Columbus weather forecast: Patchy dense fog returns overnight, slick spots possible

Weather

Wishing everyone a Merry Christmas and Happy Hanukkah!

Thick fog formed as expected Christmas Eve, and never really lifted in the northern part of the state all day, after a very foggy morning.

The dense fog advisory has been expanded overnight into Christmas morning in many parts of central, northern and eastern Ohio.

Fog is a cloud on the ground that forms above moist ground, with light winds, resulting in cooling a shallow layer of moisture, which condenses into fog droplets.

The fog has stayed fairly dense north of Columbus through this evening, and will overspread much of the state again overnight, reducing visibility to near zero in some areas, so please exercise caution when traveling on Christmas Eve.

Expansive high pressure entrenched in the East and extending back to the midsection of the country will promote fair weather and a mild southerly flow through the week. Another weak cold front will slip south on Thursday, bringing an increase in clouds but little in the way of chillier air.

The buckled jet stream will force Western storms around the ridge, tracking from the Mountain West to the adjacent Plains, while keeping us shielded from rain. Later in the weekend, the pattern will shift and rain will arrive, followed by seasonably cold weather next week.

Christmas Eve: Dense fog developing, slick spots. Low 29

Christmas Day: Morning fog, mostly sunny, breezy, mild. High 56

Thursday: Mostly cloudy. High 58 (40)

Friday: Clouds, still mild. High 55 (43)

Saturday: Overcast, breezy, rain at night. High 55 (40)

Sunday: Showers, mild. High 50 (42)

Monday: Brisk, colder, flurry. High 38 (33)

Have a wonderful holiday! -Ben
