Well, perhaps the biggest news for the month was the F0 tornado that
touched down in my development on the 9th. (I was at work missing the whole
thing). An F1 touched down west of the station near Purcellville and
Leesburg, but in both cases damage was mostly limited to trees and
tree limbs down. One home in Ashburn Farm was damaged from a portion of a
tree that fell against the house. Unfortunately - as luck would have it -
my weather station was experiencing a complete loss of signal condition on
its wireless link for most of that day. While no tornado winds were
experienced at the station, an aluminum flagpole mounted about one meter
from the mast holding the weather station was sheared off at its base.
No other damage was noted during the thunderstorm winds on that day
apart from shuffled lawn furniture and the like.
Continuing with my obsession about noting rainfall on the first day of the
month, July was the seventh month in a row with measurable precip (0.05")
of rain on the first. Looking at other Northern Virginia weather
stations, I noted quite a bit of spatial variance in rainfall amounts.
3.93" was recorded at my station, 0.42" above normal for July.
Temperatures for the month were quite seasonable overall, with the month
finishing at 0.9° above average. Wind was quite notably below average,
with a daily average wind speed of only 0.7 mph, well under the station
average for July (though the high wind speed for the month of 22 mph was -
just barely - a new station record for July). Average humidity for
the month was 76% and the average dew point was 67°. "

July was very wet and cooler and cloudier than average. July's mean average
temperature (76.8°) was the seventh coolest on record in the last 23-years
with a -1.0° departure. The 6.75" of rain made it the second wettest July
in the last 23-years with a +2.62" departure. It was the wettest July
since 1992 which holds the record with 6.97 inches. July had 14 days with
measurable rain that was the most since 1996 and was only three days
short of tying the record for the month. The 0.36" of rain that occurred
in five minutes on the 9th was the most intense since September of 2000
when 0.47" occurred in five minutes. This is also the eighth most intense
five-minute rainfall since these records were started in 1990. July was
also cloudier than average and the second cloudiest in 22 years of records
(no sky record for 1986). July's average sky cover makes it normally the
clearest month of the year.
July had only 8 days with 90° or above temperatures and last year we had
20 days. The total of equal to or greater than 90° is only a total of
12 days for 2003 the least since 1992 when 11 days occurred. The least is
8 days in 1982. In only five Julys in the last 23-years has the maximum
temperature for the month been less than 95°. The maximum for 2003 is
still 94° and is the first time since 1989 we have gone this long without a
July's average temperature range was only 17.3° the least since 1996 and
only three years have been lower in the last 23-years.
The maximum gust of 36 mph from the NNW on the 9th at 1700 was the strongest
wind gust recorded for July since 1998. The wind caused minor damage to
trees. The top was broken out of neighbor's Bartlett pear tree and one
other tree near Lake Barcroft was uprooted.
There were only 6 daily records set!
July DAILY Records Tied or Broken- (23-Years of records):
1 daily LOW maximum 23-year temperature record for the date: 2;
1 daily LOW range 23-year temperature record for the date: 2;

" - report from Clayton [ M + ]
July is theoretically the hottest month of the year for us, so it
is comforting to report a monthly average of 77° being only 1.9° above the
75.1° average. Speaking of averages, right about mid-month, July 17th
registered a high of 86°, a low of 68°, both of which happen to be the
high and low average temperatures for the month. For highs, we peaked at 94°
on three days in early July while a quarter of the days this month
registered 90° or better. All of these excesses though had just a marginal
affect at the high end, but they did help to produce an average high of 86.1°
or, 0.8° below the 86.9° normal. So far all this sounds like a fairly
typical July, and after the nightly lows enter the equation, I'm sure
you'll see that we did really well in that department too. With 67.9°
logged as our average nighttime temperature, we find that it was just 4.7°
warmer than the 63.2° that the record books suggest. A large number,
ten nights, logged overall lows at the monthly low average 68°. Except for
January '03, the nearly 5° difference between my recorded entries and
the record book was the closest any month has been to being average
for the whole year. Quite a significant accomplishment since no snow was
observed during the entire month. Precipitation for July was again
above the average, but this time only by an average amount. With 3.53"
considered normal rainfall for July, we exceeded that by 156% or 2.37"
for a grand monthly total of 5.80". Our average of average monthly
precipitation excesses this year is 160%, so we came in just four
tips of the bucket short of that. The greatest contribution to the
watering can happened on the 22nd when 1.92" fell in about an hour and
a quarter. The nearly two inches amounted to roughly a third of our
monthly total, and ended an eleven day mid-month dry spell.
This July doesn't stand out for reports of tornadoes, drought conditions,
record heat, or widespread flooding. Snowfall was even within limits.
This July was just sorta' unusually average."

July 2003 was cooler and wetter than average. We only had 10 days of 90° or
higher. The remnants of Tropical Storm Bill brought heavy rains on the
2nd and 3rd of this month and the night of the 10th into the wee hours of
the 11th brought a line of heavy thunderstorms through. Some of these storms
brought small hail. A windy day on the 21st produced a peak gust of 27 mph."
