TWO PERIODS OF HIGH WINDS OCCURRED DURING THE MONTH. A STRONG COLD FRONT ON THE 3RD USHERED IN HIGH WINDS AND MUCH COLDER AIR.

Bridgewater - " The precipitation for the month was .56 inches above normal while the temperature was 4.1 degrees above normal. The average temperature for the year was above normal. The precipitation for the year was nearly 6 inches below normal. There were no big weather events that occurred during the year. " - [ + + ] - report from Clayton
Centreville - Paul sends these notes: " With temperatures running a little above normal for the Yule fest, Santa, his reindeer along with "Rudy" had a spring like welcome to sunny Centreville. By noontime with the jolly gift giver well on his way and wrapping and ribbons snuggly in the compactor, the temperature registered a comfortable 46°; also the average daily maximum for the month. The high end of the temperature scale was reached on December 12th with a 62° reading; a good distance away from the December record of 79° set back in 1998. Our average temperature of 39° was just 3.3° above our suggested value of 35.7°. On the 6th, 17° marked the low spot of a rather brief frigid period of the month. No other days recorded readings in the teens, and only eight days saw lows in the 20's. The low average for December came in at 32.3°; 6.8° above our computed 25.5° which is just a few tenths off from the average deviation of average lows for the year. That happens to be 6.8° above the published average low. Precipitation amounted to 100% of the monthly average value; 2.79" from rain, 0.23" coming from melted snow. And while in the subject of snow, we were treated to 3.1" on December 5th, some of which managed to remain on the ground in spots until the temperature and some rainfall melted what still survived. A slight lack of snow early in the winter season was overcome by the December 5th event and gave us a surplus of 0.6" for the year. Happy snowboarding! " - [ + -/+ ] - notes from Paul
Chantilly - Russ Topping reports: " December showed a slight wrinkle in the dominant pattern for 2007... temperatures above normal again, but precipitation actually normal.
