SUMMARY OF CLIMATOLOGICAL DATA
JULY 2000


...Cooler, Wetter Midsummer Month For Most
as Mid-Atlantic Trough Develops...

Most every station reported a cooler than normal July, thanks to the unusual southern movement of high pressure centers repeatedly carving out weak Mid-Atlantic troughs.  While the cooler weather affected everyone - even keeping 90 degree readings at bay in Northern Virginia (a rather extreme July rarity) - rainfall did not affect us all with such uniformity.

Most all stations in Virginia saw above normal rainfall, as did the Raleigh area northeast and east to the coast then south along the North and South Carolina coasts.  But other areas of North and South Carolina saw below normal rainfall.  Days with thunderstorms and numbers of storms on those days were above normal.  While the drought (highlighted in last month's report) was lessened in areas along the North and South Carolina border, it persisted in many areas of South Carolina.

CAE ONLINE Have not seen CAE's web page online before but came across it during data search.  Additional data presented included those for Orangeburg and Augusta!  Visit the home page at:  http://www.nws.noaa.gov/er/cae

A BORROWED IDEA!  Decided I liked the manner in which  extremes reported by group members of the ACON MD/DE/DC is presented by Gary Gallaher (Dover) in their monthly summaries.  So, I've added it here and plan on continuing it.  While our geography covers much more territory than theirs (thus greater variance), the data listed will still provide a snapshot of the previous month's extremes.

ONE LAST TIME!!!  DON'T FORGET TO SEND YOUR MONTHLY NOTES VIA EMAIL IF YOU CAN

If you have email, then it would really help me if you could send your monthly notes section via the Internet.  Many of you already do this and I can easily copy and paste.  Some of you still send in your handwritten forms but you also have email. Please continue sending in those forms but just drop me an email at the first of the month with your notes if you can work this in to your schedule.  Such e-notes would save me typing time!

NOTES FROM "AROUND THE LEAGUE"

Virginia:

Annandale -  Lowell sends these notes: "July was the coolest on record here and the second wettest July with 6.73 inches departure was +2.62 inches. The wettest July here was in 1992 with 6.97 inches. The average maximum  temperature was  83.1° with a departure of  -4.4°.  The average minimum temperature  was 65.6° with a departure of -2.9°. The average mean temperature  was 74.4° with a departure of -3.7°.  The mean temp. for June was +0.4° higher than July's.  We had only 4 days with temperatures of equal to or greater than 90° which set a new record. The previous record was 5 set in 1984.  Highest maximum temperature for July  was 91° on the 3rd  and 18th which was the lowest July maximum temperature on record.  The old record  was 93° (records since 1980).   This July was the cloudiest since 1994 which had 17 days with rain. We had 12 days with rain this July the most since 1996.  The 2.10 inches of rain on the 28th was the most rain  in a calendar day for July since 1981 when a record of 3.25 inches fell.  The 1.74 inches recorded on the 28th was a new one hour rainfall  intensity record for any month  (records since 1990).  The average daily temperature range was 17.6° the least since 1996 and  the maximum range for any day was 25° on the 2nd the least range in a July month since 1987.  The max. wind for the month was 30 mph at 1740  from the WNW on the 10th  in a thunderstorm.  July 2, 2000 - Thundershower with heavy rain at 2030 with a maximum intensity of 0.21 inches in five minutes.  Total rain for the day was 0.83 inches in two periods-- 2015-2100 ,  2145-2250.
July14, 2000 - Slow moving thunderstorm between 1700 and 1810 gave 0.51 inches with a maximum  intensity of 0.21 inches in 15 minutes.  The second slow moving thunderstorm between 2220 and 0135 of the 15th  gave much lightning and 1.54 inches rainfall with the maximum rainfall intensity of 0.82 inches in 15 minutes and 0.30 inches in 5 minutes around 2300.   Total rain recorded for the 14th was 1.95 inches and 0.10 inches on the 15th.   July 28, 2000 - Total rainfall in this storm was 2.10 inches. The most rain in one day since April 17, 2000.   Maximum one hour intensity 1.74 inches set a  new one hour rainfall  intensity record for any month  (records since 1990).  Maximum five minute intensity was 0.32 inches.  Maximum one minute intensity 0.08 inches between  1945 and 1946."

Arlington - NWS WBC notes DCA's mean temp was a whopping 5.4o below normal while the rainfall departure was +1.71".  Year-to-date precip was 6.07" above normal.    NO RECORDS WERE SET AT NATIONAL AIRPORT DURING JULY.   JULY WAS ANOTHER WET MONTH FOR THE WASHINGTON AREA. ALSO IT WAS DECIDEDLY COOL FOR WHAT IS TYPICALLY OUR HOTTEST MONTH OF THE YEAR.   JULY WAS ACTUALLY COOLER THAN JUNE THIS YEAR...A FEAT THAT HAS ONLY BEEN MATCHED THREE OTHER TIMES IN THE 20TH CENTURY /1925/1943/1984/.  JULY 2000 WAS OUR COOLEST JULY SINCE 1918 AND OUR THIRD COOLEST OF THE TWENTIETH CENTURY. THAT WAS WELL AIDED BY THE FACT THAT WE HAD ONLY ONE NINETY DEGREE DAY...WHEN WE REACHED 91 ON THE 10TH.  THE AVERAGE IS
FOURTEEN...WHILE JUST LAST JULY WE HAD 22 DAYS OVER NINETY DEGREES. THE MONTH ENDED UP NEARLY FIVE AND A HALF DEGREES BELOW NORMAL...AN EXTRAORDINARILY LARGE DEPARTURE FOR A SUMMER MONTH.  NEARLY ALL THE NIGHTS THIS JULY HAD LOW TEMPERATURES IN THE 60S WHILE MOST DAYS HAD HIGHS IN THE 80S. MOST DAYS WERE TROPICAL WITH PARTLY SUNNY SKIES...SCATTERED SHOWERS AND THUNDERSTORMS...AND HUMID AIR.  THE RAIN WAS SPREAD OUT OVER NEARLY HALF THE DAYS OF JULY. AT OVER FIVE AND A HALF INCHES OF RAIN...IT LOGGED AS OUR SECOND WETTEST JULY OF THE DECADE. COMBINED WITH JUNE/S HEFTY TOTAL OF NEARLY FIVE INCHES...THIS MONTH IS CONTINUING TO PRODUCE OUR WETTEST SUMMER SINCE 1989.  THIS ALL PRODUCES QUITE A CONTRAST FROM LAST YEAR/S DROUGHT.  Our Erica Page of Falls Church also keeps records of DCA's stats and this july ranked as the 9th coldest ever in Washington and the coldest since records began there in June 1949.

Blacksburg/Roanoke/Lynchburg Area - IN BLACKSBURG...RAIN SEEMED MORE THE RULE THAN THE EXCEPTION DURING THE MONTH.   IT RAINED ON 18 OF THE 31 DAYS. HEAVIEST RAINFALL WAS .92 " ON THE 4TH. HEAVY RAIN OF OVER 1/2 INCH FELL ON THE 4TH...THE 12TH...THE 19TH...THE 23RD...AND THE 31ST.

In Blacksburg, the monthly mean temp was 2.0o below normal while precip was 1.16" above normal.

Bridgewater - Clayton reports:  " With all the rain during the latter part of the month, it is difficult to believe that the month was .82 inches below normal. However, very little rain fell during the first 18 days of July. Only .54 inches fell during this period, while 2.76 inches fell during the last 13 days.    Places just a few miles from Bridgewater had much more rain. Huge downpours occurred due to storms that formed and then stalled.  Flash flooding  was reported in a number of areas.   Bridgewater was on the light side rain-wise, but we got enough. At the time of this writing, my garden is muddy. My watermelons and cantaloupes won't take much more rain.    If my thinking is correct, the last 9 days of the month had forecasts of a chance of showers and thunderstorms. The same forecasts exist for the
first 4 days of August. I have never known this many consecutive days with this kind of forecasts.   The last part of the month was rather exciting with showers and thunderstorms popping up almost every day.  The temperature for the month was about three degrees above normal.  Most of the months this year have been above normal. Also, the precipitation was about three inches above normal.  With the heavy precipitation in June, this year's precipitation is very close to normal.    A spectacular lightning display occurred on the night of the 21st. It was the most exciting lightning show that I had seen for some time.     With the abundance of moisture, the lawns are green, and gardens are growing. The farmers corn fields look great.  What a contrast to last year!"

Centreville - Paul reports, "Wow, what a July!!!  I can't remember any as great as this for a   l o n g   time.  The average daily temperature was 2.5o  below the 77.7o normal, and the average highs were almost 5o below normal.  The nightly lows were also below the norm, but by only .02o .  Am I missing some mercury or what?  July 24th had neither heating or cooling degree days with the high for the day at 66 ,  the lowest high for the month.  Precipitation did a good job on the flowers at .02" above the average, with nearly 2/3d's of the 3.77" total falling during the last half of the month. "

Dulles - The monthly mean temp, according to NWS WBC, was 5.3o below normal while precip for the month was 0.79" above.
Rainfall for the year at month's end was 0.22" below the norm.

Falls Church - Erica reports: "July was a cool, wet month.  There were no 90o days here which is quite unusual.  Had 8 days with thunderstorms, some severe.  Nice break from the heat and humidity 'though!"

Fredericksburg - No day hit 90o and precipitation fell on 14 days, saith Ken, with rainfall again much above average .

Hampton - Dave sends these notes:  "A very wet and humid month especially from mid month onward.  Monthly temps were cooler than normal due to the rain and clouds near the end of the month. An incredible rainfall occurred on the morning of the 24th as 6 to 7 inches of rain fell in about 4 hours across Hampton. many areas experienced the worst flooding citywide since 1972 . Streets were covered in
as much as 3 to 4 feet of eater during the event.  Station Records:  tied record low 62 on 7/8; daily rainfall record 6.50 on 7/24."

Herndon - "Most notable for July 2000 were the much cooler than normal temperatures. July temperatures averaged 4 degrees below normal in Northern Virginia. We also welcomed the abundant rainfall which was 0.70" above normal at my station. A line of severe storms rolled through on the 28th and knocked out our phone lines for the weekend."  - Russ' notes

Louisa - A severe thunderstorm was noted on the night of the 14th with rain of 2.6" but with no damage. - notes from John

Lynchburg - From NWS BCB:  IN LYNCHBURG...RAIN FELL ON 22 DAYS OF THE MONTH. HEAVIEST RAINFALL OCCURRED ON THE 28TH WHEN 2.1" FELL. SECOND HEAVIEST RAINFALL WAS ON THE 19TH WHEN 1.59 INCHES FELL. THIRD HEAVIEST WAS ON THE 11TH WITH 1.02".
The monthly mean temp was 4o below  normal.  Rainfall was 2.73" above the norm.

New Market - Joyce writes:  "The month has been cooler and much wetter.  Have had 4 storms the past week.  Can not get into the fields for second cutting of hay."

Newport News -  A VERY COOL AND WET MONTH THAT TIED OR BROKE RECORD LOWS ON 8 DAYS.   FLOODING RAINS  ON THE 24TH THAT WAS REMINISCENT OF LAST SEPTEMBER'S HURRICANE FLOYD. - Report from Gary

The monthly mean temp was 3o below normal while precip was 3.25" above the norm.

Vienna - Robert notes that "July was the coolest in my records, since 1986.  Also, noted the fewest 90o days in any July month since 1986."

Woodstock -  Lauck reports "the coolest July in 15 years of record keeping.   Precip was the 4th highest.  Another wet month, with the corn as high as an elephant's eye...but the hydrologists are saying that it's just good surface moisture with little recharge of the aquifers.   Modest but very regular rain has kept crops in fine condition, but done little to recharge the aquifers."

Wilmington -  From NWS ILM:  THE AVERAGE TEMPERATURE FOR THE MONTH OF JULY IN WILMINGTON WAS 2.1 DEGREES BELOW NORMAL.   NO TEMPERATURE RECORDS WERE BROKEN OR TIED IN JULY.  THE TOTAL RAINFALL WAS  0.30 INCH BELOW
NORMAL.   67 % OF POSSIBLE SUNSHINE WAS RECEIVED IN JULY (NORMAL IS 64 %).   THE AVERAGE WIND SPEED FOR THE MONTH WAS 6.1 MPH. THE 10TH WAS THE BREEZIEST DAY WITH A DAY-LONG AVERAGE OF 11.9 MPH. BUT THE 22ND SAW BOTH THE HIGHEST 2-MINUTE WIND (25 MPH FROM THE WEST) AND THE PEAK GUST (31 MPH FROM THE WEST) AS A THUNDERSTORM PASSED.

South Carolina:

Columbia - NWS CAE reports the monthly mean temp was 0.7o in excess of the norm.  Rainfall was 2.55" below the norm and the year-to-date rainfall was 8.64" below the normal.  A 100oday was noted on the 11th.

Charleston - "The month of the waterspouts...that's what July 2000 can be called on the South Carolina coast.   Three waterspouts formed along the shore in late July, with two coming ashore.  On July 23rd, two formed.  In Georgetown county, near Litchfield Beach, a large waterspout was spotted by the public and SKYWARN weather spotters.  The NWS in Wilmington issued a tornado warning at 824
PM.  Video seen later indicated that this was a tornadic type waterspout in a strong thunderstorm.  Later that evening, a waterspout came ashore in the Isle of Palms (Charleston county) near the Wild Dunes residential district.  Minor damage was reported on oceanfront property, with one house evacuated.  NWS Charleston (i.e. yours truly) issued a tornado warning at 922 PM.  A week later, on July 30th, another waterspout was sighted about 5 miles south of Kiawah Island.  A tornado warning was issued for south central Charleston county by NWS Charleston at 738 PM, followed by a special marine warning at 744 PM.  The Charleston county waterspouts were not detected by radar, but these storms do not have to be very strong to produce waterspouts.  The ingredients needed for waterspout development is very warm ocean waters (water temperatures were in the mid 80s) and some instability (a weak front was nearly stationary across the area on both occasions).   Waterspouts more commonly occur off the Florida coasts, but are not unusual off Georgia and South Carolina.

July 2000 was the first month to record a surplus of rainfall as compared to normal in quite a few months. The 10.81" recorded was nearly 4 inches above the normal.  The rainfall helped to cut into the yearly deficit of rain, but some areas south and west of Charleston continue with serious drought conditions.  Several weather fronts tried to work south into the region during July, along with sea breeze front action, which caused rounds of thunderstorms with heavy rainfall in some locations.  Across northern Berkeley county, east and north of Lake Moultrie, radar estimated over 12" of rain in about 4 days during late July.  On a couple of occasions, showers and
thunderstorms developed near the lake and "trained" across this area, dumping copious amounts of much needed rainfall.  However, many other areas did not share in the rainfall, especially near the Savannah River.

Records for July:  Downtown Charleston : July 6th  record high 98  tied   previously set in 1977 and  record high minimum  81  tied  previously set in 1990; July 16th  record high  98  previous record 97 set in 1970 and record high minimum 81 tied  previously set in 1986; July 20th  record high 100  previous record 98 set in 1986 and record high minimum  83  previous record 82 set in 1986.

Beaufort: July 11th  record high  99 tied  previously set in 1942; July 17th  record high minimum  80  previous record 77 set in 1948;
July 18th  record high minimum  81  previous record 79 set in 1986 : July 20th  record high minimum  81  previous record 79 set in 1986

Monthly precipitation was 3.97" above normal and the mean temp was normal.  Yearly precip to date was 3.82" below normal at month's end. --Eleanor
