Before you pass the gravy, be sure to grab a hat or scarf. Thanksgiving Day temperatures are expected to be among the coldest in two decades.

Several weather forecasts expect temperatures Wednesday night and early Thursday morning to reach the low 20s, said Jon Richards, a weather enthusiast who runs lawrencevilleweather.com. The National Weather Service forecast said Thanksgiving Day will have a high temperature of 46 degrees and a low of 31.

“The rain that we had, the storm has pretty much moved north and is troubling all the folks in Pennsylvania, New York, Massachusetts and Vermont,” Richards said Wednesday afternoon. “As the cold front comes through, it’s going to clear up. By tonight, we should end up with clear weather.”

Recent Novembers have seen temperatures in the high 20s, such as 28 degrees in 2010, 2011 and 2012. But not since the late 1980s has the metro Atlanta area recorded a low in the low 20s, Richards said.

Normal temperatures for Wednesday are a high of 60, and a low of 40.

While Richards said a long range forecast for December calls for colder-than-normal temperatures, the rest of this weekend should be warmer. Each of the three days after Thanksgiving are expected to have highs of at least 50, with Friday the warmest of the weekend with a high of 55 degrees.
