With the notable exception of the usually dry Southwest, Easter over most of the nation was sunny with balmy temperatures, including some record-breakers. But more than an inch of rain fell in Phoenix, causing flooding that sent children splashing into the streets and floating through neighborhoods on inner tubes and pool rafts, and snow advisories were posted over the western and central mountains of Arizona, where about nine inches of new, wet snow fell overnight near Flagstaff. In Pittsburgh, Pa., the sun burned off an early morning fog, and temperatures rose to 71. “This is spring here, I think,” forecaster Lou Giordano said. Spring-like weather also greeted churchgoers in New England. Sunny skies warmed people out in their spring finery on New York’s 5th Avenue. Record highs were set or tied with readings of 76 in South Bend, Ind.; 77 in Beckley, W. Va., and 84 in Norfolk, Neb.
