PARK CITY, Utah — Although last week’s initial snow forecast came to nothing, local meteorologist Powder Buoy has spread the word about a possible few inches of snow on Tuesday.

The weather in the Cottonwoods and higher elevations on Tuesday and Wednesday will be in the 30s to 40s during the day, with lows of 0 to 0 degrees Celsius at night, accompanied by scattered thunderstorms.

While the model shows a total snowfall of nearly 15 inches for the event, the average lines show a potential of up to 6 inches, with a probability of several inches.

The Powder Buoy theory goes like this: The planet’s weather is interconnected, and storms that flow or form over the Pacific Ocean in the wintertime coincidentally pass over Hawaii, creating low-pressure areas and weather conditions that will eventually reach the mainland. NOAA’s ocean buoys, operated by the National Buoy Data Center, provide 24/7 data on a variety of metrics, including significant wave height. A spike in wave height indicates low pressure, which often signals approaching storms. It typically takes two weeks for such weather to reach the western U.S. from the buoys. While not perfect, this system serves as an early warning of storms. High-pressure areas in Utah can divert storms north, but the buoy pattern provides useful insights for planning ski trips.
