Checking weather-—temps are mild in Iowa and no precip until after the whole caucus thing would be over. Any Iowans here who can confirm?
Weather in Iowa will not affect the caucuses.
It’s 40 degrees and bright sunshine in the Des Moines area.
There’s a swath of northwest Iowa that might get a little rain/snow/mix around caucus time. That’s Steve King’s congressional district and likely Cruz country. They would turn out the same in a real blizzard.
