Complex winter storm to bring mix of snow, freezing rain, sleet and rain by Thursday

PITTSBURGH — A complex winter storm will bring a mix of snow, freezing rain, sleet and rain to the area into Thursday.

A few light snow showers will break out during the day Wednesday, but the steadier shield of winter weather won’t move in until overnight Wednesday night.

Temperatures during the day Wednesday will climb above freezing so any snow that falls will melt leaving roads mainly wet.

Colder temperatures after dark will set the stage for a wintry mix of light snow, freezing rain and possibly sleet around midnight. A light glaze of ice from I-70 north could develop by 5 a.m. leaving roads and sidewalks slick. It is also possible that some areas see a switch from freezing rain to rain over a short distance so plan for quickly changing road conditions and hazardous travel.

Colder temperatures north of Rt 422 and east in the higher elevations of Westmoreland, Fayette and Indiana counties will allow more ice to form and could create the threat for downed trees and power lines.

Warmer air will change the wintry mix to rain through the morning for most areas but delays to the morning commute will be possible.

A Winter Weather Advisory has been issued from Washington County north and east to the higher elevations where an Ice Storm Warning has been issued.

This is a complicated system, and the forecast will change so stay with thr Severe Weather Team 11 for the latest updates and have the Severe Weather Team 11 app for alerts, watches and warnings.
