TIMING: Light snow will begin overnight Saturday night into early Sunday. The heaviest accumulating snow will be between 10 a.m. and 6 p.m. Snow will taper off after midnight Sunday night.

ACCUMULATION: Most locations near Columbus will see 4-6” with isolated pockets of close to 7” possible. A very light glaze of ice from sleet at the onset of precipitation Saturday night is also possible. Expect less snow as you travel north of Columbus and more snow as you travel south.

IMPACT: Moderate. Roads will become hazardous particularly after late morning Sunday through the evening hours. The morning commute may also be slick on Monday.

Discussion:

After a convoluted 48-72 hours of forecast models, the details for this winter storm are starting to be hashed out. As previously mentioned in recent discussions, the main question was if the second wave of snow would hit Columbus Sunday night. It appears this will not be the case and thus a moderate snowfall is forecast rather than a major storm. However, accumulating snow is still likely and will cause problems on the roads.

An arctic high pressure system will ooze cold air at the surface into Ohio tonight dropping the temperature significantly from this afternoon. Highs today hit the upper 40s while highs tomorrow will barely hit the middle 20s! Expect light to moderate snow to fall most the day with the heaviest during the middle of the afternoon.

With snow falling during the middle of the day, this could act to limit accumulations slightly. An offsetting factor may be that the liquid to snow ratio will increase throughout the afternoon meaning we can squeeze out a little more snow. This will in part be due to maximum lift in the favorable snow growth layer of the atmosphere and due to the very cold arctic air mass filtering into the region.

Snow will come to an end before sunrise on Monday. It will remain cold with highs in the 20s and lows well into the single digits on Tuesday morning. The air mass will slowly modify throughout the week as highs head back into the 40s by week’s end. Stay with Examiner.com for the latest snow updates.
