The next blast of arctic air will be even colder, and will bring another round of snow.
“The cold air just keeps coming,” Storm Center 7 Chief Meteorologist Eric Elwell said. “Even while we deal with the current outbreak of arctic air, more is building near the North Pole and it is forecast to head south this weekend.”
Temperatures across the region have not been this low in nearly three years. Dayton started out Wednesday morning 2 degrees below zero. The last time it was that cold was on Feb. 24, 2015.
While temperatures will moderate some by the end of the week, it won’t last long.
Light snow is expected to spread into the Miami Valley on Friday after dark and linger into the start of the weekend.
“While it is not expected to be a major winter storm,” Elwell said, “we could get an inch or two of snow ... due to the higher liquid to snow ratio.”
In other words, it doesn't take as much moisture for the snow to fluff up when temperatures are so low, Elwell said.
Some flurries may even linger into New Year's Eve day.
Our Storm Center 7 team of meteorologists will be working through this week to pinpoint the timing and amounts of this next storm. If you have big plans on New Year's Eve, be prepared to bundle up. The fresh batch of bone-chilling cold will have arrived and temperatures likely will be in the single digits as the clock strikes midnight.
“Wind chills will likely be as cold as 5 to 10 degrees below zero,” Elwell said, likely making it the coldest New Year's Eve since at least 2002.

— QUICK-LOOK FORECAST
Today: It will be a quiet and cold morning with temperatures in the 30s, said Storm Center 7 Meteorologist Kirstie Zontini. There will be some sunshine early with clouds increasing late day. It will be dry during the day and warmer than normal with highs in the mid-50s. Some rain showers will start to arrive from the south later tonight. Cold air will cut in and a wintry mix will develop toward morning.
Tuesday: Spring starts at 12:15 p.m. with the vernal equinox, but it certainly won’t feel like spring. A wintry mix is possible, and anything untreated or elevated could become slick as temperatures will start out in the upper 20s. Any surface below freezing could see some light freezing rain. Moisture will continue to stream into the Miami Valley. A rain/snow mix is possible in the afternoon with temperatures in the 30s and low 40s. It will become breezy. Scattered snow will take over into the evening and continues overnight. Winds will gust around 25 mph.
Wednesday: Scattered snow showers will be falling and will likely create a slick morning commute. Snow will not taper off until the evening hours. Highs will be in the mid-30s. Accumulating snow is expected by morning and through the day. The placement and intensity of this system can still change, but snow is expected to coat the roads by morning and will continue to accumulate during the day. It will be dry for the night, but it will be cold as temperatures drop into the mid-20s.
Thursday: There may be a lingering slick spot in the morning. The day looks to be dry and back into the mid-40s. There will be some sunshine as well.

— During the winter months you may often hear about snow, sleet and freezing rain.
Each has its own hazards, but freezing rain can create hidden dangers on the roads, more than the others. Unlike snow or sleet on pavement, freezing rain can appear wet, but is actually a sheet of ice and will leave no traction for drivers.
Freezing rain forms in the clouds just like snow, but it’s what happens after the snowflake leaves the cloud that changes everything. During a freezing rain event the air within the cloud is cold enough to produce a snowflake.
If the snowflake falls into air below the cloud that is above freezing, it will melt into a raindrop. This droplet will continue to fall as rain as long as the environment remains above 32 degrees.
Since cold air is more dense than warm air, sometimes a thin layer of subfreezing air may settle to the surface cooling the ground. If this occurs, once the droplet hits anything that is below 32 degrees it will freeze on contact. Typically, elevated objects such as trees, overpasses and power lines are the first to accumulate ice. If freezing rain continues for an extended period of time, ice may become so thick that numerous accidents and power outages may occur.

— A storm system will approach the Miami Valley just in time for St. Patrick's Day, said Storm Center 7 Meteorologist Brett Collar. Early Saturday morning the system will bring freezing rain and possible ice acccumulation.
Slick roads and icy sidewalks could be an issue beginning at 4am Saturday, and last through noon.
Prior to sunrise Saturday, freezing rain is set to move in from the west. This will become more widespread around sunrise and that’s when ice accumulation will start to become a big issue. This will continue through the morning hours but by 10am or 11am, we should start to see a transition over to rain as temperatures climb above freezing. Untreated surfaces however are likely to still be icy through lunch time.
