Fireworks weren't the only things launched over the Fourth of July holiday. The mercury shot up on Sunday to signal the start of an old-fashioned summer heat wave. At 5:30 p.m. Sunday, temperatures reached into the mid 90s throughout the area. Here, there is no sign of movement along East Broad Street in Tamaqua as residents either stayed in air-conditioned quarters or headed to the community swimming pool or nearby state parks. The heat will continue this week, potentially close to 100 degrees Tuesday and Wednesday.
