What Has Changed

Decreased afternoon dewpoints the next few days. Decreased central Ohio temperatures tonight and added patchy frost. Added river valley fog and fog across northern portions of the region.

Key Messages

Discussion

KEY MESSAGE 1)

Continued the trend of decreasing dewpoints during the afternoon hours the next few days. Also decreased the temperatures again across central ohio east of Columbus and added patchy frost in. Will continue to highlight frost in the HWO as well across this area. With winds off of the lake also will have the potential for some fog across the north in addition to river valley fog. Have mention in the HWO for fog across the north.

Otherwise, dry conditions are expected through at least the middle of next week. High temperatures will be in the 60s and 70s and lows in the upper 30s to low 50s.

Aviation

Calm and clear conditions tonight could lead to some BR/FG formation prior to sunrise mainly at KILN and KLUK. Any visibility restrictions mix out during the morning hours. Light easterly flow persists.
