From the National Weather Service office in ILN, issued 7 hrs ago

What Has Changed

Reduced afternoon dewpoints and added in river valley fog overnight the next few days. Reduced overnight low temperatures in the cool spots east of Columbus the next few nights and added in frost.

Key Messages

1) Dry conditions will persist through at least early next week.

Discussion

KEY MESSAGE 1)

Dry conditions are expected into the middle of next week at this time. Expect several continued days of similar conditions. Reduced afternoon dewpoints the next few days and also added in river valley fog. There will be the potential again tonight for some fog across northern portions of the region as well. Reduced temperatures the next few nights as well as temperatures have been coming in cooler than the NBM. Especially reduced temperatures across central Ohio east of Columbus in the typical cool spots. While a few cool spots elsewhere will have the potential for frost, limited most of the frost mention to portions of central Ohio east of Columbus. Will add frost mention in the HWO as well.

Aviation

Aside from some river valley fog at KLUK, a nne wind around 4kt tonight will become more ene and increase to 6-7kt tomorrow under generally clear skies. Opted to run with the higher values as such a small increase in both direction and strength are operationally insignificant.

OUTLOOK...No significant weather expected.
