INDIANAPOLIS, Ind. (WLFI) - The National Weather Service is rolling out a new winter weather warning this year. It will cover a condition known as a "snow squall".
Snow squalls are periods of heavy localized snowfall typically lasting less than one hour. They are often seen with strong cold fronts.
Near whiteout conditions will also be required for a warning to be issued. This occurs when visibility drops below a quarter mile.
Snow squalls can seriously affect road conditions for short periods of time. They can become slick in a matter of minutes during a snow squall.
Warnings will be issued in thirty to sixty minute time intervals.
These warnings were scheduled to go into service nationwide last year, but additional testing postponed the launch.
