October Nor’easter Snow Totals

A snow producing storm in October is rare. In Baltimore, measurable snow has been recorded only three times since the late 1800s … 1925 – 1940 – 1979.

This most recent storm produced only a trace (officially not measurable) of  snow at BWI-Marshall. This ties the “record” for October 29 that was set in 1952.

The nor’easter did produce significant, wet, heavy snowfall elswhere in the Mid Atlantic region. Below is a map with a sampling of snow totals in Maryland reported as of 10:00pm, October 29. (Added Sunday morning … A Sunday morning satellite image of the swath of snow laid down by the storm follows the snow totals map.) (Added early Monday….a false color, high resolution satellite image of the snow covered areas.)

The visible satellite images below clearly shows the snow laid down by the nor’easter. The Susquehannah and Hudson River valleys are easily identifiable in the snowpack. The false color, high resolution satellite image shows spectacular detail of the storm’s snow track. The color image was captured Sunday by NASA’s MODIS polar orbiting satellite. The black and white image was captured from the higher orbiting NOAA GOES satellite.  Maryland and regional snow totals are listed below the images.
