Temperatures were unseasonable warm throughout the Northeast during November 1999. Delaware averaged 2.9 degrees warmer than the thirty-year mean, while New York averaged 4.4 degrees warmer than normal. The area-weighted average temperature for the twelve-state region was 3.9 degrees warmer than normal and 3.2 degrees warmer than last November. This was warm enough to make it the 2nd warmest November since 1975 and the 6th warmest since comparable records began in 1895.
November precipitation across the northeast region of the country averaged 3.01 inches, which was 79% of normal. All state averages were drier than normal, although West Virginia was the closest with 95% of the long-term mean. Delaware was the driest state in the region with 53% of the normal monthly average. This November was 1.17 inches wetter than the same month a year ago, but was otherwise the driest November since 1990.
