Area forecast discussion 
National Weather Service Salt Lake City Utah
925 PM MDT Monday Oct 20 2014

Synopsis...a dry and mild southwesterly flow will give way to a
Pacific cold front on Tuesday. Dry and mild southwest flow will
return for Thursday and Friday.



&&

Discussion...a shortwave trough currently situated along the
Oregon/norcal coastline is forecast to continue inland
overnight...before lifting east-northeast across the northern Great Basin
during the day Tuesday. Large scale ascent is forecast to spread
across northern Utah later tonight with the approach of this
trough...before becoming maximized Tuesday morning as the surface
front sweeps across northern Utah. This will bring a good chance for
showers with a small threat for thunderstorms Tuesday
morning...with the chance for precipitation shifting into central
Utah and diminishing along the frontal boundary during the
afternoon/evening hours as the upper wave lifts away from the
region. Snow levels look to remain in the 9-10 kft through the
duration of the precipitation event with any accumulation remaining
minimal. Going forecast depicts this idea fairly well...and no
updates currently planned.

&&

Aviation...southerly winds at kslc will increase
overnight...before shifting to the northwest around 15z Saturday
with the passage of a cold front. Behind the front ceilings will
likely lower below 7 kft through the remainder of the morning
hours...with a 30 percent chance of temporary MVFR ceilings with
heavier rain showers.

&&

Slc watches/warnings/advisories...
Utah...none.
Wyoming...none.
