Steamboat sees rainfall from jet stream to start September

Michael Schrantz

— After an August with below-average rainfall, Steamboat started September with a thunderstorm that hung around from Sunday evening into early Monday.

Local weather observer Art Judson measured 0.24 inches of rain Monday morning at his monitoring station between downtown and the mountain. Another Steamboat monitoring station in the Sanctuary measured 0.44 inches. A map of Community Collaborative Rain, Hail and Snow Network monitoring stations is available here.

Tom Renwick, a forecaster with the National Weather Service in Grand Junction, said the jet stream has been moving across Colorado for the past couple of days, but it just clipped Steamboat on Sunday.

The strongest part of the jet stream has moved on and is well to the northeast, over South Dakota and Minnesota, Renwick said.

Renwick said that the tropical flow from Hurricane Ilena, coming off Mexico's Baja Peninsula, added to the moisture in the atmosphere.

"I'd hazard a guess that moisture reached you," he said Monday.

The average precipitation for September in Steamboat is 1.8 inches, according to the National Weather Service. Steamboat closed out August with 0.58 inches of precipitation as measured at a monitoring site just east of downtown, compared to the monthly average of 1.71 inches. Judson measured 0.75 inches for August at his station.

There is little chance for more rain in Steamboat through next week. The week’s forecast calls for mostly sunny skies and high temperatures beginning in the 80s before dropping into the high 70s by the weekend. The lack of cloud cover could push nightly lows a few degrees colder, but overall, temperatures should remain above average.
