High temperatures on Thursday are expected to be rather chilly in the lower 50s. Such levels are rather rare for the month as shown by the featured chart presenting the daily frequency of having a sub 55 degree high temperature for Ames. Overall, we'd expect to only see one day for the entire month at this cold of a level. If it comes to fruition, this would be the second day this May below 55 (1 May being the other).
