Milder temps in Philadelphia Thursday, 10+ inches of snow possible during weekend storm
Two quiet and mild winter days are ahead as we prepare for what will likely be the biggest snowfall in a decade.
We currently have placed the probability of 8 inches or more of snow at 90% — the last time we had that much snow was 10 years ago tomorrow, when a storm dumped 22.4 inches in the city and over 30 inches northwest. While this storm is structured a bit differently, it is looking more and more likely that parts of our area will be in the bullseye zone of 12-16-plus inches. The exact track will determine that.
- The last time Philadelphia saw a 6-plus inches snowfall was 7.5 inches on Jan. 29, 2022
- The last time Philadelphia saw a 12-plus inches snowfall was 22.4 inches on Jan. 23, 2016
- The last time Philadelphia saw more than 24-plus inches of snow was 28.5 inches on Feb. 5 and 6, 2010
NEXT big weather change
Snow will begin to overspread the area between midnight and 8 a.m. Sunday morning — it will likely be snowing at least lightly by the time most of the area wakes up and starts the day. Snow will fall at least moderately through midday, but will ramp up in intensity through the afternoon and into Sunday night as a coastal low develops offshore.
The snow will start out light and fluffy with cold air in place, but as the low deepens offshore, it will draw in warmer and moisture-rich air. This will lead to heavier snowfall rates with banding - rates may exceed 1-2" per hour - but will also mean a heavier, wetter snow and even the potential for some sleet or freezing rain, especially to the southeast.
The mixing threat is currently the biggest wild card because any sleet could cut snowfall totals, but where the precipitation stays all snow, it will pile up quickly. We have issued a first call snowfall map and will continue to refine exactly where the contours will set up, and determine where the most likely "bullseye" zone will be. Philadelphia right now is in a general 8-14 inches zone with 6-12 inches just to the southeast and 10-16 inches just northeast.
Impacts include power outages, airport cancellations, train delays, dangerous roads and downed trees.
School delays and closings are highly likely on Monday, Jan. 26.
Temperatures will plummet Monday through the middle of next week, with highs in the low 20s and overnight lows dipping to single digits and below zero. So, plan on this snow sticking around through the end of the month.
The best advice is to stay with the NEXT Weather team for frequent updates each day to plan and prepare for the weekend. Have the shovels and ice melt ready. This could be the biggest snow of the season.
