Friday Morning Update
Today is storm day and we will get validation from this impressive monster storm. You can focus on Bomb Cyclone, Arctic Front Flash Freeze, High Winds, or Dangerous Wind Chills. They all fit and will happen in a hurry!
Rain has been falling and still moderate to heavy in spots ahead of the front. The ground is soggy and temp will drop 20 degrees in a matter of 1 to 2 hours. Add in some snow, even if minimal, and that is the concern to allow moisture around to freeze “in a flash”. I truly advise not being on the roads when this transition happens. My new Profile Timeline maps for areas highways are below to assist.
I want to highlight that the snow part will be minimal, but could impact just enough. New Advisories have been issued in Pennsylvania where snow squalls are possible and will accumulate a little more, adding the the road issues.
Caution: I would just avoid travel this morning, so you don’t risk getting stuck in traffic. It will be painfully cold this afternoon, but roads will be passable.
If you are traveling for the holiday, take a cold kit in your car (blanket, extra clothing, food, and water), just in case you get in long traffic lines while in the deep freeze.

Source Of Arctic Air
This has extended to 20s to Houston, TX and Atlanta, GA. Single digits in Memphis!
Below Zero from Chicago and westward! This is all racing our way to the East!
Morning Surface Weather
Tracking the Cold Front… This is rapidly changing and I intend to have an update on this map around 8 AM.
Forecast 10 AM
The Bomb Cyclone will have rapidly dropping pressure. That is the wind machine that will be responsible for this mess.
New Low Pressure is expected to form along the arctic front. That is the element that will make or break how much snow will fall. If it forms, we get more snow. If it is slower to spin up, then less snow for us.
Radar Simulation
HRRR Model: 6 AM to 1 PM
This is a quick hit! Reminder: The amount of snow will depend on Low Pressure forming along the front.
Most likely a dusting to 1 inch in central Maryland, a little more in southern PA.
