IN PRINT TODAY, MAY 9, 2010 - The last traces of February’s snowstorms – remnants of huge piles dozed from parking lots - have finally melted away. But even in May snow is not impossible here. On this date in 1923 Baltimore recorded a trace. The latest on record for the city fell May 11, 1951, also a trace. Anyone remember that? But we should be snow-free at least until October. The earliest measurable snowfall here was 0.3 inch, on Oct. 10, 1979. Orioles fans will recall that one.
