11 AM Friday Morning Update
Around 9 AM I did a live report on Facebook as we tracked the development of Low Pressure along the front. That is why there was an expectation for some additional snow. Only a dusting to an inch at most, for 30 minutes to 2 hours. What also occurred was the squall line that had sleet and thunder as it passed metro Baltimore. Wild stuff! Now we get into the deep freeze and dangerous wind chill.
I will post that Facebook Video below (if you want to see old news). The focus now is a roundup of weather conditions around 11 AM and a recap of the forecast.
Interesting Observations
After speaking with a few of my clients, they noted they saw ice on their trucks BEFORE temps dropped below freezing. The cold air AND strong winds led to evaporative cooling on the metal and rubber of their trucks. The result was the surface was colder than the air and allowed for icing. So, the dampness from the roads kicked up on their trucks and iced over.
Also: Salt will let the ground stay wet into the 20s. Depending on whether it’s brine or a Magnesium Chloride mix will allow it to stay wet into the teens or single digits. This allows time for the wind to dry out the pavement.
If anything is still wet by this evening, it will freeze! However, most roads will be dry. I caution for sidewalks and steps on the wind-protected side of your property (facing east). This may not dry out and ice over.
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.
The ground is soggy and temps 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. Just wait it out a bit and you will be fine to travel this afternoon. Just very cold!

Wind Chill Advisory: Dropping to -20ºF this afternoon into Saturday morning.
Wind Advisory and High Wind Warning
Most of the region will experience wind gusts between 40 and 50 mph, while up to 70 mph in the mountains.
Source Of Arctic Air
This has extended to 10s to Dallas and Houston, TX and Atlanta, GA. Below Zero in St. Louis, Columbus, and Chicago!
Below Zero from Chicago and westward! This is all racing our way to the East!
Morning Surface Weather
Forecast 10 AM – (Verified Pretty Close)
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.
