Dangerous heat will hit Southwestern Pennsylvania on Friday and Saturday.

The National Weather Service has issued a heat advisory that starts at noon Friday and runs through 8 p.m. Saturday.

It’s been seven years since the National Weather Service in Pittsburgh has issued a warning for excessive heat. That was on July 8, 2012.

The heat index will be up to 104 degrees, caused by temperatures in the lower 90s and dew points in the lower 70s.

The high temperature Friday and Saturday is forecast to be 93 degrees. The record for those days are 97 and 100, respectively, set in the 1800s, National Weather Service meteorologist Myranda Fullerton said.

Nighttime lows will also be high in the mid-70s, again because of the high dew point and humidity, she said — about 10 degrees above average.

The heat and humidity may cause heat stress during outdoor exertion or extended exposure. Residents are advised to reschedule strenuous outdoor activities to early morning or evening, and to be alert for the signs and symptoms of heat exhaustion and heat stroke.

It is also suggested to wear light weight and loose-fitting clothing and drink plenty of water.

After this hot weekend, relief is expected next week. Temperatures are actually expected to be below average, with highs in the upper 70s to 80s, Fullerton said.

We moderate comments. Our goal is to provide substantive commentary for a general readership. By screening submissions, we provide a space where readers can share intelligent and informed commentary that enhances the quality of our news and information.

While most comments will be posted if they are on-topic and not abusive, moderating decisions are subjective. We will make them as carefully and consistently as we can. Because of the volume of reader comments, we cannot review individual moderation decisions with readers.

We value thoughtful comments representing a range of views that make their point quickly and politely. We make an effort to protect discussions from repeated comments either by the same reader or different readers

We follow the same standards for taste as the daily newspaper. A few things we won't tolerate: personal attacks, obscenity, vulgarity, profanity (including expletives and letters followed by dashes), commercial promotion, impersonations, incoherence, proselytizing and SHOUTING. Don't include URLs to Web sites.

We do not edit comments. They are either approved or deleted. We reserve the right to edit a comment that is quoted or excerpted in an article. In this case, we may fix spelling and punctuation.

We welcome strong opinions and criticism of our work, but we don't want comments to become bogged down with discussions of our policies and we will moderate accordingly.

We appreciate it when readers and people quoted in articles or blog posts point out errors of fact or emphasis and will investigate all assertions. But these suggestions should be sent via e-mail. To avoid distracting other readers, we won't publish comments that suggest a correction. Instead, corrections will be made in a blog post or in an article.
