SUMMARY OF CLIMATOLOGICAL DATA 


JULY 2007


... FOR MOST STATIONS, BELOW NORMAL TEMPS & RAINFALL ...

Summer was well entrenched with temps rising often into the 90s. Still, there were no heat waves in June or July which sent temps to or above 100 an interesting statistic for the region. Most all areas were cooler and drier than normal but a few stations were the recipients of thunderstorm activity that pushed total amounts above normal. Of note, thunderstorm activity was more scattered in nature with no large outbreaks.

  • DROUGHT MONITOR    http://www.drought.unl.edu/dm/monitor.html    More information on drought can be found at NOAA's Drought Information Center http://www.drought.noaa.gov/


  • ANOTHER HURRICANE SITE    Our friend Larry Atkinson, Professor of Oceanography at Old Dominion University, sends along this URL for your consideration: http://rammb.cira.colostate.edu/products/tc_realtime/storm.asp?storm_identifier=AL042007.


  • 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: http://news.aol.com:80/story/_a/mighty-lake-superior-mystifies/20070729134609990001.

    Virginia:

    Annandale - Lowell sends these additional notes: " July was the driest July in my records with only 1.69 inches precipitation and a -2.63 inch departure and a little below average in warmth. The previous driest July was in 1985 when 1.77 inches was recorded. The maximum one-day rain was only 0.46 inches which was the least for any of the past 27 Julys. It was the first July without at least one rain of an inch or more since 1999. July's mean average temperature (77.7F) was only a - 0.1F departure from average but was coolest since 2004. It was also the fourteenth coolest on record in the last 27 years. July's lowest maximum temperature was 80F which is the second highest for any July since 1995 when the record of 82F was set. July's average temperature range was 21.0F the most since 1988 and only four years have been greater in the last 27 years. The 28F daily temperature range on the 8th and 9th was the most for July since 2002. The lowest dew point for July was 43F on the first at 1357, which is the lowest for July since dew point records were started in 2004. The maximum dew point for the month was also the lowest since 2004. The monthly average relative humidity was 65% and the lowest since 1993 when 64% was the average. The maximum gust of 27 mph from the west on the 15th at 2011 was the least for the maximum monthly wind gust recorded for July since 2004. But the total wind run for the month was 722.4 miles the second highest since wind run records were started in 2002. There were only 2 daily records set this month the least for any month since July 2004! July DAILY Records Tied or Broken- (27-Years of records): LOW maximum temperature: July 5 and LOW range temperature: July 5. " [ - - ] 

    Bridgewater - " The temperature was 1 degree below normal while the rainfall was 1.7 inches below normal. There were 3 thunderstorms during the month. The precipitation for the year is 18.65 inches which is 2.82 inches below normal. Bridgewater wasn't as dry as some other places. We got just enough rain to get by without too much damage to gardens and farm crops. However, we could use more. " - [ - - ] - notes from Clayton

    Centreville - " Don't know how many different ways there are to write about nothing, but I'm willing to give it a try yet again. At the top of the list for excitement was our gust of wind on July 4th. A blast of 28 miles per hour from the NNW at 17:44 was just in time to clear the remnants of a lame excuse of a rain shower in time for the holiday festivities that followed. After that however, all the celebrations were downhill for the rest of the month. A maximum temperature of 97on July 9th was one of the nine days of ninety degrees or greater, but was a far cry from the 103 record set in 1998. The average monthly high was just 0.1 above the 86.9 published average monthly high temperature while the monthly average low came in at a mild 3.4 over the 63.2 we should expect. Five days this month logged average lows of 67 with July 6th managing to be a fairly `normal' day when the average high, the average low, as well as (within a 0.01") the monthly average barometric pressure all happened within shouting distance of one another on that date. Except for May, July recorded the second lowest monthly rainfall amount with 1.85", or 52% of the monthly average of 3.57" being accumulated. July logged 42% of its total precipitation on the 27th and 28th with the final tip yielding 0.77". Setting aside all these shattered precipitation records of July, there were a total of eight days with rainfall of 0.01" or more, but the yearly lack of rain caused water deficits to continue t o increase. This year to date, 16.38" has fallen placing us 8.74" below, or 65% of our 25.12" average for this time of the year. " - [ + - ] - report from Paul

    Chantilly - Russ Topping sends these notes: " Another dryer than average month brings us deeper into drought conditions. Precipitation was 0.7" below normal, mainly due to a slow moving afternoon thunderstorm that wandered close enough to us on the 29th. The rain relief has been very scattered, provided only by thunderstorms. Temperatures averaged 0.9 degrees below normal, at my recording station. *Please note, anemometer is currently partially obstructed " - [ - - ]

    Falls Church - Windie reports: " A dry month with average temperatures. Worst drought in quite a few years... my lawn as well as many in my neighborhood is starting to brown. " - [ M - ]

    Hampton - Dave reports these additional notes: " July continued the very dry tend this summer. I have noticed an unusual number of cool, sunny, windy days so far this summer, although in recent weeks, that has not been the case. July would have been the driest month ever at Langley AFB and at my Hampton station if it not been for a thunderstorm on July 29 that produced 0.82 inches of rain. Even with this, it is still one of the 5 driest July's at both locations. Records for July: Record Low of 58 on 7/03 " - [ -/+ - ]

    Herndon - Randy adds: " JULY WAS ABOUT AVERAGE TEMPERATURE WISE, BUT ANOTHER DRY MONTH. THE TEMPERATURES WERE A LITTLE MORE STEADY WITH PERIODS OF SERVERAL DAYS OF HIGHS OVER 90 FOLLOWED BY SLIGHT COOLING TO THE LOW TO MID 80S. OVERALL WE ENDED THE MONTH 0.5 DEGREES BELOW NORMAL WITH TEMPS EXCEEDING 90 DEGREES TWELVE TIMES. LIKE THE TEMPERATURES, THE PRECIPITATION OCCURRED SPORADICALLY THROUGH THE MONTH. ALTHOUGH THERE WERE MANY DAYS WITH THUNDERSTORMS IN THE AREA; MOST OF THEM AGAIN WENT AROUND MY SITE. I DID RECORD MANY DAYS WITH THUNDERSTORM ACTIVITY, BUT ONLY ONE, ON THE 4TH , PRODUCED ANY SIGNIFICANT RAIN (1.2 INCHES). AT THE END OF THE MONTH WE HAD SEVERAL DAYS WITH AFTERNOON AND EVENING THUNDERSTORMS IN THE AREA, BUT THEY ONLY PRODUCED A TOTAL OF ABOUT INCH THROUGH THE PERIOD. THE MONTH ENDED UP AT ONLY 1.88 INCHES OF RAIN WHICH WAS ABOUT 1.8 INCHES BELOW NORMAL MAKING IT THE THIRD DRIEST JULY IN THE PAST 14 YEARS OF MEASUREMENT AT THIS SITE. THE TOTAL PRECIPITATION FOR 2007 IS NOW ONLY 17.29 INCHES; OVER 8.7 INCHES BELOW. THIS MONTH I HAVE ADDED A DAVIS VANTAGE PRO WEATHER SYSTEM TO MY WEATHER SUITE. SO I AM NOW SUBMITTING NEW DATA ON WINDS, HUMIDITY, AND BAROMETRIC PRESSURE. " - [ - - ]

    Ladysmith - Danny sends these additional notes: " JULY BROUGHT SEVERAL STRETCHES OF WELL BELOW NORMAL TEMPERATURES AND VERY LITTLE PRECIPITATION. YEAR-TO-DATE RAINFALL IS NOW NEARLY 7" BELOW NORMAL. " - [ - - ]

    Portsmouth - " The warm, drier than normal conditions of May and June reversed this month. A cooler than normal July here, partly due to increased NE flow as high pressure settled south along the Mid-Atlantic from New England and partly due to the above normal rainfall. The average temp was 1.6 below the norm while rainfall was 116% of the normal or +0.85". Frontal passages occurred at 4 times: on the 1st, the 6th, 12th, and on the 20th. Station records included: 22nd - TEMPERATURE - Minimum 63 [previous 65 1982] 30th - RAINFALL - 1.47" [previous 1.17" 1991] 30th - WIND GUST - 30 MPH [previous 23 MPH 1987]. At July's end, yearly rainfall was only 75% of the norm or -6.89" and steadily increasing despite July's excess. Quite a bit of haze was noted during the month; but after all, it is summer. The warm, drier than normal conditions of May and June reversed this month. " [ - + ]
