March 15 PM Update: More record reports:

Boston blew away its record for March 14 with 3.40", far exceeding the 1.93" in 1958. This was also only slightly below the all-time March daily record rainfall of 3.49" on March 18, 1968, making it the second wettest March day in Boston history. The last time a 3" calendar day rainfall occurred in Boston was on May 13 and 14, 2006.

Worcester's 1.75" broke the March 14 record of 1.39" in 1986.

Portland, Maine had 2.27", breaking the record of 2.17" in 1951.

Providence tied its record for March 14 with 1.28".

March 14 PM Update: The daily rainfall record at Philadelphia was extended to 2.57". Here are some other new daily rainfall records for March 13 (old record and date in parentheses):
Mt. Pocono PA   1.04" (1.00", 1920)
Newark NJ 3.99" (2.71", 1993)
Central Park NY 3.86" (2.61", 1953)
La Guardia NY 2.88" (2.38", 1993 & 1953)
The new record for Newark is almost 50% above the old one, and it also sets a new all-time daily record for March since daily data began in 1929. The 2.42" at Islip, NY was just short of the 2.49" measured in 1984.
