What we’re tracking for Friday

Temperatures may not get out of the 30s on Friday. If enough moisture is leftover, we will at least see a rain/snow mix Friday morning. The Laurel Highlands have a greater chance of seeing all snow, and some of that snow may also stick. At this point, accumulations look light, but we will be monitoring this as we get closer.

Model disagree on the coverage of Friday’s snow. The greatest chance is for the Laurel Highlands.

We stay cold on Saturday and more flakes are not completely out of the question.

Pittsburgh’s average first measurable snowfall typically occurs in mid-November. Limited moisture and “warm” ground temperatures could keep the flakes from sticking.

Details on the wintry changes will become clearer by the day. Stay with the Pittsburgh’s Action Weather team for the latest forecast updates.
