Snow has turned to rain across much of the region, leading the National Weather Service to change its morning winter weather advisory to a flood watch until midnight.

Rain will continue through the night and is expected to taper off by Thursday morning, with temperatures staying above freezing, said meteorologist Lee Hendricks, who works in the agency’s Moon office.

“The rain should help with melting the snow,” he said. “Some streams and creeks may overflow their banks.”

The flood watch applies to parts of Greene, Fayette, Westmoreland and Washington counties.

Snowfall rates of up to 1 inch per hour during the morning rush hour led to a quick accumulation of snow across the region, hampering the commute and blanketing the region with snow.

The National Weather Service in Moon issued a winter weather advisory for most of Western Pennsylvania, in effect until noon Wednesday. Most of the Pittsburgh region saw 4 inches or more of snow, with some light ice accumulations as the snow transitions to a wintry mix and then rain during the early afternoon.

Many school districts and other organizations were either closed or operated on a two-hour delay.

Dozens of inbound and outbound flights at Pittsburgh International were canceled. All on-street bus routes were delayed for about an hour due to traffic and road conditions, the Port Authority of Allegheny County tweeted.

Several Pennsylvania roads had travel restrictions. PennDOT reduced the speed limit to 45 mph on I-70, I-79, I-579, the Parkways North, East and West, Route 22/30 and Route 28. Weather conditions also closed the I-279 HOV lanes.

A Port Authority bus struck a building along Seneca Street in Pittsburgh’s Uptown neighborhood after it slid backwards and jackknifed on ice. No one was injured.

A winter storm warning was issued for the ridges of Westmoreland County, where up to 7 inches of snow could fall. Central and eastern portions of the state also were under a winter storm warning.

The NWS issued winter storm alerts for several parts of the Ohio Valley and mid-Atlantic starting late Tuesday.
