Baltimore Snow History: Breaking Pattern Of Storms

Baltimore Snow History: Breaking Pattern Of Storms

With the impending blizzard of 2016 tagged to hit January 22 to 24, I wanted to focus on Baltimore snow history to show how epic this event should be. I have an obsession with snow and I’m a statistics guy. That’s a great combination and encouragement for STEM educators. I’ve compiled the records of major snowstorms plus annual snowfalls. This includes some regional impact storms.  The Blizzard of 2016 will break a pattern for us, or is it starting a new one with more frequent events? Perhaps it is repeating a pattern that was set 50 years ago?  FITF There have been estimates that a top storm today could cost of $1 Billion.  Below are some of those stats and charts for you to compare as the blizzard bears down on the entire region, not just Baltimore. But based on Baltimore and patterns, an example was our December 5th date with destiny, the date of our first snow almost every year for a decade. There are other patterns recently and over longer periods of time. Check it out and Faith in the Flakes.

Big Snowstorms 3_4YrsWe’ve also had a pattern of large snowstorms every 3 to 4 years in Baltimore dating back to the early 1990s. That includes events nearly a foot (11.5″ or more). The triple blizzards of 2009-2010 fit that, but also broke it with three events in one season.  Our last one was around Valentine’s Day in 2014. That was two years ago, and the reason why I did not expect a major event this season. Well, I was wrong about that.  This storm will surely break out pattern, and give Baltimore 5 major storms in the past 6 years.

Note: The blizzard of Feb 2010 was on the way to the top all time storm… but right before it ended, The National Weather Service changed it. They said the snow measuring procedure by the FAA at BWI (measuring every hour then wiping the board clean) was not accurate compared to NOAA guidelines of measuring every 3 hours and allowing for weight and compression. They went back and lowered snow totals, including the December 2009 event and prior. 

Depending of your visual preference, I’ve compiled this same in a chart below.




Baltimore To Snowstorms

We need to pile up 19.5 inches of snow to break into the top 10 on record (note all time is poor wording since we only have records dating back to the 1870s)

I made this list a few years ago to show that almost half of our major snowstorm have come in the month of February. Often around Presidents Week.  This breaks that trend as well.

Here are the top 2 storms for our region based on size, population impacted, snowfall, and dollar cost. The estimate for a top storm today is over $1 Billion




Baltimore Snowfall By Decade


You want to talk extreme weather? Look at the least snowy decade of the 1950s. That was followed by the most snowy decade in the 1960s. Looking at these decades is one reason why I suggested that we were in a upward snow trend after the relative drought. But we have had some of our largest snowstorms in the past decade.
