A major storm is likely Thursday night and Friday that will have substantial travel impacts, so good to prepare ahead of time and watch for updates as the week progresses.
Our weekend snow showers—the first measurable snow in a mild December so far–have diminished, as a large, lumbering storm over the northern Great Lakes moves east. High pressure will build in from the southwest, bringing some clearing overnight and partly sunny skies on Monday.
Temperatures will dip into the teens late tonight. Highs on Monday will only reach the mid-30s, with high clouds increasing later in the day and in a light southwest flow. The weather will be quiet to start the week. Clouds will increase ahead of a weak cold front Tuesday that will wash out, with no rain or snow expected.
A moist southerly flow will develop ahead of a developing storm midweek in the southern Plains that will interact with an arctic cold front diving south. As the storm deepens Thursday night tracking across the western Ohio Valley and Great Lakes, rain will overspread the region.
LATE-WEEK MAJOR STORM
Rain will change to periods of snow on Friday, accompanied by unusually high winds (40-50+ mph) that will cause blowing snow and a risk of power outages, with temperatures falling through the 20s into the teens. The wind chill could dip as low as -10 Friday night, so this will be an extraordinary blast of arctic air so early in the season.
Snowfall totals will be light (likely 1-3 inches), but likely enough to ensure a white Christmas for all of Ohio. As the storm lifts into Canada Christmas weekend, the wind will relax but the air will be frigid. Temperatures on Christmas Eve will dip to the single digits, and only reach the teens in the afternoon.
