SUMMARY OF CLIMATOLOGICAL DATA 
FEBRUARY 2005



...TEMPERATURES GENERALLY ABOVE NORMAL...

...OVERALL PRECIPITATION BELOW NORMAL WHILE
SNOWFALL TOTALS IMPROVE FOR AREAS ACCUSTOMED TO SNOW...

As your reports suggest, not a lot to talk about in February 2005. A scan of the data indicates maximum temperatures were about the same as January's but minimum temperature averages rose above those in the previous month. Overall, temperatures were above normal while rainfall was below normal. As mentioned earlier, snowfall totals increased for those of you in snow prone areas. As always, a read of Raleigh's extensive summary in the link below (narratives) provides a good overview of our weather.
  • AVERAGE VERSUS MEAN? - Albert Arnold of Chesterfield County in Virginia (Winterpock) engaged me in a lively discussion of the terms "average" and "mean" as they relate to your monthly calculations. Indeed, statistically they are different. I have noticed that a couple of you have, in particular, maximum temperature "averages" considerably higher than surrounding weather sites, official and unofficial. Two conclusions came out of our email discussions. The first is that a few of you may actually be computing the "mean maximum temperature", which is indeed not the same as the "average maximum temperature". The second is that my forms updated last year and based on those of previous years actually ask for the "mean" maximum, minimum, and monthly temperatures which is not, as Albert discovered, what our ACON group actually wants to archive. Instead, we want the "average" maximum, minimum, monthly temperatures AND, most importantly, that's what most of you have been reporting 'lo these many years (1995 - we're ten years old online in October!) So, I thank Albert for deducing this problem with our forms and I thank him for being very observant! Will attach the updated forms for you or can simply interchange the terms mean and averages on the form where appropriate!

Virginia:

Annandale - Lowell notes: " February was drier and warmer than average. The snowfall was 10.7 inches or 4.3 inches above the average. Last February had only 0.1 inches of frozen precipitation occurring as sleet. This is the most snow in February since 2003 when the 30.9 inches occurred setting the 25 year record. The 2.05 inches of precipitation for February was a departure of - 0.99 inches from the average. This was the least precipitation for February since 2002. The mean temperature departure for the month was + 0.6 F. The lowest temperature was 16F on the 19th. The highest maximum temperature in February was 64F on the 16th that set the 25-year record high maximum temperature for the date. February had 19 days with the minimum temperature at or below freezing that is the least since 2002 that had 18 days. The 10.7 inches of snow in February was the sixth snowiest February in the last 26 Februarys and the 5.0 inches of snow on the 24th was the tenth largest snow in February in the last 25-years and a 25-year record snowfall for the date. The maximum gust of 41 mph from the WNW on the 10th at 1700 was the strongest wind gust recorded for the month. The minimum barometer reading of 29.54 inches on the 28th was the highest minimum barometer recorded in February since 2002 when 29.59 inches was recorded. The winter season's (Dec. - Feb.) precipitation was 8.91 inches a departure of only -0.39 inches and was the eleventh driest winter in the past 26 winters. Average is 9.30 inches with 15.74 inches as the extreme maximum and 3.63 inches as the extreme minimum. The winter season's (Dec. - Feb.) mean temperature was 37.0 the departure of + 0.6 F and was the tenth warmest of the past 26-winters. Average is 36.4 F with 41.8 F the extreme maximum and 31.7 F as the 26-year minimum. Only 7 February DAILY Records Tied or Broken- (25-Years of records): 2 HIGH maximum temperature:7,8; 2 LOW range temperature: 24, 28; 1 HIGH precipitation: 24; 2 HIGH snowfall: 24, 28. " [ + - ] 

Arlington - NWS LWX's Strong reports: " NO NEW RECORDS WERE SET AT WASHINGTON NATIONAL AIRPORT IN FEBRUARY. SUMMARY... FEBRUARY 2004 WAS RATHER TYPICAL. AFTER A DRY START...THERE WERE SEVERAL WEAK TO MODERATE STORMS THAT AFFECTED THE REGION DURING THE LATTER HALF OF THE MONTH. ALTHOUGH PRECIPITATION WAS ABOUT AN INCH BELOW NORMAL...SNOWFALL ENDED UP BEING NEAR NORMAL. TEMPERATURES WERE SLIGHTLY WARMER THAN NORMAL...MAINLY THANKS TO TWO BRIEF WARM SPELLS IN EARLY AND MID MONTH. THERE WERE TWO MODERATE WINTER STORMS ON THE 24TH AND 28TH THAT PRODUCED NEARLY ALL OF THE SNOW IN FEBRUARY...JUST OVER FIVE INCHES. ALTHOUGH THERE WERE SEVERAL INCHES OF SNOW WITH THESE...NEGATIVE EFFECTS WERE LIMITED. TEMPERATURES NEAR FREEZING DURING BOTH EVENTS MELTED MUCH OF THE SNOW THAT TRIED TO ACCUMULATE ON AREA ROADS. " - [ + - ] "

Bridgewater - " The average temperature for the month was 3.36 degrees above normal. The precipitation was .83 inches below normal. Precipitation for the year is now 2.81 inches which is 2.06 inches below normal. Snowfall was a little above normal, thanks to the 5.5 inches which fell on the last day of the month. This was the biggest snow for this area so far this year. Places east of here have had more snow than we have had here in the mountains which is a little unusual. The Eastern Shore of Maryland and Delaware have had more. April 15 is my cutoff day for anymore measurable snow. . In my 40 years or so of record-keeping on snow, I haven't had a measurable snow past this date. " - [ + - ] 

Centreville - " While prognosticator Punxsutawney Phil predicted more winter ahead, perhaps Phebruary temperatures were excluded from his prophecies when he calculated those conditions. The monthly mean of 38.3 came in 4.4 above the 33.9 normal average. The overall warmth was helped along by two days with a high temperature of 63 which was also our monthly maximum reading. There were a total of six days when highs were 60 or greater. With one of the 63 days happening on the 15th, four days later on the 19th was when the lowest temperature for February was recorded; 16. Only two other days gave us temperatures in the teens; the 1st and 2nd with a pair of 17 mornings. The average monthly minimum of 29.8 for February came in at a bone-chilling 0.3 below the previous month and was 5.6 above the 23.3 average nightly low expected for the month. Water from melted snow was our principal source of moisture for February with 1.12" melted from 11.4" of snowfall for the month in three snow events. Rain accounted for 0.83" yielding a precipitation total for February of 1.95" when combined the water equivalent of snow. While not a remarkable feat in itself, 0.42" of rain fell on the 15th and produced over 50% of our unremarkable monthly rain total. A rainfall deficit of 0.98" this month combines with January for an annual shortage of 1.32"; or 80% of normal for 2005. " - [ + - ]

Falls Church - " February 2005 was a pretty average month except for snowfall which was an inch above average for my area. My biggest snowfall occurred on the 24th, which brought 4 inches. Strong winds on the 18th brought a number of large branches down in my yard. " - report from Erica   [ +/- +/- ]

Hampton - Dave sends these notes: " Cold weather continues with only a couple of very mild days for the month. Little snow however with most moisture and cold weather not occuring together and all snow events have been north and west of the entire AKQ area. " - [ - - ]

Herndon - Bob reports:" My average MAX temperature was 0.2 ABOVE the Dulles "normal" and the average MIN was 3.9 ABOVE normal. " - [ + M ] 

Herndon - Russ reports:" February temperatures averaged above normal and precipitation was below normal. The monthly temperature was 1.9 degrees above normal and precipitation was 0.94" below average. Snowfall was actually above average, with 10.5" total falling on the 3rd (1.0"), 24th (4.5"), 25th (Trace), and 28th (5.0", new record). Freezing rain fell on the 28th, when the snow briefly changed over and then back. This winter was marked by the extremes in temperatures and the lack of any significant winter storms (although several were forecast). " - [ + - ] 

Portsmouth - " February 2005 station records: 3RD DAILY PRECIPITATION 0.69" [PREVIOUSLY 0.58" 1988]; 8TH DAILY MAXIMUM TEMPERATURE 69 [PREVIOUSLY 66 1994] 28TH DAILY PRECIPITATION 0.80" [PREVIOUSLY 0.49" 1997] Precipitation was below normal for the month (84%) and temps (+0.5) were above normal. - [ + - ] 

Ruther Glen - Danny sends these notes: " February was a month of ups and downs, with two distinct warm periods in the middle of the month interspersed with very cold temperatures. Winter attempted to make its presence known, with two events at the end of the month bringing 3.3" of total snowfall. Areas to the north and west of my Caroline County location received much more snowfall, however. Another month of below average precipitation puts our 2005 rainfall deficit at 1.8". " - [ + - ]

North Carolina:

Raleigh - " Uneventful month with no snowfall nor ice observed. Precipitation was 1.02" below normal and the year to date deficit now stands at 2.25". The average daily temperature was 0.8 degrees above normal. " - report from Bob [ + - ] 

Raleigh - NWS Raleigh (RAH) reports: Here is an overview from the climate summary from NWS RAH: " February 2005 continued the 2004-2005 winter season trends of greatly fluctuating temperatures along with below normal precipitation. Much like January 2005, the first half of February averaged warm and dry but the month would end cold and wet. There was little in the way of storminess, except for a glancing blow of winter weather on February 3. It would not be until the final week of February that North Carolina would receive significant precipitation from two late winter storm systems that boosted monthly precipitation totals to just less than critical deficits.
