For those that mentioned precipitation just a reminder on what the chance of rain means It DOES NOT mean the zip code you're looking at has a 20% chance of precipitation It DOES mean of the entire surrounding area of the zip code 20% of that area has 100% chance of precipitation This study falls under MEH, despite the hard work, because the most important part (precipitation) was left out. Especially considering it's winter and snow or no snow is a HUGE consideration for people to take.
