Thursday begins on a very warm and smoky note across most of Western Pennsylvania and Northern West Virginia. Wildfire smoke and haze have mixed down to this surface, resulting in code yellow to code orange air quality, meaning that the condition of the air is unhealthy for those with any underlying health conditions.

Smoke from Canadian wildfires will continue to give us a hazy sky over the next couple of days. No air quality alert has been issued; however, those who are unusually sensitive to respiratory ailments should limit overexertion outside this afternoon and evening.

Humidity starts to creep up on Thursday, as dew points return to the low 60s. It will be warmer, with highs in the mid-to-upper 80s. Friday will be warm and sticky. Highs will reach 84 degrees under partly sunny skies. A few showers are possible in the afternoon and evening, as a weak cold front drops across Pennsylvania.

Smoke from wildfires raging in Canada has drifted into the United States, affecting air quality as far south as Florida.

Temperatures will jump into the upper 80s and humidity will also be on the rise, making it feel a few degrees hotter.
