Convection Killer

An overcast deck of stratocumulus in the morning can really ruin a perfectly good (but inaccurate) forecast for afternoon convection. Such stratocumulus is typical in the warm and humid air mass. The same moisture that creates the huge instabilities conducive to severe convection, also promotes low deck stratocumulus. As I was signing my name, the sun started to peak between the stratocumulus as it continued its transformation into cumulus due to the ongoing daytime heating.
