Pittsburgh is starting Monday under cloudy skies with temperatures in the upper 50s, but the gray setup is the opening act for a much warmer stretch. The city should reach about 69 degrees this afternoon, with light northwest winds and almost no chance of rain.

Clouds Hold Monday Before Fog Arrives

Clouds are expected to linger through Monday evening as temperatures fall to around 57 degrees. Areas of fog may develop after 9 p.m., especially overnight and toward Tuesday morning, so early drivers could encounter pockets of reduced visibility.

No watches, warnings or advisories are listed for the Pittsburgh area, according to the National Weather Service in Pittsburgh. The forecast remains mostly dry through Thursday, giving the region a welcome break from the wetter pattern that has shown up in several recent outlooks.

Sunny And Warmer Through Thursday

Tuesday begins with areas of fog before turning partly sunny and warmer, with a high near 75 degrees. Another round of fog is possible Tuesday night, followed by mostly sunny skies and a high near 78 on Wednesday.

Thursday looks like the warmest day of the week, with mostly sunny conditions and a high near 82 degrees. That is a notable upgrade from the cooler, cloudier start to the week, and the latest outlook is warmer and drier through Thursday than the forecast covered in Hoodline’s Saturday update.

Rain Chances Return Late Week

The pattern turns unsettled Thursday night, when rain showers become possible after 2 a.m. Friday. Friday carries a 50% chance of showers with a high near 72, while additional shower chances remain in the forecast Saturday and Sunday.

Weekend temperatures should be milder than Monday but cooler than Thursday, with highs near 68 Saturday and 69 Sunday. Outdoor plans may still work out, but the forecast increasingly favors keeping a rain jacket nearby as the week winds down.
