| episode_narrative | Another strong and oppressive ridge of high pressure gave the Poconos three days and the rest of Eastern Pennsylvania four days of oppressive heat and humidity and five consecutive days with high temperatures in the 90s. High temperatures reached into the 90s again on the 15th after several days of unseasonably cool weather. The air mass initially was relatively dry. Southwest winds continued to increase humidity levels. The combination of the temperature and humidity produced heat indices of around 100 degrees during the afternoon of the 16th and around 105 degrees during each afternoon from the 17th through the 19th. The hottest part of this air mass passed over northern parts of the Middle Atlantic States. Thus some of the highest temperatures occurred well north of the Pennsylvania/Maryland border. This hot spell produced higher temperatures in the Poconos than the hot spell over the Independence Day Holiday Weekend. A weak backdoor cold front moved south through the region during the evening of the 19th. While the air mass was not considerably drier on the 20th, skies were cloudy as the front stalled near the area. Drier air worked its way north to south across the area during the afternoon and evening of the 20th. As a high pressure system built into New England on the 21st, dry air briefly covered the area. Once again health officials issued Code Reds, opened up hotlines and tried to assist the elderly the best they could. No heat related deaths were reported. The excessive heat and the lack of rain continued to decimate non-irrigated farms across the state. Milk production was also affected and statewide was down about 20 percent for the month of July. The high temperatures again put a strain on electrical utilities. For the second time this month, on Monday July 19th the PJM Interconnection Association called for a 5 percent reduction in voltage from 115 p.m. EDT through 210 p.m. EDT. PECO Energy requested large industrial users to conserve electricity. PECO Energy reported the second highest energy usage on record on the 19th. On July 17th, the 6,856 megawatts of power set a new weekend record for PECO. The highest temperatures during this hot spell were scattered from the 17th through the 19th. They included 100 degrees in East Stroudsburg (Monroe County), Easton (Northampton County), Hamburg (Berks County), New Hope (Bucks County), Perkasie (Bucks County), Reading (Berks County) and Valley Forge (Chester County), 99 degrees at the Lehigh Valley International Airport, Pottstown (Montgomery County), the Franklin Institute within Philadelphia and Doylestown and Sellersville in Bucks County, 98 degrees at the Philadelphia International Airport and the Northeast Philadelphia Airport, 97 degrees at the Willow Grove NAS (Montgomery County) and Hopewell Village (Berks County), 96 degrees in Avoca (Luzerne County), 95 at the F.E. Walter Dam (Carbon County) and 93 degrees in Long Pond (Monroe County). Due to higher historical daily maximum temperature records, fewer daily high temperature records were set. But, the high of 99 degrees at the Lehigh Valley International Airport set a new daily record high for the 17th. |
