Afternoon showers

Posted: 07 May 2009 06:12 AM

The featured graph is a timeseries of the areal coverage of NEXRAD base reflectivity returns based on IEM generated composites. The values represent the percentage of the state covered by precipitation over time. Yesterday afternoon saw afternoon showers pop up due to daytime heating. This plot nicely shows how the peak coverage of storms occured around the time of peak heating from the sun (when the sun is the "highest" in the sky. Coverage amounts then decrease until sunset. More showers are expected today.

Good = 41
Bad = 25
