What happened

The episode as NWS CLE wrote it up.

Cold northwest winds blowing across Lake Erie caused lake effect snow showers to develop during the late evening hours of January 3rd. The snow showers picked up in intensity during the early morning hours of the 4th. Periods of moderate to heavy snow then continued into the 5th. The worst of the snow was during the afternoon and evening of the 4th when visibilities were less than a half mile at times with snowfall rates greater than an inch per hour. The intensity and coverage of the snow showers diminished on the 5th with the snow ending completely by early evening. Northwest winds gusted to as much as 25 mph during this event causing much blowing and drifting. Some locations saw more than a foot of snow with most of it falling on the 4th. In Erie County the heaviest snow fell inland from Lake Erie with a peak total of 13.0 inches at Edinboro. In Crawford County, most of the snow fell across the northern third to half of the county. A peak total of 18.7 inches was measured just south of the Erie County line near Drakes Mill. Other totals from Crawford County included 14.0 inches west of Meadville and 11.9 inches near Cambridge Springs. Some accidents were reported during this event.
