As a relentless heat wave advances, the Midwest and Northeast are gearing up for potentially the hottest weather in three decades. The heatwave is fueled by an unrelenting “heat dome”, which occurs when a persistent region of high-pressure traps heat over a particular area, and it can linger for days to weeks. With temperatures soaring, health officials are emphasizing the need for additional precautions, noting that extreme heat poses significant health risks. According to the NWS, heat ranks as the number one weather-related killer in the U.S.

As of Tuesday afternoon, the NWS has issued a Heat Advisory for central Pennsylvania, effective until 8 PM EDT Friday. Forecasters are projecting Heat index values up to 100 throughout the region, scattered showers and thunderstorms, and near-record high temperatures of 90+ degrees into the weekend.

Two records were either set or tied for sites today:

A record high temperature of 92 degrees was set at Altoona today that ties the old record of 92 degrees set back in 1994. A record high temperature of 90 degrees was set at Bradford today that breaks the old record of 87 degrees set back in 1993.

Here are some important reminders and recommendations:

  • Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors.
  • Do not leave young children and pets in unattended vehicles. Car interiors will reach lethal temperatures in a matter of minutes.
  • Take extra precautions when outside → Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. 
  • Take action when you see symptoms of heat exhaustion and heat stroke.
  • Monitor the latest forecasts and warnings for updates.

Power outages could occur due to a prolonged period of heat. Residents can check Pennsylvania 211 for an extensive list of cooling centers across the state.
