SUMMARY OF CLIMATOLOGICAL DATA 
DECEMBER 2002

...Temperatures Well-Below Normal Arrive With the Month
Bringing The Season's First Major Winter Events...
...Temps Warm Up In The 2nd Half...
...First Below 0F Readings Recorded...



Greetings folks and a Happy New Year to all in these uncertain times.

An East Coast upper trough set up for much of early December. A winter storm developed over the southeast US bringing 5"+ snows to Western & Northern Virginia and a mix further south, even into the Carolinas with Raleigh suffering through an early winter ice storm. The second major event occurred at Christmas with 1"+ rains and even some snow across northwestern and northern Virginia and low pressure moved north, northeast through the central and eastern portions of the area. Of particular note during the holidays, rather low barometric pressure readings were recorded. Also of note, rainfall along the coasts of North and South Carolina was below normal (except at Charleston)

Details are covered quite accurately in your monthly notes below.

  • Monthly Hydrologic Summaries End:  Susan Funk of NWS Wakefield has informed me that the office no longer produces a monthly hydrologic report for its area of responsibility. Thus, your reports become even more important each month right here. Many thanks to you all as you continue your consistent and diligent work in maintaining climatological records for your vicinity. Perhaps one of you would now like to produce a monthly narrative summary for the entire area. It's simply a matter of tracking the weather for each month by utilizing online resources, then writing a brief summary covering general conditions and extremes. No data lists need be incorporated herein. So, let me know if you're interested!
  • Paul Bassett Adds This On Instrument Calibration A point of interest to add to your suggestions for equipment maintenance is the condition of the ground(ing) system. All connections should be tight both in and out of the house, that's a primary point. An item of equal importance, but perhaps a little less known, concerns the method of connecting items to the ground buss. Essentially, each electronic instrument requiring a ground connection should be connected directly to the ground buss as opposed to using the "spider web" approach when items are looped through each other before finally attaching to the buss. The ground buss should be attached to a copper water pipe (as opposed to a PVC water pipe) with a clamp for that purpose. At last... I say "items requiring a ground connection" because many don't. An external modem using a two prong power supply is one example of an item more than likely not needing a dedicated ground wire. An H.F. receiver (not to mention HAM radio equipment) used near a computer is an example of equipment needing special grounding attention. Just a thought that I hope will help.
  • Call for Weather WebCams Around The Region:  If you would be so kind, please send the URL addresses for webcams- hopefully near real-time - that you have located across our three+ state area. Just today I found several including Roanoke, Lynchburg, Danville, Blacksburg (NRV), and Smith Mt. Lake at The Lynchburg News & Advance.com. Be sure to click on the Towercam tab.
  • Danny Jessee of Stafford Returns:  As you may recall, Danny Jessee left our ACON group several years ago to pursue his undergraduate work at UVA. He's back and writes, " I was an ACON member from 1997-1999, before heading to college down at UVA. I'll be graduating this spring with degrees in Environmental Science and Computer Science and will be living in Stafford, VA again. I have also finally joined the weather station revolution and now have my own fully-functional, automated home weather station. With that in mind, I would like to become a member of ACON (and reactivate my old station, KSTF) once again. I will not be able to provide full monthly summaries again until the end of February, but I would like to become an ACON member again as soon as possible. My weather station is up and reporting at http://www.dannyjessee.com/liveweather." Indeed, you are welcomed back by all and we'll check for your February data soon.

Virginia:

Annandale - Lowell reports:" December was the coldest month of the year and had above average precipitation. The lowest temperature was 16 on the 7th which tied for the annual minimum temperature that also occurred on March 5th 2002. It was the coldest December since 2000 when the mean monthly temperature averaged a full 6 colder than this December. The snow total on December 5th of 5.0 inches set a new 22 year maximum snowfall record for the date and the first snow to be recorded on this date! It was also the earliest measurable snow ever recorded in December and the second earliest of this magnitude recorded in the fall season in the last 22 years. Only the Veteran's Day Storm of 11-11-1987 was earlier and of a greater magnitude. The record amount of precipitation for Christmas day of 0.86 inches was a new 22 year maximum precipitation record for the date; the old record was only 0.28 inches in 1997. Annandale Weather Center had 0.4 inches of snow and sleet on Christmas morning making it the first white Christmas since 1993 when 1.4 inches fell on Christmas night with a cold frontal passage! December also had the highest snowfall total (6.5 inches) since 1989 when 14.2 inches occurred. The December average mean temperature was 35.76 with a departure of -2.08 and is only the second month of 2002 to have a negative temperature departure and was the cloudiest December since 1998. The December rainfall had a surplus of +1.37 inches which was the most rain in December since 1996. Two days had precipitation amounts that set new 22-year records for the date. For the year, we now have a deficit of -6.03 inches in precipitation and with last year's deficit of -7.84 inches we are still behind a total of -13.87 inches. In September this deficit was -19.07 inches. The maximum gust of 36 mph from the west on the 26th at 2100 hours was the highest wind gust recorded this month. The minimum barometer reading of 29.30 inches on the 25th was the lowest recorded since 12-18-2001 when 29.29 inches was recorded. December DAILY Records Tied or Broken (22-Years of records): December had 3 daily LOW maximum 22-year temperature record/s for the date: 1, 4, 5; December had 3 daily LOW minimum 22-year temperature record/s for the date: 4, 6, 7; December had 3 daily LOW range 22-year temperature record/s for the date: 5, 11, 25; December had 2 daily HIGH 22-year precipitation record/s for the date: 11, 25; December had 2 daily HIGH 22-year snowfall record/s for the date: 5, 24.

Arlington - NWS WBC's Dewey Walston reports: RECORD DAILY SNOWFALL OF 6.1" SET ON DECEMBER 5TH. THE OLD RECORD WAS 4.5" SET IN 1910. DECEMBER 2002 CONTINUED THE PATTERN ESTABLISHED IN THE SECOND HALF OF OCTOBER INTO NOVEMBER OF COLDER THAN NORMAL TEMPERATURES AND SURPLUS RAINFALL. THAT EXCESS RAINFALL HELPED TO RECHARGE GROUNDWATER THAT WAS REDUCED TO EXTRAORDINARILY LOW LEVELS DURING THE DROUGHT. IN ADDITION...THE 7.1 INCHES OF SNOW MADE IT THE SNOWIEST DECEMBER SINCE 1989 WHEN 9.0 INCHES FELL. Rainfall for the month was 1.40" above normal while average temps were 2.3 below normal. The average wind speed was 8.8 mph. [ - + ]

Ashburn - Gary Oldham checks in: " December seems to be the month for records at my station. A new low temp record was set on the 7th at 4.5. A new high barometric pressure was set on the 9th at 30.683 inHg. On Christmas Day, the barometer came within .02" of setting a new low record. December also set a new high for heating degree days at 952.5 (using the integration method) and was the first month on record with NO Cooling Degree Days. My anemometer was out of service between 21 November and 13 December; the first several days of December were quite windy, and almost undoubtedly exceeded my "declared" high wind speed of 29 MPH on the 25th. The cause of the anemometer failure was ultimately determined to be a bad Sensor Interface Module on my Vantage Pro station and was only determined after the anemometer itself was replaced. This is the third SIM board on my station in its short 18 month life. December's temperature was 1.8 below normal. The mean humidity was 65% and the mean dew point for the month was 23. The snowfall on the 4th through the 6th totaled 5.6" and was the first measurable snowfall of the season, starting with huge flakes and snowing steadily through much of the 5th. " [ - - ]

Blacksburg - NWS Blacksburg reports the monthly mean temp was 1.2 below normal while rainfall was 0.94" above normal. [ - + ]

Bridgewater - " The average temperature for the month was 2.1 below normal, and the precipitation was about an inch above normal. The -5 on the 7th was the first zero reading since 1996. Snow on the ground contributed to the low reading. Snow on the 5th was beautiful, and covered most of Virginia and neighboring states. A half inch of snow that occurred on Christmas Eve and Christmas morning gave us a white Christmas. According to my records, this is only the 7th white Christmas that has occurred in the past 38 years. notes from Clayton [ - + ]

Centreville - Our average high of 42 and our average low of 26 happened to both come together on December 7th. Those two temperatures averaged below the statistical monthly average of averages of 34.9 by a slight one-degree. The extremes for the month helped to keep the averages about average too. The lowest temperature of 12 recorded on December 4th and the highest of 59 on the 31st worked out to be about of the 34.9 median of the means. Need I remind us of a record 81 on December 8th, just four years ago? The average low temperature for this month of 25.9 was just 2.6 above from where we ought to be. March was the only other month in 2002 when the reported and the statistical low temperatures were so close. Now, that should get us back down from the palm trees for a while Centreville was on the plus side in the precipitation department again thanks to 6.8" of snow; nearly 5" more that the official snow book says we should have received. Thank goodness Santa & Co. were able to get their deliveries done on schedule once again. Having to navigate the routes around Centreville a day later would have put a different spin on things. This year we had out first snowfall on Christmas Day in 33 years when 0.9" began to accumulate on out terra firma in the morning. Not a big deal by Santa's standards, but later that day, with the barometer bottoming out at 29.32" around noon, the winds began to pick-up and at 10:30 pm a gust of 42 mph out of the northwest could have really upset his gyros. For December totals after mixing the water equivalent of snow with real rain, drizzle, grauple, and a wayward wren, 4.21" went in the logbook and the indications are that we were 0.92" in excess above the 3.29" normal. It wasn't until October that I began to record a monthly rain surplus that continued throughout the rest of the year. The generosity of the precip people above began to cut our measured deficit from 7.37" in September to just 1.94", a 75% reduction, in just three months. A set of facts such as these don't do anyone much good except to note that after nearly two years, our drought conditions might be becoming less severe. We can hope. " - notes from Paul [ +/- + ]

Charlottesville - The monthly average temperature was 4.0 below normal while rainfall was 1.12" above normal. The average wind speed was 5.4 mph. [ - + ]

Dulles - The mean temp was 2.6 below normal. The monthly rainfall was 0.54" above normal. Average wind speed, 5.9 mph. - from NWS WBC [ - + ]

Falls Church - " December 2002 was a colder and wetter than average month. We also saw our first major snow of the season on the 5th. I had 5" here in Falls Church. The real treat came Christmas Eve and Day where we finally had a white Christmas here in Washington. It had been quite some time since there has been snow on the ground for Christmas. I'd like to wish everyone a Happy New Year!!!!! " - notes from Erica [ - + ]

Hampton - Report from Dave: " MONTHLY RECORDS: DAILY PRECIP RECORD 2.00 ON 12/5 AND A RECORD LOW MAX 37 ON 12/6. SUMMARY: COLD WEATHER WAS THE WORD FOR MOST OF THIS MONTH WITH AN NEAR MISS EARLY SNOW/ICE EVENT ON THE PENINSULA. A STRONG AREA OF LOW PRESSURE WITH A BAROMETRIC PRESSURE OF 29.30 INCHES CHRISTMAS DAY AND STRONG WIND GUST OF 40-45 MPH, HOWEVER NO SNOW!!! THE MONTH CLOSED ON A VERY MILD SPELL THAT I HOPE DOES NOT SIGNAL A MILD WINTER! THOSE OF US WHO LIKE SNOW, COLD AND BLIZZARDS (I ONE OF THEM) ARE PRAYING FOR THE NEGATIVE NAO. HAPPY SLEDDING!!

We had 5.5 inches of snow on December 5th, which set a daily record and was the 2nd greatest snowfall to occur so early in the year. Snow also fell on the 24th (1 inch) and 25th (2 inches) to give us a rare White Christmas in the Washington, DC area. An ice storm on the 11th brought down many large tree limbs, as it accumulated 3/8 inches on our trees. We received 1.27 inches of freezing rain in 5 hours. Sleet mixed with our beautiful snowfall on Christmas Day, keeping the snow depth down. " - notes from Russ [ - + ]

Lexington - Scott from WREL notes: " Average temperature in Lexington was 34.0 which is 3.5 below normal. Of note was our monthly low temperature of 3.0 which occurred under a very cold ridge. This was also our lowest temperature reading since January, 2000...nearly 2 years! Average rainfall is 2.96 so our total of 3.05" was about normal. This was also the fourth straight month our precipitation exceeded monthly norms. Snowfall of 6.75" primarily was from the system that passed the Mid-Atlantic on 12/4-12/5. This event produced widespread 5"-6" totals in the Shenandoah Valley. We also recorded *half* a White Christmas! 0.75" of snow fell early on December 25, however by 12 Noon temperatures were in the mid-thirties so our snow quickly melted. Also, based on Wind Run, December was the windiest month of the year, yet did not produce the highest wind gust of 2002. " [ - + ]
