A mid-summer heat wave begins today and is expected to last through Friday or Saturday, with heat index values expected to reach and exceed 100 degrees during certain portions of the week, according to the National Weather Service.

The service issued a Heat Advisory for multiple counties in New Jersey and Pennsylvania, including Middlesex County, from noon to 8 p.m. Monday night.

Heat indices are expected to reach between 102 due to temperatures in the 90's. 

The highest heat indices are expected between 2 and 6 p.m. each of the next three days, according to the NWS forecast. Temperatures are expected to reach into the 90's.

Later in the week, the heat is expected to intensify, with the highest heat indices reaching 105 degrees on Thursday and Friday afternoons, according to the forecast.

Conditions will be dangerous for those working outside or living in non-air conditioned homes. Young children and adults over 50 are expected to be adversely impacted, and leaving anyone in non-air conditioned cars, including children and pets, can be fatal, the NWS warns.

NWS advises residents to drink plenty of fluids, stay out of the sun, stay in air conditioned rooms and check up on relatives and neighbors.

Those who must work outside are advised to do so in the early morning or evening hours, wear light weight and loose fitting clothing, drink plenty of water and be aware of the signs and symptoms of heat exhaustion. It also advises scheduling frequent rest periods in shaded or air conditioned environments. Anyone overcome by heat should move to a cooler location, and anyone suffering heat stroke should call 911.
