(Updated Sunday afternoon)
A Dense Fog Advisory was in effect for parts of south-central and southeast Virginia Sunday morning until 8 a.m. Air temperatures and dew point temperatures were very close to each other this morning, which put relative humidity values in the 90% range. Patchy fog also occurred in the Richmond area. Winds increased in speed by mid-morning, though, which helped to mix the air near the surface and disperse the fog. Drizzle and light rain showers will continue to be possible today, but chances in Richmond are low through the afternoon.
High temperatures today will climb to the upper 60’s and low 70’s in Central Virginia before the cold front passes tonight. Average highs for late December are in the mid to upper 40’s. The record high for December 28 in Richmond is 77 from 1984, so today’s high will be on the upper end of our range of recorded temperatures in late December.
This unseasonably warm weather will end with the frontal passage, putting our temperatures back closer to average levels into New Year’s Eve.
