An area of low pressure will slide through our area overnight, bringing a chance for some rain. Ahead of the system passing through, we will see a push and pull of warm and cool air along a warm front in our region, keeping us foggy in the morning and cloudy in the afternoon.

We should finally see some breaks in the clouds on Saturday. The push and pull of the front also means a hodgepodge of temperatures, with most places from Pittsburgh to the north seeing highs in the upper 40s and places south of Pittsburgh seeing highs in the low 50s. I have noon temperatures in the mid-40s.
