At 2 p.m., May 18, the National Weather Service issued a winter weather advisory for the Hill.

This is true, and not a May Fool's joke.

The Advisory is from 5 a.m., Sunday, May 20 through 5 a.m., Monday, May 21.

The NWS warns, 

"A late season storm will create periods of snowfall Sunday and
Sunday night, with accumulations expected above 6000 ft. Heavy
showers and thunderstorms could create higher snowfall rates at
times, with greatest accumulations expected late Sunday. Snow will
make driving hazardous at times."

Accumulations of 1 to 3 inches are possible, likely, between 6,000 and 7,000 feet. More up to 8,000 feet and more than 8 inches above 8,000 feet.

And a wind advisory until Tuesday night.
