WASHINGTON —Climate protesters — or those who were just out and about in D.C. on Saturday — felt the heat: the high of 91-degrees tied a record set in 1974.

Saturday also marked the first time this year that D.C.  temperatures reached the 90s.

[related_gallery align=”right”]Storm Team 4 Meteorologist Amelia Draper said temperatures Saturday were 20 degrees above normal. She said temperatures in this region usually don’t hit the 90-degree mark until May 17.

Temperatures from Dulles International Airport reached 89 degrees, beating a 1996 record of  88.

What’s causing the unseasonable heat? Southern winds and synoptic patterns are allowing the warmth in, said Draper.

The heat is likely to continue on Sunday and the beginning of the week. The D.C. area will reach a high in the low 80s on Sunday. Temperatures are also expected to reach the low 80s on Monday.
