All aboard the ‘pineapple express’ for showers in Steamboat

April was the second wettest in nine years.

STEAMBOAT SPRINGS — If April showers bring green grass, then the upper Yampa Valley and Steamboat Springs could see a color change in the  surrounding meadows during the second week of the month, after a “pineapple express,” an atmospheric river event, passes through the area April 6 to 8.

As a steady cold rain fell here Friday afternoon, National Weather Service meteorologist Mike Charnick said he expected the steady rain to continue until a lull arrived in the early morning hours Saturday.

“Saturday afternoon it could ramp up again, and there's even a possibility of thunder up toward the Steamboat area," Charnick said.

He expected more rain overnight Saturday, changing to snow on Sunday morning.

The National Weather Service describes atmospheric rivers as relatively narrow regions in the atmosphere that are responsible for most of the transport of water vapor from the West Coast. When an atmospheric river originates in the Pacific Ocean surrounding the Hawaiian Islands, it's dubbed a "pineapple express."

Beyond Monday, April 9, Steamboat's weather won't remind anyone of Maui, but the temperatures could become warm enough to inspire the grass to green up.

The National Weather Service foresees sunny skis and a high temperature of 58 degrees on Tuesday, April 10.

Intellicast agrees, calling for temperatures reaching 57 degrees on Wednesday and 55 on Thursday afternoon, before overnight temperatures dip again to 21 degrees, signaling the return of snow.

Intellicast calls for Steamboat to see periods of 1 to 3 inches of snow beginning during the night on Thursday, April 12, followed by more of the same during the day Friday and  repeating that trend Friday night, to set up the final weekend of the ski season.
