Clouds then Rain
Posted: 09 Jul 2014 05:41 AM
Skies were mostly fair on Tuesday with even the 4 AM observation reporting "clear" from
the automated airport sensor in Des Moines. The featured chart looks at the frequency of
having measurable precipitation for the midnight to 8 AM period the day following an hour
with a given cloud coverage reported. In general, having overcast skies have more
frequent rainfall events than clear skies which makes intuitive sense. Of course you have
to have clouds for it to rain, so having overcast conditions later in the day leading up to the
next day increases the frequency and having clear skies decreases the frequency. The
overall frequency of having rainfall sometime during the 12-8 AM period in July is around
15%.
