The National Weather Service is forecasting 18 to 24 inches of snow to fall in the city, which would make it one of the top 10 snowstorms in Philadelphia history. Though it’s not expected to top the nearly 31 inches of snow that blanketed Philly over a two-day period during the Blizzard of 1996.

Philadelphia, Bucks, Delaware, and eastern Montgomery Counties, and all of New Jersey and Delaware, are currently under blizzard warnings through 6 p.m. Monday. That’s prompted by forecast wind gusts of up to 45 mph, combined with the heavy snow. The western suburbs are covered by a winter storm warming, with slightly lower wind speeds forecast.

The storm is expected to begin as rain before shifting to snow by midday Sunday. It’s forecast to strengthen overnight, possibly at a rate of more than 2 inches an hour, which would make driving dangerous and nearly impossible.

The last time the city experienced more than two feet of snow was 2010, when nearly 29 inches fell in early February 2010. Over a five-day period, the city was buried under 44 inches of snow, which thankfully isn’t expected this time due to a warm-up in the middle of next week.

This time around, the Jersey Shore is expected to be hit hardest, with snowfall totals in and around Toms River forecast to reach as high as 30 inches.

The National Weather Service puts out forecasts for every few square miles of land in the United States four times a day through a system called the National Digital Forecast Database.
