The weather pattern that has enveloped the Miami Valley can be very conducive to "clipper systems". These storm systems originate from Canada and move rapidly across the Great Lakes. They usually bring quick bursts of light to moderate snow along with gusty winds. They also typically bring a rapid drop in temperatures after they move by.

But there are several different names given to these clipper systems depending on where they originate. 

The most common Canadian storm system is called the "Alberta Clipper."

But there also are two more names if the systems develop in the Canadian provinces of Saskatchewan and Manitoba. 

Storm Center 7 Chief Meteorologist Eric Elwell explains the differences between an "Alberta Clipper," a "Saskatchewan Screamer," and a "Manitoba Mauler" in this video.

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.
