Recapping the first storm of the season, and biggest event in two years, Many places got more snow than all of last winter! I have lots I want to share with you and document here for reference.
As always, I want you to grade my forecast. This time added a poll below to tally as many as possible in one place.
In this report you will see:
- Regional Snow Map And Satellite
- Time Lapse Snowfall Video – My first complete storm!
- Grade My Forecast Poll
- Local Snow Reports and Compare with my Final Call For Snowfall
I started discussing this storm last Thursday, and it got a lot of attention. I believe it deserved it for the region. I will highlight what I think worked out and what went wrong.
I know some will say this was a bust. That always happens. Some will say it was perfect. But the reality in between is where I am interested. I do this service for you and value your trust.
Binghamton NY was a big winner with 41” inches of snow. I worked there at WBNG TV before moving to Baltimore in 1997. They know snow, but that was a record!
They also recorded:
6” in one hour
20.5” in a 6 hour span.
*There were other 40 inch reports into southern Vermont.
Satellite This Morning
This storm was so intense, we can see what appears to be an eye on satellite south of New England. This is somewhat common with the strongest winter storm. I have a closer look at our region below.
Time Lapse Video
I want to start with my very first complete storm Time Lapse Video
- We had two rounds of snow with sleet in between that compressed totals a little.
At one point nearly 3 inches fell in one hour.
The second surge was between midnight and 2 PM
Final total zoomed in at the end: Between 10 to 11 inches (around the MD/PA line)
Snow Line From Space
This close up of the visible satellite this morning showed the snow line lined up very close to I-95.
Why does this happen? Because I-95 was built on the Fall Line. North and. West the elevation increases, it is farther away from the warmer Chesapeake Bay, and colder.
See County maps and spotter reports below.
My Final Call For Snowfall.
Use this map to compare to results below.
What Went Right:
- Sleet, icing, and Rain were on target.
- Most of my zones worked out: 6″ to 10″; 3″ to 6″, and even the Coasting to 3″
- Thursday morning temps in the 20s starting the day icy for many!
- My First Call and Final Call were almost the same. I did shave off the south end.
- I played it conservative: My call was LOWER than NWS, Most Models, and many local TV offices.
- Snow zones: Mostly Right, but we can compare to my forecast below.
What went wrong:
- The arrival was almost 2 hours earlier than I expected.
- The front end overachieved for many, but the back end was lower.
- A little under 10” in many of my 10″+ zones
My Personal Grade: B+

Harrisburg set a daily record for snow and had more than all of last year.
Most of this region was in my 10″+ zone, but ended up mostly 6 to 10 inches.
