It has been since 2009 that Baltimore saw snow on Dec. 5, and more is not expected Wednesday, extending a reversal in a snowy pattern that dates back to at least 2002.
The date, out of all in December, is the one on which it most frequently snows at least an inch in Baltimore. (Some days in January and February see more frequent snowfall.)
From 2002 through 2009, it snowed six out of eight years' Dec. 5. Dating back to 1892, when snow record-keeping began, it has snowed nine times in Dec. 5 in Baltimore. That's all according to this post by Frank Roylance from 2010 on the curious snow pattern.
But 2009 was the last to see snow on Dec. 5. It was cold, in the 30s all day, but dry in 2010. Last year, it was dry and mild, with highs in the upper 50s, and the forecast is the same for Wednesday.
Jan. 7 is the most frequently snowy day in Baltimore, with 13 snowfalls since 1892. We haven't seen measurable snow on that date since 2010, and then it was only a tenth of an inch.
Jan. 28 there have been 11 snowfalls of at least an inch, while several days in January and February have tallied 10 snow days.
