Expected aspects of the storm

Timing: The timeframe to watch is Thursday evening through Friday morning. Thursday evening, temperatures will be in the upper 30s and lower 40s, and rain showers will be possible. As colder air quickly crashes in, precipitation will go from rain to snow. Snow will remain possible through Friday morning.

Wind: Winds may gust as high as 50 mph on Friday. This could lead to isolated power outages. It may be a good idea to bump the heat up in your house a bit Thursday night, just in case you lose power for some time Thursday night into Friday.

>>Lose power in the cold? Here’s what to do

Wind Chills: Wind chill values will drop well below zero on Friday. The National Weather Service is suggesting these could be as low as -30. That is dangerous cold, and can lead to frost bite in as little as 30 minutes. You’ll want to limit your time outside on Friday.

Flash Freeze: The combination of rapidly dropping temperatures along with moisture on the roads from rain and snow will lead to flash freeze potential. Road conditions may quickly change from wet to slick in a short period of time Thursday night into early Friday. Be aware of this if you must travel during this time.

Precipitation Type: Rain, wintry mix, and and flurries are expected, then all snow.

Cold: Temperatures will be in the teens and single digits Friday through Sunday night.

Snow Totals: Snow will amount to 1-3″ with isolated 4″ across the Miami Valley. This will not be a huge snow producer for us in terms of amounts, but this snow will still be impactful to travel. It will be of the powdery variety. That combined with wind will lead to roads remaining snow covered, Chaney said.
