Iowa and four other states were directly in the path of a massive snowstorm barreling across the Plains on Monday, but it's not going to bury the Hawkeye State until after most of the caucusing is over.
"The southwest corner of Iowa is most likely where the caucuses will be affected by light snow, but the storm should not impact most places," Weather Channel Lead Meteorologist Kevin Roth told NBC News.
Still, the storm is likely to pack a wallop in the five states under blizzard watches and warnings, dumping up to 18 inches of snow and snarling traffic for millions. And it remains to be seen whether the threat of bad weather will keep Iowans from the caucus sites on Tuesday.
Although the largest snow totals were expected in rural areas, Iowa's biggest city, Des Moines, is expected to get socked with anywhere from 6 inches to a foot of snow through Wednesday. Similar amounts of powder are in the forecast for Denver, Omaha and Green Bay, forecasters said.
