Past IEM Features tagged: instability
Monday certainly felt more like spring with some passing showers in the morning and some afternoon convective showers with cumulus clouds. The featured chart displays a five minute interval time series of approximate areal coverage of 10+ dBZ RADAR reflectivity. The two peaks are clearly shown with the morning showers due to a passing storm system and the afternoon showers thanks to the heating of the day driving convection. The peak for the afternoon showers was just before 5 PM, which is about the time the lower atmosphere starts to stabilize as the sun reaches a low altitude in the sky (less effective at heating the ground).
