Today is expected to be the hottest day of the week, with temperatures reaching the mid-90s is some locations that, accompanied by high humidity, will create oppressive conditions, according to the National Weather Service.
The Weather Service has issued a heat advisory for Wyoming County that begins at noon today and will remain in effect until 7 p.m.
Hot temperatures and high humidity, with heat index values in the mid-90s are expected, the Weather Service said.
The advisory also includes Chautauqua and southern Erie counties.

A heat advisory continues until 8 p.m. Friday for Genesee, Livingston, Orleans, Monroe, Ontario, Niagara, northern Erie, Wayne, northern Cayuga and Oswego counties.
Heat index values as high as 100 degrees are possible in those counties today.
High temperatures are forecast to be near 94 degrees today and in the lower 90s on Friday before dipping to the mid-80s on Saturday when a weak cool front slowly works into the region, bringing more widespread showers and storms on Friday and Saturday.
Normal temperatures for this time of year are 80 degrees in the region, according to historical data from the Weather Service.
The combination of hot temperatures and high humidity will combine to create a dangerous situation in which heat illnesses are likely. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.
Anyone overcome by heat should be moved to a cool and shaded location.
Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening.
Wear lightweight and loose fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments.
Hot temperatures and high humidity may cause heat illnesses to occur. Know the signs and symptoms of heat exhaustion and heat stroke.
Muscle cramping is usually the first sign of heat-related illnesses (heat exhaustion or heat stroke).
Symptoms of heat exhaustion include nausea, vomiting, cold/pale/clammy skin, heavy sweating, fast and weak pulse, weakness or fainting and fast and shallow breathing. Victims of this illness should be moved to a cool place, be cooled using any method available such as ice packs; cool, wet cloths, or by applying water to the body, and sip on water. If a victim is continuously vomiting or loses consciousness, call 911 or your local emergency number immediately.
If heat exhaustion is not treated it may progress to heat stroke.
Symptoms of heat stroke include hot body temperature, hot/red/dry/moist skin, rapid and strong pulse and possible unconsciousness. Victims of this illness should be treated in the same ways as those with heat exhaustion but do not give fluids. Also, 911 should be immediately called, as heat stroke is a medical emergency.
