What causes a $60^ ext{o} ext{F}$ day under full sun to feel warmer than one on an overcast day?

Answer

Direct solar radiation warming skin and surfaces

Direct solar radiation passes through the atmosphere and warms surfaces like skin, pavement, or clothing directly. When clouds block this radiation, the heat felt shifts primarily to the convective transfer from the air itself, resulting in a cooler sensation.
