Dry skies and sunshine will return to end the weekend across Pittsburgh, but not before Sunday starts with patchy fog and clouds. The clouds are expected to break in the afternoon, giving the region a brighter finish to the day.
Sunday will be seasonal, with a high of 64 degrees and a low of 44 degrees. That sets up a milder start to next week, when temperatures rebound into the 70s and dry weather holds through Monday.
Monday is shaping up to be the nicest day in the stretch, with sunshine, milder temperatures, a high of 71 degrees and a low of 52 degrees. The calm pattern does not last long. A few showers are expected to move through on Tuesday, with a high of 70 degrees and a low of 55 degrees, followed by another round of showers on Wednesday.
Temperatures then trend cooler by the end of the week. For Pittsburgh Marathon weekend, morning readings are expected to be around 40 degrees, with daytime temperatures in the 50s. That means runners and spectators will need warmer layers early, even as the afternoons stay manageable.
The forecast leaves Pittsburgh with a brief run of dry, sunny weather before rain chances return Tuesday and Wednesday, then a cooler finish to the week. For now, the answer is simple: Sunday and Monday are the best days in the stretch, and the warmer stretch gives way to a wetter midweek.
