It's going to be hot. Real hot.
A heat wave is expected to see temperatures in the mid-90s combining with dew points in the mid-70s to create a sticky, humid week that will stretch on into the weekend. The heat index is expected to climb to as high as 109 degrees in some areas.
The National Weather Service in Philadelphia/Mount Holly says that the highest heat index values will occur mid day, though there won't be much relief during the overnight hours. Excessive heat will also be possible starting again Friday though the weekend.
Here are a few tips from the National Weather Service about how to deal with the extreme heat:
"Take extra precautions, if you work or spend time outside. When
possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing when possible and drink plenty of water. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency, call 9 1 1."
