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.

St. Patrick’s Day: Freezing rain could impact celebration

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.

WPAFB Friday Weather: Blustery start; wintry mix to develop early Saturday

RELATED: 5-Day Forecast

Temperatures will begin in the lower 20s by climb back into the lower 40s during the afternoon. Clouds will increase tonight as a storm system approaches from the southwest.

A wintry mix of freezing rain and sleet is expected to develop after 3 or 4 Saturday morning. This will lead to icy spots and perhaps a coating of ice on elevated surfaces to begin St. Patrick’s Day. Some snow may also mix in across the far northern Miami Valley.

As temperatures rebound from the 20s into the lower 40s in the afternoon, mainly rain showers are expected with improving travel conditions. Skies will clear Saturday night with sunshine and milder weather to end the weekend.

 Three things to look forward to this spring

Published: Thursday, February 22, 2018 @ 12:25 PM
Updated: Thursday, March 15, 2018 @ 4:17 AM

Here are a few things to look forward to as we start a new season.

We are now less than a week from the astronomical start to spring. On March 20 the vernal equinox will take place, transitioning us to the new season. 

  • Daylight: The days will get longer. Daylight Saving Time helps increase the amount of daylight but naturally the days get longer during the transition from the winter solstice to the summer solstice. From Feb. 20 to March 20, we will see an increase of a little more than an hour of daylight.                                      Latest weather video: Watch our five day forecast
  • Low Snow: The chance for snow drops off. On average, the latest we see an inch of snow in Dayton is March 10. That doesn’t mean we won’t get snow in March, just statistically speaking it becomes less likely. There will be a greater chance though for spring storms as severe weather season kicks in.  
  • Warmer: It will gradually get warmer. The average afternoon by the first day of spring is 51 degrees. The angle of the sun and the length of day helps to increase our average high. 
  • Keep an eye on your daily forecast by using the WHIO weather App.
