SUMMARY OF CLIMATOLOGICAL DATA 


JUNE 2011


...CONTINUED ABOVE NORMAL TEMPERATURES...
...CONTINUED BELOW NORMAL RAINFALL...



  •   1981-2010 NORMALS    From Kevin Shaw: " At long last, based on a great tip from my friend Rick Thoman up in Alaska, here is a one stop shop for basic 1981-2010 normals information: http://ggweather.com/normals/index.htm. Also, I happened to find this one myself, covering a lot of links to record information: http://illiniweather.com/pages/weather_record_links.htm.


  • CLOSE CALL WITH LIGHTNING CAUGHT ON CAMERA    Check out this link to footage of a nearby lightning strike (submitted by Member Lowell Koontz): http://www.nwitimes.com:80/video-photo-galleries-audio-interactives/video/vmix_a5a81690-4f54-5d23-905d-ba47e3efb0bb.html


  • WEATHER SYMBOLS - WHAT'S THAT "S" WITH THE ARROW THROUGH IT?    (From the CoCoRaHS website:) Those of you interested in weather will want to learn the 100 weather symbols used today in meteorology. You might recognize some of the more common ones and there will be others that are unfamiliar. Here is a great list of those symbols by the National Weather Service's JetStream - Online School for Weather. Click here: Weather Symbols. Weather symbols have been used by meteorologists for many years on surface weather maps, often seen at station weather plots. Click here: Weather Maps. So the next time you see a comma or set of periods you might think punctuation, but than again you just might think precipitation! By the way, that "S" with the arrow through it . . . that's a moderate dust storm.


  • WANTED: YOUR QUESTIONS    Wanted: Questions for the "Weather Queries" column in Weatherwise Magazine As you go out each morning to take a look at your rain gauge, or any other time you're outdoors, do you ever puzzle about what's going on in the sky? Do you wonder about spells of unusual weather? If you have a question about weather or climate, send it to: weatherqueries@gmail.com. Tom Schlatter, a fellow CoCoRaHS volunteer, has been writing a question and answer column in Weatherwise since 1980, and he welcomes questions from young and old. No question is too simple. In fact, sometimes the "simple" questions are the most profound. Send your questions to weatherqueries@gmail.com, and be sure to include your name and the city or town where you live.


  • "ASK JACK AT  USA TODAY"
  •    Kevin Shaw of ACON MD/DE/DC sends another resource. It is a neat webpage that will help you find specific historical weather info for the United States and even in some cases, the world! The source is organized by Jack Williams and the USA Today weather page. View here: http://www.usatoday.com/weather/resources/askjack/wfaqpast.htm.

  • 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/
