SUMMARY OF CLIMATOLOGICAL DATA 



JUNE 2013

...TROPICAL STORM ANDREA BRINGS BENEFICIAL RAINS...

...TEMPERATURES AVERAGE SLIGHTLY ABOVE NORMAL...

...RAINFALL TOTALS WELL-ABOVE NORMAL...
  • TROPICAL STORM ANDREA - JUNE 2013     During the period June 5th through 7th, the first tropical storm of the season came out of the Gulf of Mexico and traversed northeast along the Southeastern Coastal Plain states. The storm became post-tropical on the 8th as it moved parallel to the Middle Atlantic and New England coasts. Here's the Tropical Storm Andrea Summary report for Southeastern Virginia prepared by NWS Wakefield (KAKQ)  http://www.weather.gov/akq/TS_Andrea_Overview


  • NWS AKQ MONTHLY RAINFALL ANALYSIS (Virginia)      Don't forget these new products for Virginia from NWS Wakefield compiled from ASOS...COOP...RAWS REPORTS | Monthly Rainfall Analysis - http://www.weather.gov/akq/MONTHLY_RAINFALL_ANALYSIS -


  • A GUIDE TO PERSONAL WEATHER STATIONS    Kevin Shaw (Member ACON MD/DE/DC) sends this link to an article about cooperative observers and personal weather stations that you all should find very interesting. Lots of links, interesting explanations, and a lot of rooftop station exposures that gets the best wind data exposure at the expense of poor temperature data exposure. Be sure to check out this one out! http://www.nytimes.com/2013/07/11/technology/personaltech/a-guide-to-personal-weather-stations.html?pagewanted=all&_r=1&


  • SCIENTISTS AND CLOUD RESEARCH    ACON MD/DE/DC Member Kevin Shaw sends another resource from NOVA LABS. Very interesting link to click on, showing scientists involved with all types of cloud research. Don't forget to click on the "MORE" link under each scientist to really find out more about them and their specific research. http://www.pbs.org/wgbh/nova/labs/meet-scientists/#cloud-lab


  • DULLES (KIAD) DETAILED ASOS DATA    ACON MD/DE/DC Member Kevin Shaw sends yet another resource! He notes: "Pretty cool website that our friend Alexander M sent me earlier today- it gives detailed obs data for the ASOS out at Dulles Airport near Sterling VA, for every minute from the present time going back 2 hours.. Changes every minute, giving you a 2 hour running data set of ASOS observational data. Enjoy! http://iadasos.org/1MinuteReport.php


  • THE HEAT INDEX: WHAT'S THAT? (from CoCoRaHS)   The Heat index (HI) is sometimes referred to as the "apparent temperature". The HI, given in degrees F, is a measure of how hot it feels when relative humidity (RH) is added to the actual air temperature. So if the temperature was 85F and the Relative Humidity was 85% the Heat Index value would be 99F. Believe me, that's an uncomfortable value. Many parts of the country have had heat index values over 100F the past couple of weeks. Thanks to the invention of air conditioning many are fortunate to find relief from the heat during these hot summer days. For those who do not have air conditioning it's important to try to keep cool.

    The US Army has created a great "Heat Index calculator" (along with other conversions) that you can use to determine the heat index at your particular location: Weather Conversion Calculators, http://www.eustis.army.mil/weather/weather_products/wxconversions.htm    It's about halfway down the page.

    NOAA's Weather Prediction Center has one on their homepage as well: WPC Heat Index Calculator - http://www.hpc.ncep.noaa.gov/html/heatindex.shtml

    Here is a list of possible heat disorders that could result for people in high risk groups when the HI reaches a certain value: Heat Index of 130F or higher = Heat stroke or sunstroke likely, Heat Index between 105 - 129F = Sunstroke, muscle cramps, and/or heat exhaustion likely, Heatstroke possible with prolonged exposure and/or physical activity. Heat Index between 90 - 105F = Sunstroke, muscle cramps, and/or heat exhaustion possible with prolonged exposure and/or physical activity. Heat Index between 80 - 90F = Fatigue possible with prolonged exposure and/or physical activity.

    For additional information on HEAT visit http://www.nws.noaa.gov/os/heat/index.shtml#heatindex and HEAT STRESS, visit http://www.ncdc.noaa.gov/temp-and-precip/heat-stress.php

    On a final note, animals such as dogs are very susceptible to heat stroke. Don't forget to find a shady, cool spot for your pets. They will be thankful you did.

    Arlington - " THE MONTHLY AVERAGE TEMPERATURE THIS JUNE WAS SLIGHTLY ABOVE THE 1981-2010 NORMAL. THE HIGH TEMPERATURE REACHED 90F DEGREES ON 6 DAYS THIS MONTH... WHICH WAS THE LEAST NUMBER OF 90-DEGREE DAYS IN JUNE SINCE 2 DAYS IN 2009. THERE WERE NO 95-DEGREE DAYS IN JUNE FOR THE FIRST TIME SINCE 2009. NO DAILY TEMPERATURE RECORDS WERE SET THIS MONTH. THE MAIN STORY THIS MONTH WAS THE EXCESSIVE RAIN. REAGAN NATIONAL AIRPORT MEASURED 9.97 INCHES OF RAINFALL THIS MONTH...WHICH WAS THE 4TH WETTEST JUNE ON RECORD. THE ONLY WETTER JUNE ON RECORD WERE 1900 (10.94 INCHES)...1972 (11.53 INCHES) AND 2006 (14.02 INCHES). JUNE 2013 WAS THE 3RD WETTEST MONTH SO FAR THIS CENTURY IN WASHINGTON AND THE WETTEST MONTH SINCE MAY 2008 (10.66 INCHES). MOISTURE FROM TROPICAL STORM ANDREA BROUGHT HEAVY RAINS TO THE AREA ON JUNE 10. THE 2.77 INCHES OF RAINFALL ON THE 10TH SET A DAILY RAINFALL RECORD...BREAKING THE PREVIOUS RECORD OF 2.27 INCHES IN 1945. THE WETTEST DAY THIS JUNE WAS THE 28TH WHEN 2.86 INCHES OF RAIN FELL. IT DID NOT SET A DAILY RAINFALL RECORD THOUGH SINCE 2.95 INCHES WAS RECORDED ON THE SAME CALENDAR DAY IN 1914. " - [ + + ] - from NWS Sterling, VA

    Bridgewater - from Clayton Towers: " Hi folks! Not doing too well. Been in hospital 5 days. Will be 94 in Nov. Might have to give up weather reporting... been with ACON 35-40 years. It's hard to give up things you like to do. Got a lot of hobbies., Take care! Clayton P.S. I have learned a lot about t-storms thru' the years. Listen to static on AM radio. (Editor's note: We hope you're better Clayton. When you get a chance, send us some data! I too used to check the AM radio for static... you could learn a lot just monitoring it... even hooked up a VU sound meter to a radio speaker (earphone mode) and was able to monitor strength and weakness of sound created by lightning bolts. With a storm right at my station the VU meter pegged 100%. Obviously weaker readings meant distant storms. Directions, of course, were not detectable.) " - [ M M ]

    Chantilly - from Russ Topping: " This June was warmer and wetter than average. The mean monthly temperature was 74.5° (+2.1°). The mean high temperature was 83.8° (+0.0°) and the mean low temperature was 65.1° (+4.1°). A record high minimum temp was set on the 2nd (69.0°). Rainfall totaled 5.02", thanks in part to the remnants of TS Andrea. Dense fog was observed on the 27th. Thunderstorms were observed on the 2nd, 9th, 13th, 17th, 28th and 30th. *Please note, anemometer is currently partially obstructed from the North and East " - [ + + ]

    Glen Allen - from Lowell Koontz: " June 2013 was the wettest June on record at the Glen Allen station. The 6.52 inches monthly precipitation was a departure of 3.58 inches. The mean temperature was -1.2°F below average for the past four years but remember two of these years were in the top five of the warmest in recorded history of the Richmond area. June was our wettest month since August of 2011 when 6.65 inches was recorded. Only three months have been wetter at this station since records were started in August of 2009. The Richmond International Airport had 6.50 inches and was their wettest June since 2006 when 7.85 inches was recorded. Glen Allen had 16 days in June with precipitation, which sets a new record for June; the previous record was 14 days. The maximum precipitation recorded in a day was 1.79 inches on the 7th. Thunder was heard on eight days during June tying the record but none of these storms were severe here. June was the second cloudiest month on record with an average relative humidity of 72.7 % a new maximum record for June. This was the highest monthly average relative humidity since September of 2011. These factors helped in giving June the lowest temperature range on record at Glen Allen. The lowest dew point temperature for June was 41.4 °F on the 4th and the highest dew point was 76.5 °F on the 25th. On June 13th and 28th the barometric pressure was 29.51 inches, which is a new record minimum for the month of June. (Records since 2009) The total wind run for June was 1951 miles, which was a new maximum record for June as were the daily average and daily maximum. The maximum wind for the month was only 31 mph on the 28th from the SSW at 1650. " - [ - + ]

On the precipitation side, the month was 1.95” above normal with 6.74” measured. 2.33” came on the 6th and 7th with TS Andrea and another 1.94” came with a heavy TRW on the 10th.
