airport on January 18, respectively becoming the third- and sixth-highest totals on record. As much as two feet of snow fell in the Oregon Coastal Range, and additional heavy snow totalling near-record-to-record levels was reported to the east across the Blue Mountains in eastern Oregon and the Sawtooth and Bitterroot Ranges into the northern Rocky Mountains. As the system progressed eastward from 12:00 UTC January 18 – 12:00 UTC January 19, the low-level cold air over western Washington was backed up by continuing precipitation and surface flow from the north. This paved the way for the eventual freezing rain event that affected the region, including its first-ever ice storm warning. Ice accumulations ranging from one-half to three-quarters of an inch were reported in the vicinity of the Seattle-Tacoma metropolitan area, with totals of an inch or higher being reported in areas south and east. Heavy snow falling along the Cascade Range expanded southward into northern California and along the Rockies into the Tetons and northern Wasatch Mountains. An arctic surface high settled south through the northern Plains with the front amassing against the eastern slopes of the northern Rockies. High winds with gusts of up to 100 mph were reported across and east of the mountains. The systems affected much of the northwestern U.S. with rain, snow, and ice, with snow blanketing areas from the Pacific Northwest to the northern Plains. By 12:00 UTC January 20, snowfall ranging between 2 and 5 feet had been reported across the Cascade Range with the heaviest amounts focused near the Mount Hood area. Widespread totals of 1 to 3 feet of snow were recorded in the northern Rockies, with the highest totals falling along the Sawtooth Range, where 3-to-6-foot totals were frequent, with reports ranging as high as 70 inches. Widespread rain of 3-to-6 inches with local totals as high as 9 inches occurred along the coast of northern California, and totals as high as 15 inches were reported along the coast of Oregon. Ice accumulations of one-quarter to one inch were reported across the Columbia River Gorge east of Portland with similar totals across the Seattle-Tacoma metropolitan area.

Midwest, with winds across parts of the Central Plains through the Upper Mississippi Valley reaching 50–60 miles per hour (80–97 km/h). Simultaneously, light to moderate snow developed across parts of the Northeastern U.S., with snowfall rates decreasing into the night of February 29. However, snow redeveloped by the following morning, with snowfall finally coming to an end shortly thereafter. The storm's most-significant impacts were observed across the Upper Midwest, with numerous power outages occurring in tandem with the closure of roads, schools, and businesses. Interstates 29 and 90 were temporarily closed due to unsafe weather conditions, and accidents on state highways were reported to number in the hundreds. The only fatality reported to have occurred due to the storm occurred in Minnesota, with the death being attributed to exposure to extremely cold temperatures. Despite damage reports from the storm totaling $ 741 thousand, the storm alleviated some of the pre-existing drought conditions in the north-central U.S. A late-season storm brought precipitation to an area extending from North Carolina to Maine on April 22, with moderate to heavy rain falling along the coast and a secondary area of precipitation being observed farther inland. The highest precipitation totals were observed in northeastern Pennsylvania and central New York. Enough cold air was brought into place by the storm so as to allow for snow to fall in the higher elevations of the central Appalachians on April 23. The storm took a northwestward turn as it weakened, permeating a substantive distance into Quebec by 00:00 UTC April 24. Much of the initially impacted area between North Carolina and Maine observed rainfall totals in excess of one inch (2.5 cm), with totals locally nearing five inches (12.7 cm) across parts of New England. Parts of the central Appalachians received over four inches (10.2 cm) of snow, with portions of western New York and central Pennsylvania reporting over 12 inches (30 cm) of snow. During its lifetime, the storm complicated travel along the Interstate-95 corridor, and travel was made especially hazardous along coastal New England. Thousands of power outages were reported, but no direct casualties occurred. The storm caused a reported $ 206 thousand in damages, largely due to snow and wind.

the Pacific Northwest, cold air associated with the system went on to pervade the Rocky Mountains and central Great Basin, with heavy snow later returning to the coastal mountains in the Cascadia region. Snow totals in the Seattle and Olympia areas as well as the Blue Mountains and parts of the Rockies reached near-record-breaking levels. Snow in western Washington transitioned into freezing rain, resulting in a historic ice storm event, with heavy snows expanding into Northern California and the Rockies, including the Tetons and the northern Wasatch Range. Cold air and snow spread into the Northern Plains, and high winds affected areas in and just east of the Rockies. Widespread rain fell along the coasts of Northern California and Oregon. The storm left three dead and four injured in its wake due to a combination of flooding and fallen trees. This storm was to be followed by another storm in early February. The major winter storm, originating from a disturbance in the subtropical jet stream, brought snow to parts of Kansas and south-central Nebraska, with cold air drawn in from the north. Areas to the east in the Middle Mississippi Valley were warmer and saw rain instead of snow. The highest snowfall totals were reported by the National Weather Service to have occurred from an area extending south from Laramie, Wyoming to the Colorado foothills as well as an area east of Denver. The foothills saw a few reports of snow totals in excess of 36 inches (91 cm), with Black Hawk receiving 48 inches (120 cm) of accumulation. Lesser but still significant snowfall fell over parts of Nebraska from North Platte to near Omaha. Wind gusts of over 40 miles per hour (64 km/h) were observed across eastern Colorado and Nebraska. Approximately 600 flights were canceled in Denver, Colorado as a result of the storm, and due to heavy snow and strong winds, Interstate 70 was closed from Denver to the Kansas border. The storm resulted in power outages affecting 15,000 people and caused an estimated $ 693 thousand in damage. However, this was largely due to flooding in the Southern Plains and Lower Mississippi Valley rather than the wintry impacts to the north.
255:, with CPC deputy director Mike Halpert saying, "The erratic Arctic Oscillation can generate strong shifts in the climate patterns that could overwhelm or amplify La NiΓ±a's typical impacts." The outlook was broken up into ten regions. The outlook anticipated above-normal wildfire conditions across the entire southern part of the United States, cooler and wetter-than-average conditions in the Pacific Northwest and western Montana, likewise for northern California, and drier-than-average conditions for southern California. Colder and wetter-than-average conditions were favored in the Northern Plains, but the converse was expected to occur in the Southern Plains and Gulf Coast states, worsening pre-existing drought conditions. In Florida and the southern Atlantic states, equal chances existed for below, near, and above-average temperatures, with below-average precipitation favored for the region and above-normal wildfire conditions. Equal chances for below, near, and above-average temperatures existed in the Ohio and Tennessee Valleys, with wetter-than-average conditions favored, resulting in an enhanced potential for storms and flooding. Equal chances for below, near, and above-average precipitation and temperatures existed in the Northeast and Mid-Atlantic states. The outlook noted that winter weather in this region often driven by the Arctic Oscillation rather than La NiΓ±a, and as such, if enough cold air and moisture were to coalesce, areas north of the Ohio Valley and into the Northeastern U.S. could expect above-average snowfall. Colder and wetter-than-average conditions were favored in the Great Lakes region, and above-average temperatures with above-average precipitation were favored in the western islands of Hawaii, resulting in the potential for elimination of drought, particularly in Kauai and Oahu. The outlook ended by noting chances favoring below-average temperatures in the southern half of Alaska and the panhandle with below-average levels of precipitation favored in the eastern interior region of the state. 463:(12:00 UTC) position over the southern Aleutian Islands to near the Gulf of Anadyr by 9:00 p.m. (06:00 UTC November 9), by which time its pressure had decreased to 945 millibars (hPa; 27.91 inHg). The system then went on the cross the Chukotsk Peninsula at 9:00 a.m. (18:00 UTC) on November 9 with a pressure of 956 millibars (hPa; 28.23 inHg), weakening to a 958-millibar (hPa; 28.29-inHg) low over the Chukchi Sea by 9:00 p.m. (06:00 UTC November 10). It then translated in a northwestward direction, ultimately weakening to 975 millibars (hPa; 28.80 inHg) by 3:00 p.m. on November 10 (00:00 UTC November 11), roughly 150 miles (240 km) north of Wrangel Island. During the storm, numerous areas saw winds, sometimes of hurricane-force, combine with snow to create blizzard conditions. This occurred in the village of Wales, which saw winds gust as high as 77 knots (89 mph). The National Weather Service office in Nome recorded 6.4 inches (160 mm) of snows during the storm. Apart from the mainland, additional impacts were observed on the islands of 483:
much for the pumps, resulting in the release of 165,000 gallons of wastewater into a small boat harbor. According to the City of Nome, approximately $ 500,000 in damage was caused to the Cape Nome Jetty, with an additional $ 80,000 caused by wave action and erosion. About $ 24 million in damage was caused to parts of the Nome-Council Road. A vessel bound for Nome carrying the city's last scheduled delivery of fuel before winter was delayed, and sea ice quickly formed in the week after the storm, preventing the delivery from being shipped until January 2012. Large pieces of ice were brought inland by high waters in Saint Michael and Koyuk, and in the former, heavy equipment was required to remove them from a road. Winds associated with the storm brought about numerous power and phone line outages in Point Hope, and about 550 of the town's 674 residents were evacuated to a local school. A 26-year-old was presumed dead after he drove his vehicle into large waves near the village of
517:. The storm then resumed its northward trek into the Ohio Valley. Due to the quickening of the frontal rainfall across the Appalachian Mountains and the Mid-Atlantic region, areas in the eastern United States received a reduced amount of accumulated precipitation. By the time the storm had passed, peak rainfall totals had been recorded in eastern Tennessee and the southern Appalachian region, where totals of over 5 inches (130 mm) were noted. As the occluded cyclone moved northward, cold air from the northwest caused rain to transition to snow across Lower Michigan and northern Indiana on November 29 during the afternoon. A band of organization near the rear of the cyclone brought, for a limited time, heavy snow to aforementioned parts of Indiana in addition to central Lower Michigan. In excess of 6 inches (150 mm) of snow were reported in these areas, with maximum totals of near 10 inches (250 mm) in the vicinity of Peru, Indiana and Lansing, Michigan. 542:
Winter Storm and Blizzard Warnings for parts of western and central Kansas, central and northern New Mexico, southeastern Colorado, and the Oklahoma and Texas panhandles. Clayton, New Mexico, saw 17.7 inches (450 mm) fall on December 19 and 20, and Lamar, Colorado measured 19.0 inches (480 mm) of snow on December 20, a new December record for one-day snowfall. Some areas affected by the system saw snow drifts in excess of 2 to 4 feet (0.61 to 1.22 m). As the system trekked to the northeast, the temperatures it encountered were more moderate, and rain became the primary mode of precipitation in Kansas through the Midwest and Mississippi Valley. On the eastern edge of the heavy snow, a rain/snow/sleet mixture created slick conditions of roads in parts of central and south-central Kansas. The system also brought 1.5 to 2.5 inches (38 to 64 mm) of rainfall to parts of south-central and southeastern Kansas.

Many residents of affected areas were discouraged from traveling at all, with speed limits reduced between New Jersey and Pennsylvania. Across parts of the area affected by the storm, local government officials canceled or pushed back Halloween activities for safety-related purposes, and state governors declared states of emergency in Connecticut, Massachusetts, New Jersey, and parts of New York. Thirty-two shelters were opened in Connecticut, and the state's governor asked that volunteer fire departments open their doors to people to provide warmth and showers. NOAA publication

In late November, another storm affected the United States, bringing snow to the central Mississippi Valley. The storm ultimately dropped a few inches of snow across parts of Arkansas and Missouri in the central Mississippi River Valley before advancing into the Ohio Valley where it brought rain and snow to

Many trees were downed because they had not yet lost their leaves, resulting in downed power lines and more than 3,000,000 residents losing power, some of whom remained without power for over a week following the storm. The storm ultimately resulted in one direct fatality and $ 18.8 million in damage. Slightly over a week later,
404: 400:. The low ultimately attained its absolute lowest pressure of 976 hPa (mbar; 28.82 inHg) at 15:00 UTC on October 30 east of the southern tip of Nova Scotia. An area spanning the distance between northeastern Pennsylvania and southern Maine saw snowfall totals of greater than 12 inches (30 cm), with parts of both New Hampshire and Massachusetts seeing totals in excess of 30 inches (76 cm). 581:. During the 12:00 UTC January 15 – 12:00 UTC January 16 period, the upper-level low and trough persisted in its inland movement, with the front of the cold air advancing southeastward through the Great Basin and Rockies. Precipitation across the Pacific Northwest region subsided early on January 16, although some light precipitation continued through the northern Rocky Mountains. 396:
