PM Update: First Friday morning fog, followed by warm, fantastic sunshine

Extremely dense morning fog was eventually overcome by the strong late March sun and incoming flow from the south. Temperatures responded by warming into the mid-to-upper 70s around D.C. to the low 80s towards Fredericksburg . Fog returns early Friday - but not as extensive as today. The balance of Friday is partly to mostly sunny and probably a bit warmer than today.

Through Tonight: Partly cloudy skies for much of the night, with patchy fog developing pre-dawn. Lows range from 56-61 (suburbs-city) - warmer than our average highs yet again.

Friday: Any early morning fog burns off - probably faster than today - by mid-morining. Then it’s mostly sunny through mid-to-late afternoon. Towards evening, some high clouds increase with highs around 80. Winds are light.
