Rain, hail and a brief thunderstorm in Bountiful Sunday are sure signs spring is on its way.
But the moisture is still adding to the snow depths at Wasatch Front ski areas where as many as 8 new inches fell on the slopes Sunday."I had my doubts we would ever see (spring) this year," said William J. Alder, meteorologist in charge at the National Weather Service in Salt Lake.
Warming conditions Friday and Saturday were followed Sunday morning with light rain showers in south Davis County and most of Salt Lake County. "Then the grand finale was a thunderstorm in the afternoon Sunday," Alder said.
The thunderstorm formed in the west desert Sunday, then rolled east toward the Wasatch Mountains shortly after 4 p.m., dropping rain, snow pellets and pea- to quarter-sized hail in Bountiful and northern Salt Lake County. "It's a good sign that spring is around," Alder said.
The heaviest rain fell in the Sugar House and Avenues areas of Salt Lake where .48 inch fell during the day Sunday. Accumulations of .13 inch were recorded at the Salt Lake International Airport and .15 inch fell in the Holladay area.
"The storm was mainly concentrated from Ogden south to the north part of Utah County," Alder said, with rain falling as far east as Coalville.
Wet, heavy spring snow fell Sunday at area ski resorts: 7 inches at Alta, 8 inches at Brighton and Solitude, 5 inches at Deer Valley, Park City and Park West and 1 inch at Snow Basin.
Alta now has a base of 106 inches of snow, and Brighton, Solitude and Snowbird have 94, 88 and 83 inches, respectively.
Warm daytime temperatures have melted most of the snow that has been piling up on curbs and sidewalks at lower elevations. Below-freezing temperatures at night have paced the snowmelt. Alder said that trend should continue.
Afternoon clouds are expected Tuesday evening and Wednesday. Otherwise there should be very little atmospheric weather activity through the week, Alder said.
Wasatch Front temperatures should be in the 20s to lower 30s at night with high daytime temperatures in the 40s and into the low 50s by the end of the week.
Heavy, melting snow could increase the likelihood of slush and avalanche problems at elevations of 6,000 to 7,000 feet, Alder said.
