Poor dispersion is expected once again from late this evening through early Friday morning. However, some cloudiness is expected to limit fog development late tonight to the south and east Midlands, where low-level moisture will be higher with less cloudiness. Surface winds Friday will be from the southwest at 5 to 10 mph after daybreak, then increase to around 10 mph by afternoon. Transport winds will become west-southwest at 10 to 15 mph. Relative humidities will drop into the 50 to 55 percent range.
