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).

* WHAT...A 60 percent chance of wind gusts exceeding 55 mph.

* WHERE...Northeastern Salt Lake Valley benches from Millcreek
northward.

* WHEN...From late Wednesday night through Friday morning.
Currently the strongest winds look to be Thursday night.

* IMPACTS...High winds may move loose debris, damage property and
cause power outages. Travel could be difficult due to
crosswinds, especially for high profile vehicles and vehicles
with trailers.
