A group of friends bask in springlike weather at Cardiff Fork in Big Cottonwood Canyon Monday, even though Tuesday marks the first official day of spring. At 2:19, when the sun positions itself directly over the equator - marking the vernal equinox -winter will be officially over. But above average temperatures made it seem like spring had sprung days ago. The low temperature Tuesday was 47 degrees, with the high expected to reach 65 - compared to a normal high of 53 degrees and a normal low of 31 degrees. Warmer-than-normal temperatures are expected throughout the week.
