SUMMARY OF CLIMATOLOGICAL DATA
... EXTREME, RECORD HEAT AND VERY DRY CONDITIONS FOR MOST STATIONS ...
... SEVERE TO EXTREME DROUGHT COVERED MUCH OF THE AREA ...
What a hot, and for most, a dry August 2007! Have been keeping weather records for 40+ years in Southeastern Virginia and since 1995 for monthly ACON VA/NC/SC summaries and simply don't recall temperatures with the maxes reported below. Several maximum temps from reports below are in excess of 105° ! Now that's just incredible! In fact, look at Charlotte's number of days reaching or exceeding 90° ... 31!! Yes, every day of the month reached 90° or higher. Roanoke and Danville in Virginia weren't too far behind in that category.Rainfall for most was below normal although some scattered, intense thunderstorms produced excessive totals for Chesterfield, Richmond, and Woodstock in Virginia. In South Carolina, North Myrtle Beach recorded rainfall well in excess of the normal while at unusally (usually!) dry Lumberton, North Carolina, rainfall measured 5.18"!

AKQ: SUMMER IN REVIEW: HOW HOT WAS IT? http://www.erh.noaa.gov/er/akq/climate/FACTS/summer_2007_review.pdf NWS Wakefield (AKQ) has a review at its website of the summer weather 2007 for its area of forecast responsibility.

WHY DO THE LEAVES CHANGE COLOR? Here are some interesting tidbits from the Colorado Climate Center (excerpted from the CoCoRahs website). The US Forest Service has put together a nice web site explaining just why leaves change color. Visit: http://www.na.fs.fed.us/spfo/pubs/misc/autumn/autumn_colors.htm And if you are just trying to find out where the leaves are turning during a certain week or in a certain place in the country, the Foliage Report Network: http://www.foliagenetwork.com/reports/ keeps track of leaf colors in the eastern half of the county and the US Forest Service keeps you advised on fall colors throughout the US at: http://www.fs.fed.us/news/fallcolors/. The study of periodic plant and animal life cycle events that are influenced by environmental changes, especially seasonal variations in temperature and precipitation driven by weather and climate visit the National Phenology Network Web site at: http://www.uwm.edu/Dept/Geography/npn/.
NWS CHANGES WEATHER ALERTS Found this article posted by the Associated Press . Check it here. Likely at NWS home pages too by now. As some news articles disappear online as quickly as they arrive, you can do a Google Search using "NWS Changes Severe Weather Alerts."
EXTREME WEATHER H. Michael "Mike" Mogil, Certified Consulting Meteorologist and national weather educator with "How the Weatherworks, LLC" will release his new book EXTREME WEATHER (and climate) in October 2007. Mike says it's a real weather book, not just weather records, and goes into everything from storms, media reporting, and local weather through climate change. Preliminary info can be found at http://www.weatherworks.com.
ROCK:CLIME From the Rocky Mountain Research Station - Moscow (Idaho) Forestry Sciences Laboratory comes this interesting site our friend Kevin Shaw of ACON - MD/DE/DC passes along. WYSIWYG and may be of keen interest to some of you. Visit: http://forest.moscowfsl.wsu.edu/cgi-bin/fswepp/rc/rockclim.pl.
ENTERING THE DEGREE SYMBOL ° People like to mention the temperature in their weather comments. You may not know that you can type a degree symbol ° instead of typing out the word or using a word processor inserted character. It doesn't require a special keyboard. Simply hold down the Alt key and type 0176 (or 167) on the number pad. Release the Alt key and the symbol appears. This doesn't work with the numbers above the letters, just the number pad! On a Mac, the degree symbol is shift-option-8. Word processors (WORD, Word Perfect, ...) allow you to insert the degree symbol but it's a character specific to that particular word processing program and does not translate to HTML when I copy and paste your comments. If you wish to insert a degree symbol we can use, simply follow the directions above with the Alt and Shift keys. (The process above also works in DOS based programs! Info above partially taken from the CoCoRahs website.)
MIGHTY LAKE SUPERIOR MYSTIFIES SCIENTISTS "Something seems amiss with mighty Superior, the deepest and coldest of the Great Lakes, which together hold nearly 20 percent of the world's fresh surface water." Read more: here.

Virginia:
Annandale - Lowell sends these additional notes: " August was hot but near average in precipitation. The average mean temperature was 78.1 degrees, a departure of +2.5° F. It was the sixth hottest August in the last 27 years and the warmest since 2005. On 14 days the temperature was equal to or above 90° F and 4 days equal to or above 95° F. Only four Augusts had more ninety-degree days in the last 27 years. (1980, 1983, 1988, 2002) Only 1983 and 1988 had a higher maximum temperature reading for August in the last 27 years than this month's 99° F recorded on the 8th. It was also the highest temperature record here since July 6, 1999 when it was 100°F and the highest in August since August 15, 1988 when it was also 100. Only five times in the past 27 years has the maximum temperature been higher than it was on the 8th. The daily mean temperature for the 8th was 88.5°F the warmest day ever recorded in August. This year has had 38 days with a maximum temperature of 90°F or more. The minimum temperature of 78°øF on the 8th also tied for the highest minimum temperature ever recorded in August in the past 27 years. It is also interesting that the lowest temperature during this August was 62°F and in every August in the past 27 years it has been lower except 2001 when it was also 62°F. The average is 56°F and the record minimum for August is 46°F. We had eleven days with measurable precipitation that was the most since 2004 but the total for August was still - 0.05 inches below average. The August rainfall was essentially average but 49 percent of the rain came on the 20th and 21st. Since Dec. 2006 only two of the last nine months have had above average rainfall. For the year we have a deficit of -8.26 inches in precipitation. A 27 mph wind gust from the west on the 16th at 924 hours was the highest wind recorded in August but less than the average of 30 mph. The wind run for August was 781.1 miles the most since wind run records were started in 2002. The lowest relative humidity for the month was 25 % on the 18th and was the least in August since 1998 and dew point temperature fell to 40°F on the 18th, which is a new record for August since dew point records were started in 2003. August DAILY Records Tied or Broken - (27-Years of records): HIGH maximum temperature: 7, 8, 25; HIGH minimum temperature: 7, 8; HIGH range temperature: 12; HIGH precipitation: 21. Summer Records - June, July, August: The average mean temperature was 76.9°F. It was the sixth hottest summer on record at this station in the last 27 years. Rainfall for the summer was 7.05 inches. The summer of 2007 came out as the 2nd driest in the last 27 years. The record is only 6.13 inches in 1985. " [ + - ]
Arlington - From NWS WBC comes these notes: " HIGH PRESSURE OVER THE WESTERN ATLANTIC DOMINATED THE WEATHER PATTERN FOR MOST OF THE MONTH BRINGING WARM CONDITIONS THANKS TO A SOUTHERLY FLOW. IN FACT...AUGUST OF 2007 ENDED UP BEING THE 14TH WARMEST AUGUST ON RECORD. AS FOR PRECIPITATION...3.47 INCHES OF RAIN FELL THIS MONTH THAT IS VERY CLOSE TO THE NORMAL PRECIPITATION OF 3.44 INCHES. DUE TO THE VERY DRY CONDITIONS BEFORE AUGUST...WE STILL REMAIN ABNORMALLY DRY FOR THIS YEAR DESPITE THE NEAR NORMAL RAINFALL THIS MONTH.
Bridgewater - " The temperature was 4.5 degrees above normal while the precipitation was about an inch above normal. The total precipitation for the year is about 2 inches below normal. There were 7 thunderstorms during August. Several severe thunderstorms occurred near Bridgewater with some damage. None hit our town. The first part of the month was very dry when only .70 inches of precipitation fell. In the last 16 days, 4.18 inches of rain occurred. One Sunday, 3 thunderstorms exploded nearby, but just missed us. The lawns and farmer's crops are in good shape in spite of the dry weather. We got just enough rain to keep the grass rather green. Some areas not far from Bridgewater were not as lucky. " - [ + + ] - notes from Clayton
Centreville - " High `n dry once again with no records set and only a moderate amount of memos noted in the complaint department. For a summer in the DC area, what more could a meteor monitor ask for. Ranking third in the year with the warmest average temperature and fifth of the past nine for the degree of lack of rain, August doesn't find a slot in the record books at all this year. The average monthly temperature came in at 78.2°, 4.9° above the published average. This was partially driven by a monthly high of 99° on August 8th and 14 days with highs of 90° or greater. Three mornings shared 62° for the lowest temperature for the month on August 19, 20, and 22. The average minimum of 68.9° for the period was 7.8° above the established value of 61.1° value. That was the second warmest average low running just behind January which was nearly 10° above the established average monthly low. The precipitation received in August was about enough to wet the rock and fill a couple of ice trays, but not much more than that. Only 2.31" accumulated in the bucket; an amount equal to 64% of the 3.61" that is claimed to be our expected average for the month. Our greatest daily amount of 0.83" fell on August 20th and represented 36% of the monthly total. For the year, we are standing ay 18.69" on the books which is 10.04" shy of where we should be at this time of the year with 28.73". This is 65% of our annual to date value. I'd have a word with the brave souls down at the tribe to get on down and start dancin', but I'm afraid of what might come. I think we'll pass on anything that extreme for right now. " - [ + - ] - report from Paul
Chantilly - Russ Topping sends these notes: " August precipitation also below normal. We are now running 8.9" below statistical average, for the year. On the bright side, our 90 day departure from normal was running -6.1" until August reduced this to -3.98". For the month, precipitation was 1.49" below normal, despite the week of August 20th, during which a front stalled over us and we saw a week of clouds and occasional rainfall. August temperatures were 2.0° above normal, with record highs recorded at nearby WBCIAD Dulles Int'l Airport on the 6th (96°), 7th (97°), 8th (101°) and 25th (97°). We heard the rumble of thunder on the 9th and 25th. A passing thunderstorm provided 0.45" of rain on the 20th.. *Please note, anemometer is currently partially obstructed " - [ + - ]
Falls Church - Windie reports: " August 2007 was a very warm, humid month for the most part. August was roughly 3 degrees warmer than July, normally my hottest month. Rainfall was slightly above average for the month, which was very welcome considering what a dry summer it has been. On the 8th my high of 102 degrees broke a record high for this date. " - [ + + ]
Hampton - Dave sends these additional notes: " Severe drought condition persist over Hampton into early Fall. Yearly Rainfall is 15 inches below normal. A all time station record high occurred on August 8 of 104 with the previous high of 103 in August of 1980. " - [ + - ]
Herndon - Randy sends these notes: " AUGUST WAS ANOTHER WARMER AND DRYER THAN AVERAGE MONTH CONTINUING THE TREND FOR THE YEAR. THE TEMPERATURES REMAINED IN THE UPPER 80S AND 90S FOR MOST OF THE MONTH, EXCEPT FOR A SHORT STRETCH FROM 18TH THROUGH 23RD WHEN WE HAD A COOL, WET FEW DAYS. THE TEMPERATURES PEAKED ON THE 8TH WHEN WE HIT 100 DEGREES FOR THE FIRST TIME IN SINCE AUGUST 1997. OVERALL, WE ENDED THE MONTH 1.5 DEGREES ABOVE NORMAL WITH TEMPS EXCEEDING 90 DEGREES 15 TIMES. THE PRECIPITATION OCCURRED SPORADICALLY THROUGH THE MONTH. THERE WERE TWO DISTINCT PERIODS OF THUNDERSTORM ACTIVITY: THE FIRST FROM THE 3RD THROUGH THE 9TH OF THE MONTH AND THE SECOND FROM THE 16TH THROUGH THE 26TH. THE SECOND PERIOD BROUGHT THE HEAVIEST RAINFALL AMOUNTS WITH THE MOST OCCURRING ON THE 20TH AND 21ST WHEN I RECORDED 1.36 INCHES OF RAIN. THE MONTH ENDED UP AT ONLY 2.69 INCHES OF RAIN WHICH WAS ABOUT 1.5 INCHES BELOW NORMAL. THE TOTAL PRECIPITATION FOR 2007 IS NOW ONLY 19.98 INCHES; OVER 10 INCHES BELOW. UNLESS WE GET INTO A MUCH WETTER PATTERN, THIS WILL EASILY BE THE DRIEST YEAR I HAVE EVER SEEN SINCE I BEGAN MY WEATHER SITE 15 YEARS AGO. NET RESULT: MY YARD AND GARDEN WATERING HAS TO CONTINUE FOR A LITTLE WHILE LONGER. " - [ + - ]
Ladysmith - Danny sends these additional notes: " August got off to a very hot start but ended very nicely with a stretch of below average temperatures. Despite that stretch, temperatures finished well above normal for the month. Precipitation was still below normal as it seemed like all the "good" storms that popped up nearly every day during the mid to late part of the month would either hit north or south of Ladysmith. Year-to-date rainfall is now over 8" below normal. " - [ + - ]
Portsmouth - " The average temp was 1.3° above the norm while rainfall was 94% of the normal or -0.35". A lot of new station records were noted this month and posted here: 5TH WIND GUST 38 mph [prev 28 1989]; 8TH TEMP MAX 97° [prev 96°] MAX MIN 80° [prev 78° 1999]; 9TH TEMP MAX 98° [prev 96° 1977]; 10TH WIND GUST 30 mph [prev 27 1998]; 20TH TEMP MAX MIN TIED 75° [prev 2002]; 21ST RAIN 1.75" [prev 0.85" 1979]; 21ST WIND GUST 38 mph [prev30 1989]; 25TH TEMP MAX MIN 75° [prev 74° 1979]; 26TH RAIN 1.21" [prev 0.22" 1996]; 21ST - WIND GUST - 38 mph [prev 30 1989]; 25TH - TEMP - MIN 75° [prev 74 1979]; 26th - RAIN - 1.21" [prev 0.22" 1996].

Raleigh - Bob adds: " Hot and dry!! At least twenty-eight days the daily maximum exceeded 90 degrees including five days of 100 degrees or greater. The average daily temperature was 4.7 degrees above normal. The hot temperatures usually means little cloud cover and that was the case during August. Rainfall for August totaled only 1.62" which is 2.16" below normal. Precipitation for the year is 5.35" below normal. Still have some instrument problems thus incomplete data for win speed.
