Area Forecast Discussion
National Weather Service Salt Lake City UT
905 PM MDT Sat Oct 15 2016

.SYNOPSIS...A series of fast-moving Pacific storm systems will
impact mainly northern Utah and southwest Wyoming through the
first half of the upcoming week. High pressure will return for the
latter half of the week.


.DISCUSSION...Unseasonably mild southwest flow is over the CWA
this eve downstream from a broad upper trof that continues to
cover much of the Gulf of Alaska. The next in the series of short
waves to eject out of the main trof is moving inland thru the
PacNW states heading towards the nrn Rockies.

This wave passes to our north Sun morning but does push its
associated cold front into nrn UT south to about Provo with the
best chance of rain from about OGD north.

Ahead of this wave the south winds will stay gusty overnight. They
have dropped off from this afternoon and cancelled wind advisory
earlier. Winds look to pick up again across much of srn UT on Sun
south of the front with speeds similar to today.

Frontal boundary and associated precip band lifts N late Sun thru
the eve as next short wave approaches. This next wave brings a
good portion of the colder air with the main trof inland with it
pushing into UT after midnight with fairly widespread precip
across the nrn CWA. This tapers off and turns showery by midday.

Updated earlier to lower pops overnight outside of the far
northern CWA and to cancel Wind Advisory. Also trimmed the
southern extent of pops back a bit for Sunday. No additional
updates planned.


.AVIATION...Gusty southerly winds will continue at the SLC
terminal through the night and into Sunday morning. A cold front
will cross the airfield between about 14-16z switching winds to
northerly. VFR conditions are expected through the TAF period.
Cigs could lower to around 7000 ft with the front.
