Pittsburgh: Record Warmth and Rain to Replace Snow and Cold

Much higher temperatures will continue to work their way into Pittsburgh through the weekend. The warmth will be accompanied by rain at times, areas of dense fog and possible flooding.

Record-challenging warmth is possible on Sunday with temperatures forecast to climb well into the 60s.

As warmer, more moist air moves in, episodes of fog are possible which could slow travel.

Rain is possible each day Friday through Sunday. Some of the rain later this weekend could be heavy at times, raising the risk for flash, urban and small stream flooding. There is a risk of moderate river flooding along the lesser rivers in parts of Ohio, where the rain will be the heaviest in the region.

According to AccuWeather.com Long Range Expert Paul Pastelok, "With the anticipated weather now through the end of the month, temperatures for December may average close to normal."

As of Dec. 16, temperatures have averaged 2.6 degrees below the normal of 34.1 degrees for the month to date.

Pastelok expects the weather pattern to erase much of this local temperature deficit by the end of the month with well above-average warmth forecast late this week into the weekend.

"There will still be a few chilly episodes later in the month, but not to the extreme of what we have experienced during late November into early December," Pastelok stated.

The warmup will not mean an end to snowstorms for the upcoming winter.
