December 19 2022

Monday Morning Update 

Today is the anniversary of the largest December winter storm in our region. Baltimore received 17 inches of snow on this date in 2009, with lightning early in the morning. I recall seeing that on my way to work!  That kicked off our largest winter snowfall total (77 inches), which included 2 blizzards in 5 days in February 2010.

This winter has another storm, but it’s kicking off differently! The latest round of cold air gets reinforcements with gusty winds today. It will feel up to 10 degrees colder as a result.  The weather will otherwise be quiet for a few days, then we track the winter storm arriving Thursday.

The quick glance for that winter storm is below. It looks like maybe a brief start with a mix, then rain ending with brief snow and flash freeze Friday. Christmas weekend will be frigid! Perhaps the coldest in a decade or so. 

 

Morning Temperatures

The cold air in place is seasonal, but colder winds will hold the temps down this afternoon.

Headlines

  • Today: Cold, Windy, But Dry
  • The Storm: Thursday morning to Friday.
  • Christmas Weekend: VERY COLD

 

Morning Surface Weather

I am showing this wider view to highlight another feature influencing our storm.

The one reason I see the storm ahead NOT being that coastal snow maker: Newfoundland! That 50 Lat/50Lon location is where the last storm was expected to close off and stall. That would have held colder air in place longer AND prevented the next storm from closing off… to shift to the coast. 

It is now expected to keep moving into the Atlantic, so the next storm gets stronger, closing off to the west and pushing warmer air up the coast instead.

In the meantime, High Pressure will build in for a few quiet days for us.

Looking Ahead To The BIG STORM (2-Days)

Computer Model Guidance From Sunday Night

Thursday Morning 

The ECMWF Model does have that wintry mix, west of the mountains. I continue to be skeptical of a few model plots based off of recent bias.  If this arrives earlier (like other events), then a brief start with wintry mix may shift east.December 19 weather snow storm start Thursday morning

 

Thursday Afternoon

The later start on this models allows for some warming and rain in the cities.

The major snow impact will be in the Mid-west where blizzard conditions are likely to expand to the Great Lakes. This may have a ripple effect for plane travel around the country ahead of Christmas.

7 AM Thu to 7 AM Sat

The evolution of the storm on this model has been consistent with a warming rain into Thursday night and Friday morning, then ending with a brief period of snow and flash freeze.

Again, any shift in speed and timing could expand the snow and icing risk. Still more to sort out and today will help fine tune that for us.

Key Timeframes Friday

1 PM – Friday Afternoon 

Surface Weather Forecast

The cold front location is the make or break of the snow or ice impact. It may snow with temps just above freezing, then the thermometer will crash. It will be a matter of if roads are wet when the deep freeze arrives. 

December 19 winter storm freeze Friday

 

Closer View

This shows the timing of the cold from to reach New Jersey by 1 PM. Colder air will be flowing in behind. The debate is how much moisture will be left over as the cold air arrives with the deep freeze.

Wind Flow

The arctic front will kick up very strong winds for a few days.

Winter Solstice is Wednesday!

Thursday and Friday remain a WILD CARD. The information the models put out this morning will help us refine expectations. If there is any shift/flip or locking in on the the timing, we may see it today.
