Meanwhile, another area of low pressure was moving across the Ohio Valley and tracking eastward toward our region.

Precipitation/Temperatures/Winds Some scattered light snow showers moved into the area late Tuesday morning spreading northward through the afternoon and evening. Some mixed precipitation (snow, sleet, freezing rain and/or plain rain) was reported at the onset, especially across the southern portions of the forecast area and along the coast where temperatures were in the lower 30s, but eventually a changeover to all snow occurred across the area by late Tuesday night. Snow began to taper off from southwest to northeast and ended around daybreak Wednesday morning as the low moved further away from our area. Snowfall totals were highest across northern and central New Jersey, with the highest amounts reported in Middlesex and Monmouth Counties. Across the region, snow totals varied with 03 inches across parts of the Delmarva into southern New Jersey and along the coast. Roughly 2/3rds of the region had around 6 inches of snow or less while the remaining 1/3rd had 610 inches reported. Winds did not end up being a major concern during the storm as they remained fairly light across the region. However, as the low pressure system moved away from our area, gusty northwest winds caused some blowing and drifting of snow on Wednesday. Significant Impacts/Aspects The only impacts from this event were the usual traffic accidents associated with inclement weather as well as numerous school closings on Wednesday January 12th.
