A cold frontal boundary will push through the western half of Utah later this afternoon through the mid-to-late evening hours. Along this boundary, a line of moderate to heavy precipitation is expected, mostly in the form of rain. There is a low chance (25 percent likelihood) that a transition to snow occurs in the areas of heavier precipitation rates as the boundary moves through. The most likely period that this would occur will be between 5 PM and 7PM along the I-80 corridor west of the Tooele Valley, 7 PM and 10 PM along the Wasatch Front, and between 9 PM to 12AM along the I-15 corridor between Nephi and Cedar City. Scenario 1 (most likely): The frontal boundary pushes through the western half of Utah, bringing moderate to high intensity precipitation in the form of rain across all areas. Snow may mix in toward the end of the banded precipitation, however, significant accumulations of snowfall will not be expected. Scenario 2 (less likely): The frontal boundary pushes through the western half of Utah. bringing high intensity precipitation rates that force snow levels down to valley floors. If this occurs, disruptions to travel are likely along the I-80 and I-15 corridors, especially on the higher elevation passes. Possible snow accumulations with a rapid transition to snowfall will be 1 to 3 inches. Again, this is a low probability event (about 25 percent chance or less). $$ For more information from NOAA/s National Weather Service visit... http://weather.gov/saltlakecity For information on potential travel impacts visit... http://www.udottraffic.utah.gov/roadweatherforecast.aspx
