Trenton, NJ. . . . . . . 2.05" (1.90", 1992)
Bridgeport, CT . . . . . 1.64" (1.49", 1992)

Original post:
The strong storm which brought record snowfall to the Gulf Coast has set new daily rainfall records for portions of the Mid Atlantic area. The new records for December 11 (old record and year in parentheses) are:

Martinsburg, WV . . . . 1.92" (1.24", 2002)
Washington Dulles . . . 1.34" (1.09", 2002)
Washington National . . 1.66" (1.36", 2002)
Norfolk, VA . . . . . . 1.77" (1.64", 1888)
Wallops Island, VA . . .2.04" (1.70", 2003)
Richmond, VA . . . . . .2.64" (1.85", 1960)

The totals for Norfolk and Wallops Island are only through 4 pm. The Richmond total is unofficial; if it's correct, it appears to break the all-time daily December record going back to 1887. The projected final total of 2.76" at Norfolk would also smash the all-time daily December record since 1871.

November Warmer Than Average in U. S.


NOAA's National Climatic Data Center today released its analysis showing that November 2008 was warmer than the long-term average across the United States. The monthly average of 44.5°F was 2.0°F above the 20th Century average. For the year so far, the January to November average temperature of 54.9°F was 0.3°F above the 20th Century average. Temperature highlights for November from NOAA:
  • November temperatures were cooler than average across the Southeast and Central regions, and much warmer than average in the Southwest, Northwest and West regions.
  • The West region had its fourth warmest November on record. This contrasted with the Southeast, which was much below normal.
  • Persistent above-average temperatures for the last six months have resulted in a record warm June-November period for the West region. California set a record for its warmest June-November, while both Nevada and Utah had their fifth warmest June-November period.
  • Based on NOAA's Residential Energy Demand Temperature Index, the contiguous U.S. temperature-related energy demand was 0.6 percent below average in November.

Precipitation averaged 1.93" for the month across the U.S. This was about 10% below the 100-year average. Precipitation highlights:
  • The United States measured above-normal precipitation across the northern Great Plains from eastern Montana to western Minnesota. However, November was drier than normal across much of the South and Central regions.
  • Precipitation across most of the Midwest was only 50-75 percent of normal and some areas from southern Missouri through central Illinois received less than 50 percent of normal precipitation.
  • The January-November period has been persistently wet across much of the country from the central Plains to the Northeast. The 11-month period was the wettest on record for New Hampshire and Massachusetts, second wettest for Missouri, third wettest for Vermont and Illinois, and fifth wettest for Maine and Iowa.
  • At the end of November, 22 percent of the contiguous United States was in moderate-to-exceptional drought, about the same as October. Meanwhile, extreme-to-exceptional drought conditions continued in the western Carolinas, northeast Georgia, eastern Tennessee, southern Texas, and Hawaii.
  • About 26 percent of the contiguous United States was in moderately-to-extremely wet conditions at the end of November, according to the Palmer Index. This was a decrease of about three percent compared to October.
