The snow squall warning was introduced by the Weather Service in just the past year. It was created because these squalls can generate “sudden whiteout conditions and slick roadways” that may “lead to high speed accidents with large pileups that result in injuries and fatalities,” the Weather Service wrote.

Snow Squalls :
By definition, a snow squall is an intense, short-lived burst of heavy snow that's often accompanied by gusty winds. Snow squalls cause a quick reduction in visibility and often result in a quick accumulation of snow. Lake-effect snow can sometimes qualify as a snow squall, although it's not always short-lived. The most common breeding ground for snow squalls is near strong cold fronts which mark the arrival of Arctic air in the winter.

What are some negative effects?
The combination of a quick burst of moderate or heavy snow and gusty winds can create a life-threatening situation for drivers as visibility can rapidly drop to near zero ("whiteout conditions") and roads become slippery as snow accumulates quickly.
"We haven't had too many events where these snow squall warnings have been issued. Certainly, not when I've been working to be able see it. Today, we had widespread use of that product – from West Virginia to Pennsylvania, New York and even on up to the New England states, Vermont and New Hampshire." Burke's commentary.
