The expansive major winter storm that has produced a myriad of hazards over the last couple days, including but not limited to heavy snow, crippling ice accumulations, flash flooding, and severe weather will enter its third and final day before exiting stage right into the Atlantic Ocean this weekend. More heavy snow is forecast across northern New England today with the heaviest accumulations in eastern Maine where over 6 inches of snowfall is expected. A little farther south, where surface temperatures are plummeting below freezing but milder temperatures at mid-levels of the atmosphere are also present, an icy wintry mix is expected to cause slick travel conditions for the morning commute from the interior northern Mid-Atlantic to the more urbanized I-95 corridor from Boston to New York City. Parts of central Massachusetts could receive as much as a quarter inch of ice by the time the storm exits off the coast this afternoon, while even parts of the northern Mid-Atlantic could receive as much as a tenth of an inch of ice accumulation. Light snow accumulations remain possible in parts of the upper Ohio Valley this morning with bitterly cold temperatures continuing to filter into the region throughout the day. Farther south, scattered showers and thunderstorms are possible from southeast Virginia to northern Florida with some thunderstorms potentially becoming severe. In wake of this week's massive winter storm, frigid temperatures courtesy of a large dome of Arctic high pressure is becoming firmly entrenched from the Rockies and throughout the Heartland today. Morning lows ranging between the single digits and below zero are anticipated up and down the Great Plains with the coldest temperature anomalies located "Deep in the Heart of Texas". Blustery winds combined with the abnormally cold temperatures have prompted the issuance of Wind Chill Warnings and Advisories across much of the Southern Plains. In fact, temperatures are so cold that Winter Storm Warnings remain in place for parts of the Deep South where lingering icy roads are still a concern for the Friday morning commute. Scattered snow showers tracking through the Mid-South may also lead to hazardous travel conditions this morning. By Saturday morning, the troublesome winter storm finally exits off the East Coast, but bitterly cold temperatures look to stick around with some temperatures challenging record lows in the South Central U.S.. Milder temperatures return to parts of the North Central U.S. Saturday and Sunday, but the Arctic high then slides over the eastern U.S. making for a frosty first weekend of February in the northeast quarter of the Lower 48. Elsewhere, the weekend weather pattern becomes more tranquil thanks to a pair of large high pressure systems setting up shop over the eastern third of the U.S. and along the West Coast. Sandwiched in the middle is an upper level disturbance and an associated low pressure system traversing the Northwest this afternoon and reaching the Northern Plains by Saturday. Mountain snow and valley/coastal rain are on tap for the Pacific Northwest as well as strong winds in parts of Montana, leading to the issuance of High Wind Warnings and Watches for parts of "Big Sky Country" late Friday into early Saturday. Periods of snow are expected from North Dakota and northern Minnesota Saturday morning to the Upper Great Lakes Saturday night into Sunday morning. The heaviest snow totals (exceeding 6 inches) are most likely in Michigan's Upper Peninsula. Aside from some areas of mountain snow in the northern Rockies and scattered showers in Florida, Saturday appears mostly dry for the remainder of the country.
