“Temperatures could be dropping quickly below the freezing mark, due to the light winds and those cooler than average temperatures,” Storm Team4 Meteorologist Clay Anderson said.

To prepare for the cold, Anderson recommends outdoor plants be brought inside.

“This area here, could see temperatures 31, 32 degrees, and that’s why you want to bring those plants, or whatever you are trying to grow, outside, inside,” Anderson said.

D.C. has activated this season’s first hypothermia alert. It is set to begin at 6 p.m. tonight and will continue until conditions approve, according to a release from the D.C. Mayors office.

The alert asks residents to help neighbors experiencing homelessness get out of the cold. Transporation to a shelter can be requested by calling 202-399-7093 or 311.

Last week, temperatures made some days feel more like the month of September. On Saturday, temperatures reached 70 degrees. On Sunday, temperatures cooled down to the 40s-50s.

A December feel is expected in the week ahead as daytime highs are expected to stay below 50 all week. Monday will be breezy and sunny with temps in the 40s-50s. A freeze could happen Monday evening into Tuesday morning as well.
