January 5 2018

The storm that rolled up the coast on Thursday January 4 was the media’s exposure to a classic meteorological boom. The pressure level dropped even more than the definition of 24 millibars 24 hours. NOAA measured a pressure drop of 59 millibars in 24 hours, making this the most rapid intensification in the western Atlantic since 1976. The lowest central pressure was 950 mb.

Winds gusted over 50 mph along the coast, and this was a well defined blizzard for many locations. That includes out coastal Maryland and Delaware where nearly a foot of snow fell and snow drifts pushed over 3 feet. See photos below.

Baltimore’s BWI measured 0.9″ of snow. Just under my initial call, but the blowing wind pushed it all around anyway. Schools were closed and that is the criteria many students and teachers will base my grade on.

Salisbury got 12.5″ and Ocean City measured 11″.

The back edge of any stickage was near Frederick, and the tight gradient of totals was just a little east. The heaviest amounts in Southern Delmarva and Southern Maryland did fall in line with my call. But Cecil and Kent Counties in Maryland were in the lower end and may feel slighted.

Here is a comparison of my forecast map to the snowfall totals confirmed by NOAA. This was not an easy call since it was such a large storm and we were on the edge. I was torn between my Atmospheric Memory of tropical system staying well east and the trend of recent systems staying closer. Overall, I am happy with my call. There were computer models that went much higher with totals, but I stayed the course and it worked out well for most areas. Please check it out and let me know what you think. I grade myself an A- as the timing and general regional call worked out well. The slightly lower metro numbers are within the margin of error for my comfort zone.

My Final Call For Snowfall Map

  • A: Dusting to 2 Inches
  • B: 2 to 4 Inches
  • C: 3 to 6 inches
  • D: 6 to 12 inches

Satellite Loop

This 14 hour look of the new GOES 16 Satellite is simply amazing. Watch the intensity of the core Low off of the Mid Atlantic coast and what appears to be an eye. This is not a tropical system, but does have a warm core trapped in the middle of colder air. The contrast is what made this so impressive.

I see these for fun, but also:

Faith in DE Flakes

I survived the Blizzard of 2018- Special Edition shirt for Delaware. Sussex County was the big snow winner. See the snow measurements below.
