Here's a breakdown of what you need to know to get through the weekend:

Heavy rain: Today and this evening heavy rain and storms will move through. Minor flooding and ponding on the roads can be expected. 

Wind: Wind will be gusting this afternoon and evening. Winds more than 40 mph outside of any storms can be problematic. Isolated power outages are possible. Holiday decorations and lawn furniture could be blown around or damaged. Driving also will be difficult because of the strong winds, so leave space between you and the cars around you.

Accumulation should not be an issue, but there may be some isolated slick spots on bridges and overpasses.

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.

Friday: It will be a dry and quiet morning. Clouds will increase through the day. Highs will be in the mid to upper 40s. Clouds will increase at night with rain showers returning.

What is freezing rain and how is it different from snow and sleet?

Published: Friday, March 16, 2018 @ 2:31 PM

What is the difference between rain, freezing rain, sleet and snow? Meteorologist McCall Vrydaghs has the answers.

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. 

WHIO Weather App

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.

Meteorologist Kirstie Zontini breaks down the next system that can impact your St. Patty's Day.

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.

  • Back roads and sidewalks may be untreated
  • Be aware of slippery surfaces if starting your party early
  • Winter Weather Advisory early Saturday so wear an extra layer for outdoor festivities. 


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.
