July Clouds and Visibilities

Posted: 15 Jul 2022 05:37 AM

The featured chart presents the hourly cloud and visibility reports for this July from Des Moines. The top panel attempts to replicate the sky condition by showing reported clear skies as blue and increasingly darker colors with lower and higher coverage cloud amounts. The skinny panel shows the horizontal visibility amount. The gloomy days just over a week ago are readily apparent along with the periods without reported clouds. Automated station reports of clouds are fraught with caveats including limits on how high up the sensor can "see" clouds. The forecast has a mix of clouds and sunshine for the weekend and then sunny/hot conditions for next week.
