February 9th – Did you get the snow you expected? If you live west and north of Baltimore the likely yes. If you live in the city, near the Bay, or south, then likely not. If you are new to my forecasting blog, then hopefully now you know why I wait until 48 hours before an event to give my first call. The high numbers tossed around for days might have described the full potential of the system, but fine tuning for your location that may have received less is what I prefer to do to limit disappointment or over hype. Even though some areas get even less than my low end.
I am writing this on Tuesday evening while there is still some light snow left with this system. But I wanted to share the snow spotter reports from The National Weather Service for central Maryland and southern Pennsylvania and compare them to my forecast. The north side worked out well, as it often does. It was ironic that schools were open on time in York County where the most snow fell, but much of central Maryland had their schools closed. I must ask the question: If the forecast is for snow and it snows, but is just a little too warm to stick, is it a complete bust? I know there was rain around Annapolis and Washington that was a bust, even with my late adjustment mentioning that. So after seeing these numbers and comparing to my forecast map, please share your thoughts with me and even give me a grade.
Please see notes below and the complete spotter list for the region at the bottom of this post.
- Baltimore’s BWI recorded 0.4″ of snow. The liquid precipitation measured 0.35″ which in normal conditions would have produced 3.5″ of snow. The amount was justified, but it was just a little too warm to stick.
- Notice the drop off around I-95 and south. That was the warming influence from the Chesapeake Bay.
- Higher totals inland ranged from 2″ to 6″ with elevation playing a roll (colder hilltops). This covered my 3″ to 6″ range and even the higher 5″+ bullseye well north.
- Northern Harford and Baltimore County reports from my spotters averaged 4″ to 6″, higher than the NWS reports.
- My bust was I-95 and south where snow melted or was just rain.
- The onset was a few hours late, which did not allow the cold to take home before sunrise. That was my main fault
This is a region that I often get the right call for as location away from the water and elevation helped to hold the cold.
- Many reports in York County on my Facebook Page ranged from 5.5″ to 7.5″. Higher than the spotty spotter reports listed here.
- Hanover shading doesn’t fit the 5″+ reported by a few people there.
- It reached max snow before noon, but snowed all day. There was melting and compacting that compressed the snowpack during the afternoon.
How did I do?
Here is the regional snow spotter map. Again, this is not perfect, but the best offered from NWS. Compare to my last call for snowfall… The ‘edited’ version only annotated where my forecast was working out and not. I posted that during the morning to hopefully update you in time. Please comment and even grade my forecast on the social media post you saw this article.
I welcome your comments, but must say that even if you did not get snow sticking, it was not a complete bust. It snowed for most that expected it (except Annapolis). Not sticking was only part of the forecast.. and it actually did pile up as expected for at least half of the region. That might not matter if your house is not located there, but it’s worth considering.
My Grade For Myself: B-
Agree or not? I’d like to hear why…
