| episode_narrative | High pressure centered over the Southeast U.S. caused air to downslope over the Appalachian Mountains, sending afternoon temperatures into the upper 90s to lower 100s. The heat, in combination with very humid air, resulted in afternoon heat indices between 100 and 110 degrees. Dupont Circle in Northwest Washington reported a high temperature of 100 degrees on the 7th, 8th, and 9th. The high temperature at Washington Reagan National Airport on the 7th was 98 degrees, which broke a record high of 97 degrees set in 1899. The high at National Airport on the 8th was 98 degrees, which also broke a record high of 97 degrees set in 1899. George Washington University reported a high temperature of 99 degrees on the 8th. The mercury climbed to 98 degrees again at National Airport on the 9th, but failed to break the record high of 102 degrees set in 1874. Nighttime lows only dipped into the upper 70s, making the overnight hours very uncomfortable for those without air conditioning. As a result of the heat, a pollution alert was issued for the Washington D.C. metropolitan area on the 7th, and D.C. authorities opened 5 "cooling shelters" for area residents during the heat of the day. Schools in the District cancelled classes on the 8th and 9th because many buildings did not have air conditioning. Low water pressure was reported in parts of Northeast Washington near the Anacostia River on the 8th and 9th, and was attributed to the high use of water during the unusually warm period. |
