WATCH: Final accumulation update before storm arrival

Weather

**PINPOINT WEATHER ALERT**
WINTER STORM WARNINGS in effect for the entire area through Sunday afternoon.
Click “PLAY” on the video above for a complete analysis of storm timing, impacts, and expected accumulation.

STORM TIMING
Snow will begin early Saturday morning and will be isolated to start. Expect widespread, steady snow developing around 12PM. One exception may be southern Columbiana County. A mix of freezing rain and sleet is possible for southern parts of Columbiana county between 3PM & 11PM. If the rain/snow line can nudge into the county, that would delay the start of accumulating snow in that area.

Everywhere else across the area is expected to see steady snowfall all afternoon and evening. The snow will be heavy at times. Snowfall rates of 1″ to 2″ per hour are possible. We will go into the night with heavy snow continuing. Snow will begin to let up Sunday morning, between 7AM and 10AM. Once the snow wraps up by late-morning, we will be monitoring the lakes. Lake effect snow is possible Sunday afternoon and evening which could result in a few additional inches. The challenge will be the amount of moisture in the air. Cold, dry air will be in place and the lakes may not be able to provide enough moisture to feed the snowbands.

ACCUMULATION FORECAST
Current confidence level is very high for major accumulation for the majority of the area.  

EXPECTED ACCUMULATION: 8″ to 13″  –  The majority of the area is expected to see around 8″ to 13″ of snowfall between Saturday morning and Sunday afternoon.

On The High End: Up to 15″  –  A few isolated areas may see upward of 14″ to 15″ by Sunday evening.

On The Low End: 5″ to 7″  –  The area that may see the low end of accumulation would be southern Columbiana County. If the rain/snow line can push into southern Columbiana County, that may be enough to drop accumulation numbers below the expected accumulation range above. 

Temperature, Wind and Wind Chills
A surge of Arctic air will move into the area on the backside of this storm system. Highs Saturday will be in the lower 30s. Temperatures then begin dropping fast Saturday night. By Sunday morning, expect temperatures dropping into the middle teens. We will fall into the single digits by Sunday evening, with a low around 1° Monday morning.

The cold will be accompanied by very gusty wind. Wind gusts pick up overnight and will be able to gust up to 30 MPH Sunday morning and through the day. The gusty wind will cause blowing and drifting snow. This may cause roadways to re-cover after crews clear them.

The wind will also drive wind chills below 0°. We will see wind chills between -5° to 10° Sunday morning. Wind chills fall to -10° to 0° Sunday afternoon and evening. Wind chills will continue falling, dropping to -20° to -10° overnight Sunday into Monday morning. 

STORM IMPACTS
Travel
Travel will become difficult by Saturday afternoon, with driving being extremely difficult if not impossible Saturday night. Even through the snow ends by Sunday afternoon, it will still take road crews some time to clear all the side streets. Expect difficult travel through Sunday evening.

Sporadic Power Outages
Sporadic power outages are also possible with the gusty wind on the back side of the storm. The risk for outages begins to climb Saturday night as wind gusts begin rising. Through the day Sunday, spotty outages will be possible. Winds begin to die down late Sunday night into Monday morning.

Cancellations and Closures
Widespread event and business closures are expected this weekend. We will likely see adjustments beginning Saturday late-afternoon and especially Saturday night. Closures and cancellations are expected Through Sunday evening. You can check the latest cancellations and closures by Clicking Here.

Blowing and Drifting Snow
Blowing and drifting snow will be likely by Sunday morning and through the day. This can cause difficulty seeing roads and can cause them to become snow covered again after already being treated.

Shoveling and Plowing
This will be enough snow that you will have to shovel or plow to dig out. Please keep your health in mind before stepping out to dig out. If you are not used to physical activity, take frequent breaks and be careful not to over do it. These types of snow events often lead to an up-tick in 9-1-1 calls due to heart complications. If you are not used to physical activity and begin feeling sharp pains in your chest while shoveling, stop what you’re doing and IMMEDIATELY call 9-1-1.
