The 95 corridor did not get warned.  Harford, Northern Baltimore, Carroll, Frederick, and Loudon did, but Carroll, Frederick and Loudon got dropped at the 11PM update and, interestingly, did not even go to an advisory.  Southern Baltimore, Howard, Montgomery, Prince Georges, and AA were all advised, and I think DC eventually got one too.

Thats a bust as far as I am concerned, especially when counties south of Baltimore got Advisory to maybe even warning criteria snow totals and they had no advisory going in.  They do a great job... but I have to be critical.  I know a lot of people who were out on the roads last night who may not have been if they did a better job.  But we all basically busted.  No-one thought this would over-perform.

DCA had 1.9" at midnight.  Please tell me they got 0.1" by the fluff after midnight...

 

Somewhere between 5 and 6" here, I'll wait for the final spotter reports before calling it.  Warning criteria.  Hard to believe! 

 

BWI just as bad. 3.6" is way low. I'm 3 miles south and got 5.5", which lines up with most of the other obs around the airport.

DCA 1.9" storm total per CWG tweet.

http://www.ncdc.noaa.gov/wdc/metar/index.php?name=handbook-toc-coding Table 12-6. Units of Measure of Precipitatiom Type of Measurement Unit of Measure Liquid Precipitation 0.01 inch Water Equivalent of Solid Precipitation 0.01 inch Solid Precipitation 0.1 inch Snow Depth 1.0 inch

 

They round to the nearest inch I believe.
