SUMMARY OF CLIMATOLOGICAL DATA 


DECEMBER 2008


... DECEMBER TEMPERATURES ABOVE NORMAL & WARMER THAN NOVEMBER'S! ...
... BELOW NORMAL SNOWFALL, RAINFALL TOTALS VARY ...

After November's colder-than-normal fall days, December warmed up remarkably with most everyone noting a month warmer than November, a rather unusual, if not unexpected lead up to winter! The exception would be in Northern Virginia where temmperture averages were closer to normal.
  • MEASURING PRECIP FROM FOG    Here's an interesting post from the "message of the day" at CoCoRaHS.org: " It looks like I have 0.02" of dense fog in my gauge! An observer from Washington State writes: 'For the past week - we have had very dense fog and a few days ago I checked my rain gauge and there was 0.02" in it. This morning I checked it again and there was an additional 0.04" in it. Should I report this as precipitation even though it isn't rain or snow?' Great question! Here's our answer: Moisture collected from fog deposition should be reported just like rain. It is useful to mention in your comments that it came from fog. Moisture from dew or frost does NOT count as precipitation (these form from condensation from usually clear skies) and should not be reported as such- "


  • SNOWFALL MEASUREMENT REMINDER from CoCoRAHS    Also from the CoCoRAHS' website comes this: "New Snowfall Depth . . . Report to the tenth of an inch! New snowfall depth is measured to the "tenth" of an inch, not "hundredth" as rainfall is. So when reporting snowfall depth remember only one decimal place. If you are using a regular ruler here is a review of the conversions to the nearest tenth-inch increments: 1/16 = 0.1, 1/8 = 0.1, 3/16 = 0.2, 1/4 = 0.3, 5/16 = 0.3, 3/8 = 0.4, 7/16 = 0.4, 1/2 = 0.5, 9/16 = 0.6, 5/8 = 0.6, 11/16 = 0.7, 3/4 = 0.8, 13/16 = 0.8, 7/8 = 0.9, 15/16 = 0.9 ... "


  • FREEZING RAIN    Here's another reminder from CoCoRAHS: "Freezing rain is rain that falls in liquid form but freezes on contact with the ground and objects above the ground. Do NOT report freezing rain as 'Snow. If you have an inch of freezing rain accumulate, you melt and measure the moisture that has accumulated inside your gauge and you report that as your daily precipitation amount. You report ZERO for your new snow amount (assuming it all fell as rain, and no sleet or snow accumulated). You DO report the total depth of freezing rain that has accumulated on the ground and enter that in the "Total Snow on Ground" column. Again, make a note in your comments section of your report so that we know its freezing rain. A very useful measure of freezing rain is the "radial thickness" of ice on wires, branches, etc. If you can, measure the ice thickness on a wire or branch and report in your "Comments" the average radius of the ice (not the diameter)."

    Virginia:

    Arlington - From NWS WBC come these notes: " THE DECEMBER 2008 AVERAGE MONTHLY TEMPERATURE WAS CLOSE TO NORMAL. ON THE 28TH THE MAX TEMPERATURE OF 70F WAS TIED FOR THE THIRD WARMEST HIGH FOR THAT DATE SINCE 1872. PRECIPITATION FOR DECEMBER 2008 WAS NEAR NORMAL. OVER HALF OF THE DECEMBER PRECIPITATION FELL ON THE 11TH. ONLY A TRACE OF SNOW WAS OBSERVED FOR THE MONTH...ON THE 6TH AND 31ST. WASHINGTON HAS NOT YET HAD MEASURABLE SNOWFALL THIS WINTER SEASON....WHICH IS ONLY THE SECOND TIME THIS HAS OCCURRED THIS DECADE. A 55 MPH WIND GUST WAS RECORDED ON DECEMBER 31ST AS A STRONG COLD FRONT MOVED THROUGH THE AREA. THIS WAS THE HIGHEST WIND GUST MEASURED IN WASHINGTON IN DECEMBER SINCE 55 MPH WAS MEASURED ON DECEMBER 10TH 1992. " [ + - ] 

    Bridgewater - " The precipitation for the year is now 4.82 inches below normal. There was no measurable snow during the month. Snow flurries occurred several days. Crazy temperatures occurred on the 31st. At 5 am, the temperature was 27 degrees. At 6 am, the temperature was 48, and at noon it was 35 degrees with snow flurries. Never saw such crazy temperatures like this. " - [ + - ] - notes from Clayton

    Centreville - " Warmer, drier, and, at least for a millisecond or two, windier; that's how we can describe December 2008 for sunny Centreville in a nutshell. At 10:14 on the 31st an approaching cold front produced some rather windy conditions peaking with a gust of 53 mph out of the NNW. This was the strongest wind gust locally we can recall in recent memory. The monthly average temperature was on the warm side this month. At 38.9, it worked out to be 3.2 above the 35.7 average, average. There was a record high temperature of 68 on the 28th but it hardly came close to the summer-like 79 that was set back in 1998. The average high for December worked out to be modest 1.3 warmer that the predicted 45.9. On the not so modest low temperature end of the temperature gauge, we averaged 30.5; a rather warm 5.0 over the 25.5 normal low for the month. So far this year, the average low temperature departure has worked out to be +4.4. December's reading increased that figure to +4.7 for the year. A monthly low of 13 was entered in our logbook on the 23rd. This though was a good distance away from the record of -4 set back in 1989 and was hardly enough for Santa to pack a jug of antifreeze for his long trip ahead. For the third month in a row we recorded a deficit in the monthly precipitation column. While -0.24 is a rather shallow amount to create a major headline about, December rainfall still gave us a respectable 2.78" of the 3.02" typically expected The greatest 24 hour accumulation occurred on the 11th and 12th when 1.47" fell in the bucket, giving us 49% of our monthly total. For the year, and with a tip of the measuring cup to May for 10.55", we finished the year with 5.61" to the good and a freezer full of ice cubes to help usher in the New Year. Best to all for a great 2009. " - [ + - ] - notes from Paul

    Chantilly - Russ sends these notes: " A fairly mild and uneventful December. The average monthly temperature was 2.0above normal. Total precipitation for the month was 2.67", which was 0.40" below normal. The maximum calendar day rainfall of 1.25" fell on the 11th. Snow flurries were observed on the 21st, along with a minimal amount of freezing rain. Dense fog was observed on the 19th. *Please note, anemometer is currently partially obstructed from the Southeast " - [ + - ]

    Dulles - from NWS Sterling (KLWX) come these notes: " AT DULLES...THE DECEMBER 2008 AVERAGE MONTHLY TEMPERATURE WAS 2.3F ABOVE NORMAL. THE HIGH TEMPERATURE OF 68F ON THE 28TH WAS TIED FOR THE THIRD WARMEST HIGH FOR THAT DATE DATING BACK TO 1963. THE DECEMBER MONTHLY PRECIPITATION WAS SLIGHTLY BELOW NORMAL. OVER HALF OF THE MONTHLY PRECIPITATION WAS RECORDED ON THE 11TH. A TRACE OF SNOW WAS OBSERVED AT DULLES ON FOUR DAYS IN DECEMBER 2008. A 59 MPH WIND GUST WAS REPORTED ON DECEMBER 31ST AS A STRONG COLD FRONT MOVED THROUGH THE AREA. THIS WAS THE STRONGEST DECEMBER WIND GUST MEASURED AT DULLES AIRPORT SO FAR THIS DECADE. " - [ + - ]

    Front Royal - Mike adds these comments: " A strong shortwave moving through the atmosphere on the 1st provided an exciting start to the Christmas season as the wife and I experienced a thunderstorm with snow being the precip type just north of Leesburg, VA as we were cutting down our Christmas tree. Here in Front Royal just a heavy snow shower and the lowest pressure reading of the month of 29.39". The high temperature of 53 on the 5th ended the somewhat mild start to the month. A cold frontal passage late that evening ushered in colder air and temperatures never left the 30's until the 9th . Southwest winds ahead of a strong storm system in the middle part of the country boosted our temperatures back in the mid and upper 50's on the 9th and 10th. On the 11th as that same strong storm system affected our area rain began just after midnight and .14" had fallen in the gauge by 5am that morning and another 1.89" would fall by 11pm when the precip ended. Temperatures fell through the day, but did not cool enough to produce the snowfall that was forecast. Strong northwest winds outshined the early morning rain shower we had on the 12th. Winds gusted to 44mph. A cold frontal passage late on the 15th brought an end to the spring like temperatures. That front stalled in the Carolinas and as waves of low pressure developed along that front bouts of precipitation affected the Shenandoah Valley. While some of that was in the frozen form it did not cause any major problems or add a measurable reading into the snowfall column. A wave of low pressure rode an easterly line in Pennsylvania on the 19th. Again the 50 high and 39 low for the day were too high for any substantial winter precipitation besides some sleet during the onset. The coldest weather of the month arrived after the cold frontal passage on the 21st. It would also be the last day any measurable precipitation fell here in Front Royal. The 22nd was clearly the coldest day of the month with a high of 26 and low of 14, but the 14 was overshadowed by the 12 on the morning of the 23rd. That day also achieved the highest pressure reading of 30.67". Fast-forwarding to the 28th and the 71 high and forecast for the rest of the month I realized that this month would have no measurable snowfall. Another strong cold front passed by on the 31st and very windy conditions ended the year. A 52mph gust was recorded here. " - [ M M ]

    Glen Allen - Lowell Koontz sends these additional notes: " December was warmer than average as the monthly mean temperature was 43.19F, a +4.2F departure, and was also wetter than average (when compared to Ashland, Virginia records).
