Two storm systems will bring the chance for accumulating snow to the region this week. The first will be a fast moving, weak upper level disturbance on Wednesday. The next will be a stronger storm on Friday but many questions still remain with that system.
With clear skies and winds going somewhat calm overnight, temperatures are expected to drop again. With the wind much more calm, the wind chill will actually not be as bad on Tuesday morning. Expect values between 0 and -8 degrees. The actual air temperature may drop a couple degree farther though which will put almost everyone very close to zero. Some outlying areas will likely drop just below zero.
Even with some sunshine on Tuesday, temperatures will struggle to get to 20 degrees. We will see an increase in clouds Tuesday night which will keep temperatures a little “warmer” in the balmy middle teens.
The previously mentioned disturbance for Wednesday will be knocking on our doorstep early in the morning. Light snow is expected to start around sunrise and persist through early afternoon. With dry arctic air lingering nearby, it may be hard to get deeper moisture involved to crank out better snow production. For that reason, only about an inch or so of accumulation is expected. Some isolated spots could see closer to 2 inches, but around 0.5 to 1.5 inches is expected in general.
There will be a minor impact to travel especially considering how cold road surface temperatures are. Bridges and deep valleys are the most likely to be impacted. However, any surfaces could see some slick spots, so keep that in mind if you will be out during the morning or afternoon hours on Wednesday. Temperatures will only get into the middle 20s which will only slightly help salt to function better.
Temperatures will drop into the teens again Wednesday night before rising to near 30 on Thursday. A mix of sun and clouds is expected with dry conditions.
Attention then turns to the next more significant winter storm that is poised to impact much of the Eastern U.S. on Friday. As is often the case for Cincinnati, the exact track of the storm will have a large impact on our snowfall outcome. A slightly more northern track would bring heavier snow into the region whereas a slightly more southern track would just graze the Tri-State. There may end up being a tight gradient of snowfall with areas east and south of Cincinnati currently in the best position for larger amounts.
The potential exists for several inches of snow to fall, but there is still plenty of uncertainty. It will be a system to watch over the next few days as we get closer. In fact, the exact track of the weaker system Wednesday may impact the track of the system on Friday as the first storm lays down the foundation in the upper atmosphere that could ultimately determine how far north the second one goes.
The weekend is looking seasonably chilly and quiet for now. Some more rain and snow showers will re-enter the picture as we start next week.
