1st-7th…A strong cold frontal boundary extended from the southern Plains to the central Great Lakes on Thursday, while an arctic air mass continued to impact the West Coast. A cold front stretched from southern Texas to Lake Erie on Thursday, which pushed an active weather system across the central and eastern thirds of the country. Temperatures were 10 to 30 degrees below normal in the southern Plains, the lower Mississippi Valley and across the Appalachians as Ice storm warnings, winter storm warnings, and flood watches were issued. This cold front triggered freezing rain, sleet and snow showers across Texas, Oklahoma, Kansas, Missouri, Arkansas, Illinois and Indiana. Boise City, Okla., reported a midday total of 2.0 inches of snow, while Sherman, Texas, reported a midday total of 0.10 inches of ice accumulation.

The northern Plains and upper Midwest avoided precipitation on Thursday, although frigid, blustery conditions lingered over the two regions. Meanwhile, the western third of the country continued to experience very cold temperatures due to an arctic air mass over the area. Hard freezing warnings were issued across the Central Valley of California and into the desert Southwest, while winter storm warnings were issued along higher terrain. The coldest temperatures affected the Intermountain West and the Great Basin on Thursday, as Walden, CO, recorded a morning low of -32 degrees, and Laramie, Wyo., recorded a morning low of -29 degrees with a wind chill factor of -46 degrees.
A mixture of rain, snow, and freezing rain moved across the Eastern states on Friday as a strong cold front continued to make its way eastward throughout the day. The system pulled moisture in from the Gulf of Mexico, while also pulling cool air in from Canada. This allowed for rain and snow to develop from eastern Texas into the Northeast. 2.60 inches of sleet was reported at Macon, Arkansas, while 7.3 inches of snow was reported southwest of Mammoth Spring, Arkansas. The ice storm moved out of eastern Texas early Friday morning, with overnight sleet accumulation up to 3.5 inches at Little Elm, Texas. The northern side of this system brought heavy snow from Missouri through the Ohio River Valley. Snowfall reports ranged from 12 inches at Chester, Illinois to 9 inches at Frederickstown, Missouri. As this front moved through, it pushed cool air into the Southeast. Temperatures ranged from 15 to 25 degrees below normal across the region. Meanwhile, out West, below normal temperatures continued across the Western states as another strong low pressure system moved in from the Pacific Ocean. This system brought rain and snow showers to northern California and Oregon, with snowfall totals across the Cascades ranging from 3 to 5 inches. Snow levels continued to drop as this system brought more cold air in from the north. Snow levels dropped to 1,000 feet across far northern California and into Oregon.
