We didn't just break the record high temperature for Sunday; we shattered it as we hit the 70 degree mark at the Harrisburg International Airport early Sunday morning. Temperatures remained in the 60s through the afternoon as showers fell, but now we begin to take the readings back to more seasonable levels just in time for Christmas.
The cold front will push east of our region tonight, and that will allow for a wind shift and cooler air starting to filter into the region. The high of 52 for Monday will likely occur early in the day with steady, or slowly falling temperatures into the afternoon. The cold front will crawl just to our east, and allow an area of low pressure to develop and ride up the east coast. That means rain will redevelop toward dawn, and overspread most of the region through Monday morning and into the early afternoon before wrapping up. The best chance for rain appears to be the farther east one goes. In general, expect anything from just a light shower west, to near another 1" of rain in our eastern counties.
By Christmas Eve Day and Christmas Day, temperatures will be back to normal, if not slightly below, with afternoon highs in the 30s. There is the chance for a few flurries on Christmas Eve, but it wouldn't be enough snow to cause any travel troubles; just add a nice seasonal touch to the holiday with the recent snows wiped out by the weekend warmth.
The rest of the week looks quiet, and seasonal as well.
