SUMMARY OF CLIMATOLOGICAL DATA 
JANUARY 2005



..."BIPOLAR" MONTH...

...TEMPERATURE EXTREMES EACH HALF
BUT WITH ABOVE NORMAL TEMPS OVERALL...
...BELOW NORMAL RAINFALL EXCEPT IN NORTHERN VIRGINIA...

The headlines above cover it all. Indeed, the month of January 2005 seemed "bipolar" (see DCA summary narrative below) with temps well in excess of normal for the first 14 days followed by temps well below normal for the 2nd half of the month. Rather pleasant weather for most early in the month with temps often in the 50s, 60s, and even into the middle 70s and nighttime lows far above the norm. High pressure built southeast from Canada in the last half of the month with a strong upper trough bringing cold air well into the Southeastern US, repeatedly reestablishing itself the latter half of the month. Little snow during the month for most; however, 3" of snow fell in the DC area on the 22nd from a system that generally affected no one else during the time period. Rainfall amounts were above normal in northern and Virginia and well-below normal for most all locations in North and South Carolina.
  • TIMELY REMINDER - Member Paul Bassett brings an email reminder that might be quite helpful. As many of us have endured quite a bit of freezing and thawing this winter (and with more on the way!), might be a good time for those who have antenna/mast connections and guy wires to check their equipment. The large ranges in temperatures (remember first and last of December and again in January?) can greatly impact masts and wiring.

  • THE PASSING OF JOHN BULLOCK - We have received word from his daughter that longtime but inactive member John Bullock of Louisa, Virginia has recently died. In 2001, John informed us that as he was growing older he simply could not make the venture to the backyard to take his readings any longer. He was pleased that Joe Bowers was also an observer in Louisa and would continue providing data from that location.

Annandale - Lowell reports: " January was very warm up to the 14th and even though the second half was cold the average departure for the month was +0.8 F the warmest January since 2002. The precipitation was also above average with a +0.42 inch departure. The lowest temperature was 7 on the 24th and the highest was 68 on the 4th. The daily temperature range of 32F on the 14th was the highest maximum daily temperature range in January since 2000 when it was also 32 F for the daily temperature range. The January rainfall total was 3.76 inches from 12 days with precipitation also the most since 2000. The 2.08 inches of rain recorded on the 14th was the largest precipitation total in a calendar day for January since January 11, 1991 when 2.25 inches was recorded which is still the record for January. The 2.37 inches in 24 hours on January 13th - 14th though sets a new 25-year twenty-four hour precipitation amount for January. The total snowfall for January was 8.1 inches, which was exactly equal to the 25-year average. There were 9 days with measurable snow or flurries and 6 days with measurable snow but most in one day was 3.0 inches. January 23rd was an unusually cold disagreeable day. The maximum temperature was 21 the second lowest maximum temperature for the date in the last 25-years. It also had a 37 mph wind gust and the lowest wind chill (new Scale) for the winter of -9.7 F at 0701. It is also the lowest wind chill recorded at this station since wind chill records were started in 2001. The wind run was 181.3 miles that was the highest wind run since 4-4-2004. The high wind gust of 37 mph from the WSW on the 23rd at 0245 was the strongest wind gust recorded this month. The maximum barometer reading of 30.85 inches on the 28th was the highest recorded since 3-10-1996 when 30.91 inches was recorded. The lowest barometer reading for the month was only 29.64 on the 26th. This was the highest monthly minimum barometer reading since 1984 when 29.67 inches was recorded. The average barometer pressure for the month was 30.23 inches, which was the highest since 1991. It is also interesting that January was the cloudiest January since 1996 and the second cloudiest January in the last 24 years yet the atmospheric pressure averaged the highest since 1991. Records for January (25-Years of records): 2 daily HIGH maximum temperature records: 1, 13; 1 daily LOW maximum temperature record: 22; 1 daily HIGH minimum temperature record: 12; 1 daily LOW minimum temperature : 24; 1 daily HIGH precipitation record: 14; 1 daily HIGH snowfall record: 30.

Arlington - NWS LWX's Strong reports: " RECORDS... A RECORD HIGH TEMPERATURE WAS SET ON THE 1ST WHEN THE TEMPERATURE REACHED 69 DEGREES BREAKING THE PREVIOUS RECORD OF 68 DEGREES IN 1966. A RECORD AMOUNT OF PRECIPITATION FOR THE DAY FELL ON THE 14TH. 1.82 INCHES OF RAIN FELL. THAT BROKE THE PREVIOUS RECORD OF 1.28 INCHES SET IN 1928. SUMMARY... JANUARY 2005 AVERAGED OUT TO NEAR NORMAL BOTH IN PRECIPITATION AND TEMPERATURES...HOWEVER THE MONTH WAS A BIT BIPOLAR. THE FIRST HALF OF THE MONTH WAS VERY WARM WITH FOUR DAYS IN THE SIXTIES AND ONE AFTERNOON THAT EVEN MADE IT INTO THE LOWER 70S. THE SECOND HALF TURNED DECIDEDLY COLD AND FEATURED A FEW MINOR SNOW EVENTS. NEW YEARS DAY STARTED THE YEAR OFF WITH THE WARMEST NEW YEARS DAY EVER...A PARTLY SUNNY DAY WITH A RECORD SETTING DAYTIME HIGH TEMPERATURE JUST SHY OF 70 DEGREES. THRU THE FIRST HALF OF THE MONTH WE WERE AVERAGING MORE THAN TEN DEGREES WARMER THAN THE AVERAGE. ON THE THIRTEENTH THE TEMPERATURE HIT 71 DEGREES...BUT CHANGES WERE ON THE WAY AS COLD CANADIAN AIR WAS ABOUT TO SLAM INTO THE REGION. THE CHANGEOVER DAY WAS THE VERY DAMP 14TH DAY OF THE MONTH. FROM LATE ON THE 13TH THROUGH THE 14TH OVER TWO INCHES OF RAIN FELL ON THE REGION. THAT PRODUCED SOME QUICK STREAM RISES AND SOME AREAS OF FLOODING. AFTER THAT...THE REST OF THE MONTH WAS JUST AS COLD AS THE FIRST HALF WAS WARM. THE SECOND HALF OF THE MONTH AVERAGED MORE THAN TEN DEGREES COLDER THAN AVERAGE. TEN NIGHTS HAD TEMPERATURES IN THE TEENS EVEN IN THE CITY...TWELVE DEGREES BEING THE COLDEST ON BOTH THE 24TH AND 28TH. THERE WERE THREE MAIN SNOW EVENTS DURING JANUARY. THE FIRST WAS A MINOR EVENT WITH LESS THAN AN INCH REPORTED AT THE AIRPORT. THE SECOND WAS THE BIGGEST OF THE SEASON SO FAR WITH THREE INCHES OF SNOW FALLING ON WASHINGTON. THAT STORM RAPIDLY INTENSIFIED AS IT MOVED FURTHER NORTHEAST UP THE COASTLINE AND BROUGHT A MAJOR SNOWSTORM TO THE NORTHEAST CORRIDOR FROM PHILADELPHIA ON UP TO MAINE. THE FINAL EVENT OF THE MONTH WAS A MIXED PRECIPITATION EVENT ON THE 29TH AND 30TH THAT BROUGHT ABOUT TWO INCHES OF SNOW AND SLEET TO THE METRO AREA. PRECIPITATION THAT DAY WENT FROM SNOW TO SLEET TO FREEZING RAIN THEN BACK TO SNOW. " - [ +/- -/+ ] "

Bridgewater - " The temperature for the month was 4.4 degrees above normal, and the precipitation was 1.23 inches below normal. The snowfall was much below normal. There were four mini snows during the month . The average for these snows was .7 inches. More snow occurred north and east of Bridgewater. The snowfall so far this winter has amounted to only 2.75 inches. The first snow occurred on January 16. January was rather quiet and boring. This has been rather typical of this winter so far. We almost had a zero reading this month when the thermometer dropped to one degree on the 24th. Some clouds came in a little before sunup, which kept the thermometer from dropping lower. We haven't had a zero reading for quite a few years. " - [ + - ] 

Centreville - " It seems like January started off as the month that winter forgot with the average daily temperature of 47.4 for the first two weeks being almost 16 above the monthly average of 31.5. Except for the 26th when the temperature rose to 48 and we had to break out the sun block, no other days for the rest of the month made it out of the 30's. We tipped the scales with a high of 69 on January 13th and recorded our lowest temperature of the month on the 24th with 9. The average for the entire month worked out to be 35.1 which is exactly where we should have been with the first half of the month warmth balancing out the last half cold. As usual, the nightly lows were above the monthly average low, this time by 5.9. The hottest day on the 13th at 69 was followed by the rainiest on the 14th with 1.65" and 52% of out monthly total falling in nine hours. That, in turn, brought on a blast of winter, and finally some long awaited snow. Although not up to the January standard of 9.1", we squeezed out enough moisture to accumulate a total of 7.5" during the five snow days of the month. The most snow received was on January 22nd with 2.7" of easily manageable fluff on the ground. Naturally, I had to try to put it back from where it came from with the first outing of the snow blower this year. By the end of January we were running about two-thirds of normal snowfall for the year, so next month we have a lot of catching up to do. Total water accumulation from rain, sleet, and melted snow amounted to 3.18", or 90% of the 3.52" average, and a respectable start to the New Year. " - notes from Paul [ -/+ - ] 

Falls Church - " January 2005 started out warmer than average then by mid month got considerably colder. A few arctic clipper systems came through bringing us cold and snow. Snowfall was average for this month. I'd like to wish everyone at ACON a very Happy and Healthy New Year! " - report from Erica   [ M M ]

Hampton - notes from Dave: " A warm and pleasant start to January, then turning more to normal the first week. Cold weather from mid month on produced a 1 inch snowfall on Jan 19 with traffic woes when temps are only in the 20's . We missed most of the action with the northeast blizzard; however a glaze of ice with thunderstorms on Jan 22 and a dusting of snow. Temperatures overall were near normal with precip below normal. " - [ -/+ - ]

Herndon - Russ reports:" January temperatures averaged above normal, as did precipitation. The monthly average temperature was 2 degrees above normal and precipitation was 0.15" above average. Of note in January were the temperature extremes, with the first half much above normal and the latter half much below normal.
