    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

    Herndon - Randy adds these notes: " THE DRIEST YEAR ON RECORD IS NOW IN THE BOOKS. DECEMBER WAS AT NORMAL IN TEMPERATURE, AND SLIGHTLY ABOVE NORMAL IN PRECIPITATION. HOWEVER, THERE WAS NO WAY WE WERE GOING TO MAKE UP THE 15 INCH PRECIPITATION DEFICIT GOING INTO THE MONTH. RAIN DID FALL OFF AND ON MOST OF THE MONTH, BUT MOST OF THE AMOUNTS WERE 0.20 TO 0.30 INCHES. OVERALL WE RECEIVED 3.30 INCHES SLIGHTLY ABOVE THE 3.04 MONTHLY AVERAGE. FOR THE YEAR, WE TOTALED ONLY 30.37 INCHES, WELL BELOW THE 45 INCHES THAT I HAVE AVERAGED OVER THE LAST 15 YEARS. WE DID GET OUR YEAR'S FIRST SNOWFALL WITH 3.1 INCHES FALLING ON THE 5TH. THE SNOW WAS ALL GONE BY THE 8TH WHEN OUR TEMPERATURES WERE BACK INTO THE 50S. THIS WAS THE ONLY SNOW SEEN DURING THE MONTH. DURING THE YEAR, WE HAD 8 MONTHS OF BELOW NORMAN RAINFALL AND ONLY 4 MONTHS OF ABOVE NORMAL PRECIP. AS FOR THE TEMPERATURES, THE AVERAGE HIGH WAS ALMOST 2 DEGREES BELOW NORMAL AND THE AVERAGE LOW WAS ALMOST 2 DEGREES BELOW NORMAL; GIVING US A NORMAL MONTH. " - [ + + ]

Drought was definitely the major headline for 2007, with 10 of 12 months bringing below normal precipitation and the annual total only 54% of 2006's annual total. A happy and prosperous 2008 to all!
