After a rather warm start to the season, November is about to show its true colors here in the Mid-Atlantic. A cold front will move across the region on Saturday, bringing gusty northwest winds and cooler temperatures. Some rain showers are possible Saturday evening throughout the region.
Temperatures will peak in the 60s and lower 70s across the region on Saturday, ahead of the cold front. Once the front moves through, colder air will rush into region through the overnight hours. Low temperatures will bottom out in the 30s and 40s.
The cooler air will plunge high temperatures on Sunday into the 40s and 30s. These cold temperatures will be accompanied with gusty northwest winds that could get between 20-30mph. Those winds will make it feel 5-15 degrees colder than it actually is (wind chills).
The strong northwest winds, out of Canada, will also help to generate lake-effect snows for western areas of Pennsylvania and New York. As much as 4-8" of snow will be possible near Erie, PA. Those lake-effect snow bands will likely reach the Appalachian Mountains in PA, western MD, and WV, with an inch or two possible. Some random flurries may try to make their way down into southern PA, northern MD, and northern VA on Sunday. However, I am not expecting any accumulation at this time.
This cold front will help to set the tone for the end of the month. It looks like we are heading into a below average time frame, in regards to temperatures, to end the month. Right now, I do not see any substantial threats from winter weather for the Mid-Atlantic, outside of the Mountains, for the next two weeks. However, I am tracking the potential for a storm around the time of Thanksgiving, that looks to give the Mid-Atlantic some rain.
