1968
After starting last night at around 9:00, heavy rain continued thru this morning. By the time it ended, shortly before 11AM, 4.88" had flooded the City, snarling the Wednesday morning commute. The 3.99" that fell today set the daily record for the month of May (breaking the previous record of 3.82" on May 9, 1908).
1969
Today was not only the first 90-degree of the year but, with a high of 97°, it was also the hottest reading all year (there would be highs of 96° on June 28 and July 17).
1990
Beginning at 8AM and continuing for the rest of the day, 2.40" of rain fell. This was a little less than two weeks after 2.32" fell, and brought the month's rainfall up to nine inches. Today's heavy rain kept the temperature well below average as the high was only 60°, fourteen degrees below average.
1995
During a severe nighttime thunderstorm on Memorial Day, 0.50" of rain fell in just 30 minutes (9:40-10:10 PM). The storm was also accompanied by hail.
1999
Memorial Day weekend began today and all three days were marked by sunny skies and high temperatures in the upper 80s (87-88-89).
2001
Including today's 0.18" of rain, all but 0.07" of the month's 2.03" rainfall came in the past nine days (the first seventeen days of the month had no rain).
2006
Today was Memorial Day, and for the first time since 1999 the temperature rose into the 80s. The afternoon high of 88° was fourteen degrees above average.
2012
Under sunny skies chances appeared very good that the year's first 90-degree reading would happen today. Alas, we came up short by one degree, mirroring yesterday's high of 89°. However, very high humidity (the dew point was in the low 70s) pushed the heat index into the mid-90s.
2016
Today was the fifth day in a row with a high temperature of 87° or warmer and a mean temperature that was ten degrees or more above average (two days were in the 90s). Temperatures during this five-day period were 14 degrees above average.
2017
Overcast skies and light rain from 5AM until noon kept temperatures stuck in the upper 50s for much of the day (the official high, 61°, occurred in the hours after midnight). This was the chilliest Memorial Day since 2003, when the high was 56°.
2017 was actually the chilliest Memorial Day since 2003, when the high was 55°. at least i think this is true.

Hi William,
Yes, the year is 2003 not 2004 - thanks for catching it. Regarding the high temperature, the source I use for all temperature data is the monthly Local Climatological Data report published by NOAA/Nat'l Climatic Data Center. It reports that the high on Memorial Day in 2003 (May 26) was 56 degrees.
