Good Wednesday morning on what could be quite the blog post on the coldest air of the season looming, and the possibility of a White Christmas. Let’s start with the first day of Winter is tomorrow and begins at 11:28 am EST, 10:28 am CST. Weather for today, with the exception of rain chances in southern Kentucky and into West Virginia will be quiet and quiet region wide. Then we will watch two fronts that will filter in the coldest air we have seen so far this season. The first front will bring rain chances to the region, with the potential of a rain/snow mix for northwest Indiana. The Arctic front will move through the region on Saturday and behind this front will bring a changeover from rain to snow from northwest to southeast and could also produce accumulation.
As far as the potential for accumulating snow and the chances of a White Christmas, any snow that accumulates will stick around with the very cold that will move in and that will be posted in the next section, with that in mind, there is still a lot of uncertainties in how much snow could fall, so I have highlighted the areas where a light snow accumulation is possible between Saturday and Sunday night. This is highly likely to change so be sure to stay tuned for future forecasts and updates.
Finally, a look at the temperatures for the next week, most of the region will see the highest temperatures on Friday or Saturday and they will bottom out for the second half of the weekend into next week. Temperatures for portions of Indiana and Ohio by Tuesday will likely not make it out of the teens with lows in the single digits and even subzero depending on the amount of snow cover. Wind chills could be well below zero, so we are talking about some very cold air that will be moving in and we will have safety tips on the cold in future posts on the Facebook page. Below is the temperature for select cities in the Ohio Valley.
We will continue to monitor weather data in the coming days as far as snow potential and the incoming Arctic air mass.

Good Monday afternoon, we will be watching another clipper system and arctic cold front approach and move through the area tonight into Tuesday morning, then we will be watching for lake effect snow across portions of the Ohio Valley that could dump up to a foot of snow in some places. First here is a look at the watches, warnings, and advisories that has been posted, but won’t take effect until early Tuesday morning…
A quick look at current conditions as of 3:30 pm, showing some snow across portions of northern Ohio at this time, some light rain may be mixing in at times. Temperatures are ranging from 28 degrees in Ravenna, OH to 60 degrees in Paducah, KY.
Now taking a look at how the radar could look like from 7 pm this evening to 7 am Wednesday, snow will begin to gradually move into the Ohio Valley and increase in coverage through the evening hours. Snow will overspread northern and portions of central Indiana after midnight and move into Ohio by 1 am and western West Virginia by 4 am. As winds turn to the northwest, the lake effect machine will begin to crank up and bands of heavy snow will begin to develop across portions of northern and eastern Indiana, northern Ohio and possibly into portions of northeast Kentucky and West Virginia. These lake effect snow bands will continue throughout the day on Tuesday into Tuesday evening and gradually winding down by early Wednesday morning.
By the time the snow winds down by Wednesday morning, some areas in northwest facing lake effect favored areas could see at least 6 inches of snow, especially across portions of northern Indiana and northeast Ohio, with lesser amounts to the southeast. Higher snowfall totals will be in bands along a small area. Snowfall totals of 1 to 2 inches, with isolated higher amounts will be possible outside of the lake effect snow favored areas. In addition, more cold air will filter in behind this front and temperatures, especially in the northern Ohio Valley will remain in the 20s, combined with winds that could gust up to 35 mph at times, wind chills will be in the single digits. We will have forecast wind chills on the Equinox Weather Facebook page shortly. More information will also be available there.
Good afternoon, taking a look at current conditions across the Ohio Valley, clouds are beginning to increase across the area from Indiana eastward to Ohio, lots of clear skies in West Virginia. Temperatures are generally in the 40s and 50s across the Ohio Valley.
Taking a look at FutureCast from 4 pm this afternoon through 7 am Saturday morning will showers and embedded thunderstorms begin to increase in coverage and in some cases intensity. Showers will begin to move into Indiana in the early evening hours and thunderstorms may enter into the picture between 7 and 9 pm. Showers and embedded thunderstorms will continue to spread eastward and move into western Kentucky and Ohio by the late evening hours into the very early morning hours of Saturday morning. Showers at times may be heavy and some of the stronger storms may produce gusty winds and small hail. Heavy rainfall will move into the Cleveland area by 2 am and around the same time, some lighter rain will begin to move into western West Virginia. Showers and storms will begin to become more scattered about for Indiana. By 5 am, heavier rain will move into the Charleston area and by the end of the period will move into eastern West Virginia, while more scattered showers and embedded storms will continue for much of Indiana, central Kentucky, and western Ohio.
Heading into Saturday, there is a marginal risk of severe storms for much of central and southern Indiana, much of Kentucky, and southwest Ohio as a cold front approaches the area. While there will be lack of instability with this cold front, dewpoints will increase in the upper 50s and a strong low level flow will be sufficient enough for thunderstorm development, in which a few storms could produce damaging winds. This will not be a widespread potential by any means, and most areas will not see severe weather, but anyone within the marginal risk area could see isolated damaging winds.
We will continue to monitor the situation even we are not anticipating a widespread event. For further updates, please like the Equinox Weather Facebook page.
