  • FLASHBACK: AUGUST 6th, 1993 TORNADO OUTBREAK IN SOUTHEASTERN VIRGINIA | RUTGERS UNIVERSITY GLOBAL SNOW LAB    ACON MD/DE/DC Member Kevin Shaw sends this retrospect: "You may have already seen this, but an article on the WTKR website (Norfolk, Virginia) posted about the 20th anniversary of the big Southeastern Virginia tornado outbreak in 1993: http://wtkr.com/2013/08/05/tuesday-marks-20th-anniversary-of-se-va-tornado-outbreak/  "

    And here's a link Kevin sends on the Global Snow Lab at Rutgers University: http://climate.rutgers.edu/snowcover/



  • RAINFALL IS VARIABLE - (from CoCoRaHS)      We know from our CoCoRaHS observations that precipitation is distributed very unevenly across our network. If we look across the globe, we find that the variability is even greater. According to the US Geological Survey, Mt. Waialeale, Hawaii holds the world's record for average-annual rainfall. "Mt. Waialeale averages about 450 inches (1,140 cm) per year. A remarkable 642 inches (1,630 cm) was reported there during one twelve-month period (that's almost 2 inches (5 cm) every day!). Is this the world record for the most rain in a year? No, that was recorded at Cherrapunji, India, where it rained 905 inches (2,300 cm) in 1861. Contrast those excessive precipitation amounts to Arica, Chile, where no rain fell for 14 years, and in Bagdad, California, where precipitation was absent for 767 consecutive days from October 1912 to November 1914."

    Arlington/Washington, D.C. - " THE MONTHLY AVERAGE TEMPERATURE THIS AUGUST WAS SLIGHTLY BELOW NORMAL. IT WAS THE FIRST COLDER THAN NORMAL AUGUST SINCE 2008 AND THE FIRST COLDER THAN NORMAL SUMMER MONTH SINCE JULY 2009. THE DAILY MAXIMUM TEMPERATURE ONLY REACHED OR EXCEEDED 90 DEGREES SIX TIMES IN WASHINGTON THIS AUGUST...WHICH WAS THE LEAST NUMBER OF 90-DEGREE DAYS IN AUGUST SINCE 2004. THE MAXIMUM TEMPERATURE NEVER REACHED 95 DEGREES DURING THE ENTIRE MONTH. 2013 WAS ONLY THE SECOND YEAR SINCE 2005 WITH NO 95-DEGREE DAYS RECORDED IN AUGUST. THERE WERE THREE DAYS THIS MONTH WHERE THE TEMPERATURE FAILED TO RISE ABOVE 75 DEGREES...WHICH WAS TIED WITH 1996 AND 2007 FOR THE MOST SUCH DAYS IN AUGUST IN THE PAST 20 YEARS. THE HIGH TEMPERATURE OF 74 DEGREES ON THE 6TH TIED 1886...1993 AND 2004 FOR THE DAILY RECORD LOW MAXIMUM TEMPERATURE. THIS AUGUST WAS DRIER THAN NORMAL WITH WASHINGTON RECEIVING LESS THAN HALF OF ITS NORMAL MONTHLY RAINFALL. AUGUST 2013 WAS ONLY THE SECOND AUGUST IN THE LAST 15 YEARS THAT DID NOT RECORD AT LEAST A HALF-INCH OF RAINFALL ON ANY CALENDAR DAYS. " - [ - - ] - from NWS Sterling, VA

    Chantilly - from Russ Topping: " August was cooler and drier than normal. The mean monthly temperature was 74.8 (-0.6). The mean high temperature was 83.9 (-2.7) and the mean low temperature was 65.6 (+1.4). A record low high temp was set on the 18th (71). A record high minimum temp was set on the 9th (75). This was the coolest August at this site in five years. We barely cracked the 90 mark six times. August rainfall totaled only 2.04", half of which was received on the 13th. Thunderstorms were observed on the 21st. Thunder also occurred on the 3rd and 13th. Dense fog was observed on the 12th and 20th. *Please note, anemometer is currently partially obstructed from the North and East " - [ - - ]

    Dulles - from NWS Sterling (KLWX): " THE MONTHLY AVERAGE TEMPERATURE THIS AUGUST WAS SLIGHTLY BELOW NORMAL. IT WAS THE FIRST COLDER THAN NORMAL AUGUST SINCE 2008 AND THE FIRST COLDER THAN NORMAL SUMMER MONTH SINCE JULY 2009. THE MAXIMUM TEMPERATURE REACHED 90 DEGREES TWICE THIS MONTH...BUT DID NOT EXCEED 90 DEGREES. AUGUST 2013 WAS ONLY THE THIRD AUGUST ON RECORD WITH NO DAYS ABOVE 90 DEGREES AT DULLES (1969 AND 1974 WERE THE OTHER YEARS). A DAILY RECORD HIGH MINIMUM TEMPERATURE OF 75 DEGREES WAS SET ON THE 9TH...BREAKING THE PREVIOUS RECORD OF 74 DEGREES IN 2007. THE MAXIMUM TEMPERATURE OF 72F ON THE 18TH WAS THE COLDEST AUGUST HIGH AT DULLES SINCE 28 AUGUST 2008 (71F). THIS AUGUST WAS DRIER THAN NORMAL WITH DULLES ONLY RECEIVING ABOUT HALF OF ITS NORMAL MONTHLY RAINFALL. " - [ - - ]

    Glen Allen - from Lowell Koontz: " August was far from the norm as it was the coolest, cloudiest and most humid, most days with rain and the second wettest in the past five years. The monthly mean temperature was 74.6 F, a -3.7 F mean temperature departure based on a five-year average. The 6.20 inches of rain for August was a +1.38 inch departure based on a five-year average and the second wettest August on record. The most intense rainfall records were broken on the 10th when 0.16 inches fell in one minute, 0.67 inches in 5 minutes, and 1.07 inches occurred in 15 minutes. Precipitation occurred on 14 days, the greatest number of days on record for August. The maximum temperature for August was only 92F on the 9th. On 4 days the maximum temperature was greater than or equal to 90 F; this is the lowest number for August. The lowest minimum was only 56 F recorded on the 16th and 26th and both were new records for Glen Allen. The lowest maximum was 68 F on the 18th; the previous low was 70 F set in 2008. The maximum wind gust was 37 mph from the NNW that occurred on the 10th at 1337 hours. Before drawing too many conclusions between these tables, note Glen Allen has a five-year average and the Richmond International Airport uses a 30-year average. This summer was much cooler than the past five years some of which have been record breaking for heat like 2010 and 2011. This summer was more humid at the Glen Allen Station than any of the past five years by 7.2 percent. June, July, and August all set new high relative humidity records. Note July had a +9 percent departure; this explains why my tomatoes did so poorly and the Septoria (a fungus disease) had its way with my tomatoes. It was the worst tomato crop in my past five years in Glen Allen.

    Herndon - from Randy Ashby: " August was below normal for temperature and precipitation. The temperatures ranged between a high of 89 and a low of 52. On the precipitation side, the month was 2.17 above below normal. It rained on 12 days during the month, but most of the amounts were very light. We are now only 0.34 above normal for the year. " - [ - - ]

    Portsmouth - from Bill Trotter: " August's average temperature of 76.2 was 2.0 BELOW NORMAL. Precipitation (5.88") was ABOVE NORMAL by 0.18" or 103% of the normal August average during the period from 1976 to 2012. Rainfall for the year-to-date through August 31st was 35.90" (+2.05") and 106% of normal. Frontal passages were observed on the 1st, 4th, 11th, 14th, 23rd, and 29th. STATION RECORDS: 11th - WIND GUST 45mph [previously 34mph 1992], 17th - TEMPERATURE Minimum High 76 [76 1981], 25th - TEMPERATURE Minimum High 77 [ 78 1977]. - [ - + ]

    Richmond - from contributor Lowell Koontz (GAV): " The Richmond International Airport (KRIC) had 7.72 inches of rain for August; only 27 years have had a wetter August in the past 141 years. It was the greatest rainfall total for August since 2004, which holds the August record rainfall total of 16.30 inches. The Richmond International Airport had an August mean temperature of 75.9 F the coolest since 2004 which was also the wettest August on record because of the remnants of Hurricane Gaston. In the past 116 years, only 51 Augusts have been cooler. The Richmond International Airport tied only one record for the date. On Aug. 18th, the lowest maximum temperature for the date was 70 F set in 1918, which was tied, and only 24 years of the past 116 have had a lower August temperature. The Richmond International Airport also set a new low temperature range record on the 18th of 4 F; the previous record was 5 F in 1989. In the past 116 years only 3 days in August have had a lower temperature range than 4F, which occurred in 1971, 1996, and 1956. In the past 116 years only 26 Augusts have had a lower average maximum temperature. The August highest maximum was 93 F on the 9th and only 17 years have had lower maximum temperature since 1897. Augusts lowest minimum temperature was 57 F on the 26th, which was the lowest August temperature since August 7, 2004. Richmond had 0.35 inches more rainfall than Glen Allen for the summer and Richmond International Airport temperatures averaged 1.3 F more than Glen Allen for the summer. If one averages the mean temperatures for the Airport for the past five years the average is 79.0 F.
