THE SECOND HALF OF THE MONTH FEATURED TYPICAL MARCH WEATHER. A WEEK OF RELATIVE SPRING WARMTH...15TH THROUGH 23RD...WAS FOLLOWED ON THE 24RD THROUGH THE 31ST BY PERSISTENTLY COLD CONDITIONS...MORE TYPICAL OF FEBRUARY. SEVEN DAYS WITHIN THIS EIGHT-DAY STRETCH BETWEEN 24-31 MARCH FAILED TO REACH 50F. ONLY MARCH 1883 HAD THIS FREQUENT NUMBER OF DAYS BELOW 50F DURING THE 24-31 MARCH PERIOD SINCE OFFICIAL RECORDS BEGAN AT WASHINGTON DC. THE HIGH TEMPERATURE OF 80F ON 18 MARCH WAS THE FIRST TIME THE TEMPERATURE REACHED 80F IN MARCH SINCE 27 MARCH 2007. WASHINGTON DC RECEIVED ABOVE NORMAL PRECIPITATION IN MARCH FOR THE FIRST MONTH SINCE OCTOBER 2010. IT WAS THE WETTEST MARCH SINCE 2005. TWO-THIRDS OF THE PRECIPITATION FOR THIS MARCH WAS OBSERVED ON THE 6TH AND 10TH WHEN TWO SEPARATE STORM SYSTEMS EACH PRODUCED ALMOST ONE AND ONE-HALF INCHES OF RAINFALL. MARCH ALMOST FEATURED NO MEASURABLE SNOWFALL FOR THE SECOND STRAIGHT YEAR. HOWEVER...0.2 INCHES OF SNOW WAS RECORDED ON THE 27TH. " - [ - + ] - Notes from NWS Sterling, VA

    Bridgewater - " The temperature and precipitation were above normal. The snow on the 27th was beautiful . However, it melted quickly on the following day. My cut-off for any measurable snow is April 15. According to my 50 years of keeping records, we have had only 3 snows in April. My latest snow occurred on April 13. We have had flurries after this date, but no measurable snow. There is very little chance of snow this April. " - [ + + ] - additional notes from Clayton

    Chantilly - Russ adds: " March was the usual temperature roller coaster. Temperatures ended up averaging 1.1 above normal. Precipitation was 2.15" above normal, primarily due to the record setting extreme rain event on the 6th (2.67"). Snowfall was 3.3" below normal, with 0.1" on the 27th and a trace on the 6th. Sleet occurred on the 30th. Thunder was observed on the 21st and 23rd. We took to basements on the 10th, with a tornado warning for a confirmed tornado within 5 miles of this station. *Please note, anemometer is currently partially obstructed from the North and East " - [ + + ]

    Dulles - from NWS Sterling (KLWX): " ALTHOUGH TEMPERATURES AVERAGED NEAR NORMAL...MARCH FEATURED LARGE SWINGS IN TEMPERATURES FROM WEEK TO WEEK AND DAY TO DAY...CONDITIONS COMMON DURING THE SPRING. 13 OF THE 31 DAYS AVERAGED BELOW NORMAL. THE SECOND HALF OF THE MONTH IN PARTICULAR FEATURED A WEEK OF LATE SPRING WARMTH FOLLOWED BY COLD CONDITIONS DURING THE LAST EIGHT DAYS OF THE MONTH MORE TYPICAL OF FEBRUARY. SEVEN DAYS WITHIN THE EIGHT-DAY STRETCH BETWEEN 24-31 MARCH FAILED TO REACH 50F...WHICH IS THE MOST NUMBER OF DAYS BELOW 50F DURING THE 24-31 MARCH PERIOD SINCE OFFICIAL RECORDS BEGAN AT DULLES. THE HIGH TEMPERATURE OF 79F ON 18 MARCH WAS THE WARMEST MARCH READING SINCE THE TEMPERATURE REACHED 83F ON 27 MARCH 2007. MARCH WAS WETTER THAN NORMAL AT DULLES FOR THE FIRST MONTH SINCE SEPTEMBER 2010. IT WAS THE 6TH WETTEST MARCH ON RECORD AND THE WETTEST MARCH SINCE 1998 WHEN 5.60 INCHES OF PRECIPITATION FELL. A TOTAL OF 3.81 INCHES OF RAIN FELL DURING THE FIVE-DAY STRETCH FROM 6-10 MARCH 2011...WHICH IS THE MOST PRECIPITATION MEASURED AT DULLES DURING A 5-DAY PERIOD IN ASTRONOMICAL WINTER (21 DECEMBER-20 MARCH). THREE-FOURTHS OF THE PRECIPITATION FOR THE MONTH WAS OBSERVED ON THE 6TH AND 10TH WHEN TWO STORM SYSTEMS COMBINED FOR OVER THREE AND HALF INCHES OF RAINFALL. BOTH DAYS ALSO SET DAILY RAINFALL RECORDS. THE 2.30 INCHES OF RAINFALL ON THE 6TH BROKE THE OLD DAILY RECORD OF 1.12 INCHES SET IN 1967.

    Glen Allen - Lowell Koontz sends these additional notes: " March was warmer than average as the monthly mean temperature was 48.1F, a + 1.3F departure, and was also wetter than average (when compared to Ashland, Virginia records). The 4.24 inches of rain for March was a + 0.49 inch departure when compared to the Ashland, Virginia average. The maximum rainfall recorded in a day was 1.40 inches on the 10th. The total snowfall was only 0.2 inches for the month recorded on the 27th which was a -1.5 inch departure compared to Ashland records. Mid-March this year was warmer than average and the end was much colder giving a near average result and less snowfall than average and also the least in the past 3 years. The most unusual event in March was the hail near sunrise on the 21st. A thunderstorm passed the Glen Allen station around 0710 to 0720 AM giving about two minutes of hail from 0712 to 0714 A.M. (+/- 3 mins.) and gave only 0.04 inches of rain and 0.07 inches with the melted hail. The smallest hail was 0.25 inches and the largest was 0.5 inches but most averaged about 3/8 inch. It was interesting to have hail with almost most no wind or rain and the precipitation starting as hail and rain and also occurring around sunrise. The hailstone consistency was white ice but some hail had a band or layer of clear ice running through it and were irregular shaped and spheres. Richmond International Airport's March mean temperature of 48.7F was the 50th warmest of the past 115 years and the precipitation of 4.28 inches was the 32nd wettest in the past 115 years. The Airport had two records: 84F on the 18th ; the old record was 83F in 1927 and the 5F low temperature range tied the old record set in 1985 and 1961. There were 9 days the minimum temperature dropped below freezing. The maximum temperature for March was 82F on the 18th at this station. The lowest minimum was 28F recorded at this station on the 4th, 8th, 28th, 29th. A very low relative humidity of 14% was recorded here on the 11th. The maximum wind gust of 37 mph from the NNE occurred on the 6th at 1955 hours. March was also the third windiest month at this station with a total wind run of 1825 miles. The highest barometer recorded for the month was 30.63 inches on the 3rd and 4th which was the highest this station has recorded in March and the highest barometric pressure since December 12, 2009 when the pressure was also 30.63 inches of mercury. The lowest barometric pressure was 29.37 inches on the 23rd. " - [ + + ] 

    Herndon - Randy reports: " March was near normal for temperature and above normal for precipitation. The temperatures ranged between a high of 79 and a low of 25. The average highs/lows were 1.6 below and 0.8 degrees above normal, respectively. On the precipitation side, the month was 2.51" above normal with 5.36" measured. Rain fell off and on for most of the month, but the heaviest rains (4.10") came between the 6th and 10th of the month. With colder air moving into the area towards the end of the month, we ended up seeing some light snow and sleet on the 27th and 30th. But this month, the total amount of sleet and snow was only 0.3" and the warm weather, melted it quickly. We have now had 14.5" of snow for the season. " - [ + + ]

    Portsmouth - " March's average temperature (48.6) was 1.5 BELOW NORMAL. Rainfall was ABOVE NORMAL by 0.23" and was 106% of normal relative to normal Marchs for the period from 1976 to 2010. The seasonal snowfall increased by a trace on the 23rd. Frost occurred on the 1st, 2nd, 4th, 28th, 29th.
