Here comes the sun…Oh, no!

Yesterday a pesky warm front trudged through the Mid-Atlantic states, heralded by low stratus. Morning temps were in the 60s in central Maryland, and it was plenty humid, of course. Things heated up by late afternoon, but not by much. A sole, random break in the clouds sent a shaft of sunlight earthward, and for a moment all seemed cheerier.

But no! As I’ve seen many times–from above and below–that sunlight warmed up the lower atmosphere and destabilized the air. The shaft of sunlight disappeared, only to be replaced by dark skies and heavy rain. A check of the satellite and radar imagery showed that that bit of sun kicked off a modest buildup. Yet more proof that sunny skies may not always mean good weather!
