Crazy, extreme weather leads up to Thanksgiving
Where are Wednesday's travel trouble spots?
The combination of a massive Arctic outbreak out West, a warm surge in the East and powerful storm in the transition zone is wreaking weather havoc as the Thanksgiving holiday approaches. Even Alaska is contending with unusual weather, as unseasonably mild air bumps up to the Arctic circle, bringing widespread rain and ice rather than the customary snow.
Check out these examples of weather extremes I've aggregated from the past, present, and projected future (areas impacted in bold test):
TODAY'S WEATHER TROUBLE SPOTS
Weather.com - "Dangerous travel in the West with wind & snow. Blizzard warnings in E. WA, ID, W. MT, UT, NE. NV, W. CO."
National Weather Service, Salt Lake City - "A high confidence forecast for a very strong system that will produce potentially dangerous winds...heavy snowfall...and whiteout conditions that will make evening travel treacherous [around Salt Lake City]."
National Weather Service Fairbanks, AK - Winter Storm Warning - "Freezing rain will continue through Wednesday. Additional ice accumulations of up to one half inch is expected...with storm total ice accumulation up to 1 inch."

WEDNESDAY'S TRAVEL TROUBLE SPOTS

Minnesota - Meteorologist Paul Douglas at the Star Tribune in Minneapolis says: "The latest guidance is hinting at 2-5" of snow for the metro (closer to 5" if we don't see as much sleet/rain as I'm expecting). Parts of central MN may pick up 4-8" with over 10-12" closer to Duluth. North metro will probably pick up more snow than south metro (where rain/ice may linger a couple extra hours - keeping final snowfall tallies lower)." He adds: "There is a risk of blizzard conditions across parts of the metro between 3 pm and 9 pm tomorrow. Winds may reach 30-40 mph, a thin layer of ice under (rapidly) accumulating snow."
North Dakota - National Weather Service forecast for Bismarck: "Snow and widespread blowing snow. High near 16. North wind between 7 and 16 mph, with gusts as high as 23 mph. Chance of precipitation is 80%. New snow accumulation of 1 to 3 inches possible."

Chicago Tribune - "[Monday's] weather turned wild across sections of the Midwest. Fast-moving thunderstorms raced through the area at dizzying speeds, turning tornadic as they raked across areas east of Rockford. The day's record warmth played a role in super-charging the storms."
Our Amazing Planet - "In Wisconsin, the first November tornado in more than 39 years -- which boasted an EF1 strength rating -- struck Walworth County. Another was reported in Union Grove, Wis., but has not been confirmed. Only three November tornadoes have hit Wisconsin since 1950 before Monday (two on Nov. 15, 1960, and one on Nov. 1, 1971)."
