Thursday December 19 2019
Happy Anniversary! It was 10 years ago today that we set a record in Baltimore at BWI. Initially 20.5″ of snow fell, but The National Weather Service (NWS) lowered the daily total to 17 inches, which is still a record and the most for any date in December. It was the first of three blizzards that winter, but also one of a few events NWS retroactively lowered totals. This was a point of contention not only with weather geeks like me, but how much federal dollars were allocated with the emergency that followed with clean up.
I remember doing special coverage on TV for that storm and saw multiple flashes of lightning and the dampened rumble of thunder in heavy snow at 3 AM in Towson. At points the snow was falling between 2 and 3 inches per hour. Winds did exceed 35 mph verifying this as a blizzard. What do you remember about that event?
The flurries yesterday and evening snow squall signaled the arctic air spilling in, and it is definitely here this morning. Temps have dropped and will struggle all day as most of the region will remain below freezing. Add in wind gusts to 30 mph and the wind chills are in the single digits for many kids at the bus stop. I think recess will be inside today.
Dress in your warmest clothing today. Winds will ease but we remain cold this afternoon. Then we set up a quiet pattern for the next week. This will allow temps to reach the lower 50s on Christmas. There will be some rain or snow returning before New Year’s, but we get a breather for a week.

Polar Vortex Locked Up
Jet Stream 500mb Heights Around The Northern Hemisphere
This is a view looking down on the North Pole (in the center). The Polar Vortex appears to remain contained for the next week to 10 days. This is good for regeneration of arctic ice, but also growing the cold. I expect this will get dislodged in January and unleash bitter cold and feed an active storm pattern by the middle of next month.
