Temperatures to creep close to 100 during heat wave

June 29, 2018 GMT

Residents can expect at least a week of hot and humid days, with the heat index in the 90s.

Despite how hot it will get, the National Weather Service is just several degrees shy of declaring a heat advisory for this weekend.

“The heat is going to get uncomfortable,” said Mike Kennedy, a meteorologist with the National Weather Service in Moon Township.

High humidity coupled with soaring temperatures in the lower 90s will add up to a heat index e_SEmD what temperatures feel like — in the upper 90s starting Sunday, according to Kennedy.

The region is already under an air quality alert for unhealthy ozone Friday, which is expected to last into the weekend. Some residents are urged to limit their time outdoors including young children, the elderly and those with respiratory problems.

Kennedy says the weather service could issue a heat advisory for Monday or Tuesday as the index could top 100 degrees.

The advisory is a public alert that people’s heath can be impacted by the heat. The advisory can trigger other actions such as the regulation of power and changing outdoor work requirements.

A ridge of high pressure is blanketing the Northeast and isn’t expected to go away anytime soon, according to Kennedy.

Temperatures will start to climb on Friday with highs in the upper 80s. Saturday’s heat index will rise from the low- to mid-90s. Come Sunday, the heat index will inch up to the upper-90s, according to the National Weather Service’s forecast for the region.

For Monday and Tuesday, the heat index could break 100 degrees.

High temperatures are forecasted to persist until at least Thursday.

Typical highs for the region this time of year are in the low 80-degree range, according to Kennedy.
