The National Weather Service cautioned drivers in eight Western Pennsylvania counties, including Allegheny, about possible icy roads today from snow squalls.

A special weather statement issued shortly before noon said a squall moving from Ohio could affect northwestern Washington and western Allegheny counties with reduced visibility and hazardous road surfaces.

A subsequent statement reported a squall moving across Beaver County toward Allegheny and Washington counties, including Carnegie and Canonsburg.

An earlier statement for Butler, Lawrence, Mercer and Venango counties to the north of Pittsburgh and Fayette and Greene counties to the south said bands of snow showers can melt and refreeze on roads and create visibility problems. Similar weather last weekend contributed to multi-vehicle pileups on Interstate 79 and Interstate 80.

This afternoon, the advisory was lifted for Fayette and Greene but extended to Clarion and Armstrong counties as hit-and-miss snow showers continued to move through the region.

A similar caution was posted for the I-68 corridor in West Virginia and extreme western Maryland.
