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!

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.

"
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 (77.6°F) was
only - 0.1°F 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 90°F days.
July had only 9 days with 90øF 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 90°F days. This
year had 16 days of equal to or greater than 90°F 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 92°F; that occurred in 2000 when 91°F was the
maximum for the month. The maximum temperature for
2004 is still 92°F and is the first time in the last
24 years we have gone this long in the summer without a 93°F
or hotter day. The previous latest date was July 9, 1992.
July's average temperature range was only 17.4°F 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 4°F that occurred
on the 25th; the 24 year-record is 3°F 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

"
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.

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!

- 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.

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

- 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.
