The following quote from Accuweather illustrates just how localised snow squalls really are.
"An impressive 5-foot snowfall total has been measured in Lancaster, New York, a suburb of Buffalo as of Tuesday night with similar amounts across the Southtowns. However, due to the nature of these snow bands, some areas can get pummeled, while others escape the intense snow. For instance, the Buffalo airport has only received 3.9 inches of snow while a few miles to the south, several feet fell."
