  • DANNY JESSEE'S LADYSMITH, VIRGINIA STATION (LDY) ENDS DATA COLLECTION   Danny Jessee sends notice that he's moving to Alexandria! "Please note this will be my final month of submitting observations from Ladysmith. I am moving to a condo in Alexandria, VA in September. I don't know yet what the rules will be with respect to weather stations or if I will even be able to mount one appropriately to get accurate readings. I will keep you posted. If I am unable, it has been a pleasure working with you and being part of ACON these past few years. I'll definitely keep in touch." We certainly hope Danny can work something out with the homeowner's association and look forward to his return. Will be nice to have a station in Alexandria-

  • "WEATHER" NOW ON GOOGLE EARTH    From time to time, CoCoRaHS tries to make our observers aware of interesting climate and weather web sites that are out on the Web. It was recently brought to our attention that Google Earth is now offering weather as part of their new Google Earth 5.2. It's pretty cool. To quote from their web site: "It's the middle of summer, but for those of us who long for the return of cold winter weather and warm cups of cocoa, throw on your favorite poncho and check out the weather in Google Earth 5.2. The latest version projects images of rain and snow over the areas with those weather patterns as its actually happening! First enable the clouds layer, then zoom in to a particular location where it might be raining or snowing. Im willing to bet London is a likely spot, even these days, or the Lone Star state which is in the midst of tropical storm season. Currently, our precipitation data cover some areas in North America and Europe; you can see if its available in certain places by enabling the radar layer." To find out more on how you can download a free version of this product, visit their web site by clicking here: Google Earth - http://earth.google.com/ You'll also want to check out their blog post on this weather feature: Google Blog Post at http://google-latlong.blogspot.com/2010/07/rain-or-snow-now-you-can-see-weather-in.html   


  • NOAA's STORM PREDICTION CENTER (SPC)    Severe weather can occur year-round. NOAA's Storm Prediction Center (SPC) monitors potential severe weather situations across the country and helps to give both the citizens and forecasters in your area a heads-up of the potential of hazardous weather situations. The Storm Prediction Center's mission is to provide timely and accurate forecasts and watches for severe thunderstorms and tornadoes over the contiguous United States. The SPC also monitors heavy rain, heavy snow, and fire weather events across the U.S. and issues specific products for those hazards.

    Arlington - " TEMPERATURES THIS AUGUST WERE ONCE AGAIN ABOVE NORMAL FOR THE SIXTH STRAIGHT MONTH. THE MONTHLY AVERAGE TEMPERATURE OF 80.1F TIED WITH AUGUST 2005 AS THE 9TH WARMEST AUGUST OF ALL TIME...WITH AUGUST 1980 STILL THE WARMEST AUGUST ON RECORD IN WASHINGTON...AT 82.8F.

ON THE 11TH...A NEW DAILY HIGH MINIMUM TEMPERATURE RECORD OF 80F WAS SET...THAT BROKE THE PREVIOUS DAILY RECORD OF 78F IN 1988. ALSO...THIS IS THE FIRST TIME ON RECORD SINCE 1872...THAT THE MINIMUM TEMPERATURE IN WASHINGTON HAS NOT FALLEN BELOW 66F DEG. AUGUST WAS DRIER THAN NORMAL. FOUR OUT OF THE LAST FIVE MONTHS HAVE FEATURED BELOW NORMAL PRECIPITATION. A 59 MPH WIND GUST WAS RECORDED ON AUGUST 5TH WHEN A SEVERE THUNDERSTORM ACROSS THE AIRPORT. " - [ + - ] - Notes from NWS Sterling, VA

    Bridgewater - " The average temperature was 2.48 degrees above normal while the precipitation was .75 inches below normal. Precipitation for the year now is 20.97 inches, which is 4.40 below normal. There were two thunderstorms during the month. Thunderstorms for the year are much below normal. In Bridgewater, there hasn't been a severe thunderstorm all year. " - [ + - ] - additional notes from Clayton

    Centreville - Paul adds : " Seems like August 5th was the busiest day in data logging history for quite some time. Max temp, peak wind Gust, max daily precip., and minimum barometric pressure all occurred on that Thursday in sunny Centreville, home of the not yet famous jet ski and snow blow invitational. - [ + + ]

    Chantilly - Notes from Russ: " August temperatures averaged 1.9 above normal and precipitation was 1.79" above normal. A record high minimum temperature occurred on the 4th (73.5) and 22nd (73.3 tie). Record daily rainfall occurred on the 5th (1.97") and 18th (1.29"). Thunderstorms occurred on the 5th, 13th, and 18th, providing for most of the August precipitation. Please note, anemometer is currently partially obstructed from the Southeast " - [ + + ]

    Dulles - from NWS Sterling (KLWX): " TEMPERATURES THIS AUGUST WERE ONCE AGAIN ABOVE NORMAL FOR THE SIXTH STRAIGHT MONTH. THE HIGH OF 97F ON THE 11TH BROKE THE PREVIOUS DAILY HIGH RECORD OF 96F SET IN 1980. A DAILY HIGH MINIMUM TEMPERATURE OF 73F ON THE 4TH BROKE THE PREVIOUS RECORD OF 72F IN 1988 AND 2006. THERE WERE 12 DAYS OF 90F DEGREES OR BETTER THIS MONTH. AUGUST WAS WETTER THAN NORMAL. OVER AN INCH OF RAIN WAS MEASURED ON THREE SEPARATE CALENDAR DAYS THIS MONTH...AUG 5TH...12TH AND 18TH... FOR ONLY THE THIRD TIME ON RECORD IN THE MONTH OF AUGUST AND THE FIRST AUGUST SINCE 1968. A DAILY RAINFALL RECORD WAS SET ON THE 18TH...THE 1.39 INCHES OF RAINFALL THAT DAY BROKE THE OLD DAILY RECORD OF 0.89 IN 1965. " - [ + + ]

    Glen Allen - Lowell Koontz reports: " August was very hot, the only months that were hotter were June and July of this year although August of last year was nearly as hot. But as West Henrico Co. - Glen Allen station only opened in August of 2008 we use the Airport for historic records. Using the mean temperatures for the Richmond International Airport, this August was the seventh hottest of the 113 years of records and August 2009 was in eighth place. The month's average temperature here was 77.4F a +4.2F departure when compared to Ashland's average and only 0.1F warmer here when compared to last August. The 3.97 inches of rainfall for August was only 0.11 inch less than average when compared to Ashland's average. The West Henrico Co. - Glen Allen Station had thunder on 8 days but several thunderstorms went to the SW or south. August had more humidity than July. The average relative humidity for July was 63.5 % and for August 72.7 % thus the heat was felt more. On the 5th after rain just before midnight of the 4th, the morning broke hot and steamy. The Davis Pro recorded a high dew point of 80.4F at 1355 and a heat index of 115.7F. I think these values might be as much as 2F high but at any rate it is the highest I have ever seen displayed on the Davis Pro 2. August had 12 days with measurable rain with 1.19 inches of rain that occurred on the 12th in a thunderstorm, which was about 30% of the month's rain. August had 16 days with 90F or above temperatures and the Airport had 17 days. The maximum temperature for August was 97F recorded on August 10th, 11th, and 30th and the lowest minimum temperature for the month was only 66F. This is a very high minimum temperature for the month. A wind gust of 33 mph that was recorded on the 5th occurred at 1725 during a thunderstorm and was the strongest wind gust recorded for August. On the 7th I wired in a new anemometer that is now approximately 45 feet above the ground and should improve my wind observations. The summer was the hottest summer Richmond has ever experienced. The summer season average was 1.7F hotter than the previous summer season record of 79.6F set in the summer of 1900. The West Henrico Co. - Glen Allen station had a summer season average of 80.5F and the Richmond International Airport had 81.3F or +0.8F hotter than western Henrico. The summer was the driest on the West Henrico Co. - Glen Allen VA Station records but still wetter than Richmond by 3.52 inches. The summer for Richmond was the third driest in the 113 years of records. " - [ + - ] 

    Herndon - Randy sends these additional notes: " July was above normal for temperature and well above normal for precipitation. The temperatures ranged between a high of 99 and a low of 53. The average highs and lows were about 2.5 and 0.5 degrees above normal, respectively. We recorded 20 days where the max temp was 90 or higher. On the precipitation side, the month was 2.76" above normal with 6.49" measured, the most I have recorded in July in the last 17 years. From the 10th through the 19th, there were many days with scattered thunderstorms where some areas got lots of rain and others got little. My site was one of those that was very wet. The last 10 days of the month also saw a couple of days with TSRA; especially on the 25th when some severe TSRA went through the area producing some heavy rains and very strong winds. Fortunately, the worst winds occurred just north of my station. We have now had 24.07" precipitation for the year that is still over 2.75" below normal. " - [ + + ]

    Ladysmith - Danny adds: " August brought a return of more "normal" temperatures (only 10 days above 90 in August, compared to 23 in July) and precipitation (first month with above normal rainfall since March). Please note this will be my final month of submitting observations. " - [ + + ]

    Norfolk & Richmond - from NWS AKQ: " WARMEST SUMMER ON RECORD AT RICHMOND...3RD DRIEST SUMMER ON RECORD AT RICHMOND...
