One thing we might not be quite so thankful for Thursday is the weather.

Temperatures will swing drastically into the 40s this Thanksgiving day, which is some significant whiplash after 70s Wednesday, according to 7News First Alert Senior Meteorologist Brian van de Graaff.

“Mother Nature, reminding us it is indeed fall for your Thanksgiving,” van de Graaff said. “We’ll have clouds and a little sunshine, but I think those clouds are continue to win out.”

The culprit is a west-northwesterly wind that’s keeping cold air in the region, “meaning temperatures will feel more like the 30s when you factor in those breezes,” van de Graaff said.

Overnight temperatures are expected to be in the 30s in downtown D.C., but the suburbs could go as low as the upper 20s.
