A major storm is expected Bring lots of snow to the Philadelphia area over the weekend, this will probably affect your plans.
The worst of the storm is forecast along the Jersey Shore and Delaware beaches, but the entire area could see snow. Depending on where you live, this storm could change or completely ruin your Saturday plans.
Below, we answer five big questions about this weekend’s weather.
How much snow is expected and when will it fall?
Some places dealt with light, sporadic sleet Friday morning, but things will start to get stronger Friday night and continue through Saturday afternoon.
The worst of the snow is expected Saturday morning, but it could last longer if the storm arrives more slowly and closer to the coast.
The northern neighborhoods are expected to see the least amount of snow, while the Jersey Shore and Delaware beaches are likely to have the most snow this time around. There are also blizzard warnings for the Jersey Shore and Delaware beaches.
Here’s a regional breakdown of the estimates as of Friday afternoon:
- Far north and western suburbs of Pennsylvania, Berks County, Lehigh Valley: 2 to 4 inches
- Chester County and Bucks and Montgomery Upper Counties: 4 to 7 inches
- Philadelphia, Trenton, Wilmington, nearby suburbs, inland South Jersey and central Delaware: 7 to 11 inches
- Jersey Shore, Delaware Shore and easternmost New Jersey and Delaware spots: 12 to 18+ inches
Slight shifts in the storm’s east or west track can still affect total snowfall.
Should I cancel my Saturday plans?
Your Saturday plans may be safe if you head further north, but you’ll probably want to cancel your plans further south.
“It depends on where you are. So I would say Lehigh Valley and Berks County, I would delay your plans if possible, but if you really need to go, you can. Philadelphia and surrounding suburbs come ashore, yes, cancel your plans or postpone them,” said Steve Sosna, NBC10’s First Alert Meteorologist.
Is this a sled and a snowman?
This snow is sure to be great for skiing. You’ll probably have a hard time making the snowman, though, because the snow will be very powdery and won’t stick together well, says Sosna.
How does a blizzard affect driving and walking in the snow?
In Sussex County in Delaware, and Atlantic counties, Cape May, Oceania and coastal Burlington in New Jersey, blizzard warnings are in effect, meaning people should prepare for the worst.
The National Weather Service defines a blizzard as a storm with large amounts of snow or strong snow, winds greater than 35 mph, and visibility below ¼ mile for at least three hours. Wind gusts on Saturday are expected to reach 50 mph.
So, basically, a blizzard is a strong snowstorm with low visibility.
“Snowstorms are very dangerous because visibility often drops to close to zero. So you can’t see in front of you, which means you can get stuck really easily if you’re traveling,” says Sosna.
Technically, snow doesn’t have to fall either; Strong winds can sweep snow that has already fallen off the ground and whip it around in the air, thus causing a blizzard.
Since the blizzard winds are so strong, that means that even if the teams manage to clear the roads, more snow will still be blown back, Sosna said. This makes the roads almost impossible to clear.
You also don’t have to be safe if you think you might drop your car and walk through a blizzard.
“From the perspective of a human walking around, you’re dealing in this case with really, really cold temperatures. So frostbite can happen, and that’s a real problem if just making it hard on the body,” says Sosna.
What is bombogenesis and how does it affect this storm?
You may have heard the term “bombogenesis” used a lot these days.
It’s a common word among meteorologists, according to National Oceanic and Atmospheric Administration, which describes the process that occurs when a tornado in the middle rapidly strengthens, dropping at least 24 millibars in 24 hours. The millibar is a unit of barometric pressure.
According to NOAA, the process of bombogenesis creates what is known as a bomb cyclone — yes, that’s a real scientific term.
So what does this scientific jargon mean in layman’s terms?
With cold weather hitting much of the country, here are some tips to keep your furry little ones safe and happy this winter.
“What happens is the bands of snow become denser, so you get a higher percentage of snowfall. So even though the storm is a fast-moving storm, you can still get a lot of snow due to the intensity of the snow, and you get that from the bomb generation,” Sosna said.
