Sunday May 19 Morning Report The aftermath of the rainy Saturday is plenty of leftover moisture. This has left us with a bit of humidity and areas of thick fog…

8 AM Friday Morning Update
We are tracking the freezing line and transition to brief snow across the region. This is holding pretty close to the schedule, maybe just 30 to 60 minutes slower than my timeline. The rain, perhaps sleet and brief snow is intense along the front. This is NOT The Day After Tomorrow, but it might feel like it. The temperatures and wind forecast maps below tell the story of how fast and hard the temps will drop and the wind will pick up. We have had conditions like this before, but it is rare. It will hurt to be outside and I hope you avoid driving during the transition.
Rain has been falling and is still moderate to heavy in spots ahead of the front. 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. My new Profile Timeline maps for areas highways are below to assist.
Radar And Temperatures at 8 AM
Low resolution look at the radar and approaching freezing line.
Doppler Radar High Resolution at 8 AM
I was given the quote, “It’s Crazy Here”! – From Eldersburg. This is an intense squall line, and justifies school closings, regardless of the freeze.
More Local Weather Stations At 8 AM
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 to 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.
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.
