[Update 7:55 am] Philly public schools will close at 12:30 pm today, due to the storm.
Between 8am-11am: Snow slowly arrives from west to east. (The morning rush should scrape by without any major issue.)
Late morning to early afternoon: Light snow overspreads the region.
Mid-afternoon to evening: Heaviest snow will fall, with snow rates of 1” an hour at times.
The highest accumulations are expected in South Jersey and Delaware. The evening drive will feature poor visibility, slow/slick travel, and snow-covered roads.
The snow should end by 4 a.m.
The storm is expected to drop 9 to 14 inches in the Philadelphia area and even more at the Jersey Shore and in parts of Delaware.
"It's a major snow storm," said NBC10 First Alert Weather Chief Meteorologist Glenn Schwartz. "Many areas are expected to get over 6 inches, plus wind, plus cold. The worst of this storm will be late Tuesday and Tuesday night."
The aftermath will also be brutal, John Bolaris says:
A weak storm will move into the Tennessee Valley Tuesday morning, marking the leading edge of the arctic outbreak. As that one weakens, another storm develops and intensifies rapidly off the Virginia coast, spreading snow, heavy at times with increasing wind and falling temperatures. Temperatures by Wednesday morning will be in the single numbers with wind chills 10-15 below zero. Plenty of blowing and drifting of snow. Dangerous cold.
Be careful out there.
