Philadelphia Winter Storm Alert: 12-18 Inches of Snow Expected! | Bomb Cyclone Update & Prep Tips (2026)

Hold onto your hats, Philadelphia and the Jersey Shore—a monster winter storm is barreling your way, and it's not playing around. This could be one of the most intense snowstorms in recent memory, with the potential to dump a staggering 12 to 18 inches of snow on the city and even more along the coast. But here's where it gets controversial: meteorologists are calling this a possible 'bomb cyclone,' a term that might sound like something out of a sci-fi movie but is actually a real—and rare—weather phenomenon. So, what does this mean for you? Let's break it down.

Updated by Andrew Kozak, Bill Kelly, and Tammie Souza on February 22, 2026, at 7:36 AM EST for CBS Philadelphia, this storm is shaping up to be a doozy. Blizzard and winter storm warnings are in full effect as a coastal nor'easter takes aim at the region, starting Sunday afternoon and intensifying into Monday. The NEXT Weather team has been tracking this system all week, and while models initially disagreed on its path, it now appears the storm will hug the coastline, bringing heavier snowfall to inland areas. This is the part most people miss: even though temperatures will hover above freezing for much of the day, the storm's dynamics will override the warmth, ensuring the snow sticks.

But here's the kicker: this storm could rapidly intensify as it 'bombs out' southeast of Delaware, earning it the nickname 'winter hurricane.' Winds will howl, snow will fall at a rate of up to 2 inches per hour, and travel conditions will deteriorate rapidly. Officials are urging everyone to stay home Sunday night, as whiteout conditions could make roads nearly impassable by 5 PM. Power outages are also a real threat, thanks to the heavy snow and high winds.

If you must venture out, do so early. Roads will be slippery in the morning but will become treacherous by evening. And don't forget to prepare: charge your devices, stock up on pet supplies, and get ready for potential school closures and virtual learning. For drivers, fuel up your cars, check your tires, and pack an emergency travel kit. Oh, and don't forget to have your snow blower, shovel, and ice melt at the ready.

Here's the timeline you need to know: The storm kicks off Sunday morning with spotty rain showers and temperatures in the mid-30s, melting any early snow. By Sunday afternoon, rain will dominate along I-95 south and east, while slushy snow showers move in north and west. Come Sunday evening, temperatures will drop into the low 30s, and the rain will transition to all snow by 8 PM. The heaviest snowfall hits between 9 PM Sunday and 6 AM Monday, with the storm pulling away rapidly by midday Monday.

But wait, there's more: A blizzard warning goes into effect at 10 AM Sunday through 6 PM Monday for coastal counties, Delaware, and parts of southeastern Pennsylvania. A winter storm warning is in place for Philadelphia and surrounding counties from 5 AM Sunday to 6 PM Monday. The Lehigh Valley, Berks County, and the Poconos are under a winter storm watch during the same period. And for those along the Jersey Shore, a coastal flood watch is in effect from 9 PM Sunday to 5 PM Monday, as northeast winds could push water inland during high tide, causing moderate flooding.

Now, let's talk snow totals: Philadelphia and areas near the I-95 corridor can expect 12 to 18 inches, while the Lehigh Valley will see 8 to 12 inches. The real winners—or losers, depending on how you look at it—are the coastal areas, where 14 to 22 inches or more are possible. The highest totals will be at the Shore, with the lowest in the Lehigh Valley.

Here's your 7-day forecast:
- Sunday (NEXT Weather Alert): Winter storm. High 39, Low 35.
- Monday (NEXT Weather Alert): Snow clears. High 38, Low 31.
- Tuesday: Mostly sunny, cold. High 33, Low 25.
- Wednesday: Quick snow, rain shower. High 43, Low 25.
- Thursday: Chance of rain. High 46, Low 34.
- Friday: Few showers. High 43, Low 31.
- Saturday: Sun returns. High 52, Low 27.
