expect similar
scenario unfold as
layer decouples
The atmosphere has changed little today with warm, moist conditions in place. Conditions tonight into Tuesday morning will be largely be similar to those found this morning where widespread fog and stratus were common along the coast. Expect a similar scenario to unfold tonight as the boundary layer decouples, but there is a large number of discrepancies on the timing and coverage of stratus and eventually fog as much depends on the amount of mid- level clouds that some guidance members suggest will develop. If an expansive area of mid-level clouds forms, this will tend to lower to dense fog threat. For now, the forecast has been trended closer to the more pessimistic guidance given the mostly favorable conditions in place and the anticipation of stratus transitioning to fog via stratus build-down. Areas of dense fog were highlighted for most areas south of I-26, but refinements to the fog forecast will most certainly be needed later tonight as additional data are received and observational trends are established. A Dense Fog Advisory may be needed for some areas later tonight. Lows Tuesday morning will range from the upper 40s/lower 50s well inland to the upper 50s/near 60 at the beaches.

I guess I expected more from when the weather service said, “Expect a similar scenario to unfold tonight as the boundary layer decouples, but there is a large number of discrepancies on the timing and coverage of stratus.”
