SUMMARY OF CLIMATOLOGICAL DATA 
JULY 2004

...ABOVE AVERAGE NUMBER OF THUNDERSTORMS
PROVIDE CONSIDERABLE RAINFALL FOR MANY...

The one data category from your reports that stands out the most is the high number of thunderstorm days across the region in July 2004. Lots of downpours noted, typical in mid-summertime. However, a look at the data and the negative rainfall departures for several indicates that quite a few of us were bypassed. Highest rainfall amounts are clearly seen over Southeastern Virginia and the lower DelMarVa Peninsula with two days having training thunderstorms which helped push monthly totals well above 10 inches! Below normal rainfall noted for the mountains of Virginia and, surprisingly, Eastern North Carolina. Seems the rainfall corridor was from central South Carolina through central North Carolina, and over the aforementioned Southeastern Virginia and the Virginia Eastern Shore.

With the plentiful rainfall in many areas, temperature averages were held down in quite a few locales. In all three states, near normal averages noted with a few exceptions.

High pressure centers repeatedly dominated the area from offshore Southeast US and the winds on their backsides funneled abundant moisture north-northeast across those areas mentioned earlier.

  • CLOUD STAMPS    In a recent email from former group member Eleanor Talbot, she writes: " As many of you have heard, the United States Postal Service has finally published a series of stamps called Cloudscapes. A group of 15 stamps, in order of height, will premier on Monday, October 4th, at a First Day of Issue ceremony that will be held at no other place than the Blue Hill Observatory in Milton, Massachusetts! The Observatory will be expanding the festivities throughout the entire weekend, including an Open House on Saturday, October 2nd, and a Kite Building and Flying day for kids on the 3rd before the First Day of Issue ceremony on Monday. For all the details, check out the Blue Hill website at http://www.bluehill.org and look for "upcoming events." For more details about the cloud stamps themselves, the NWS office in Memphis has each one on their webpage. Here's the link: http://www.srh.noaa.gov/meg/Stamps/stamps.html " Thanks Eleanor!


  • DROUGHT MONITOR    Looks like most of the area is out of the dry spell at this time (end of July). For the latest U.S. Drought Monitor graphic, visit http://www.drought.unl.edu/dm/monitor.html.


  • U.S. DAILY WEATHER MAPS PROJECT   Looking for that NOAA Daily Weather Map for a given date since 1871? Look no further! Visit the NOAA Central Library U.S. Daily Weather Maps Project [1871-2001] at http://docs.lib.noaa.gov/rescue/dwm/data_rescue_daily_weather_maps.html. A link to maps for 2002 to the present is found at the top of the page. Great resource! Note: You will need to download and install a small program in order to view the maps.
  • STATIONS MAPS   Ever wonder just where Clayton's station in Bridgewater, Virginia is located or where are Hampton (Dave) and Herndon (Russ), also in Virginia? Or just where is Bob's site in Raleigh or Bob's site in Brevard, North Carolina? And, let's see, where is Joyce in New Market, VA? And is Tri-Cities really in TN or VA or both? An Internet link to MapQuest.com depicting the general area of our region in which you are located is now available with a click to your station ID in the STATION / LOCATION table found at the end of this report. And with MapQuest, you can zoom in and out to get a better idea of where we are all located within the entire region. None of your specific street addresses was used; simply the general area in which you're located is depicted.

Virginia:

Annandale - Lowell sends these notes: " July was a little below average in rainfall and near average in temperature with no really hot days although high humidity gave high dew point temperatures. July's mean average temperature (77.6F) was only - 0.1F departure. July had 11 days with measurable rain which was average but had a rainfall departure of - 0.81"inches. The rainfall totals over the area varied widely with some particularly high totals in NE Maryland. July's average sky cover makes it normally the clearest month of the year but this month was the cloudiest July on my records and the third cloudiest month of 2004 lowering the temperature ranges and reducing the number of equal to or greater than 90F days. July had only 9 days with 90F or above temperatures and in 2002 we had 20 days. Both July of 2003 and 2004 had a small number of equal to or greater than 90F days. This year had 16 days of equal to or greater than 90F and last year had but 12 days which was a record low number going back to 1992. Only one July in the last 24-years has the maximum temperature for July been less than 92F; that occurred in 2000 when 91F was the maximum for the month. The maximum temperature for 2004 is still 92F and is the first time in the last 24 years we have gone this long in the summer without a 93F or hotter day. The previous latest date was July 9, 1992. July's average temperature range was only 17.4F the least since 1996 except for last year and only four years have been lower in the last 24-years. The lowest daily temperature range for the month was only 4F that occurred on the 25th; the 24 year-record is 3F that occurred on July 13, 1989. The maximum wind gust for July was only 27 mph from the WNW on the 14th at 1500. July had only one daily temperature and precipitation record for the month which is the least recorded since these observations were started in November of 2001. The previous low record was four. Only 1 daily record was set! July DAILY Records Tied or Broken in 24 Years of records: Daily LOW range: 25th. " [ - +/- ] 

Arlington - NWS WBC reports: " RECORDS: ON THE 4TH...A RECORD DAILY RAINFALL OF 2.18 INCHES BROKE THE OLD RECORD OF 2.00 INCHES SET IN 1882. JULY 2004 FOLLOWED JUNE'S LEAD AS A WETTER AND SLIGHTLY COOLER THAN AVERAGE MONTH IN THE NATION'S CAPITAL. THE MOST DOMINANT CHARACTERISTIC OF THE MONTH WAS DAMPNESS. THAT ALLOWED THE AVERAGE HIGH TEMPERATURE TO BE TWO AND A HALF DEGREES COOLER THAN NORMAL WHILE THE NIGHT TIME LOWS WERE ACTUALLY MORE THAN A DEGREE WARMER THAN NORMAL. THE DAMPNESS OF COURSE ALSO ALLOWED FOR A RATHER CLOUDY AND RAINY MONTH BY JULY STANDARDS. LESS THAN A QUARTER OF THE DAYS HAD MORE SUN THAN CLOUDS...AND RAINFALL WAS CLOSE TO DOUBLE THE AVERAGE FOR JULY. THE NEARLY SEVEN INCHES OF RAIN THAT FELL WAS ENOUGH FOR THE 15TH WETTEST JULY ON RECORD...A FEAT EVEN MORE IMPRESSIVE WITH NO TROPICAL CYCLONES DURING JULY TO ADD TO OUR TOTAL. JULY 2004 ALSO PRODUCED THE WETTEST 4TH OF JULY ON RECORD...MORE THAN TWO INCHES ON THAT DAY ALONE. INTERESTINGLY...A SHORT WINDOW OF DRY WEATHER ON THE EVENING OF THE 4TH STILL ALLOWED MOST OF THE CELEBRATION ON THE NATIONAL MALL TO GO ON UNHINDERED. TWO DAYS IN JULY HAD MORE THAN TWO INCHES OF RAIN...THE 4TH AND THE 27TH. IT WAS THE WETTEST MONTH SINCE JUNE OF 2003. - [ - + ] "

Bridgewater - " The average temperature was .5 degrees above normal and the precipitation was 1.09 inches above normal. The precipitation for the year is about an inch above normal. There were numerous chances for thunderstorms during the month when nothing happened. At the time of this writing, it's getting a bit dry. This weather information is what I recorded at my location in south Bridgewater. Some nearby places had heavy rainfall in slow-moving thunderstorms, when Bridgewater received very little of anything. " - notes from Clayton [ + + ] 

Centreville - " With rain and temperature records well out of reach for this July, it is a comfort to report that the average daily high for the month of 86.8 was a slight tenth of a degree cooler than the 86.9 normal average high. The hottest we got was 93 on July 14th, so the 103 record high set 16 years ago remains as "top temp" for another year. Our mean monthly low of 69.3 came in at 6.1 above the 63.2 normal average low for the month. However, for the year, we have been averaging 4.9 above normal for our lows, so our July average monthly low maintains a comfortable position among its peers. Precipitation amounts for July in Centreville shouldn't have been the cause for much alarm when only 0.21" over the 3.57" average was recorded. With the spillways delivering at full volume, this staggering fifth-of-an-inch excess helped bring our annual rainfall deficit to less than four inches. The 3.78" total was tallied with 15 days of reportable rain for July, and included our greatest daily amount of 1.20" that fell just before noon on Independence Day. A nice contribution by Mother Nature to help maintain comfortable temperatures and produce clearing skies for the evening celebrations that were soon to follow. " - notes from Paul [ - + ] 

Herndon - Bob notes:" My average MAX temp was 3.4 BELOW the Dulles "normal" and the average MIN was 3.5 ABOVE. Dulles is about 4 miles WSW and its "normal" is the 1971-2000 average. " - [ + + ] 

Herndon - Russ reports:" July was cooler and wetter than normal. The monthly temperature was 1.2 below average and precipitation was 1.28" above average. Thunderstorms passed through on July 4th, 5th, 7th, 14th, 19th, 22nd and 23rd. The storms on July 4th pre-empted some of the man-made fireworks in our area with nature's. We haven't watered the lawn once! " - [ - + ] 

Lexington - Scott reports: " Reminder: It's hurricane season and the WREL HurricaneCenter is up and running! This site is primarily designed for the Mid-Atlantic and Southeast regions. We run computer model maps on all systems as well as provide inland and coastal information for this area. The address is: http://www.wrel.com/hurricane.htm. "

Norfolk - More interesting notes from Maloit and Brown at NWS AKQ: " THIS WAS THE 8TH WETTEST JULY ON RECORD AT NORFOLK WITH 10.89 INCHES OF RAINFALL. THE 10 WETTEST JULYS ON RECORD: 14.37 1994; 13.73 1975 ; 12.92 1945 ; 12.70 1969 ; 12.40 1939 ; 11.92 1922 ; 11.73 1917 ; 10.89 2004 ; 10.79 1950 ; 10.69 1889 . THIS WAS ALSO THE 8TH MOST NUMBER OF DAYS WITH MEASURABLE RAINFALL AT NORFOLK IN JULY (15 - TIE WITH 2003 AND OTHER YEARS). THE 10 MOST NUMBER OF DAYS WITH MEASURABLE RAINFALL IN JULY: 22 1917; 21 1889 ; 20 1945 ; 19 1994* ; 18 1906* ; 17 1985* ; 16 2000* ; 15 2004* ; 14 1991* ; 13 1996* . * Denotes other years. OTHER ITEMS OF INTEREST AT NORFOLK... 15.75 INCHES OF RAINFALL SO FAR THIS SUMMER ALREADY RANK THIS AS THE 56TH WETTEST SUMMER ON RECORD...ONLY NEED A SLIGHTLY BELOW AVERAGE AVERAGE AUGUST (4.74 INCHES - AVERAGE 4.79 INCHES) TO MAKE THIS ONE OF THE TOP 15 WETTEST SUMMERS ON RECORD...HOWEVER NEED AN ABOVE NORMAL 5.90 INCHES TO CRACK THE TOP 10. WITH AN AVERAGE TEMPERATURE OF 79.2 DEGREES THIS IS THE 28TH WARMEST JULY ON RECORD. THIS WAS DONE WITH A BELOW NORMAL NUMBER OF 90+ DEGREE DAYS (6 - 13 IS NORMAL FOR JULY)...BUT AN ABOVE NORMAL NUMBER OF NIGHTS WITH LOW TEMPERATURES OF 70+ DEGREES (27 - 22 IS NORMAL). FOR THIS SUMMER...NORFOLK IS ALREADY BELOW NORMAL FOR NUMBER OF 90+ DEGREE DAYS TO DATE (9 - 20 IS NORMAL FOR JUNE AND JULY). IT WOULD TAKE A RECORD NUMBER OF 90+ DAYS IN AUGUST (20 - 19 IS THE RECORD AND 9 IS NORMAL) JUST TO REACH THE NORMAL NUMBER OF 90+ DEGREE DAYS IN A SUMMER (29). "

Portsmouth - " Little change from June 2004...that strong onshore and SE flow resulted in abundant rains from the SE and S as Bermuda high pressure continued to funnel moisture north along the SE US and Mid-Altantic coasts. Rainfall measured 1.57" ABOVE normal (129%). The average temperature was 1 BELOW normal due to the above normal rainfall. Fog- of varying degrees - was noted on a whopping 21 of the 31 days, again no surprise considering the excess rainfall. That was 1 more day than the whopping high in June of 20! A quiet month for new records with one station record tied or broken: 16TH - TEMPERATURE - MINIMUM TIED 66 [PREVIOUSLY 1981]" - [ - + ] 

Mechanicsville - Glenn notes a... " A lot of t-storms during the month with very heavy showers. T-storms occuring on the 20th caused flood of low lying areas." "

Ruther Glen - Danny notes: " The streak of below normal precipitation months finally comes to an end with rainfall coming in a full three inches above normal, thanks to nearly four inches of rainfall on the 26th and 27th of the month. This month's precipitation erases nearly four months of rainfall deficits, but still leaves us below average for the year. An unseasonably cool stretch of weather toward the end of the month kept temperatures for the month slightly below normal. This is the second straight month of slightly below normal temperatures.

Roanoke - Wendell sends these notes:" Believe it or not, I just had my 4th driest July on record. Only 1983 with 0.98" and 1977 with 1.01" and 1998 with 1.47" were drier than the 2.04" this July. And so many areas nearby in Roanoke had very heavy rains. The average temperture of 75.8 was 0.2 below normal. Our dry spell is so hard to believe since so much of the State has had so much rain.

Raleigh - NWS Raleigh (RAH) reports: " Numerous thunderstorms in July brought bountiful rainfall to much of western and northern North Carolina, continuing the wet trend that began in June. Most reporting stations across the state received between 4 and 7 inches of rain. These totals were either near normal or above normal. The greatest monthly rainfall amounts, 6 to 8 inches, fell over the western and northern portions of the state from the Mountains east across the Foothills, Piedmont, northern Coastal Plain, northern Coastal Area, and the northern Outer Banks. The largest rainfall totals occurred at Oxford, located in the northern Piedmont (8.79 inches), Robbinsville, located in the southwest Mountains (8.72 inches); and Raleigh, in the northeast Piedmont (8.16 inches). Drier than normal conditions were limited to portions of southern and eastern North Carolina where rainfall totals of between 2.25 and 4 inches were recorded. These values were only half of normal. Tarboro, located in the Coastal Plain, was the driest spot, tallying only 2.35 inches. Mocksville, located in the western Piedmont, received only 2.86 inches. Temperatures during July 2004 averaged slightly above normal in the eastern sections, while the western part of the state averaged slightly below normal. The Outer Banks were an exception with monthly temperatures averaging around 1.5 above normal. There was only one prolonged period of hot weather during July. It occurred from the 4th through the 15th when daily highs frequently reached the 90s with little thunderstorm activity. The last two weeks of the month featured scattered to occasionally numerous thunderstorms that brought clouds, significant rains, and cooler daytime temperatures to North Carolina.
