Pittsburgh is starting Saturday with chilly temperatures, gusty north winds and a few scattered rain showers before 9 a.m. The clouds should break for a mostly sunny afternoon, but the high will reach only about 53 degrees. Then comes a sharp overnight chill, with temperatures falling to around 31 degrees by early Sunday.
Freeze Warning Arrives Sunday Morning
The National Weather Service in Pittsburgh has issued a Freeze Warning from 1 a.m. to 9 a.m. Sunday, with temperatures expected to drop into the upper 20s to around 30. The agency warns that frost and freezing conditions could kill crops and other sensitive vegetation.
Residents with tender plants should bring them indoors or cover them before Saturday night. The coldest stretch arrives under clear skies and light winds, which will make it easier for temperatures to plunge.
Sunshine Returns After The Cold Snap
Sunday morning frost should fade by about 10 a.m., followed by sunny skies and a high near 60. The warming trend continues Monday with a high around 66, then reaches the upper 60s from Tuesday through Friday.
Tuesday and Wednesday should top out in the mid-60s, Thursday near 69 and Friday near 74. Mostly sunny skies are expected through Thursday. That is a considerably calmer outlook than the storm-and-cold setup described in Friday's Hoodline forecast, though the freeze threat has now become the weekend's main concern.
Saturday Winds Ease By Evening
North winds of 10 to 15 mph will keep Saturday feeling colder than the thermometer suggests, then gradually weaken Saturday evening. The freeze warning expires Sunday morning.
For outdoor plans, Saturday afternoon offers the better window, while gardeners should treat Saturday night as a plant-protection deadline. Once Sunday afternoon arrives, Pittsburgh gets a long, dry run of sunshine and warmer afternoons.
