TRANSCRIPT OF AUDIO

From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of January 14, 2019.

This week, we feature a sound-and-music medley for a weather-and-water mystery.   Have a listen for about 25 seconds, and see if you know what kind of weather record was broken in 2018 in several locations in Virginia.

SOUNDS and MUSIC - ~18 sec

If you guessed precipitation or rainfall, you’re right!  You heard a Blacksburg, Va., thunderstorm, along with part of “Rain in the Valley” by The Steel Wheels, from Rockingham County, Va.   In 2018, annual local records for total precipitation—that is, rainfall plus the water equivalent of frozen precipitation—were broken in five National Weather Service observation locations in Virginia: Danville, Lynchburg, Roanoke, Reagan National Airport in Arlington County, and Dulles Airport in Loudoun County.  And Richmond’s Weather Service observation location experienced the second-highest annual precipitation on record.  Records at those locations go back to the early 1900s or late 1800s, except for the Dulles Airport location, where records go back to 1960.  Those six locations had over 60 inches of precipitation in 2018, compared to normal annual values of around 40 to 45 inches for most locations in Virginia.

At six other Weather Service observation locations covering parts of the Commonwealth, precipitation in 2018 didn’t break records but still ranged from about seven inches above normal at Wallops Island in Accomack County to nearly 20 inches above normal at the Charlottesville-Albemarle County Airport.  Beyond Virginia, across the eastern and Midwestern United States, annual precipitation records were broken in nearly 200 locations in 2018, according to Ian Livingston of The Washington Post’s Capital Weather Gang.

Besides official National Weather Service observation locations, Virginia has over 1000 weather-observation stations participating in the Community Collaborative Rain, Hail, and Snow Network of volunteer weather observers.  If you live in the Commonwealth, a station near you may also have seen record precipitation in rainy 2018.

Thanks to The Steel Wheels for permission to use this week’s music.  We close about a bit more music for precipitation; here’s part of “Rain Refrain,” composed and performed for Virginia Water Radio by Torrin Hallett, a 2018 graduate of Oberlin College and Conservatory in Oberlin, Ohio.

MUSIC - ~29 sec

SHIP’S BELL

Virginia Water Radio is produced by the Virginia Water Resources Research Center, part of Virginia Tech’s College of Natural Resources and Environment.   For more Virginia water sounds, music, or information, visit us online at virginiawaterradio.org, or call the Water Center at (540) 231-5624.  Thanks to Stewart Scales for his banjo version of Cripple Creek to open and close this show.  In Blacksburg, I’m Alan Raflo, thanking you for listening, and wishing you health, wisdom, and good water.

EXTRA FACTS ABOUT PRECIPITATION IN VIRGINIA IN 2018

Following are some details on precipitation in 2018 at 12 National Weather Service (NWS) observation locations in or adjacent to Virginia.  All values are in inches. The information in this section is from the following sources:

According to the NWS, as of January 2019 precipitation values from 2018 are still preliminary; that is, they haven’t undergone final quality control by the National Climatic Data Center (NCDC) and therefore are subject to revision.  Final, certified climate data are available from the NCDC online at http://www.ncdc.noaa.gov.”  Normal values currently used by the NWS are based on the period from 1981 to 2010.  The NCDC released these normal values in July 2011. For information on the normal values, see the NCDC Web page at http://www.ncdc.noaa.gov/data-access/land-based-station-data/land-based-datasets/climate-normals.
