Winter Weather Advisory issued for Saturday night due to freezing drizzle, Winter Storm Watch into effect Monday

PITTSBURGH — A Winter Weather Advisory is in effect until 4 a.m. Sunday due to the threat of freezing rain and freezing fog. A light glaze of ice will be possible on untreated surfaces. Temperatures overnight will fall to near 20 degrees with light winds.

Valentine’s Day will bring a mostly cloudy sky with highs in the upper 20s so bundle up if you’re heading out for lunch.

A Winter Storm Watch will go into effect at 1 a.m. Monday and continue until 1 p.m. Tuesday for Pittsburgh and points north and west, including Washington County. Two rounds of precipitation are expected.

The first wave of snow will develop early Monday morning before sunrise, bringing the threat of a trace to three inches of snow. The lesser amounts will be across Fayette County and the higher amounts will be across our northwest counties.

The second wave, which could include a bit of freezing rain, rain or sleet south of I-70 will move in Monday evening into Tuesday. This is where we look to pick up the bulk of our snow accumulation. Right, Pittsburgh is expected to see all snow, but you’ll want to keep checking back. Snow totals will drop off as you travel into parts of Greene and Fayette counties where mixed precipitation is expected.

Stay with our team of meteorologists as we break down the track, timing, precipitation type and totals as this system develops through the weekend.
