Snow Report Saturday March 12 2022

The following are maps and list of reports from snow spotters to the National Weather Service. There are gaps and perhaps numbers that don’t match what you had by you, but this the best we have at this time.

There was a big jump from a slushy trace along many water locations, Metro locations between 1 to 3 inches, then higher amounts farther inland. The big winners locally were where the Winter Storm Warning was expanded this morning. This is where over 4 inches of snow fell in Northern Baltimore County, Carroll, Frederick, and westward.

Elevation and proximity away from the water played a big role in snowfall.  Here was can see just a little inland from the Bay and snowfall amounts jumped.

First the maps, then the list of individual reports…

 

 

 

Baltimore’s Official Report

Baltimore’s BWI reported a total precipitation of 0.69”.

But adding up the hourly reports with snow since 8:28 AM = 0.32”. Under normal condition that would have translated to 3 inches of snow.  But due to melting, only 0.4” snow was reported at the airport. A lot of snow fell and melted on the warmer ground.

Compare that to Elkridge just a couple of miles away and the snow report was 2.3”.  That has been the case much of this winter… making many wonder if BWI Airport is an artificially warmed location, or simply just luck of the geographical draw?

Just inland across much of Howard and Montgomery Counties there was a wide range of 1 to 4 inches of snowfall.

 

Central Maryland:

 

 

Closer Look At Metro Baltimore

 

Western Maryland

Most of the mountainous region got over 4 inches. However there was a lower (expected) range around 1 inch or so, that included the Cumberland Valley.

 

 

 

Southern Pennsylvania 

An average of 3 to 5 inches in the region.

*Disclaimer due to frequent questions:

I am aware there are some spelling and grammar typos. I have made a few public statements over the years, but if you are new here you may have missed it:

I have dyslexia, and found out at my second year at Cornell.  I didn’t stop me from getting my meteorology degree, and being first to get the AMS CBM in the Baltimore/Washington region. 

I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse. 

All of the maps and information are accurate. The ‘wordy’ stuff can get sticky. 

There is no editor that can check my work when I need it and have it ready to send out in a newsworthy timeline. 

I accept this and perhaps proves what you read is really from me…

It’s part of my charm.
