Area Forecast Discussion
National Weather Service Salt Lake City UT
947 AM MDT Sat Oct 29 2016

.SYNOPSIS...High pressure aloft will strengthen over Utah today,
then shift east of the state tonight. A mild and increasingly
strong southwest flow will exist over the eastern Great Basin
through Sunday. A Pacific storm system will cross mainly northern
portions of the area late Sunday afternoon through early Monday.

&&

.DISCUSSION...The shortwave ridge building over the forecast area
this morning will shift off to the east tonight. A substantial
amounts of low-level moisture remains over Utah at this time.
Expecting scattered and mostly terrain-tied convective cloud to
result from this moisture through the afternoon hours. Can not
rule out a few showers this afternoon, though with the dynamic
subsidence underneath the ridge would doubt anything significant
will develop today.

Anticipating a rather windy day across much of the forecast area
on Sunday. Increasing southwest flow tonight/Sunday between the
ridge axis to the east and the advancing southern end of the
eastern Pacific trough will supply the upper-level support for
strong southerly winds. The latest 12z guidance in so far still
place 50+ knot near 700mb southerly winds over western Utah ahead
of the strengthening surface front in Nevada Sunday afternoon.
This synoptic pattern is ideal for very strong and gusty surface
winds across all of western Utah, with speeds running at the high
end of wind advisory criteria or even in high wind warning
criteria. Will likely be issuing some form of wind highlights in
the afternoon forecast package.

The above mentioned trough will weaken a bit as it ejects east-
northeast through the Great Basin Sunday through Sunday night.
Still looking at a solid low-level reflection of this feature as
it moves through the northern two-thirds of the Utah/southwest
Wyoming late Sunday afternoon/evening. Good low-level forcing will
exist along the baroclinic zone, with the best mid-level dynamic
and thermal support for deeper convection remaining over the far
north during the evening. The period and location of the strongest
convective precip will likely remain across the far north during
the evening, with lighter but still organized showers continuing
along the baroclinic zone as it sags into central Utah later
Sunday night.

No updates planned at this time for the short term forecast.

&&

.AVIATION...The high pressure aloft strengthening across Utah
this morning will shift to the east of the area late this
afternoon/tonight. Any lingering showers should remain tied to the
surrounding higher terrain, with scattered clouds based above
10kft at the terminal.

Increasing southerly flow aloft will support south surface winds
much of today. These winds initially will be light through much of
this morning, then increase and become gusty during the afternoon.
Can not rule out a brief shift to light northwest winds after 22z,
follow by south winds returning early this evening. Winds will
pick up again late tonight through the day Sunday ahead of an
approaching cold front.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...None.
WY...None.
