Making predictions is difficult, especially about the future. However, weather predictions have begun to be a bit better in the last decade. Keep in mind that Iowa is a caucus state where people have to give up hours of their time in order to go support a candidate. Also consider now that staunch conservatives who have caucused previously are more likely to support Cruz while Trump’s supporters would tend to be new voters. Given that ask yourself what weather conditions would be ideal for each candidate to improve his relative standing, and reflect for a moment what would be a “worst case” scenario for each.
Now for what weather.com actually says:
Rain and snow Saturday, Sunday, and Monday culminating in a Monday high of 34 and 1-3 inches of accumulation on Monday before the Caucuses begin.
The forecasts may change, but this so far makes me smile.
