WE WELCOME BACK MEMBER RUSS TOPPING Russ, as you may remember, moved from Herndon to Chantilly. After adjusting to his new home and setting up a new station there, he will be submitting data henceforth from Chantilly, Virginia (see link to location map in the station abbreviations below). Welcome back Russ!
WEATHER INSTRUMENTS FOR AUCTION AT EBAY! We were reminded recently in an email from ACON MD/DE/DC member Kevin Shaw that you can visit the Ebay website and conduct a search for weather instruments. At times there are some super buys and if you're into auctioning, might be worth your time. Indeed, Kevin's web friend Larry noted a recent auction of a Belfort Instruments Microbarograph for an amazing $310 (and just calibrated!). In the 1970s he purchased one for about $325; in recent years, Larry noted Belfort has been selling this instrument for over over $4700. So, this might be a good place for you to look for new and vintage weather instruments!

There were no damaging storms of any kind here in Bridgewater.The biggest news story was the wet weather during the late summer and the fall season. Otherwise the year was rather calm. " - [ + - ] - remarks notes from Clayton
Centreville - " Except for another lump of coal in my stocking, the news for this month is pretty mild. A record high of 75° on December 1st was the greatest single contributor to increasing our overall monthly average temperature by over one degree to 7.4°. In fact, 7.4° was the magic number across the board in December. Not to claim any unfair advantage over the other monthly temperature averages, nightly lows also registered 7.4ø above the documented average monthly low reading of 32.9ø. Two mornings had lows in the teens with 16° being the lowest on December 9th. That was preceded by 19° just a day earlier. Only eight nights during December had readings in the 20's with the warmest being 48° on the 14th. All the moisture that could have been snow found another state in which to chill. Precipitation was at a premium in the greater Centreville metro area with only 1.51", or 50% of our normal 3.02" falling. These calculations point out that there was a 1.51" deficit for December as well. If you think my 7.4 stuff was confusing, you should'a been around when 1.51 appeared a couple of times. Anyway, for the year we accumulated 47.93", coming out ahead by 5.32" over our 42.61" normal. The average annual low temperature deviation was +5.9° with December placing second warmest for the year after January with its +11.7ø. Happy New Year! " - [ + - ] - report from Paul

Greensboro - NWS Raleigh (RAH) reports: " The December 2006 North Carolina Weather Review is located here: http://www.erh.noaa.gov/rah/ncsummaries/MonthlySummary.Dec.2006.doc. See notes for Raleigh below. " - [ + - ]
Raleigh - NWS Raleigh (RAH) reports: " December 2006 was the fifth warmest December on record in Raleigh-Durham. December 2006 will be remembered as one of the warmest on record across North Carolina. The monthly average temperatures turned out to generally range between 3 and 6 degrees above the 30 year mean. The December monthly average temperature for selected locations is depicted in figure 1. The month marked the fifth warmest December on record averaging 47.8 degrees (4.8 degrees above normal). Unlike in previous months, there was a long extended period of dry weather to go along with the warmth. The dry period lasted for the first three weeks of the month. Locations such as Fayetteville, Greensboro, and Raleigh recorded only two days with measurable rainfall during this 3 week span. The rainfall was very light as Fayetteville tallied only 0.07 of an inch, Greensboro 0.19 of an inch, and Raleigh-Durham totaled only 0.55 of an inch. Much wetter conditions returned by the last week of the month as two significant rain events hit the state. The rainfall during the last week of the month was sufficiently heavy enough to thrust the monthly totals to at or above normal levels at many reporting stations. The December 2006 North Carolina Weather Review is located here: http://www.erh.noaa.gov/rah/ncsummaries/MonthlySummary.Dec.2006.doc. " - [ + - ]
