An Excessive Heat Warning is in effect for Philadelphia and immediate surrounding counties through at least Friday night as temperatures are expected to again soar into the 90s.
Highs are expected in the mid-90s in the city and suburbs Tuesday as the sweltering conditions continue. There's little relief in sight: The National Weather Service says the high pressure system that's bringing the heat is expected to remain in place until Friday.
The hottest part of the day will occur between 1 p.m. and 6 p.m. through Friday. This is a good time of day to seek shade and air conditioning if possible.
Daily high temperatures in the mid to upper 90s will combine with the humidity to make it feel like 105 degrees, according to the National Weather Service.
Forecasters say the excessive heat may linger into Saturday. Relief in the form of showers and thunderstorms is expected later Saturday. Cooler temperatures are expected to arrive on Sunday.
In Philadelphia, Health Commissioner Donald F. Schwarz signaled the activation of the City’s special summer heat programs which include the operation of the Philadelphia Corporation of Aging’s Heatline.
The city’s Heatline will be open from noon until midnight on Monday and from 8:30 a.m. to midnight Friday. You can call the Heatline at 215-765-9040. The Heatline could possibly extend as temps remain high.
Residents are urged to visit older friends, relatives and neighbors to make sure that air conditioners or fans are working and homes are properly ventilated.

Breaking news and the stories that matter to your neighborhood.
Older people with pre-existing medical conditions are especially vulnerable during a heat wave. Other groups at risk are people with chronic medical conditions, pregnant women, small children, those who work in a high heat environment and those who are engaged in a strenuous physical activity.
If you don’t have air conditioning in your home, you should seek relief from the heat for at least some part of the day -- especially in the afternoon when it feels the hottest -- whether it be at a shopping mall, movie theater, senior center or any air conditioned public space. The Health Department also recommends the following to people of all ages in order to avoid a heat-related illness:
- Avoid working or playing in the hot sun or other hot areas
- If you must be out in the sun, wear a head covering
- Use air conditioners and fans
- Open windows to release trapped hot air
- Consult with your physician if you’re taking regular medication. Some medications cause an adverse reaction to hot weather
- Wear lightweight clothing
- Drink plenty of non-alcoholic liquids, warm or cool
- Maintain a normal diet
- Shower or bathe in water that is near skin temperature
- Don’t leave older people, children or pets alone in cars
