PITTSBURGH (KDKA) — Clouds have kept temperatures very mild through the overnight hours ahead of a system that will bring the Pittsburgh area’s long-awaited rain chance on Sunday.
Most of Western Pennsylvania is dry before sunrise, but some areas of rain are showing up on radar across eastern Ohio. Initially, as the precipitation moves into the area, we may have some issues with evaporation on the way down to the surface due to a pretty deep layer of dry air, but eventually, that layer will become saturated and by mid-morning to midday, rain will commence.
A steady rain is expected through 5 to 6 p.m. Sunday evening with more showery activity into the evening and overnight hours. We cannot rule out a thunderstorm or two as there will be some instability present, but no severe weather is expected.
Total rainfall amounts will range from a half-inch to locally over 1 inch with a majority of folks receiving between a half-inch to three-quarters of an inch. This would be the most rain in a single event since Oct. 6 for Pittsburgh.
