Ben Sessions, Farmington Elementary third-grader, has fun with his two pet frogs, but he wonders if they will hibernate now that colder temperatures are not far away. High temperatures of near 60 degrees were expected Tuesday in the Salt Lake City, Ogden and Provo area. It will be partly cloudy Tuesday and a little warmer, with highs 60 to 65. But a cold front was expected to brush northern Utah Monday. National Weather Service forecasters said a slight chance of rain was possible Monday. It will be become partly cloudy Monday night and Tuesday. Lows tonight will range between 35 and 40 degrees.
