The featured chart shows the GFS Model Output Statistics (MOS) value for probability of precipitation for Ames this month. Each bar represents a different model run's 36 hour forecast. The chart shows how small our rainfall chances have been this month, but Monday and Tuesday have the largest values seen this September. In fact, rain showers are currently in Western Iowa, so getting rain today looks to be a good bet.
