The deep snow has already persuaded Canyons resort to extend its planned closing date by a week to April 17.
Alta, Brighton and Brian Head resorts all plan to be open through Easter Sunday. Alta will close during the week after Easter and reopen for the April 29-May 1 weekend.
Snowbird, just down from Alta, is scheduled to remain open through Memorial Day.
"Like in years past, if the snowpack is good and there is interest we will keep going beyond Memorial Day," said Snowbird spokesman Jared Ishkanian.
Snowbird has eclipsed the 600-inch mark for snow the past three years, and if last April is any indication, the Little Cottonwood Canyon resort may do it again.
"April turned out to be our snowiest month last season," Ishkanian said. "We had 144 inches alone in April of 2010."
Brian McInerney, a hydrologist with National Weather Service office in Salt Lake, said the La Niña weather pattern that usually produces better than average snowpack for the Utah mountains led to an active winter.
The storms will continue with three events occurring between Thursday and Sunday. While the valleys of Utah will see mostly rain over those days with just a smattering of snow sticking to the grass on the upper benches the high mountains will see snow piling up.
McInerney expects 4 to 8 inches during the day Thursday, with the biggest dump happening Friday morning with 8-14 inches of snow in the higher elevations. The last storm will hit sometime Saturday night with a yet unknown intensity. Projected closing dates for Utah resorts
Many Utah resorts already have surpassed 500 inches of snowfall this winter and, if the snow continues to fly, there is a chance 600 inches could be reached. Here is a list of projected closing dates, but some resorts may stay open longer if snow conditions allow.
