Pittsburgh woke to fog and mist Thursday, with temperatures near 48 degrees before a much sunnier afternoon. The haze should fade after sunrise, making way for one of the warmest days of the week and a high near 74.

South winds will stay fairly light, while rain chances remain essentially nonexistent during the day. The latest National Weather Service update keeps the region warm through Thursday, building on Hoodline's earlier forecast while adding more detail about the weekend shift.

Fog Gives Way To A 74-Degree Thursday

Thursday night will remain mild, with partly cloudy skies and a low around 54 degrees. That is a comfortable setup for evening plans, although the skies will become less clear as a weak front approaches.

Friday will still be pleasant overall, with mostly sunny skies and a high near 67 degrees. A small chance of spotty light rain or drizzle arrives early Friday, especially north of Interstate 70 and along the ridges, before drier weather returns later in the morning.

Halloween Weekend Stays Mild And Mostly Dry

Friday night turns noticeably cooler, dropping to around 40 degrees under partly cloudy skies. Saturday, Halloween, should be quiet and dry, with low-60s temperatures for trick-or-treating, followed by a mostly cloudy night and a low around 46.

Sunday stays mild for the season, reaching close to 69 degrees beneath mostly cloudy skies. A slight chance of showers could develop late Sunday night, with the chance lingering into Monday morning before temperatures climb near 68.

Rain Remains Possible Later In The Week

A possible system could bring rain later in the week, though the forecast remains uncertain.
