CBS3: 5+" Philly and local burbs
FOX29: 6-10" Philly and local burbs
When I say local burbs it's only up to mid Mont/Bucks county. (sharp cut off) Further out burbs 3-6"
Oddly enough Ch10 going w/the same 6-9". First off 6-9" is not a normal range and Ch6 and Ch10 usually don't have the same exact amounts..kinda strange.
It could happen???
The National Weather Service defines a blizzard as a storm with large amounts of snow or blowing snow, winds greater than 35 mph (56 kph), and visibility of less than ¼ mile (0.4 km) for at least three hours.
If you're thinking 4-6" is a good total and the duration is 36+hrs....that's like light snow/heavy flurries? Or are you thinking sleet...breaks in action etc?
I witness both real time....and still sane.
Some DC folks are currently jumping ship or whining because their totals are cut in half but still solid.....they picked the wrong "hobby"..
