Pittsburgh, PA – Western Pennsylvania residents are facing a sharp contrast in fall weather Monday, Oct. 19, as a frost advisory threatens sensitive outdoor plants before sunshine sends temperatures into the middle 60s. Looking farther ahead, federal forecasters favor warmer than normal conditions across much of Pennsylvania as October ends and November begins.
According to NOAA's Climate Prediction Center, the eight to 14 day outlook issued Oct. 18 covers Monday, Oct. 26, through Sunday, Nov. 1, 2026 . The temperature map places Pennsylvania within a broad region favoring above normal temperatures, while the precipitation outlook indicates a tendency toward below normal precipitation. The extended pattern is separate from Monday morning's frost advisory.
Frost Advisory Covers Pittsburgh and Surrounding Counties The National Weather Service in Pittsburgh issued a frost advisory for portions of far southwestern Pennsylvania, eastern Ohio and northern West Virginia.
The advisory remains in effect from 1 a.m. until 9 a.m. EDT Monday, Oct. 19 , with temperatures potentially falling as low as 33 degrees.
Affected Pennsylvania communities include Pittsburgh, Washington, Canonsburg, Monessen, Greensburg, New Kensington, Aliquippa, Beaver Falls, Waynesburg and surrounding areas.
According to the Weather Service, frost could harm sensitive outdoor vegetation, and tender plants may be killed if left uncovered.
Residents with vulnerable flowers, gardens or other sensitive plants are encouraged to take precautions during the early morning hours.
Although temperatures may remain slightly above freezing in some communities, frost can still develop on exposed surfaces when conditions allow.
The advisory does not indicate that every location will reach 32 degrees.
Pittsburgh Forecast Calls for Sunshine and 60 Degree Highs Despite the chilly start, the National Weather Service is forecasting a stretch of mostly sunny weather across Pittsburgh.
Monday is expected to be sunny after areas of frost before 9 a.m., with temperatures reaching approximately 65 degrees.
Tuesday brings mostly sunny skies and a high near 66 degrees, followed by a mostly clear night with temperatures falling to around 38 degrees.
Wednesday is forecast to be sunny with a high near 64 degrees, while Thursday should reach approximately 65 degrees.
Friday is expected to be sunny with a high near 63 degrees.
Weekend temperatures remain similar, with Saturday reaching around 64 degrees and Sunday near 65 degrees.
Overnight lows generally remain in the upper 30s to lower 40s.
These daily forecasts apply to Oct. 19–25 and should not be interpreted as specific temperatures for the later Oct. 26–Nov. 1 outlook.
Above Normal Warmth Favored Into November NOAA's extended temperature outlook places much of Pennsylvania within an area favoring above normal temperatures.
Western Pennsylvania, including the Pittsburgh region, appears within a relatively strong temperature signal, with probabilities approximately 60% to 70%.
Farther east, above normal temperatures are also favored, although the strength of the signal varies across the state.
The precipitation outlook favors below normal totals across much of Pennsylvania, generally with probabilities around 33% to 40%.
This does not guarantee a rain free week or unusually warm temperatures every afternoon.
Instead, the outlook indicates that average temperatures during Oct. 26–Nov. 1 are more likely to exceed historical norms, while total precipitation is more likely to fall below normal.
For Pittsburgh residents, the contrast between Monday's frost advisory and the extended warming signal highlights the variability of autumn weather.
Updated forecasts will clarify whether the milder pattern produces noticeably warmer afternoons or simply keeps temperatures above seasonal averages.
