PITTSBURGH (KDKA) – A very complicated system will move through the area Thursday evening bringing a bag of mixed precipitation.

ALERT: Hazardous weather is coming just around the evening drive with snow north of I-80. Freezing rain is expected along the ridges and north of Pittsburgh, and heavy rain is expected south of Interstate 70. A winter weather advisory begins for counties north of Pittsburgh at 6 p.m. and a storm warning sleet begins at 5 p.m. for the Ridges and Laurels.

AWARE: The flood advisory for the Ohio River at the tip (downtown Pittsburgh) lasts through Monday morning. The river is expected to peak at 20.5′ Saturday morning. Part of the Mon Wharf will be completed with parts of the North Shore River Walk.

Everything seems to be staying on track with the winter storm system moving through our area. Although this is a winter storm, snow is not a big part of it for us. Heavy rain will fall from Pittsburgh south.

North of the city, a winter mix will last for several hours before turning into rain. The ridges are likely to have the greatest impacts with significant freezing rain. Remember that freezing rain is the icy glaze, which could lead to power outages and dangerous overnight travel conditions.

North of Pittsburgh, where we have the winter weather advisory, some shifting slicks are possible in places, but the rain will eventually spread north towards I-80.

In and south of Pittsburgh, heavy rain is likely. Some places could receive more than an inch of rain. The ground is still saturated after some heavy rains last week, so flooding will become possible, especially in flood-prone, low-lying and poorly drained areas.

Friday morning’s trip will bring light snow showers, but there will be virtually no accumulation. Watch for slippery spots with puddles on the roads and even flooding in low areas. It will only be in the mid-20s for daytime temperatures on Friday, so a refreeze is also possible.

The weekend will be calm, with cold mornings and mostly sunny afternoon skies with highs in the mid-30s on Saturday and near 40s on Sunday.
