SUMMARY OF CLIMATOLOGICAL DATA 


FEBRUARY 2010

... MUCH COLDER & WETTER THAN NORMAL
HEAVY SNOW ACROSS THE NORTHERN & WESTERN AREAS
WITH SIGNFICANT SNOW FOR THE CAROLINAS ...

Brrrrrr! What a cold, damp month with daytime average daily highs at month's end well-below normal helping produce average temps, for most, well-below the norm. For the northern extremes of the region, more big snows fell making winter 2009-2010 in those areas one for the records. Just take a look at the monthly and seasonal snow totals in the table below!! And since these online records have been maintained beginning in 1995, we've not had a minimum temperature as low as Joy Winfree's 11 degrees BELOW ZERO on the 21st! A Southern, eastward trekking low just before mid-month brought significant snows for an area that rarely sees much of the white-stuff. Across the coastal plains of Northeast Georgia, South Carolina, and North Carolina, 4 to 7 inch measurements were recorded. Jacksonville, NC measured 8.5" while a few spots in coastal South Carolina reported 10" of snow.
  • WELCOME MONCURE, NC (MON) AND OBSERVER MAC McILWAIN  

    Mac McIlwain has joined our group beginning with January 2010 data. He writes: "I am located near the small town of Moncure, NC which is about 30 miles SW of Raleigh (RDU) at 234 degrees from RDU. I live in a subdivision of about 25 homes, all on large lots of 2-5 acres each. My AMSL is 415ft. That's approx 200 ft above Lake Jordan Reservior. So we have a lot of forest and natural areas surrounding us for 3-8 miles in every direction. We have a population of about 2 persons per acre. My background: 26 yr active duty veteran of the USAF, and an additional 19 yrs working as a civil servant in the Washington DC area with the Department of the Air Force, Department of Commerce, and the Department of Justice. My interest is in the field of electronics since that is what I did in the Air Force but most of it was on the operations side starting with Morse Code, through High Frequency AM, then USB, mostly providing long range high frequency communications for all DoD and Allied aircraft. I also spent 13 years in the Pacific Theatre. Then I branched out into Federal Spectrum Management (which is different than the FCC) doing spectrum management and spectrum planning for everything from VLF to Satellite and everything in between. We always said we controlled Radio Frequencies from Audio to Light. The FCC does the same thing for civilian users. We serviced only Federal Spectrum. A huge task." (Not long after joining, Mac had some health issues- as do we all - but I am happy to report he's on the mend.)

  • THE ECONOMICS AND SOCIAL BENEFITS OF NOAA DATA AND PRODUCTS It is often said that "NOAA is where science gains value for the Nation." The NOAA Economics web site is a central source of information on the economic value and use of NOAA's data & products, in both industry and society. NOAA's environmental observations, analyses, data products, and services provide valuable information that is routinely used in decision making by consumers, industries, and policymakers. For instance, NOAA weather and climate data are used in countless industries, including agriculture, utilities, transportation, construction, engineering, health care, insurance, manufacturing, education, and tourism. In fact, the Department of Commerce's Bureau of Economic Analysis estimates that at least one-third of the U.S. Gross Domestic Product is weather and climate sensitive.

    Virginia:

    Arlington - From NWS WBC come these notes: " IN WASHINGTON DC...FEBRUARY WAS DOMINATED BY RECORD SNOWFALL. FEBRUARY 2010 WAS THE SECOND SNOWIEST FEBRUARY AND SECOND ALL TIME SNOWIEST MONTH EVER...JUST SEVERAL INCHES SHY OF THE ALL TIME SNOWIEST MONTH OF FEBRUARY 1899 WHEN 35.2 INCHES OF SNOW FELL. FOR THE WINTER 2009-2010 SEASON...THROUGH FEB 28TH...56.1 INCHES OF SNOW HAS FALLEN...MAKING IT THE SNOWIEST SEASON ON RECORD IN WASHINGTON. THE PREVIOUS SEASONAL SNOW RECORD WAS 54.4 INCHES THAT FELL DURING THE 1898-1899 SEASON. THE BULK OF THE FEBRUARY SNOW FELL IN THE FIRST 10 DAYS. THREE DIFFERENT LOW PRESSURE SYSTEMS WERE RESPONSIBLE FOR BRINGING 31.9 INCHES OF SNOW TO WASHINGTON DC DURING THIS TIME. THE TWO-DAY SNOWFALL TOTAL OF 17.8 INCHES FEB 5-6 WAS THE FOURTH HIGHEST TWO-DAY SNOWFALL TOTAL ON RECORD FOR WASHINGTON DC. WASHINGTON DC RECORDED TWO SEPARATE DOUBLE DIGIT TWO-DAY SNOWFALLS IN THE SAME MONTH FOR THE FIRST TIME EVER. EVEN MORE REMARKABLE...WAS THAT THE TWO-DAY DOUBLE DIGIT SNOWFALLS FROM FEB 5-6 AND FEB 9-10...OF 10.8 INCHES...OCCURRED SO CLOSE TOGETHER. THIS COMBINED TOTAL OF 28.6 INCHES THAT FELL WAS THE MOST SNOW EVER IN ANY CONTIGUOUS 7-DAY PERIOD IN WASHINGTON DC. THIS ONE WEEK 28.6 INCH TOTAL BEAT THE PREVIOUS HIGHEST CONTIGUOUS WEEKLY SNOWFALL TOTAL OF 28.0 INCHES SET IN 1922...JAN 26 TO FEB 1. THE FEBRUARY SNOW DEPTH AVERAGED 8 INCHES...WHICH WAS THE SECOND HIGHEST AVERAGE MONTHLY SNOW DEPTH EVER...SECOND ONLY TO THE 10 INCH MONTHLY AVERAGE SNOW DEPTH OBSERVED IN FEB 1899. NOTE...THE CLIMATOLOGICAL SNOW DEPTH...OR JUST SNOW DEPTH...AND ROUNDED TO THE NEAREST WHOLE INCH...IS RECORDED ONCE DAILY AT 7 AM LOCAL STANDARD TIME. AT LEAST ONE INCH OR MORE OF SNOW DEPTH WAS OBSERVED FOR 21 DAYS THIS MONTH. THE MOST NUMBER OF DAYS WITH SNOW DEPTH OF AN INCH OR MORE WAS IN FEBRUARY 1905...25 DAYS...FOLLOWED BY 1895 WITH 23 DAYS. THE FEBRUARY 2010 AVERAGE MONTHLY TEMPERATURE WAS BELOW NORMAL BUT NOT EXCESSIVELY SO...RANKING AS 34TH COLDEST FOR FEBRUARY. HOWEVER DAILY MAXIMUM TEMPERATURES WERE PERSISTENTLY BELOW NORMAL...AVERAGING 6.4F BELOW NORMAL. MAX TEMPERATURES ROSE NO HIGHER THAN 50F DURING THE ENTIRE MONTH. ONLY ONE FEBRUARY IN WASHINGTON HAS THE DAILY MAX TEMPERATURE FAILED TO REACH 50...1905...AND THIS MONTH WAS THE FIRST FEBRUARY SINCE 1934 TO ONLY HAVE A MONTHLY MAX OF 50. THE DAILY AVERAGE MIN TEMPERATURE WAS 1.4F BELOW NORMAL. " [ - + ] 

    Bridgewater - " The total snowfall for this winter so far is around 48 inches. My average for a winter snow is around 22 inches. My record is 45.5 inches. So we have had a record-breaking snow this winter. I don't ever remember having 2 super snowstorms in the same winter such as the snows we have had this winter. We have had 3 zero readings this winter, the first zero reading since " - [ - + ] - Clayton sends these notes

    Centreville - Paul notes, quite succinctly: "Snow blower is happy now." - [ - + ]

    Chantilly - Russ reports: " February was certainly one for the record books. It began with below average temperatures and slowly moderated as the month progressed. The high temperature did not break 40 until the 18th. The low didn't manage to get below 32 on only three occasions. The mean temperature was 4.6 below normal. Monthly precipitation was 0.32" above normal at 3.09" and nearly all of it fell as snow. This resulted in many snowfall records being shattered, with a total of 33.7" falling during the month, primarily during the first 10 days. This was 27.6" above normal. My totals are probably low, as there was considerable compacting of wet snow or blowing and drifting in the record-breaking events. I recorded snow/rainfall equivalents on the 2nd (4.5"/0.33"), 3rd (0.25"/.01"), 5th (12"/1.07"), 6th (12"/1.08"), 9th (2.2"/0.22"), 10th (2.0"/0.20") and 15th (0.75"/0.07"). Freezing rain mixed in on the 10th. Dense fog was observed on the 3rd, 4th, 5th, 6th, and 10th. " - [ - + ]

    Dulles - from NWS Sterling (KLWX) come these notes: " NOTE...ALL SNOWFALL AND PRECIPITATIONS TOTALS FOR DULLES REPORTED IN THIS PRODUCT ARE CONSIDERED PRELIMINARY DATA...AND ARE UNDER REVIEW BY THE NWS AND COULD BE UPDATED AFTER THIS REVIEW IS COMPLETE. FEBRUARY WAS DOMINATED BY BELOW NORMAL TEMPERATURES AND RECORD SNOWFALL. AS OF FEB 28TH...A TOTAL OF 73.2 INCHES OF SNOW HAS FALLEN SO FAR THIS 2009-10 SEASON...MAKING IT THE SNOWIEST SEASON ON RECORD AT DULLES. THE PREVIOUS RECORD WAS 61.9 INCHES IN THE 1995-96 SEASON. THREE SNOW EVENTS THAT OCCURRED DURING THE FIRST TEN DAYS OF THE MONTH DROPPED 45.7 INCHES ON DULLES. WHILE ONLY AN ADDITIONAL 0.4 INCHES OF SNOW WAS MEASURED AFTER THE 10TH...IT ADDED TO THE ALL-TIME SNOWIEST MONTH RECORDED IN DULLES HISTORY. THE PREVIOUS SNOWIEST MONTH WAS FEB 2003 WHEN 34.9 INCHES OF SNOW WAS MEASURED. A TWO-DAY SNOWFALL TOTAL OF 32.4 INCHES ON FEB 5-6 WAS THE HIGHEST TWO-DAY SNOWFALL TOTAL FOR DULLES...SMASHING THE PREVIOUS RECORD OF 23.2 INCHES OF SNOW ON JAN 7-8 1996. THE TWO-DAY DOUBLE DIGIT SNOWFALLS FROM FEB 5-6 AND THE 9.3 INCHES ON FEB 9-10 WERE REMARKABLE TO OCCUR SO CLOSE TOGETHER. THE COMBINED 41.7 INCHES OF SNOW THAT FELL DURING THIS TIME WAS THE MOST EVER SNOW IN A ONE WEEK PERIOD AT DULLES...BEATING THE PREVIOUS HIGHEST WEEKLY SNOWFALL TOTAL OF 30.9 INCHES FROM JAN 6-12 1996. THE DAILY 7AM CLIMATOLOGICAL SNOW DEPTH OF 26 INCHES REPORTED ON THE 10TH IS THE RECORD HIGHEST CLIMATOLOGICAL SNOW DEPTH EVER REPORTED AT DULLES. NOTE...THE CLIMATOLOGICAL SNOW DEPTH...OR JUST SNOW DEPTH...AND ROUNDED TO THE NEAREST WHOLE INCH...IS RECORDED ONCE DAILY AT 7 AM LOCAL STANDARD TIME. THE SNOW DEPTH AVERAGE OF 10 INCHES FOR THIS FEB WAS THE HIGHEST AVERAGE MONTHLY SNOW DEPTH ON RECORD. THE PREVIOUS HIGHEST SNOW DEPTH AVERAGE FOR THE MONTH WAS 7 INCHES IN JAN 1996. AT LEAST ONE INCH OF SNOW WAS ON THE GROUND 25 DAYS THIS FEB...WHICH WAS THE MOST NUMBER OF DAYS IN ANY MONTH HAVING MEASURABLE SNOW DEPTH OF AT LEAST AN INCH OF SNOW ON THE GROUND. AN INCH OR MORE OF SNOW WAS MEASURED ON THE GROUND FOR 26 CONSECUTIVE DAYS FROM JAN 31 TO FEB 23...WHICH WAS THE LONGEST SUCH STRETCH ON RECORD. THE MAX TEMPERATURE WAS NOT HIGHER THAN 50F DURING THE ENTIRE MONTH FOR ONLY THE THIRD TIME ON RECORD. THE OTHER MONTHS WHICH DID NOT RECORD A TEMPERATURE GREATER THAN 50F WERE FEB 1969 AND JAN 1977.

    Glen Allen - Lowell Koontz has added these notes: " February was much colder than average as the monthly mean temperature was 34.6F, a -4.5F departure, and was also wetter than average (when compared to Ashland, Virginia records). The average maximum temperature this year was -10.6F lower than last year's. February was the coldest month of the winter even colder than January. This year only one day was greater than or equal to 55F and last year there were 15 days that this occurred. There were 26 days the minimum temperature dropped below freezing. February had 16.1 inches of snow which was a departure of 11.1 inches when compared to Ashland's average February snowfall or 322 percent of normal. The total snowfall for the year is now 28.7 inches and the winter season 41.6 inches. The 3.93 inches of precipitation for February was a +0.93 inch departure when compared to the Ashland, VA average. The maximum precipitation recorded in a day was 1.72 inches on the 5th and 2.50 inches was recorded in a 24 hour period on the 5th and 6th. The snowstorm on the 5th and 6th was the biggest news of the month and would have been much greater if it had been all snow. Rain started at 1840 and was heavy between 2100 and midnight. There was more precipitation in the form of rain than snow. The best estimate was a little over one inch of liquid was snow and at least 1.25 inches was in the form of rain. The maximum wind gust of 29 mph from the north occurred on the 6th at 0142 hours during the storm. See the time-lapse video of the storm split in two parts- The first time lapse includes the first part of the storm, snow to 1840 and stops just after the rain ended. http://www.glenallenweather.com/links/snows09-10/2-5-10.avi The second part of the storm is all snow from the storm's wrap-around effect. I should also add this was the most snow I have ever seen from the backside of a snowstorm. It was a major storm here but was a historic storm in northwest Virginia, Northern VA and MD where all of the precipitation fell as snow!! Note the time-lapse growth of frost crystals on the right of the snow measuring stick. The growth starts at 2145 and becomes large enough that the frost crystals collapse at 0545. The maximum temperature for February was only 59F on the 21st and the lowest minimum was 13F recorded here on the 7th. This year at the Richmond International Airport the highest temperature for the winter season was only 69F on December 3rd 2009. The airport generally averages about four 70F days each winter and there has only been 11 years since the winter of 1925-26 that the temperature never reached 70F. The lowest barometric pressure of the month 29.40 inches was recorded on the 10th and the highest was only 30.44 inches on February 4th. This February was much colder, much wetter, snowier, and cloudier but less windy than February 2009. " - [ - + ] 

    Herndon - Randy notes: " WOW, what a month - one for the record books. February was well below normal for temperature and well above for precipitation - that equates to a lot of snow. The temperatures ranged between a high of 50 and a low of 9. That is the lowest high temperature for any month in the 16 years I have been measuring temps at this site. The average high and low were about 8 and 4 degrees below normal, respectively. On the precipitation side, the month was 1.12" above normal with 3.89" measured. We had three snow events occurring on the 2-3rd when we received 4.6", the biggest on the 5-6th when we received 27.3", and on the 9-10th when we received 9.6". The latter included some sleet and freezing rain. We also had a few other days with light snow during the remainder of the month. The total for the month was 41.9", and that is the most snowfall that I have ever recorded in any month. The total snowfall for the season is now 80.3" which, of course, is an all-time record. This fits right in with most of the mid-Atlantic region, which have set all-time season snowfall records. " - [ - + ]

    Ladysmith - Danny sends these notes: " February brought significantly below normal temperatures and significantly above normal snowfall. The season total (to date) of 44.3" is by far the highest total since I have been keeping records, even going back to my very amateur snow measuring days in Alexandria and Stafford as a young child. This is the most below normal temperatures have been since February 2007. " - [ - - ]
