Temperatures along a line from Beaver Falls-Pittsburgh-Greensburg and points southwest are already above freezing just before sunrise, so freezing precipitation will not be a big deal today for most of metro pittsburgh and points to the southwest.

Areas north of Highway 422 toward I-80 and in the Laurel Highlands are still hovering around and just below freezing, so as precipitation moves in around 8-9 in the morning, the start will consist of a short period of freezing rain for the places that can lead to a light glaze of ice on untreated surfaces.

By early afternoon, the freezing line will have moved north, likely past the I-80 corridor, but will still be hung up in the Laurel Highlands, and this is where higher ice accumulations along with a smaller snow accumulation (in the highest peaks) will be possible.

Between 0.10″ to 0.25″ of ice will be possible for parts of Jefferson, Indiana, Somerset, Preston and Garrett counties along with a few inches of snow. A winter storm warning is in effect at 4 Monday for Somerset County and at 7 Monday for Garrett County.

By Sunday evening and overnight Monday, most of our area will be well above freezing with persistent areas of showers and some light rain Monday morning. Warmer air will continue to flow in from the southwest ahead of another disturbance and its associated cold front.

This will result in highs reaching the low to mid 50s Monday night. This warming will be accompanied by widespread rain beginning Monday afternoon and lasting until just after midnight Tuesday morning. Tuesday’s high will also occur early in the morning with stable and falling temperatures for the rest of the day along with clear skies.

Tuesday night into Wednesday morning will be dry, but clouds will increase throughout the day Wednesday with another round of showers in the afternoon and evening. Some snow is possible to end this event Thursday morning as colder air moves in behind the cold front.

Expect temperatures to be largely below average by the end of the coming week. Another low pressure system will swing in from the northwest on Friday, bringing another chance for a few snow showers along with another wave of cold air. This cold air is likely to persist through the coming weekend and just before Christmas before a warmer pattern sets in.
