SUMMARY OF CLIMATOLOGICAL DATA 


JANUARY 2007


... THE WARMTH OF DECEMBER CONTINUED INTO MID JANUARY 2007

MOST AREAS REMAINED DRY ...

The well-above average temperatures of December continued into mid-January when winter cold finally arrived (and would last into early March!) For winter-weather lovers, the prospects for snowfall dimmed as above normal temperatures and the lack of significant storms for the Mid-Atlantic prevailed. Some wintry weather was reported across the Carolinas between the 18th and 21st.

  • A HISTORY OF OBSERVING THE WEATHER    Weather observations, including temperature, moisture, pressure, and wind speed and direction, are the basis for the weather forecasts we rely on every day. NOAA's National Weather Service has been observing the weather since the 19th century and continues to serve as the primary source of weather data, forecasts, and warnings for the United States. For more, visit http://celebrating200years.noaa.gov/foundations/weather_obs/welcome.html#earlyyear.


  • CERTIFICATE OF ACHIEVEMENT IN WEATHER FORECASTING    Whether you are an amateur weather enthusiast or a weather-related industry professional, enrolling in this online certificate program is a perfect way to enhance your career or degree. Through the online meteorology courses that compose this 12-credit certificate program of study, you can build a foundational understanding of contemporary forecasting techniques. For more details, visit http://www.worldcampus.psu.edu/WeatherForecastingCertificate_WeatherForecasting.shtml.


  • EASTERN US WEATHER CONFERENCE    This year's conference information has been posted. The event will be held in Philadelphia from June 22 - June 24. For details, visit http://www.easternuswx.com/conference/.


  • ICELAND FEARS BEARS THAT GO WITH THE FLOE    The oceans may be warming and air temperatures rising, but in recent days Iceland has bucked the global climate trend. Curious now... read on here http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2007/02/04/wbears04.xml. Thanks to Kevin Shaw for this link.


  • 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!

    Annandale - Lowell notes: " January was the fifth warmest January on record in the past 27 years. January had the greatest number of precipitation days for January since 1998 but was the 9th driest January in the last 27 years. January was the fifth warmest January on record in the past 27 years with a mean temperature of 39.6 F and a +5.4 F departure for the month and a little below average in precipitation. January last year was the warmest January on record here. The highest temperature was 71 F on the 6th and the lowest temperature was 14 F on the 26th but the average January minimum temperature is 9 F. The 71 F maximum was only three degrees from being the warmest temperature in January in the last 27 years! Also on the 6th a dew point temperature of 63.4 F was recorded, a very high value for January. The daily temperature range of 36 F on the 27th was the highest maximum daily temperature range in January since 1996. January was a dichotomy with the first 16 days being very warm for January and the second half of the month being near average but feeling colder than that due to the extraordinary warmth of the first half of the month. The January precipitation total was 2.69 inches from 13 days with precipitation that was the greatest number of precipitation days for January since 1998 but was the 9th driest January in the last 27 years. January was a just a little above average in cloud coverage. The precipitation departure was -0.66 inches. The total snowfall for January was 1.8 inches which was a departure of - 6.0 inches which was much below average but last year in January we had only a trace of snow. The high wind gust of 37 mph occurred on two days. The west wind on the 19th at 1001 was 37 mph and on the 20th at 0628 from the WSW was also 37 mph. The maximum barometer reading of 30.76 inches on the 17th was the highest barometric reading recorded since January 28, 2005. The lowest barometer reading for the month was only 29.62 on the 28th which was the fifth highest minimum monthly barometer reading for January in the last 27 years, as there was no major storm system this month. 11 January DAILY Records Tied or Broken- (27-Years of records): 2 HIGH maximum temperature: 6, 15; 5 HIGH minimum temperature: 1, 5, 6, 13, 14; 2 HIGH range temperature: 16, 27; 2 LOW range temperature: 21, 24.

    Arlington from NWS in Sterling - " JANUARY WAS A SPLIT MONTH FOR WEATHER. THE FIRST HALF WAS A CONTINUATION OF DECEMBER AND WAS EXCEEDINGLY WARM... WHILE THE SECOND HALF WAS MORE JANUARY LIKE WITH SEASONABLE TEMPERATURES AND A FEW MINOR SNOW EVENTS. THE FIRST HALF OF THE MONTH WAS VERY WARM. THERE WERE SIX DAYS THAT REACHED HIGHS IN THE 60S AND 70S. IT WAS THE SECOND WARMEST FIRST HALF OF JANUARY ON RECORD...ONLY SLIGHTLY BEATEN BY THE EXCEPTIONAL MONTH OF JANUARY 1950 THAT WAS OUR WARMEST JANUARY ON RECORD. IT ALSO WAS A CONTINUATION OF THE WARM START TO THE WINTER SEASON. THE PERIOD OF THANKSGIVING THROUGH JANUARY 15TH WAS THE WARMEST SUCH PERIOD ON RECORD FOR WASHINGTON. THE SECOND HALF OF THE MONTH WAS A DIFFERENT MATTER. IT WAS MARKED BY NEAR NORMAL TEMPERATURES FOR JANUARY AND A FEW MINOR SNOW EVENTS. MOST OF THEM WERE JUST FLURRIES BLOWING THROUGH THE AIR. HOWEVER... THE 21ST ACTUALLY HAD OUR ONLY MEASURABLE SNOW OF THE WINTER SO FAR WITH JUST OVER AN INCH REPORTED AT NATIONAL AIRPORT. " [ + - ] 

    Bridgewater - " The temperature was 2.7 degrees above normal while the precipitation was .78 inches below normal. The total snowfall was 1.5 inches which was the total for the winter. We usually get 22-24 inches on the average for a winter. " - [ + - ] - remarks from Clayton

    Centreville - " Hot notes from the oasis of Northern Virginia. With buds on the trees and Daffodil shoots making an appearance, it won't be long before the tourists begin to arrive. The temperatures for January came in at 8.2 above the 31.5 average monthly temperature at 39.7; OK, call it 40. Twenty days had readings above the 41.2 average monthly high with the warmest daily high being on January 6th with a 71 reading. During the last week of the month we picked up some winter-like lows, but the palms pulled through none-the-less. Six of the last seven days had nightly lows of 20 or less with 16 being the lowest on the 26th and 30th. Only two other days of the month had low temperatures less than the published average monthly low of 21.8. The logged average low temperature of 31.7 was 9.9 warmer than normal and exceeded the overall monthly average temperature by 0.2. All forms of precipitation for this time of the year have been getting the short end of the measuring stick it seems. Normal snowfall for January is 9.1"; we got 2.2". Normal snow accumulation for the season is 11.6"; we got 2.2" and a trace or two. In the rain column we didn't seem to do much better either. January 1st got off to a good start with rain from midnight thru 1530, then partial clearing for the rest of the holiday. Only 0.68" was all we managed from that and it was the greatest single event amount all month that gave us 26% of our 2.57" total. That happens to be 0.95" shy of the 3.52" January average the record books show as being normal. " - [ + - ] - report from Paul

    Falls Church - " Milder first half of the month then becoming more seasonable the later half. Above average rainfall but below average snowfall. My peak wind gust for the month occurred on 1/26 with 37 mph. " - [ + + ] - notes from Windie

    Chantilly - Russ Topping reports from his new location in Chantilly: " January 2007 started off very mild and wet and ended cold and dry.

Monthly precipitation was 0.71" below normal. Snowfall was 6.1" below normal. We got our first measurable snow of the season very late, with 2.0" of snow and freezing rain to top it off on the 21st. A few flurries on the 24th, but just a trace. " - [ + - ]

    Herndon - Randy sends these additional notes: " JANUARY BEGAN THE YEAR WITH WELL ABOVE NORMAL TERMPERATURES FOR THE FIRST 16 DAYS UNTIL A FRONTAL SYSTEM PUSHED THROUGH AND BROUGHT US BACK TO MORE NORMAL TEMPS FOR THE REMAINING TWO WEEKS OF THE MONTH. THE HIGHS ENDED UP OVER 4 DEGREES ABOVE NORMAL AND THE LOWS WERE 5 DEGREES ABOVE NORMAL. PRECIPITATION FELL OFF AND ON ALL MONTH WITH THE HEAVIEST RAIN FALLING ON THE 1ST WITH ABOUT TWO-THIRDS OF AN INCH FALLING. WE FINALLY RECEIVED OUR FIRST MEASUREABLE SNOWFALL OF THE SEASON ON JAN 21. WE RECEIVED 1.8" BEFORE THE SNOW TURNED TO SLEET THEN FREEZING DRIZZLE. SNOW FLURRIES FELL ON SEVERAL OTHER DAYS BEFORE AND AFTER THE 21ST WITH THE TOTAL SNOWFALL FOR THE MONTH AT 1.9 INCHES. THE MONTH FINISHED AT ABOUT AN INCH BELOW NORMAL FOR PRECIP. " - [ + - ]

    Ladysmith - Danny adds these additional notes: " The streak of above normal temperatures continues! Despite much cooler weather at the end of the month, January finishes nearly 5 degrees above normal (5 of the last 6 months have featured above normal temperatures). Some light snow preceded a wintry mix on the 21st, bringing a total of 0.8" of snowfall--the first of the season. Precipitation was slightly below normal for the second straight month. " - [ + - ]

    Portsmouth - " With regard to temps, the first half of the month continued the warm temps of December; but the 2nd half of the month was colder than normal. For the month the temperature average (45.4) was nearly 5 (+4.9) above the norm. In fact, January 2007 was the 5th warmest on record since the database commenced in 1976. The month was slightly cooler than in 1999 (46.0) and slightly warmer that in 1989 (45.7). Rainfall was nearly 1 inch below normal (-0.91"). Frost was observed on 6 days.

    Greensboro - NWS Raleigh (RAH) reports: " A NEW RECORD HIGH OF 71 WAS RECORDED ON THE 14TH... WHICH BROKE THE OLD RECORD OF 68 SET IN 1995, 1952, AND 1932."

    Raleigh - NWS Raleigh (RAH) reports: " January 2007 was much warmer and slightly drier than normal. The first two weeks of January felt more like April than the middle of winter. The temperatures soared into the 70s on several days, which tied or set several daily record highs. There were also days in which the average temperatures were as much as 25 to 27 degrees above normal, namely January 5th and 15th. During the first 16 days of the month, Raleigh-Durham averaged 13.4 degrees above normal, while Greensboro averaged 13 degrees above normal. Both sites were on pace to set the all time warmest January on record. Then, like a flip of a switch, there was an abrupt pattern change from warm to cold. The temperatures during the last two weeks of the month averaged 2 to 3 degrees below normal. The colder temperatures during the latter half of the month were not cold enough to offset the excessive warmth during the early part of the month, however. Overall, the temperatures finished the month averaging 2 to 6 degrees above normal across the state. The January monthly average temperature for selected locations is depicted in figure 1. It was even warmer over regions of the United States and around the world in January 2007. For a review of global temperatures experienced in January 2007, click on the following link: http://www.noaanews.noaa.gov/stories2007/s2798.htm. There were several wintry precipitation events that accompanied the colder temperatures, including events on January 18th and January 21st. Despite the wintry precipitation events, the month of January was slightly drier than the 30 year average at the majority of the reporting sites. Rainfall amounts generally averaged between 0.50 and 2 inches below normal across the state."

Precipitation for January was 1.09" below normal. No severe weather was noted in January, but a tornado watch was in effect for a good part of January 5th. " - [ + - ]
