Much higher temperatures will work their way into Harrisburg into the weekend. The warmth will be accompanied by fog and some rain at times.
Record-challenging warmth is possible on Sunday with temperatures climbing well into the 60s.
As warmer, more moist air moves in, episodes of fog are possible in the regionwhich could slow travel.
While a few episodes of rain are possible, heavy rain will stay north and west of Harrisburg through much of the weekend. Melting snow over the Susquehanna watershed is forecast to not coincide with heavy rain. As a result major flooding is not forecast along the waterway and its tributaries. However, there can be significant rises on area streams and rivers.
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 2.9 degrees below the normal of 35.5 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.
